Idle speed adjustment method of six-cylinder engine

Start the engine to warm up for 5 ~ 10 min, then turn the throttle to the end, pull off the protective cap on the carburetor, and adjust the stop nut of the throttle control cable sheath, so that there is a free stroke of 2 ~ 3 mm between the throttle control cable sheath and the stop nut, and the throttle can be lifted freely at the lowest position.

If the idle speed of a two-cylinder engine is adjusted, the spark plug cap on one cylinder must be removed first. Because the engine is working, the spark plug cap must be grounded immediately, that is, put on the cylinder radiator (the mouth of the spark plug cap faces the cylinder radiator), otherwise the high-voltage charge of the ignition system will suddenly increase, which may cause an accident in the circuit (it is not necessary to remove the spark plug cap for a single-cylinder engine).

Precautions for 6-cylinder engine

In terms of power, the six-cylinder car has two more cylinders to do work than the four-cylinder car, so the power output provided by the cylinders is much higher than that of the four-cylinder car, so the acceleration effect and the highest driving speed of the six-cylinder car are better than that of the four-cylinder car.

In terms of fuel consumption, because the six-cylinder engine provides more power output and consumes more fuel at work, the four-cylinder engine is better than the six-cylinder engine in terms of fuel economy
