Title: Device for estimating timing for mixture ignition of internal combustion engine, and control device of internal combustion engine
Inventor: INAGAKI KAZUHISA
IPC: F02D41/38
Filed: 2004-03-24
Abstract: <P>PROBLEM TO BE SOLVED: To accurately estimate timing for self-ignition start of premix for PCCI combustion in consideration of calorific value produced by cool flames occurring partly in the premix prior to the self-ignition.  <P>SOLUTION: In the device for estimating timing for mixture ignition, temperature of the premix for PCCI combustion (i.e. cylinder temperature Tg) is estimated in correspondence with a crank angle CA, then a point in time when the cylinder temperature Tg has reached a specified self-ignition-starting temperature Tig is estimated as self-ignition-starting timing (CAig) for PCCI ignition of the premix. In this case, the estimation is done on the basis of a state variable of cylinder gas at compression-start time (CAin) (thermal energy of cylinder gas at compression-start time), a rate of change of the state variable of the cylinder gas caused by compression in a compression stroke (minimal piston work), and a calorific value (cool flame calorific value ΔQlto) of cool flame generated prior to self-ignition (hot flames) in PCCI combustion time. Since the cool flame calorific value ΔQlto is taken into consideration, the self-ignition start timing for the PCCI combustion can be exactly estimated.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
