3.2 Feature of common rail system (CRS) engine
The fuel system of a common rail engine is completely different from that of a mechanical fuel injection pump.
Not
only does a common rail system conform to stringent emission regulation restrictions, it is feasible to multiple
highly accurate high pressure fuel injections that are not affected by engine speed.
Various parameters such as fuel pressure in the rail, intake air temperature, intake air pressure are transmitted from
various sensors to the engine ECU as a signal.
This information and command signals from the engine ECU and between various control units are communicated via
CAN communication.
The fuel system of a common rail engine is controlled by the engine ECU.
As a result fuel is injected at ideal conditions at all times suppressing the weak point of diesel engines of black smoke
when starting and when accelerating and achieves reduction of exhaust gas cleanup as well as high power output.
