Working of Four Stroke Engine

Question

Accepted Answer

A four-stroke engine is an internal combustion engine that completes four separate strokes in a cycle.

Intake stroke: Fuel-air mixture is drawn into the cylinder through the intake valve.
Compression stroke: The piston compresses the fuel-air mixture.
Power stroke: The spark plug ignites the compressed mixture, causing an explosion that drives the piston down.
Exhaust stroke: The piston pushes the exhaust gases out of the cylinder through the exhaust valve.

Accepted Answer

a four stroke engine is an internal combustion engine that utilises four distinct piston stroke to complete operation  in a four strok engine requires two revolution (720)Deg of the crankshaft

Accepted Answer

the pistons are connected to a rotating crankshaft through a connecting rod. Every four strokes of the piston, moving up or down the cylinder, the engine produces power through what is known as the four-stroke cycle.

Accepted Answer

Four stroke cycle engines. A four stroke cycle engine is an internal combustion engine that utilizes four dist cylinder to complete one operating distinct piston stroke (intake, compression, power, and exhaust) to complete one operating cycle. The piston make two complete passes in the cylinder to complete one operating cycle.

Accepted Answer

A four- strocke engine is a internal combustion engine in which the pistion completes four separate strokes while turning the crankshft.

A strock refer to the full travel of pistion along the cylinder,in either direction.

the four separatestrokes are termed :- intake:- also known as induction or suction

Accepted Answer

A 4-stroke engine is a very common variation of an internal combustion engine. Most modern internal combustion-powered vehicles are 4-strokes, powered by either gasoline or diesel fuel.

During engine operation, pistons go through 4 events to achieve each power cycle. The definition of an event is an up or down piston motion. Upon completion of the 4 events, the cycle is complete and ready to begin again.

4-stroke engines deliver a good balance of power, reliability and efficiency. When it comes to emissions, 4-strokes separate each event mechanically, which reduces unburned fuel emissions. It also separates oil from fuel, which significantly reduces carbon monoxide emissions. This combination of desirable traits has earned the 4-stroke the top spot in passenger vehicles today.
