The document discusses the concept and working of a six-stroke internal combustion engine. A six-stroke engine generates power twice per cycle by adding two additional strokes to the traditional four-stroke cycle. This results in higher efficiency and lower fuel consumption compared to four-stroke engines. The six-stroke cycle includes intake, compression, power, exhaust, and two additional strokes where heated air is used to generate a second power stroke. Major inventors who developed six-stroke engines include Malcolm Beare, Bruce Crower, and Velozeta. The advantages are increased efficiency and reduced emissions, but disadvantages include increased complexity and cost.

A six-stroke engine provides two power strokes in each cycle, improving efficiency over a traditional four-stroke engine. It works by using the heat from the exhaust stroke to generate a secondary expansion and power stroke. The first four strokes are identical to a four-stroke engine. In the fifth stroke, water is injected into the hot combustion chamber and turns to steam, expanding to drive the piston down for a second power stroke. This recovers waste heat from the exhaust to improve fuel efficiency over a four-stroke engine by up to 30-40%. However, additional systems are required to inject water and utilize the secondary expansion, increasing complexity over a traditional design.
REVIEW SIX STROKE ENGINE
Now a day the most difficult challenges in engine technology is to increase its thermal efficiency, If the efficiency is higher, than there will less fuel consumption and lower atmospheric emissions per unit of work produced by the engine. In Six Stroke engine, the name indicates a cycle of six strokes in which two are useful power strokes. The engine which we get by adding two more stroke in existing four stroke engines generates more power with higher fuel efficiency. The exhausted heat generated form four stroke cycle is used in this engine to get an additional power and exhaust stroke of the piston in the same cylinder. In this engine, steam is produce from water with the help of heat generated from four-stroke cycle, which is later used as a working fluid for the additional power stroke. This steam will force the piston down. As well as extracting power, the additional stroke cools the engine by water which is used for steam generation and removes the need for a cooling system which is used in four stroke Otto cycle and makes the engine lighter and giving 40% increased efficiency over the normal Otto cycle. In six stroke engine. The pistons go up and down six times for each injection of fuel. These six stroke engines have two power strokes: one by fuel, one by steam
combustion and its effects
The internal combustion engine uses combustion of fuel to power pistons or turbines and convert the energy to mechanical motion. There are several types of internal combustion engines including gasoline, diesel, gas turbine, jet, and Wankel rotary engines. They all work on the principle of combusting fuel but differ in ignition methods and fuel used. Hydrogen may eventually replace fossil fuels in traditional internal combustion engines or fuel cells could replace them altogether.

This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

- 5. The brief history of internal combustion engines. What is an internal combustion engine? Why do we need them in today’s world? What do we use them for? How do they work? A brief discussion on diesel engines.
- 7. Many designs have been made over the last 4 centuries but only a few men were recognized as inventors. The first person to invent a working internal combustion engine automobile was Francois Isaac de Rivaz of Switzerland in 1807. Mixing hydrogen and oxygen for fuel. The first gasoline powered engine was built in 1864 by a man named Siegfried Marcus and was said to be the forerunner to the modern automobile. It reached speeds up to ten mph. In 1876 two of the greatest engines were invented. The two and four stroke engine by Nikolaus August Otto and Sir Dougald clerk. Starting the rise of even better and more efficient machine.
- 10. Spark plug Piston Piston rings Intake valve Crankshaft Cylinder Piston rod Exhaust valve
- 12. The internal combustion of an engine is considered to be the heart of the automobile. They are defined as any engine that uses an explosive combustion of fuel and air to push a piston within a cylinder. Forming the repeating cycle known as the strokes. Intake, Compression, Power Stroke, and Exhaust are the four actions of one stroke. The difference between the two cycle and four cycle engine is the number of strokes it uses to start the fuel reaction of internal combustion. Diesel engines unlike gasoline do not need spark plugs to ignite the fuel. Instead it uses compression but undergoes the same principle of a stroke.
- 14. This starts at the highest point known as top dead center and ends at bottom dead center The intake stroke allows the piston to suck fuel and air into the combustion chamber through the intake valve port.
- 16. Compression starts at bottom dead center and ends at top dead center. The second motion of the stroke takes all the fuel and air that was stored and compresses it into one tenth its original sizes. Making the air/fuel mixture increase in temperature preparing it for the next stage in its combustion cycle.
- 18. The power stroke starts as soon as the piston reaches top dead center allowing the spark plug to ignite. This electric current created by the spark plug ignites the fuel and air mixture sending the piston back down the cylinder with a pressure reaching high as 600 PSI.
- 20. The final stage of the stroke releases all the burned fuel through the exhaust valve. As the piston moves from bottom dead center to top dead center it takes all the burned fuel and pushes it out of the cylinder, preparing it for the next cycle of strokes.
- 21. Drawing
- 24. Diesel engines work on the same principle as the two and four stroke engines. They do not need a spark plug to ignite the fuel. During the intake stroke, air does not mixed with the fuel in the cylinder. Instead as the air reaches high enough compression Fuel is then sprayed into the cylinder creating ignition. This pushes the piston down the cylinder at a pressure of 500 PSI, starting the stroke all over again.
- 25. Internal combustion engines have ultimately revolutionized the way we live. With the small and light weight design of the two cycle engine tasks like trimming the hedges and cutting down weeds became easier and more efficient. With the power of the four stroke we are now able to dig up dirt and cut down trees with out even breaking a sweat. Internal combustion engines have made life easier since the first one was built in the early 1800’s .
