Development of next generation common rail fuel injection system is still running. The latest version is currently still using a mechanical regulator. But unlike the previous ones.

There are a variety of regulators that can be used for next generation common rail fuel injection system. There are a variety of regulators that can be used, of course with different results as well. Better performance and not complicated! Of course this is what we expected. But sometimes we just get it after all this time we tried.

Development of next generation common rail fuel injection system is still running. Latest version to the current use of mechanical fuel regulator.

Fuel injection system, including the next generation common rail fuel injection system, fuel regulator could use electronic or mechanical. Electronic or mechanical regulators, each of which has advantages and disadvantages. Mechanical regulators have advantages more a simple ECU program. The drawback, when viewed from the mechanical side will look more complicated.

Design of a next generation common rail fuel injection system our design, is the development of a common rail fuel injection system that exist now. Therefore most components such as components in the common rail fuel injection system that already exist today.

The difference with the common rail fuel injection system that now exist, that the next generation common rail fuel injection system design that we have the addition of pressure sensors, pressure relief valve position settings, and the addition of simple components that we can not mention here.

It seems we have quite a long time designing the next generation common rail fuel injection system design, and try to market. Our market is not only through this website. We also offer design it to companies we think are willing to buy. But it unsuccessful. Maybe they do not want to take risks that are too large. Seems to have known, if buying creative design has no small risk, especially for complex designs.

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 issue on 50 micrometers on injector orifice, we get from the paper by J.B. Woodford and G.R. Fanske of Argone National Laboratory under the title the fabrication of small-orifice fuel injectors.

The paper entitles the fabrication of small-orifice fuel injectors also discusses the benefits of injector with orifice diameter 50 micrometers. Particular matter is eliminated by reducing the orifice diameter up to 50 micrometers. For us, as a designer, this is a challenge. With 50 micrometers in diameter, orifice will be sensitive to the blockage (clogging).

Can the next generation common rail fuel injection system really be applied in 50 micrometer-diameter orifice and bio-diesel fuel? To answer this question, we will not lead you to “yes” or “no” answer. Rather, we will explain various factors related to this problem.

Several years ago, we have started to design the next generation common rail fuel injection system for diesel engine. Exactly, when diesel-based car using common rail fuel injection system is started to be marketed in Indonesia.

The common rail fuel injection system in diesel car potentially make diesel engine is more environmental-friendly and comfortable to that using jerk-fuel injection system. However, in addition to such an excellence, the common rail fuel injection system needs better quality of fuel. In Indonesia, better diesel fuel has not available in many places yet.

The common rail fuel injection system in diesel engine is a system that enables diesel engine to run more eco-friendly than other types of fuel injection systems. However, it is not enough. Engineers has still put their efforts to make the much more eco-friendly system. One of them is by minimizing orifice diameter. Consequently, the orifice will be easily clogged. To avoid such a clogging caused by some solid particles, we may use better filter.
