HOW TO PETROL ENGINE WORKS

PETROL ENGINE WORKS THROUGH THE STROKES THERE ARE FOUR TYPES OF STROKES:1. INTAKE STROKE 2. COMPRESSION STROKE 3. POWER STROKE 4. EXHAUST STROKE.

STEPS OF WORKING 1. The spark plug produces a little electric spark inside the cylinder and this spark sets fire to the petrol -air mixture. 2. When the piston has been pushed to the bottom of the cylinder by the hot expending gases in the power stroke, then the exhaust Valve opens. 3. Intake valve opens and the petrol vapour and air mixture is suked Into the cylinder from the carbnrettor. 4. Gas burns and the plug starts the sparking in the cylinder 5. When the engine the piston moves down words in the cylinder 6. The piston pushes the piston rod and pushes the crank shaft. The crank shaft is joined to the wheels of a car. When the crank shaft turns, the wheels rotate and move the car. 7. The piston pushes the piston rod and the piston rod pushes the crank shaft . The crank shaft is joined to the wheels of a car. When the crank shaft turns, the wheels rotate and move the car. 8. When the crank shaft turns , the wheels rotate and move the car. 9. The piston is then forced to move upwards which compresses the fuelmixture to about one-eighth of its original volume. Higher the compression ratio, more will be the efficiency of the engine. 10. Cylinder is used to enter the fuel mixture(petrol vapour and air mixture) 11. When the sufficene amount of the fuel mixture has being entered the cylinder the intake valve gets closed
