Method to minimize the production of nitrogen oxide in air compressing supercharged combustion engines.

摘要

The start of the fuel injection is set according to the air temp. Where the air temp. is below normal levels, the injection start is advanced and, as the air temp. rises, the injection is retarded. An electronic control is used in the correction field to regulate and control the fuel injection start over the engine revolution and/or load. The injection start (SB) is corrected at least in one region of 0 - 30 % of the maximum engine torque over the air temp. (t) according to the following equation: SB = SBO + 0.2(t-tO) where the index O is normal conditions at 25 deg. C.
