The Comrail™ HPCR Fuel System, How does it Work?

The common-rail injection of fuel at a super high pressure is achieved by adopting a common-rail pressure accumulator forward of the injectors. Fuel injection at 10-20,000 PSI begins to provide combustion optimization due to better oxygenation of the fuel during the burning process.

A better burn means better combustion efficiency and a reduction in PM and black smoke emissions. Normally, fuel is injected during the compression stroke of most engines and the injection occurs only once per cycle.

With Comrail™, an electronic control system enables multiple pulse injections of fuel in one-1000th of a second during the compression stroke, which allows for more precise control of the fuel delivery, resulting in a more efficient combustion cycle. Better combustion results in a reduction in NOx emissions.
