What is the difference between a 6-cylinder car and a 4-cylinder car?

[VanLilah]

The difference between a 6-cylinder car and a 4-cylinder car lies in the number of engine cylinders: a 6-cylinder engine has 6 cylinders, while a 4-cylinder engine has 4 cylinders. The working principles of 6-cylinder and 4-cylinder engines are as follows: 1. Compression stroke: The piston moves from the bottom dead center to the top dead center, with both intake and exhaust valves closed; 2. Intake stroke: The piston is driven by the crankshaft from the top dead center to the bottom dead center, while the intake valve opens and the exhaust valve closes; 3. Exhaust stroke: The exhaust valve opens, and the piston moves from the bottom dead center to the top dead center, expelling exhaust gases as the piston rises; 4. Combustion and expansion stroke: Both intake and exhaust valves close simultaneously, the spark plug ignites, and the air-fuel mixture burns vigorously.
