Abstract
The invention relates to a method for operating an internal combustion engine, wherein air is inducted and then compressed. Before introduction into a combustion chamber of the internal combustion engine, the air humidity of the inducted air is determined and temperature of the compressed air introduced into the combustion chamber is altered depending on the air humidity of the inducted air.
Claims20
A method of operating an internal combustion engine, comprising:
- inducting air into an induction tract and determining an air humidity of the inducted air before compression of the inducted air;
- mixing the inducted air with fuel to obtain an air-and-fuel mixture;
- compressing the air-and-fuel mixture before feeding the air-and-fuel mixture to a combustion chamber of the internal combustion engine;
- and
- controlling a temperature of the compressed air-and-fuel mixture based on the air humidity of the inducted air.
2 more elements
An internal combustion engine comprising:
- a humidity sensor for measuring air humidity of air inducted into an induction tract of the internal combustion engine, said humidity sensor being located so as to measure the air humidity before compression of the inducted air;
- a gas mixing device for mixing fuel and the inducted air to form an air-and-fuel mixture;
- a compressor device downstream of said gas mixing device for compressing the air-and-fuel mixture;
- a temperature-adjusting device for altering a temperature of the compressed air-and-fuel mixture;
- and
- a control device for regulating the internal combustion engine to a substantially constant operating parameter by controlling said temperature-adjusting device based on the air humidity of the inducted air as measured by said humidity sensor.
