A high speed gas sampling valve system for investigation in low temperature combustion of diesel engines
EF 2006-07
Résumé
The technique of low temperature combustion has been identified as a feasible pathway for modern diesel engines to produce ultra low emissions in nitrogen oxides (NOx) and particulate matter (PM). One of the advanced techniques to obtain the insights of combustion is through direct gas sampling that extracts a specified portion of cylinder charge and/or combustion products from inside of the engine combustion chamber within an assignable temporal window. The direct gas sampling technique will help to identify the origin and history of pollutant generation in modern diesel engines. Zheng and Reader have recently set up an embedded real-time controller that can produce up to eight discrete fuel shoots during each combustion cycle for a single cylinder common-rail diesel engine. In such engines, the ratio of premixed combustion to diffusion combustion can be raised significantly while the maximum rate of energy release can still be confined effectively, which commonly result in lowered nitrogen oxides (NOx) and particulate matter (PM) emissions. However, such modern combustion engines impose new challenges on combustion diagnoses. The cylinder charge has much higher overall pressure than in mechanical fuel injection diesel engines. The high-speed actuation of the direct sampling valve in the newer diesel engines requires a higher power drive that, in combination with the precision and sophistication requirements, leaves the requested system only to a handful of suppliers in the world. The research will produce data that has immense interests in the combustion sciences community and the automotive industry in Canada and worldwide. We have obtained substantial support in clean diesel engine researches from Ford Canada and ITEC. Notwithstanding, the industries has not extended their support to this combustion mechanism study. This research will complement the other combustion and emission control work currently being conducted by Drs. Zheng, Reader, and Ting at the clean diesel engine laboratory. Our recent breakthrough in diesel HCCI combustion and on-fly adaptive control has further enhanced our interest in the crank-angle resolved combustion analyses.
