A spark-ignition engine (SI engine) is an internal combustion engine, generally a petrol engine, where the combustion process of the air-fuel mixture is ignited by a spark from a spark plug. This is in contrast to compression-ignition engines, typically diesel engines, where the heat generated from compression together with the injection of fuel is enough to initiate the combustion process, without needing any external spark.
Control method for a spark-ignition engine running on gasoline and ethanol
On the basis of determining the first ethanol ratio value (RATE) obtained with a positive or negative uncertainty of x%, a corrected ratio value (RATEcorr) is determined by subtracting x% from the first value (RATE), and for each point in the zone, the concentration set point on the thermal protection zone is adjusted to a value corresponding to the corrected ratio.
