One of the most important factors affecting fuel efficiency and emissions of automotive
engines is combustion quality that is usually controlled by managing spark advance (SA) in …

A widespread consensus among internal combustion engine researchers is that higher
thermal efficiency can be achieved with lean combustion. However, compared with a normal …

Cycle-to-cycle feedback control is employed to achieve optimal combustion phasing while
maintaining high levels of exhaust gas recirculation by adjusting the spark advance and the …

A control-oriented model of spark ignition combustion is presented. The model makes use of
avaliable signals, such as spark advance, air mass, intake pressure, and lambda, to …

In recent years, as engine control strategies have grown increasingly sophisticated in a
continued drive for increasing efficiency and reducing emissions, engine operation has …

Dilute combustion using exhaust gas recirculation (EGR) presents a cost-effective method
for increasing the efficiency of spark-ignition (SI) engines. However, the maximum amount of …

This paper presents an in-cylinder pressure measurement system for cycle-to-cycle
feedback combustion control purposes. Such a system uses off-the-shelf components to …

For energy-assisted compression ignition (EACI) engine propulsion at high-altitude
operating conditions using sustainable jet fuels with varying cetane numbers, it is essential …

In spark-ignited (SI) engines, the spark advance (SA) controls the combustion phase that
has a significant impact on the efficiency. Online self-optimizing control (SOC) of SA to …

This paper proposes a two-stage hierarchy control system with model predictive control
(MPC) for connected parallel HEVs with available traffic information. In the first stage, a …
