Automotive control systems have become a driving factor in automotive innovation over the last thirty years. In order to meet the enhanced requirements for lower fuel consumption, lower exhaust emissions, improved safety as well as comfort and convenience functions, automotive control had to be applied. Nowadays the interest toward fuel consumption reduction in reciprocating internal combustion engines has achieved a key role, these concerns grew simultaneously with the interest towards drivability improvement. Drivability strongly depends on engine behavior, torque production is the direct consequence of gases expansion inside the combustion chamber as a result of fuel combustion and is not evenly distributed over a crankshaft revolution.
