Jet propulsion
Jet propulsion works by discharging a fluid to generate thrust in the opposite direction of the jet. There are two types of jet engines: air-breathing and non-air breathing. Air-breathing engines like turbojets, turbofans, ramjets, and pulsejets use atmospheric air, while non-air breathing rocket engines contain their own oxidizer and fuel. Rocket engines provide thrust through momentum change and pressure difference of the exhaust gases. They are self-contained and can operate in a vacuum but require a large amount of propellant.
1. clutch
A clutch is a mechanical device which engages and disengages power transmission especially from driving shaft to driven shaft.
TYPES OF CARBURETORS
A carburetor mixes air and fuel for combustion in an internal combustion engine. It contains several main parts including a venturi, float chamber, nozzles, and throttle valve. A carburetor uses venturi suction to draw fuel from the float chamber and mix it with air to supply the engine. The main types are updraft, downdraft, and horizontal based on airflow direction. Carburetors provide fuel metering and air-fuel ratio control for engines. While simpler than fuel injection, carburetors are less precise at mixing fuel and air.
Multipoint Fuel Injection System (MPFI)
This document discusses fuel injection systems, specifically multiport fuel injection (MPFI) and direct fuel injection (DFI) systems. It provides details on:
- The components and functioning of MPFI systems, including the air intake system, fuel delivery system, and electronic control system. It notes MPFI injects fuel into intake ports.
- The components and functioning of DFI systems, including high pressure fuel rails and injectors located in the cylinder. DFI allows for stratified charge and homogeneous operating modes.
- The advantages of DFI over MPFI, including more complete combustion, better temperature patterns during combustion, and reduced intake duct losses, leading to improved efficiency.
MULTI-POINT FUEL INJECTION SYSTEM
Multipoint fuel injection (MPFI) systems provide better control of the air-fuel ratio compared to carburetors. MPFI systems use multiple fuel injectors, with one injector per cylinder, to inject fuel into the engine's intake ports or manifold. This allows supplying the optimum air-fuel ratio to each cylinder for all operating conditions. MPFI systems are electronically controlled using sensors to monitor various engine parameters and optimize fuel delivery and emissions performance. While more complex than carburetors, MPFI systems improve fuel efficiency, power, and reduce emissions.
Front axle and steering system
1. Front wheels of the vehicle are mounted on front axles. It supports the weight of front part of the vehicle, facilitates steering, and absorbs shocks transmitted due to road surface irregularities.
2. There are different types of front axles including dead axles, live axles, and stub axles which connect to the front axle by king pins to allow steering of the front wheels.
3. The steering system includes components like the steering wheel, steering shaft, steering gearbox, steering linkage and wheels which work together to convert the rotational motion of the steering wheel into lateral motion of the wheels to steer the vehicle.
6 air brake system
The air brake system uses compressed air to apply pressure to brake pads to stop large heavy vehicles. It has several main components including a brake valve to control air flow, governors to regulate air pressure, air tanks to store compressed air, air compressors to fill the tanks, brake chambers that use air pressure to engage the brakes, and slack adjusters to ensure proper brake clearance.
Clutches ( Single Plate and Multi Plate)
A clutch connects and disconnects a vehicle's engine from its transmission. It allows the driver to smoothly start from a stop, change gears, and stop the vehicle while in gear. A clutch operates using friction between two surfaces - the clutch disc and pressure plate. When engaged, spring pressure holds the surfaces together to transmit torque. When disengaged by pressing the clutch pedal, the pressure is released and power is cut off. Common types are single and multi-plate clutches, with multi-plate versions able to transmit more torque due to multiple friction surfaces.

Clutches for automobile
The document discusses different types of clutches used in vehicles. It describes a clutch as a mechanical device that connects and disconnects two rotating shafts to facilitate transmission of power and motion. The main types discussed are single plate clutches, multi-plate clutches, cone clutches, and centrifugal clutches. A single plate clutch uses a flywheel, pressure plate, clutch disc/plate, and release bearing. A multi-plate clutch has multiple clutch plates to transmit higher torque. A cone clutch uses a cone shape for contact rather than plates. A centrifugal clutch uses centrifugal force from rotation to engage.
slides on clutches
A clutch connects and disconnects two rotating shafts to engage and disengage power transmission. It consists of a driving member, driven member, and operating member. Common types include friction clutches like disc and cone clutches. A single plate clutch uses one clutch plate between a flywheel and pressure plate to transmit power from an engine to transmission. A multi-plate clutch uses multiple plates to transmit higher torque for racing cars and heavy vehicles. A cone clutch uses two conical surfaces to transmit torque through wedging action and increased surface area. A centrifugal clutch engages more at higher speeds using centrifugal force and weighted arms to connect engine and output shafts.
Principles of carburetion
1) The document discusses the principles of carburetion, explaining how a carburetor works to provide an air-fuel mixture to engines. It mixes air and fuel through venturi suction and different metering systems that control the mixture at idle, acceleration, high speeds, and full power.
2) A carburetor uses atmospheric pressure, temperature, volatility, and atomization to control the evaporation of fuel into a vapor that can be mixed with air. Different parts of the carburetor like the float, jets, and chokes maintain the proper air-fuel ratio for starting and various engine conditions.
3) Issues like excessive fuel consumption, sluggish engine performance, poor idling,
Propeller shaft & universal joint
The document discusses various components that connect the transmission to the drive wheels, including the propeller shaft, universal joints, constant velocity joints, and slip joints. It provides details on the construction and function of each component. The propeller shaft transmits power from the transmission to the rear differential. Universal joints and constant velocity joints allow the shaft to transmit power through varying angles, while slip joints allow adjustments to the shaft length during vehicle movement.
Fuel Injection Systems
The document discusses fuel injection systems for internal combustion engines. It describes the key components and functions of fuel injection systems. The systems work to accurately meter and inject fuel into the combustion chamber at precise timings and rates to achieve proper mixing and combustion. Common components include the fuel tank, feed pump, injection pump, injector nozzle, and governor. The injection pump pressurizes and meters the fuel supply, while the nozzle atomizes the fuel into fine droplets for rapid mixing in the chamber.
Piston engine construction
The crankcase supports and encloses the crankshaft and provides an oil reservoir. It holds the engine parts in alignment and supports the cylinders and crankshaft. The crankshaft rotates within the crankcase and is supported by main bearing journals, with throws that account for the reciprocating motion of the pistons. The camshaft opens and closes the valves using lobes timed to the crankshaft.
Operation of centrifugal clutch
Centrifugal clutches use centrifugal force to connect two concentric shafts. They consist of shoes on the inside of a pulley rim that are pushed outward by centrifugal force as speed increases. At lower speeds, the shoes are held inward by springs and do not contact the driven shaft. As speed rises and centrifugal force overcomes the spring force, the shoes move outward to press against the driven shaft and transfer torque. Centrifugal clutches engage automatically as speed increases without any control mechanism, making them cheaper than other clutches, but they cannot transfer significant power and may slip under heavy loads or fail to engage reliably.
Supercharging | Internal Combustion Engine
The document discusses different types of superchargers used to increase the power output of internal combustion engines. It describes supercharging as increasing the inlet air density to provide more air to the engine. There are three main types discussed: centrifugal superchargers which are mechanically driven; roots superchargers which use lobes to force air into the intake; and vane superchargers which use spring-loaded vanes. The document also covers four arrangements for driving superchargers: gear-driven from the engine; with an exhaust turbine; coupled engine and turbine; and gear-driven with a free turbine.
6 rear axle drives
The document describes two types of rear axle drives: the Hotchkiss drive and the torque tube drive. The Hotchkiss drive uses two longitudinally mounted leaf springs connected to the frame with a fixed pivot in front and swinging shackles in back. A universal joint is used at each end of the propeller shaft to accommodate changes in shaft length from spring deflection. The torque tube drive uses a tubular torque tube that encloses the propeller shaft and is bolted to the axle casing. A universal joint and ball socket joint are used to allow the propeller shaft to angle within the torque tube as the suspension moves.
Types of fuel pumps
There are two main types of fuel pumps: mechanical and electrical. Mechanical fuel pumps use engine camshafts to drive diaphragms that push fuel through the pump, while electrical fuel pumps use electric motors located inside or inline with the fuel tank to draw and pressurize fuel for modern fuel injection systems. Within electrical fuel pumps there are in-tank and inline subtypes. Turbo pumps can also be used to further increase fuel pressure for high-performance engines.
Torque converter
A torque converter is a fluid coupling used in automatic transmissions that transfers power from the engine to the transmission. It contains an impeller connected to the engine, a turbine connected to the transmission, and a stator in between. In different operating modes like stall and acceleration, the torque converter can multiply torque to help vehicles start moving or can act like a fluid coupling at higher speeds. Problems that can occur include overheating, stator clutch issues, blade damage, and housing distortion from extreme operating conditions.
Single plate clutch presentation
A clutch connects and disconnects a driving shaft, such as an engine crankshaft, to a driven shaft that provides output power. A clutch uses friction between two surfaces to transmit torque from the driving shaft to the driven shaft. When the clutch pedal is pressed, springs in the pressure plate disengage the clutch plates from the flywheel, disconnecting the driven shaft. Releasing the pedal engages the clutch plates between the flywheel and pressure plate using the springs, connecting the driven shaft. A single plate clutch has one clutch plate that connects the flywheel to the driven shaft through friction to transfer power.
Homogeneous charge compression ignition hcci Engines
The document discusses Homogeneous Charge Compression Ignition (HCCI) engines. HCCI engines compress the fuel-air mixture to the point of auto-ignition, requiring no spark plug. This allows for lower emissions and improved fuel efficiency compared to traditional engines. However, auto-ignition is difficult to control precisely. Various methods are used to control the combustion timing, such as variable compression ratios or induction temperatures. HCCI engines also have a smaller adjustable power range than traditional engines. Major automakers are researching HCCI as a promising future technology.

2 fuel-supply-systems
The fuel supply system prepares fuel-air mixtures of different ratios for optimal engine performance under varying conditions. In a spark ignition engine, the carburetor mixes air and fuel outside the combustion chamber. It maintains the proper air-fuel ratio for starting, normal running, and acceleration using devices like floats, jets, and valves. In a diesel engine, only air is admitted into the combustion chamber and fuel is directly injected in spray form by the fuel injection system. Various compensation methods like extra air valves and multiple jets help the carburetor maintain the correct air-fuel ratio across different engine speeds and loads.
Basic Carburetor Design
The document discusses the basics of how a carburetor works. It mixes air and fuel for combustion in internal combustion engines. A carburetor uses Bernoulli's principle - as the speed of the air moving through the venturi increases, the pressure decreases, drawing fuel into the air stream. It has several circuits that control fuel delivery at different engine speeds and throttle positions, including an idle circuit, main circuit, power valve, and accelerator pump. Carburetors rely on a float chamber to maintain the proper fuel level and supply fuel to the carburetor. While carburetors have largely been replaced by fuel injection, they are still commonly used on small engines.

Fuel injectors ppt
Fuel injection systems have replaced carburetors to meet stricter emissions standards. There are several types of fuel injection systems. Throttle body injection uses one or two fuel injectors in the throttle body. Multi-point fuel injection uses one injector per cylinder located at each intake port for more accurate fuel delivery. Sequential fuel injection improves upon multi-point by firing each injector just before the corresponding intake valve opens for better fuel efficiency and emissions control. Modern fuel injection systems precisely control fuel delivery through electronic management of injectors and sensors to maintain optimal air-fuel ratios.

The purpose of a carburetor is to atomize fuel, mix it with air, and deliver the air-fuel mixture to the engine under different operating conditions.
Aircraft Fuel System
The fuel system is designed to provide an uninterrupted flow of clean fuel from the fuel tanks to the engine. The fuel must be available to the engine under all conditions of engine power, altitude, attitude, and during all approved flight maneuvers . Fuel systems differ greatly from aircraft to aircraft due to the relative size and complexity of the aircraft in which they are installed.
Piston Engines: Fuel
The document discusses piston engine propulsion systems, specifically focusing on carbureted fuel systems. It describes the basic components and functioning of aircraft and engine fuel systems, including fuel tanks, pumps, filters and carburetors. It provides details on how carburetors work to mix air and fuel, including the venturi, float chamber, needle valve, jets and throttle. It also discusses systems for idle, mixture control and maintaining the proper air-fuel ratio at varying conditions and altitudes.
Fuel feed system for petrol engine
The document describes the key components of a fuel feed system for a petrol engine. It includes a petrol tank, fuel lines, fuel pump, fuel filter, air cleaner, carburetor, inlet manifold, and pipelines. There are different types of fuel supply systems - gravity, pressure, vacuum, pump, and fuel injection. The gravity and pressure systems use a carburetor while fuel injection systems dispense with the carburetor and inject atomized fuel directly into the air stream using separate fuel injectors for each cylinder. The document also discusses mechanical and electrical fuel pumps as well as the purpose of fuel filters and air filters in the engine system.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
