Effect of Intake Valve Late-closing on Engine Performance of Light Duty Diesel Engine for Commercial Vehicles
Recent tendency of diesel engine for passenger car is decreasing compression ratio for suiting severe emission and fuel economy regulation. The lower compression ratio is advantageous to reduce emissions. However, higher compression ratio might be better to have higher theoretical thermal efficiency. Because the Miller cycle with the late closing of intake valve gives lower compression ratio than expansion ratio, it can decrease temperature at compression end. In this report, the Miller cycle technology was adapted to a light duty diesel engine and the effects of emissions and fuel economy were examined. Using a Miller cycle, the fuel consumption and the soot emission were reduced without the penalty of NOx emission in Japanese engine emission test cycle (JE05).
