Function of the front elbow of throttle valve of Wei Chai natural gas engine

Wei Chai's natural gas engines are: CNG and LNG engines are basically unchanged.

The main natural gas engines in Wei Chai are WP5, WP6, WP7, WP 10, WP 12, etc. The power coverage is 160-480 horsepower. No matter light trucks, medium trucks or heavy trucks, they can get the best match. At present, Wei Chai natural gas engines WP5, WP6 and WP7 are widely used in passenger cars, while WP 10 and WP 12 are mainly equipped in heavy trucks and special vehicles.

Natural gas engines are mainly divided into LNG (liquefied natural gas) and CNG (compressed natural gas). Wei Chai natural gas engine is mainly designed and developed on the basis of the original diesel engine, and its reliability has been effectively guaranteed. American Wood OH2.0 gas electric control system is adopted, with single-point injection and closed-loop control of lean combustion. Add a brand-new gas supply system to replace the original diesel fuel system; And the ignition combustion mode is adopted, and the ignition control system is added, which is more in line with the combustion mode of the gas system; In order to prevent knocking, the compression ratio of gas engine is smaller than that of diesel engine, and the form of combustion chamber is also different from that of diesel engine. A signal generator is added to judge the cylinder and measure the engine speed. In addition, a mixer and a throttle valve are added to mix gas and air in the mixer; Due to the high exhaust temperature, the supercharger usually adopts a water-cooled intermediate shell, the intake and exhaust valve seats are mainly made of wear-resistant and high-temperature resistant materials, and the exhaust pipe is made of heat insulation materials.
