Fuel injection system for internal combustion engine detects presence or absence of auxiliary injection by comparing detected physical value with related reference value

摘要

The system has a fuel injection device, a device for (passing a control parameter to the injection device instructing it to perform main and auxiliary injections during a cycle of the engine, a detector of a physical value produced by the fuel injection. and an injection detector for detecting a reference level based on the physical value and for detecting the presence or absence of an auxiliary injection by comparing the physical value with the reference value.
