Abstract:Given modern increased ability to model, measure and process the operation conditions of the internal combustion engine, an opportunity was presented to greatly improve the performance of older combustion engines through the development of a more affordable engine management system. As part of the development of this system, a study into the possible improvements to the usage of common automotive drive train sensors was conducted, resulting in a numerical model of the common SI (Spark Ignition) engine, the development of a real time measurement system and a set of real-time measurements on a representative Volvo b230k engine. These real time measurements were combined with the created model to result in the finding of 3 additional uses for the common MAP (Manifold Air Pressure) sensor, namely engine speed determination, crank angle position read out and camshaft profile identification. Additionally, methodologies for the usage of EGT (Exhaust Gas Temperature) sensors for the determination of the AFR (Air Fuel ratio) with provided engine speed were proposed, and the possible relationship between MAT (Manifold Air Temperature) and engine operating friction were discussed.
