METHOD AND APPARATUS FOR CONTROLLING A DUAL FUEL COMPRESSION IGNITION ENGINE

摘要

A compression ignition internal combustion engine has combustion sensors for detecting combustion of fuel in the cylinders, and at least one electronic control unit receiving signals from the combustion sensors. A fuel mixing unit is connected with at least a first source of a first fuel and a second source of a fuel conditioner. Based on a detected start of ignition of fuel in the individual cylinder compared with start of fuel injection in said cylinder, the at least one electronic control unit controls the mixing ratio of the first fuel and the fuel conditioner in the fuel mixture delivered by the mixing unit to the fuel injectors, so that the ignitability of the fuel mixture is decreased when the ignition delay is at a predetermined value for ignition delay.
