Model Based Control for Automatic Compensation of Combustion Noise and Smoke

Abstract

Premixed Charged Compression Ignition (PCCI) is focused because of high required for environment. However Combustion Noise (C.N.) and Smoke increase while switching conventional and PCCI combustion. The purpose of this study is compensation of C.N. and Smoke in several environment and driving condition. Prediction model of C.N. and smoke and injection spray model with considered cylinder space were built. We developed controller with combined these models, it could automatically calculate optimal injection pattern to compensate C.N. and Smoke.
