Diesel Injector Fuel Injector 095000-5332 Denso Injector for Hino, Toyota LCV, ToyotaDyna200

The good effect of the new injector on engine operation has been tested and analyzed on a single cylinder test diesel engine, and the results are compared with the piezoelectric reference injector with the same nozzle structure and close to mass production. Experimental studies confirmed that the reduction of NO and soot emissions in conflict with the objective, and compared with the benchmark injector, HiFORS injector gas emission levels were significantly improved, and showed similar combustion noise and lower HC and CO emissions.

At present, there is only the total flow test equipment of the nozzle in China, and there is no test bed for the flow detection of each nozzle orifice. Moreover, there are still more difficulties in the measurement of the flow of each nozzle orifice. In the detection aspect, the diesel nozzle detection system is generally single, only detect speed, size, pressure, total flow of some indicators, the design is relatively simple; In terms of control output, it is generally a single operation to control output of a certain indicator. With the needs of the development of motor vehicle industry, it is of great significance to develop the multi-channel detection and control equipment for each orifice flow of the nozzle, whether it is to study the structural parameters of the nozzle, the influence on the performance of diesel engine or the production and detection of the nozzle.

Diesel engine nozzle measurement and control structure

The size and uniformity of nozzle orifice flow have important influence on diesel engine performance. Domestic diesel engines mostly use four or five hole hole nozzle. The machining precision of jet hole is required to be high. It is difficult to process, and deviation is easy to occur in the production process.
