This paper proposes a set-point adaptation algorithm for combustion control to reduce transient NOx emissions. The set-point adaptation algorithm is activated only when an NOx emission spike is detected. For the detection of NOx emission spikes, an e

A closed-loop control for torque balance using a cylinder pressure sensor can improve drivability and can suppress noise from light-duty diesel engines. However, the closed-loop control requires cylinder pressure sensor cost and computational time ab

This paper presents an integration method of AUTOSAR-compliant ECUs which can evaluate resource constraints in an early-stage of development. There are three types of resources for an ECU (timing, memory, and interface) which should be carefully mana

Although injection timing does not change at every cycle in compression ignition engines, the variations in combustion phase may occur. The variations in combustion phase are directly related to emission dispersion, torque variation, and fuel economy

In production-type engine control systems for passenger car diesel engines, the mass air flow is commonly used as a feedback variable for control of the exhaust gas recirculation system. However, the mass air flow is not appropriate as a feedback var
