METHOD FOR CONTROLLING AND REGULATING AN INTERNAL COMBUSTION ENGINE ACCORDING TO THE HCCI COMBUSTION METHOD

摘要

A method is proposed for controlling and regulating an internal combustion engine according to the HCCI combustion method, in which a first fuel in a basic mixture is ignited using a pilot fuel, and in which the fuel quantities of the first fuel and the pilot fuel are changed to represent an operating point of the internal combustion engine. The invention is characterized in that a target combustion energy (VE(SL)) is calculated as a function of a power demand and, based on the target combustion energy (VE(SL)), the fuel quantity of the first fuel and the fuel quantity of the pilot fuel are determined using a distribution factor (CHI), wherein the distribution factor (CHI) is calculated as a function of an actual combustion position (VL(IST)) to a target combustion position (VL(SL)) using a combustion position controller (18).

1. Method for controlling and regulating an internal combustion engine configured to operate according to a Homogeneous Compression Charge Ignition (HCCI) combustion cycle, in which a first fuel in a basic mixture is ignited using a pilot fuel, and in which respective initial quantities of the first fuel and the pilot fuel are changed to represent an operating point of the internal combustion engine, comprising:
determining a target combustion energy as a function of a power demand, determining a subsequent first fuel quantity of the first fuel and a subsequent pilot fuel quantity of the pilot fuel based at least upon the target combustion energy, using a distribution factor, wherein the distribution factor is calculated as a function of an actual combustion position in relation to a target combustion position using a combustion position controller; and changing the operating point of the internal combustion engine from the respective initial quantities of the first fuel and the pilot fuel to the respective subsequent quantities of the first fuel and the pilot fuel.
