Computational study on the ignition timing of HCCI combustion in IC engines fuelled with methane
conference contribution
posted on 2011-05-04, 10:17 authored by Rui Chen, Nesa Milovanovic, Don LawEngines with Homogeneous Charge Compression Ignition (HCCI) combustion offer a number
of benefits over conventional SI and CI combustions, such as low NOx emission, negligible
cycle-to-cycle variation, higher combustion efficiency at part load than SI counterpart at part
load, and low soot emission. Unlike SI and CI engines, where combustion is directly
controlled by the engine management system, the combustion in HCCI engines is controlled
by chemical kinetics only. Sophisticated strategies for ignition timing and rate of heat release
control over wide engine operation range need to be developed. Using SENKIN chemical
kinetics simulation package developed by Sandia, the effect of a number of engine operation
parameters on the ignition timing of HCCI combustion has been calculated. Results were
analysed and reported in this paper. It has been found that a high inlet temperature can be
used to initiate the HCCI combustion, but EGR and air/fuel ratio appears to be the potential
practical methods for ignition timing and engine load control.
