Wuxi Weifu specializes in the production of precision fuel nozzle assemblies, which are widely used in low, medium and high-power diesel engines across automotive, engineering, military and other sectors, with a product portfolio covering over 1,070 SKUs. Currently, our fuel nozzle product line is divided into two main categories: mechanical hole-type fuel nozzles and electronic control fuel nozzles. Mechanical nozzles are further segmented into the P-series and S-series. A fuel nozzle is a precision mated pair consisting of a needle valve and a nozzle body. Its basic working principle is as follows: high-pressure fuel enters the chamber through the inlet port of the nozzle body. The needle valve then opens, and the fuel is injected at high speed through the micro-orifices at the nozzle tip to form a fine mist, ensuring complete combustion within the engine cylinder.
