Abstrakty
HCCI engine offers a high thermal efficiency combined with low nitrogen oxides and particulate matter emissions. However the key problem: controlled autoignition (CAI) on which is focused this paper is still not solved. Attempts to solve CAI problem as: variable compression ratio (VCR), variable valve train (VVT), exhaust gas recirculation (EGR) and application of fuels having different volatility characteristics and sensitivity to autoignition are disused. Also possibility of fuelling HCCI engine with natural gas (and ignition improver) is presented.
Silnik o zapłonie samoczynnym zasilany homogeniczną mieszanką (HCCI) oferuje wysoką sprawność przy małej emisji tlenków azotu i cząstek stałych. Jednakże główny problem, jakim jest kontrolowany samozapłon, nie jest jeszcze rozwiązany. Na tym problemie skupia się niniejszy artykuł. Omówiono metody rozwiązania problemu kontrolowanego samozapłonu, takie jak: zmienny stopień sprężania, recyrkulacja gazów wylotowych, zmienne fazy rozrządu oraz zastosowanie jednocześnie dwu paliw o różnej lotności i skłonności do samozapłonu. Przedstawiono także możliwość zasilania silnika HCCI gazem naturalnym (CNG) przy jednoczesnym udziale składników ułatwiających samozapłon.
