Abstract

A supercharged natural gas compression ignition engine has been tested to confirm the performance as well as the exhaust gas characteristics. The supercharging improved the thermal efficiency through the improvement of the combustion efficiency, the mechanical efficiency, and the cooling loss. The indicated thermal efficiency becomes the highest when in-cylinder temperature is about 1 700 K, due to the improved combustion efficiency and the decrease of cooling loss. The supercharging also reduces the NO_x emission. This is because the maximum temperature is kept low while the combustion efficiency is kept high compared with the natural aspiration. The pressure at auto-ignition inceased in case the boost pressure is raised. However, the auto-ignition temperature is the same and 1 000-1 030 K.
