FOUR STROKE PETROL ENGINE The four stroke petrol engine works in the following way:- Intake stroke In this stroke‚ fuel and air is allowed inside the cylinder by the downward movement of the piston which involves the opening of intake valve. Compression stroke Piston moves upward again in this stroke and the fuel and air mixture is compressed. Power stroke In this stroke power is generated when the spark plug ignites the fuel and piston moves down‚ this helps the engine to start initially

COMPONENTS OF INTERNAL COMBUSTION ENGINE Even though reciprocating internal combustion engines look quite sim¬ple‚ they are highly complex machines. There are hundreds of compo¬nents which have to perform their functions satisfactorily to produce out¬put power. The main components of the IC engine and their functions are described below. • Cylinder Block: The cylinder block is the main supporting structure for the various components. The cylinder of a multi-cylinder engine is cast as a single unit

Description of the Operation of a Turbofan Engine Agiapal Sandhu Engl 100 November 12‚ 2014 Introduction A turbofan engine is found on all commercial airliners around the globe. The turbofan engine works by way of a thermodynamic cycle where air is taken into the engine‚ then compressed‚ combusted‚ expanded‚ and finally exhausted out of the engine. This creates thrust in the engine and causes the vehicle to propel forward

Used for the Engine Block The engine is the single most important part of the automobile. Without it‚ the car simply will not move. It is important that the cylinder or engine block is built to withstand the high temperatures and pressures that are put into it and it is equally important that the engine block is built to last. Over the years‚ materials used for making engine blocks have changed and materials sciences have matured enough to find the best possible materials to build engine blocks. Common

The Steam Engine and its Inventors The invention and modernization of the steam engine which was one of the most important technologies in the Industrial Revolution. Without the steam engine‚ humanity would most likely still be in pre-industrial times without our current technology. Despite this‚ the first generation of steam engines were not very effective. Thomas Savery was the first person to invent a steam engine used to pump water out of mines.1 Thomas Savery’s engine was very impractical and

SIX-STROKE ENGINE INTRODUCTION: 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. However
