Quasi-turbine- The very efficient rotary engine in Mechanical field.
The document presents the quasi-turbine (QURBINE) as the next generation rotary engine. It summarizes that piston engines are inefficient due to intermittent combustion and many reciprocating parts. The Wankel rotary engine also has issues with sealing and emissions. The QURBINE uses a four-sided rotor in an oval housing to achieve continuous combustion via photo-detonation, resulting in higher power, zero vibration, less noise and pollution compared to piston and Wankel engines. While construction of the rotor presents challenges, the QURBINE has applications in aircraft, power tools, and vehicles due to its efficiency.
Quasi turbine engine
The document describes the Quasi Turbine engine, a proposed pistonless rotary engine. It has a rhomboidal rotor with hinged sides that allow for increased compression and expansion ratios compared to the Wankel engine. The Quasi Turbine has fewer parts than pistons engines, is more efficient, produces high torque at low RPM, and has potential applications in aviation, power tools, vehicles and pumps due to its compact size, lack of vibration, and mechanical simplicity. The engine works through intake, compression, combustion and exhaust cycles without the use of pistons or crankshafts.

The document summarizes a seminar presentation on the quasi turbine engine, a proposed new type of rotary engine. It describes some limitations of current reciprocating and Wankel rotary engines and then outlines the history and design of the quasi turbine engine. The quasi turbine uses a rhomboidal rotor to provide compression and expansion like a Wankel engine but allows higher volume ratios through hinged edges. It produces high torque at low RPM with fewer parts, less noise/vibration, and higher efficiency than other engine types. While still in development, the quasi turbine shows promise for applications requiring power-to-weight ratio like aviation and may see broader use in the future.
Quasi turbine engine
The Saint-Hilaire family patented the Quasi turbine engine in 1996 as an improvement on the standard Wankel or rotary engine. The Quasi turbine uses a four-element rotor within a housing to divide the space into four combustion chambers. It operates on a continuous combustion principle with no vibrations or dead times. The engine aims to be compact, efficient, and able to run on multiple fuel types with high torque at low RPM.
Quasi Turbine Engine
The Quasiturbine engine was developed as an improvement on the standard Wankel or rotary engine. Unlike piston or standard rotary engines, the Quasiturbine's four-element rotor and carriages allow it to withstand the high pressures needed for photo-detonation combustion. This makes the Quasiturbine more efficient than piston or standard rotary engines. The Quasiturbine engine arranges the four strokes of combustion sequentially around an oval housing without needing a crankshaft. This produces power with each revolution rather than every other revolution as in piston engines. While still in development, the Quasiturbine engine aims to be simpler and more efficient than conventional engines.

The document discusses the quasi turbine engine, a pistonless rotary engine. It has a deformable rotor made of blades hinged at the vertices that is enclosed in an oval housing. The rotor undergoes compression and expansion similar to the Wankel engine. There are two types - one without a carriage where the rotor seals directly to the housing, and one with a carriage that has ports for spark plugs, intake, and exhaust. The quasi turbine operates on the same four stroke cycle as an internal combustion engine but does not require pistons or a crankshaft. It provides advantages like simplicity, reduced vibration, higher torque at lower RPMs, and increased fuel efficiency. However, it is still in development and not yet
Wankel
The Wankel engine is a type of internal combustion engine that uses a rotary design instead of pistons. It was developed in 1951 by Felix Wankel and uses a four-stroke combustion cycle. The key components are a triangular rotor that rotates inside an oval-shaped housing, with the rotor acting like a piston in a traditional engine. The rotor spins on an eccentric output shaft, turning three times for every one revolution to power the vehicle. Benefits include simplicity, high power-to-weight ratio, and smooth operation, though fuel efficiency is reduced compared to piston engines. It has seen limited automotive use primarily in Mazda vehicles.

1 wankel engine assaignment
The document summarizes the Wankel rotary combustion engine. It describes the engine's design which uses an eccentric rotary motion rather than reciprocating pistons. This allows for advantages like simplicity, compactness, and high power-to-weight ratio. The engine uses three rotor tips moving inside an oval housing to produce three power pulses per revolution. It operates on a four-stroke cycle like a piston engine. The Wankel engine has fewer moving parts than piston engines and no valves, allowing it to run more smoothly with less vibration at high RPMs. It can achieve high performance at high speeds due to lower friction and longer intake/exhaust strokes without valves restricting airflow.
Wankel engine
The Wankel engine uses an eccentric rotary design instead of pistons, where the four-stroke cycle occurs inside an oval housing and triangle-shaped rotor. It functions as a variable-volume progressing-cavity system with three cavities repeating the cycle. Wankel engines are lighter, simpler, and have fewer moving parts than equivalent piston engines. They provide high reliability, smooth power delivery, and a high power-to-weight ratio, but consume more fuel and produce more unburnt hydrocarbons than four-stroke engines. Wankel engines are used in cars, motorcycles, and aircraft for their light weight, small size, and durability in all weather. Mazda has designed some of the best Wankel

Wankel engine
The Wankel engine uses an eccentric rotary design where the four strokes of a piston engine occur in the space between a three-sided rotor and a housing, rather than using pistons. It delivers advantages like simplicity, compactness, and high power-to-weight ratio over piston engines. Early prototypes were developed in the 1950s, and companies have since licensed the design and improved it. While it has better power density than pistons, Wankel engines face challenges with sealing and emissions that have limited their widespread adoption.
Rotary Engines
This document compares piston engines and rotary engines. It discusses their design differences, performance, fuel consumption, and emissions. While rotary engines can provide good performance in compact designs, they typically consume more fuel than piston engines due to their combustion chamber shape and lower compression ratio. Rotary engines also emit more carbon monoxide and unburnt hydrocarbons, making them difficult to regulate under emission standards. Therefore, the document concludes that rotary engines are best suited for applications requiring high performance or a lightweight design, but are less optimal for fuel efficiency or meeting emission regulations compared to piston engines.
Wankel engine
The document discusses the Wankel rotary engine, including:
- Its invention in 1954 by German engineer Felix Wankel and use in cars like the Mazda RX-8.
- How it works using a spinning rotor and three chambers instead of pistons, making it lighter and smoother.
- The challenges in designing it, such as getting measurements correct, preventing interference, and assembling the complex parts.
5 stroke ic engine
The 5-stroke internal combustion engine developed by Ilmor utilizes two firing cylinders that exhaust alternately into a central expansion cylinder, extracting extra work. This allows the engine to run with an expansion ratio of 14.5:1 like a diesel while achieving fuel consumption of only 226 g/kWh. The expansion and compression processes are decoupled, enabling independent optimization. Initial running of the prototype produced impressive fuel efficiency over a wide operating range due to greater work extraction in the low pressure cylinder upon knock onset, providing self-compensation.
Rotary Engines
The document summarizes the key aspects of a Wankel rotary engine. It describes how a rotary engine works differently than a piston engine by having each step of the combustion process occur in a dedicated section of the oval-shaped housing as the rotor continuously rotates. It also notes that rotary engines have fewer moving parts, provide smoother power delivery, and have parts that move more slowly compared to piston engines. However, rotary engines can be more difficult to design to meet emissions regulations and typically have lower thermodynamic efficiency.
ball piston engine
The document is a seminar presentation on the ball piston engine. It includes sections on the introduction, mode of operation, design features, material selection, working, lubrication, advantages, disadvantages, applications, and conclusion of the ball piston engine. The ball piston engine uses two intertwined rotors instead of reciprocating pistons, where spherical pistons rotate in a spherical housing with slightly inclined rotational axes to create "strokes" and volume changes in the working chambers. It has potential for higher efficiency than piston engines due to lower friction and more power extraction on the power stroke.
6 stroke engine
this is beare type six stroke engine invented by malcom beare. easy mechanism better power production better efficiency more than 4Stroke.
6 stroke engine
The document discusses a six-stroke engine which aims to improve fuel efficiency and reduce emissions compared to traditional four-stroke engines. It works by adding two additional strokes: after the four-stroke cycle is completed, fresh air is drawn in and expelled to capture waste heat for a secondary power stroke. This provides two power strokes per cycle and can increase efficiency by 40% while reducing pollution by up to 65%. However, the engine is more complex with more components and lower power per cylinder compared to four-stroke designs. Widespread adoption in automobiles could significantly reduce fuel use and emissions globally if efficiency gains are realized.
Wankel engine
This presentation discusses the Wankel engine. A group of 5 students will present on the topic for an automobile engineering department.

However, emissions are difficult to control and manufacturing costs are high. The Wankel engine has been used in motorcycles, cars and aircraft.
6 stroke petrol engine
This document discusses the six-stroke engine, including its types and working. The six-stroke engine incorporates an additional stroke to the conventional four-stroke engine, introducing a second power stroke. There are three main types - the Crower, Beare Head, and Bajulaz engines. The Crower design injects water after the exhaust stroke to produce steam for an additional power stroke, while reducing fuel consumption by 40%. The Bajulaz engine provides two expansions in six strokes, dramatically reducing pollution while using multiple fuel types, and maintains costs comparable to a four-stroke engine. Six-stroke engines could potentially reduce fuel consumption and pollution levels without significant performance impacts.

6 stroke engine
This document describes two 6-stroke engine designs that aim to improve fuel efficiency over traditional 4-stroke engines. The first is Bruce Crower's 6-stroke engine, which captures wasted heat from the 4-stroke cycle to power an additional steam stroke. The second is the Beare dual opposed piston 6-stroke engine, which replaces the cylinder head with an overhead piston arrangement, combining a 4-stroke bottom end with a 2-stroke head cycle. Both designs are analyzed against traditional 4-stroke engines and are found to increase power and torque output while improving fuel economy.
My six stroke engine
This document discusses six-stroke engines as a more efficient alternative to four-stroke engines. It describes two main types of six-stroke engine designs: single piston and opposed piston. Several single piston engine examples are provided, including the Griffin engine which uses a heated vaporizer to improve fuel efficiency. The Bajulaz engine is also described, which uses two additional chambers above each cylinder for combustion and air preheating. Benefits over four-stroke engines include increased power and torque, lower emissions, and simpler design. However, six-stroke engines also have increased complexity and cost compared to four-stroke engines. The document suggests they may be best suited for applications like racing vehicles, heavy machinery, and stationary engines.
Duke engines
This document discusses the Duke engine, which is a type of reciprocating engine with pistons arranged around an output shaft parallel to the shaft. The key advantage is the compact, cylindrical design with cylinders arranged parallel to the crank shaft. The main elements are the barrel, which refers to the cylindrical shape, and the swash plate, which translates rotating shaft motion to reciprocating piston motion. Testing has shown the Duke engine can be up to 19% lighter and 36% smaller than conventional engines while maintaining comparable performance. It can run on various fuels and has applications in vehicles, marine uses, and power generation due to its advantages of high efficiency, low vibration, and compact size.

This document discusses magnetorheological abrasive flow finishing (MRAFF), a process that uses a magnetorheological polishing fluid to precisely control finishing forces and achieve a final surface finish. An experimental setup was designed to study the process, consisting of MR polishing fluid cylinders, hydraulic actuators, an electromagnet, and workpiece fixture. Experiments showed no surface roughness change at zero magnetic field but improved surface finish at higher fields, as the MR fluid's viscosity changes with applied field strength. The MRAFF process involves extruding the MR fluid through the workpiece under a magnetic field, where abrasives held by iron chains rub peaks and shear material in a controllable way set by the field strength.

There are two main types of bearings: ball bearings, which use balls to separate the surfaces, and roller bearings, which use rollers. Roller bearings can carry greater loads than ball bearings in the same space due to line contact versus point contact. Magnetic bearings support loads using magnetic levitation without physical contact through the use of electromagnets and a control system. They have advantages like low friction, lack of wear, and ability to run without lubrication.

Magneto rheological fluid ppt
Magneto rheological fluids are smart fluids that change viscosity when exposed to a magnetic field. They are usually oil-based liquids containing magnetic particles. When a magnetic field is applied, the particles align and increase the fluid's viscosity, allowing it to be used in dampers, shock absorbers, and other devices. Magneto rheological fluids operate in three modes - flow, shear, and squeeze-flow - and have applications in fields like automotive, prosthetics, optics, and vibration damping. While expensive, they provide advantages for damping and control applications and continued research may expand their uses in areas like enhancing body armor, aircraft safety, and earthquake-proof buildings.

Replication allows data from a MySQL master database to be synchronized with one or more slave databases. The master records all data changes in its binary log. Slave databases connect to the master and receive the binary log transactions, which they then apply locally to stay synchronized with the master database. Replication can be used for load balancing reads across multiple slave servers or for high availability by failing over to a slave if the master fails.

Six stroke-engine-presenation-by vijay b r
The majority of the actual internal combustion engines, operating on different cycles have one common feature, combustion occurring in the cylinder after each compression, resulting in gas expansion that acts directly on the piston (work) and limited to 180 degrees of crankshaft angle.
According to its mechanical design, the six-stroke engine with external and internal combustion and double flow is similar to the actual internal reciprocating combustion engine. Six-stroke engine differentiates itself due to its thermodynamics cycle and a modified cylinder having one combustion chamber and one air heating chamber, both independent from cylinder. Combustion does not occur within the cylinder but in the supplementary combustion chamber, does not act immediately on the piston, and its duration is independent from the 180 degrees of crankshaft rotation that occurs during the expansion of the combustion gases (work).
The combustion chamber is kept inside the air heating chamber. Air pressure in the heating chamber increases and generate power for a supplementary work stroke by virtue of heat exchange through glowing combustion chamber walls. Several advantages result from this, one very important being the increase in thermal efficiency. In the present time internal combustion engine, important calorific losses are generated due to the required cooling of the combustion chamber walls.
In six-stroke cycle, two parallel functions occur in two chambers which result in eight event cycle: four event internal combustion cycle and four event external combustion cycles.
The first cycle of four events is of external combustion. It includes Event 1: pure air intake in the cylinder. Event 2: pure air compression in the heating chamber. Event 3: keeping pure air pressure in closed chamber where a maximum heat exchange occurs with the combustion chambers walls, without direct action on the crankshaft. Event 4: expansion of the super heated air in the cylinder, work. During this four event's cycle, the pure air never comes in direct contact with the heating source. The second cycle of four events is of internal combustion. It includes Event 5: re-compressions of pure heated air in the combustion chamber. Events 6: fuel injection and combustion in closed combustion chamber, without direct action on the crankshaft.
Events 7: combustion gases expanding in the cylinder, work. Event 8: combustion gases exhaust.
During these four events, the air comes in direct contact with the heating source.
Four stroke petrol engine
The document discusses the four stroke petrol engine. It begins by introducing the four main components: the intake stroke where air-fuel mixture enters the combustion chamber, the compression stroke where the piston compresses the mixture, the power stroke where combustion occurs and the piston is pushed down, and the exhaust stroke where burnt gases are pushed out. It then explains each stroke in more detail and analyzes the thermodynamic process. Advantages include less fuel consumption and higher efficiency, while disadvantages are more complex design and higher costs. Applications include use in cars, motorcycles, boats and other small engines.
Six Stroke.pptx
The document describes different types of six-stroke engines, including the Bajulaz, Crower, and M4+2 engines. A six-stroke engine has two power strokes compared to the one power stroke of a conventional four-stroke engine. It captures wasted heat from the four-stroke cycle to power an additional stroke, improving efficiency. The Crower engine uses water injection to generate steam for an extra power stroke, reducing fuel consumption by 40%. Advantages of six-stroke engines include increased efficiency and reduced emissions, though they also have higher manufacturing costs.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
