Knock In Various Combustion Modes in a Gasoline-Fueled Automotive Engine

Popis výsledku v původním jazyce

Homogeneous charge compression ignition (HCCI) offers great potential for improved fuel economy and dramatically reduced NOx emissions, compared to typical spark ignition (SI) combustion. However, the benefits of HCCI are limited to low and medium loadsby the simultaneous occurrence of combustion instability and knock at a maximum load that is too low for conventional SI combustion. To provide smooth operation in the intermediate range between HCCI and SI requires alternative combustion strategies. Onesuch strategy is spark-assisted compression ignition (SACI), which uses a spark plug to initiate a flame that consumes a portion of the mixture, followed by autoignition of the remaining charge. This moderates the rapid heat release and allows higher loads to be achieved without exceeding knock and stability limits. In a recent study, we have explored this region and have found that spark assist at first dramatically reduces knock as load is raised above the HCCI limit; however, with fu
