What is the firing order of a four-cylinder engine?

[DiEva]

The firing order of a four-cylinder engine can be either 1-2-4-3 or 1-3-4-2, depending on factors such as the crankshaft structure. Here is some relevant information: 1. Working cycle: The working cycle of a four-stroke gasoline engine consists of four piston strokes, namely the intake stroke, compression stroke, power stroke, and exhaust stroke. Currently, all internal combustion engines used are four-stroke engines. The four strokes refer to one working cycle, where the piston moves up and down four times to complete the intake, compression, power, and exhaust processes. 2. Crankshaft: The crankshaft is an important component in a car engine. Its function is to convert the gas force transmitted by the piston and connecting rod into torque, transforming the linear motion of the piston into rotational motion, which is used to drive the car's transmission system, the engine's valve train, and other auxiliary devices.
