What is the main power of a car engine?

The main driving force of a car engine is the gasoline in the cylinders.

The cylinder is the source of the car drive, no matter how high the speed of the car can reach, can climb a slope, can pull a heavy load, all the power comes from the inside of the cylinder.

Both are driven by fuel burned inside the cylinder to push the piston, then through the connecting rod, crankshaft, transmission, driveshaft, and finally the power is transferred to the wheels to drive the car forward.

In the cylinder, the most "suffer" is one of the piston, it is "overhead" constantly fuel combustion explosion, and "underfoot" and must be constantly "Stirring" crankshaft. The piston is the first part of the car to produce power.

The heart of the automobile engine:

If the heart of the car is the engine, then the heart of the engine is the crankshaft, the crankshaft is the engine will be converted into kinetic energy important bridge.

Subject to the centrifugal force of the rotating mass, cyclically varying gas inertial force and reciprocating inertial force **** with the role. So engine timing is calibrated around the crankshaft.

If our engine fails and we need to remove the timing chain or timing belt, then when we reinstall the belt or chain, the engine timing is "re-matched" to the engine timing.

Engine timing if not right, the light will lead to vehicle acceleration at low speeds, engine power is not smooth, fuel consumption increased phenomenon, the heavy will lead to engine piston top bad valve, resulting in engine overhaul.
