Emission regulations and fuel economy regulations are becoming more severe simultaneously, and they give much issue for automotive diesel R&D society. Moreover, emission test cycles are getting more tough transient conditions, like as WLTP. To meet the emission regulations in this trend, in-cylinder combustion requires more precise control. Designing hardware robustly and improving controllable are possible solutions to accomplish the precise combustion control. On the other hand, combustion control based on in-cylinder pressure signal is helpful to control in-cylinder combustion directly. Combustion control using in-cylinder pressure signal is also known to be useful to reducing engine-by-engine exhaust emissions variation due to the manufacturing tolerance, variation of fuel specification and deterioration of engine component during the whole lifetime.
