Abstract During the highly transient process of the direct-start in a four-cylinder GDI engine, each cylinder exhibits specific characteristics in terms of in-cylinder conditions and energy demands, necessitating different control for each cylinder. However, recent studies have paid insufficient attention to cylinders other than the first starting cylinder. This paper proposes a comprehensive control strategy based on experimental data from the direct-start process of the second, third, and fourth cylinders, aiming to enhance the characteristics of combustion and emission performance through the optimization of injection timing, equivalence ratio, and ignition timing. The research findings indicate that… More >
