Is the throttle of the gasoline engine on or off?

The gasoline engine works with the throttle on.

The function of gasoline engine throttle: the function of throttle is to change the air quantity entering the carburetor inlet, the oil pressure at the injection port and the mixture concentration. It feels difficult to start the engine in winter. Especially when you start the car in the morning, you are at a loss. In fact, it is very difficult to start in winter, mainly on carburetor engines.

Composition of gasoline engine:

Gasoline engine generally adopts reciprocating piston structure, which consists of engine body, crank-connecting rod mechanism, gas distribution system, oil supply system, lubrication system and ignition system.

Advantages of gasoline engine:

Compared with diesel engine, gasoline engine is lighter, lower in manufacturing cost, lower in noise and better in low-temperature starting performance, but lower in thermal efficiency and higher in fuel consumption.

Application of gasoline engine;

In order to be light and cheap, two-stroke air-cooled gasoline engines are widely used in low-power power machinery such as motorcycles and chainsaws.

In order to have simple structure, reliable operation and low cost, most fixed low-power gasoline engines adopt four-stroke water cooling.

Cars and light trucks mostly use overhead valve water-cooled gasoline engines, but with the increasing attention to fuel consumption, diesel engines are more and more widely used in such vehicles.

Semi-spherical combustion chamber air-cooled gasoline engine is mainly used for small aircraft to realize light weight and high power. Million car purchase subsidy
