How does a petrol engine works?
How does a petrol engine works? The engine consists of a fixed cylinder and a moving piston. The expanding combustion gases push the piston, which in turn rotates the crankshaft. After the piston compresses the fuel-air mixture, the spark ignites it, causing combustion. The expansion of the combustion gases pushes the piston during the power stroke. How does a modern petrol engine work? In today's most modern engines, gasoline is injected directly into the cylinders near the top of the compression stroke. (Other engines premix the air and fuel during the intake stroke.) The resulting expansion of hot, burning gases...
