The next generation common rail fuel injection system we have designed can be applied on injector with the orifice diameter of 50 micrometers and biodiesel. This, of course, has not undergone any laboratory test since the injection system is still under design work. The success, however, can be logically explained.

The injector with quite smaller diameter of orifice, i.e. 50 micrometers, is certainly easily clogged. Two types of clogging possibly occur due to solid particles that the fuel carries and the motion-caused clogging of the fuel.

The solid particle-caused clogging can be prevented through the use of good filter. But, the method cannot be applied in fuel motion-caused clogging. This kind of clogging slowly occur. The aperture previously larger is getting to be gradually narrowed due to crust coating.

Our design of the next generation common rail fuel injection system is supplemented with volumetric stability as available in the jerk fuel injection systems. It is adjustable with the condition of orifice. The fuel pressure can increase or reduce based on the orifice condition; hence, the volume of fuel injected into the combustion chamber will be in stable condition from time to time.
