Abstract

<div class="htmlview paragraph">In order to reduce the knock of spark-ignition engines in the heavy load region, the effects of EGR on engine performance were investigated on two engines, one with a turbocharger and the other naturally aspirated with a high compression ratio.</div> <div class="htmlview paragraph">It was found that EGR was effective not only for reducing the knock, but also for improving the brake specific fuel consumption compared with the ignition timing retarding system.</div>
