Engine Calibration of Fuel Quality Adaptation Function with Intake Manifold Temperature Sensor
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 12
Abstract
Today different fuel qualities are taken into consideration at pre-injection and start-injection fuel mass. The nominal fuel mass with reference fuel to guarantee engine stability with minimum emissions, has to be increased to compensate low evaporation fuel. This paper presents engine calibration of fuel quality adaptation function(FQA) with intake manifold temperature sensor. In engine test benches, the first step is to investigate the temperature behavior in the intake manifold depending on fuels and the driving cycle, the load condition and the boundary conditions as engine rpm, MAF(Mass Air Flow), MAP(Manifold Absolute Pressure), TIA(Intake Air Temperature), TCO(Coolant Temperature). The further step is to investigate the possibility to detect a changing fuel quality in running after fill up the tank.
