3. 4. The process of filling the cylinder with the proper air-fuel mixture through the intake valve. Compression- The process of compressing the air-fuel mixture in the cylinder to make it more combustible. Combustion-the process of igniting the compressed air-fuel mixture to create motion and the overall power of the engine.
Four-stroke engine
Four-stroke cycle used in gasoline/petrol engines: intake (1), compression (2), power (3), and exhaust (4). The right blue side is the intake port and the left brown side is the exhaust port. The cylinder wall is a thin sleeve surrounding the piston head which creates a space for the combustion of fuel and the genesis of mechanical energy.

What is a 4-Stroke Engine?
A four-stroke engine completes a power cycle after the completion of two revolutions of the crankshaft or 4 strokes of the piston. The 4-stroke engines are most commonly used in motorcycles, automobiles, and other vehicles, as well as in generators and other machinery. These engines are famous because of their high reliability and efficiency.
Four stroke engine
The four-stroke engine is the most common types of internal combustion engines and is used in various automobiles (that specifically use gasoline as fuel) like cars, trucks, and some motorbikes (many motorbikes use a two stroke engine).A four stroke engine delivers one power stroke for every two cycles of the piston (or four piston strokes). There is an animation to the right (Figure 1) of a ...
Four Stroke Engine
A 4-stroke engine is quieter than a 2-stroke engine. 2-stroke engines tend to wear out fast because they are designed to run at a higher RPM. 2-stroke engines are easier to fix because of their simple construction. 4-stroke engines have complex designs with more parts, making them more expensive, and repairs cost more.
Animated Engines
The four stroke engine is probably the most common engine type nowadays. It powers almost all cars and trucks. Speed 10 fps. The four strokes of the cycle are intake, compression, power, and exhaust. Each corresponds to one full stroke of the piston; therefore, the complete cycle requires two revolutions of the crankshaft to complete.
The Four Stroke Engine Cycle
The Four Stroke Cycle. As long as the engine is running, it will continue to repeat the four steps in a four-stroke cycle continuously. Each step in the cycle represents a 180° movement of the piston which corresponds to a half-revolution of the crankshaft. Since it takes two crankshaft revolutions to complete one four-stroke cycle, the ...

Ic Engine PPT 4 Stroke
The document summarizes the four-stroke engine cycle. It explains that in a four-stroke cycle, the crankshaft revolves 360 degrees to complete the cycle, consisting of the intake, compression, power, and exhaust strokes. During each stroke, the piston moves between top and bottom dead centers as the valves open and close to intake air and fuel and exhaust gases at the proper times. Valve ...

4 Stroke Engine cycle. Engine displacement • A cylinders displacement is the volume of the cylinder when the piston is at BDC. • It is the sum of the displacement of each cylinder. • It is defined as the volume of air/fuel mixture an engine can draw in. Engine displacement Ex: 700 cc (cubic centimetres) 1000 cc = 1 Litre.
