The Effect of Increasing of Compression Ratio and Peak Cylinder Pressure on High-Boosted and High Rate EGR Diesel Combustion in a Single-Cylinder Engine
Published May 19, 2010 by Society of Automotive Engineers of Japan in Japan
Event: JSAE Spring Conference
The effect of changing compression ratios (ε=14~22) on fuel consumption has been studied. As results of experiment ε=18 can improve fuel consumption without remarkable deterioration on exhaust emissions. With ε=18, the high-boosted and high EGR rate diesel combustion which has the feature of Pmax=28 MPa and high degree of constant volume ηgl was experimented at full load for the improvement of fuel consumption. And the minimum fuel consumption (BSFC=181.2 g/kWh, ηe=46.3%) was achieved by these engine specifications.
