Effect of various control strategies on gasoline compression ignition engine: a review

Abstract Download PDFThis paper introduces a new alternative combustion concept as well as a detailed
overview of the technique. GCI (gasoline compression ignition) is a promising
advanced combustion mode for increasing fuel economy and lowering emissions.
This is an innovative engine technology that uses the higher volatility of gasoline
and auto-ignition temperature, as well as a diesel engine"es higher compression
ratio (CR), to reduce soot and NOx emissions while maintaining diesel engine
efficiency. However, GCI engine has some challenges included cold starting, high
CO and HC emissions, combustion stability at part load, and high combustion
noise at medium-to-full load operations. Therefore, this paper reviews the
experimental, numerical, and optical studies to go over various aspects of GCI
engine technology, such as its combustion characteristics and controls.
Furthermore, this paper examines some experimental studies to assess the
potential benefits of GCI technology before pointing out future works. In various
control strategies on GCI engines, the fuel injection strategy is the best solution to
control the distribution of mixture concentration in the cylinder; adding additives
into gasoline can change the reactivity of fuel and extend the lower limit of the
stable combustion load of the GCI combustion method and coupling control
strategies may be used to achieve stable combustion.
