Abstract
One of the problems encountered when operating Diesel engines in HCCI mode is a too early start of combustion, due to the low ignition resistance of Diesel fuels. Correct phasing of the combustion process requires a lower in-cylinder temperature during compression. One possibility of regulating the temperature is to adjust the intake valve closing timing and thus the effective compression ratio.
A single cylinder research engine, configured as a passenger car type DI Common Rail Diesel engine, was fitted with a fully adjustable hydraulic valve train, which allowed free settings of the valve timing events. Premixed combustion was achieved by injecting the fuel during the compression stroke, prior to ignition, in multiple steps. Different combinations of intake valve closing timing and external EGR were tested as well as the possibility to use internal EGR for combustion control. The results showed that accurate control of Diesel HCCI combustion phasing and rate is possible when valve timing can be freely adjusted.
