Abstract
Combustion control of a diesel engine is achieved, such that the engine has a monotonic relation between intake manifold pressure and engine torque. For a given engine speed, fuel injection parameters are primarily determined by intake manifold pressure. However, the determination of the fuel injection parameters is also secondarily based on correction factors such as oxygen concentration, intake manifold temperature, and coolant temperature. In effect, the fuel injection parameters reflect the in-cylinder gas mass.
