METHOD AND DEVICE FOR DETECTING GLOW IGNITION OF AN INTERNAL COMBUSTION ENGINE IN A MOTOR VEHICLE

摘要

A method for detecting glow ignition of a fuel-air mixture in a combustion chamber of an internal combustion engine having at least one first cylinder and at least one second cylinder, said at least one first and second cylinders being connected by a crankshaft, according to which method partial segment times of the at least one first cylinder are measured. The method is characterized in that partial segment times of the at least one second cylinder are measured and a reference characteristic for the glow ignition is formed by a comparison of partial segment times of the at least one first cylinder with partial segment times of the at least one second cylinder and subsequently a signal is generated for the detection of the glow ignition on the basis of the comparison.

1. A method for detecting a glow ignition of a fuel-air mixture in a cylinder chamber of an internal combustion engine having control unit, at least one first cylinder and at least one second cylinder, said at least one first and second cylinders being connected to a crankshaft, said method comprising the steps of:
measuring, via the control unit, subsegment times of the at least one first cylinder, measuring, via the control unit, subsegment times of the at least one second cylinder; comparing, via the control unit, the subsegment times of the at least one first cylinder to the subsegment times of the at least one second cylinder thereby forming a reference characteristic for the glow ignition, and subsequently generating, via the control unit, a signal as a function of the comparison, said signal corresponding to the detection of the glow ignition.
