Effects of Compression Ratio and Simulated EGR on Combustion Characteristics and Exhaust Emissions of a Diesel PCCI Engine
The effects of compression ratio and simulated exhaust-gas recirculation (EGR) on combustion characteristics and exhaust emissions of a diesel PCCI engine were investigated using a single-cylinder test engine.Tests were Vacuum carried out under constant speed with various compression ratios and EGR rates.Exhaust emissions and in-cylinder pressure w
