on the intake stoke, the piston is going down to the bottom of the cylinder. As it is going down the intake valve opens and allows a mixture of air and gas in the chamber.
the piston ,once it reaches the bottom of the cylinder,it starts to travel upward(this is the start of the compression stroke) and compresses the air/fuel mixture,and at the same time the intake velve closes,craeting a sealed chamber. As the piston continues to go up it keeps squeezing the air and fuel and just before it tops out the spark-plug fires,igniting this mixture which drives the piston down,starting the power stroke.

What else can I help you with?
How many compression strokes during a compression test?
3 - 4 per cylinder.
In a car with fuel injection during which stroke does fuel enter the cylinders?
Number 1, the intake stroke. Weather it is fuel injected or has a carburetor makes no difference. Most internal combustion engines today are 4 stroke engines. The four strokes refer to intake, compression, combustion and exhaust strokes that occur during two crankshaft rotations per working cycle of Otto Cycle and Diesel engines. The four steps in this cycle are often informally referred to as "suck, squeeze (or squash), bang, blow." Intake stroke
Compression happens during which part of the sound wave?
Compression happens during the part of the sound wave where the air particles are pushed closer together, resulting in an increase in air pressure. This creates a region of higher pressure within the sound wave, causing the compression of the air particles.
What is the 4-1 process in otto cycle?
The four strokes refer to intake, compression, combustion and exhaust strokes that occur during two crankshaft rotations per working cycle of Otto Cycle.
What happens to volume of liquid during compression?
The volume of a liquid responds poorly to compression, but might decrease slightly.
What are the four strokes to a four stroke engine?
The four strokes of a four-stroke engine are the intake, compression, power, and exhaust strokes. During the intake stroke, the engine draws in air and fuel. The compression stroke then compresses this mixture, followed by the power stroke, where the spark plug ignites the mixture, generating power. Finally, in the exhaust stroke, the engine expels the burnt gases from the combustion process.
Strokes produces mechanical energy output from a four cycle engine?
In a four-cycle engine, strokes refer to the four movements of the piston during the combustion process: intake, compression, power, and exhaust. These strokes work together to convert fuel into mechanical energy that powers the vehicle or machinery.
What are the four strokes of a internal combustion engine?
The four strokes of an internal combustion engine are intake, compression, power, and exhaust. During the intake stroke, air and fuel are drawn into the combustion chamber. In the compression stroke, the mixture is compressed. The power stroke is when the compressed mixture is ignited to create power, while the exhaust stroke expels the burned gases from the chamber.
What is the position of the valves during the compression stroke?
During the compression stroke, both the intake and exhaust valves are closed. This sealing allows the piston to compress the air-fuel mixture (in gasoline engines) or air (in diesel engines) within the cylinder, increasing the pressure and temperature before ignition. The closed valves ensure that no gases escape and that the compression is efficient, setting the stage for a powerful combustion event in the subsequent power stroke.
What are the four strokes of an engine in proper order?
The four strokes of an engine, in proper order, are: intake, compression, power, and exhaust. During the intake stroke, the engine draws in air and fuel. Next, the compression stroke compresses the mixture, followed by the power stroke where the mixture is ignited, creating power. Finally, the exhaust stroke expels the spent gases from the combustion process.
What is swirl in diesel engines?
Swirl in diesel engines refers to the rotational motion of air within the combustion chamber during the intake and compression strokes. This swirling motion enhances the mixing of fuel and air, leading to more efficient combustion and improved performance. By promoting better atomization of the fuel and a more uniform temperature distribution, swirl helps to reduce emissions and increase engine efficiency. The design of the combustion chamber and intake ports can significantly influence the swirl characteristics in diesel engines.
What happens during the compression stroke in an internal combustion engine?
During the compression stroke in an internal combustion engine, the piston moves upward, compressing the air-fuel mixture in the combustion chamber. This compression increases the pressure and temperature of the mixture, preparing it for ignition.
