METHOD FOR RECOGNISING IRREGULAR COMBUSTION PROCESSES IN AN INTERNAL COMBUSTION ENGINE |
摘要 |
The aim of the present invention, independently of the assumption that a pre-ignition/auto-ignition generates similar high-frequency pressure vibrations in the combustion chamber, such as a knocking combustion, and independently of a consideration of the rate of rotation of the crankshaft, is to ensure recognition of every pre-ignition/auto-ignition. According to the invention a method is proposed for recognising irregular combustion in an internal combustion engine, wherein the internal combustion engine comprises an injector, wherein by means of the injector fuel is supplied directly to the combustion chamber of a cylinder of the internal combustion engine, wherein the injector is connected to a fuel supply line, wherein the fuel supply line comprises a pressure sensor for measuring the pressure in the fuel supply line, wherein depending upon the measured pressure prevailing during supply of fuel into the combustion chamber in the fuel supply line it is ascertained whether or not irregular combustion is occurring. |
