IGNITION CONTROL METHOD OF HCCI COMBUSTION AND HCCI ENGINE

摘要

An ignition control method of homogeneous charge compression ignition combustion and a homogeneous charge compression ignition engine are provided to minimize the harmful material among the exhaust gas. A ignition control method of homogeneous charge compression ignition(HCCI) performs the following steps: a first step which sprays the reserve fuel before the temperature of the cylinder inside reaches the combustion starting temperature(S100); a second step spraying the control fuel before the combustion start of the reserve fuel(S200); a 2-1 step where the temperature of the cylinder inside descends to the constant temperature with the vaporization latent heat of the control fuel and the combustion start time is delayed(S210); a 2-2 step where the reserve fuel and the mixer in which the control fuel is mixed are compressed in the cylinder inside(S220); and a 2-3 step at the same time, where mixer discloses the combustion is included(S230).
