The four-stroke cycle is the foundation of the engine. The first stroke is the intake stroke which the intake valve opens and the air and gas mixture enter the combustion chamber. The second stroke is the compression stroke and when that occurs the piston heads towards the bottom of the cylinder and then starts to rise to the top. The third stroke is the power stroke and as the piston rises to the top it goes to the highest possible point in the cylinder and when it is at that point the gas and air mixture is compressed and at that precise moment the spark plug administers a spark which the...
