CRD Injection & High Pressure Pump 

(Common Rail Diesel Injection & High Pressure Pump) Technologies that increase output and lower the standard of harmful emissions and the consumption of fuel of the diesel engine

The common-rail diesel dispersion device has the greatest advantage of controlling the period of dispersion, as well as greatly changing the pressure of dispersion concerning the period of prolonging dispersion.

Such advantages are possible because the pressure forming function (high pressure pump) and dispersion function (injector) operate independently from one another.
