<p>#CMT# #/CMT# The method involves adjusting combustion parameter based on an optimal preset value to reduce pollutant emissions, when a combustion engine is supplied with low alcoholized fuel. The parameter is adjusted based on another optimal preset value to reduce the pollutant emissions, when the engine is supplied with fuel having high alcohol rate, e.g. E85 fuel, if difference between a measured value of speed of the engine and a predicted value of the engine speed is higher than a preset threshold after N iterations of the parameter adjustment carried out based on the former optimal value. #CMT# : #/CMT# Independent claims are also included for the following: (1) an information recording medium comprising a set of instructions for implementing a method for adjusting combustion parameter of a combustion engine (2) a device for adjusting combustion parameter of a combustion engine during cold starting. #CMT#USE : #/CMT# Method for adjusting a combustion parameter of a combustion engine of a vehicle (claimed) such as motor vehicle e.g. car, during cold starting of the engine, to modify quantity of fuel/oxidant injected in a cylinder of the engine, modify moment of intake or exhaust of gas in the cylinder or to modify moment of ignition of a gaseous mixture in the cylinder. #CMT#ADVANTAGE : #/CMT# The method can correctly adjust the combustion parameter of the engine during cold starting of the engine, when the engine is supplied with low alcoholized fuel and fuel having high alcohol rate, thus correctly operating the engine even if the fuel has high alcohol rate. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a flowchart illustrating a method for adjusting a combustion parameter of a combustion engine of a vehicle.</p> |
