Reduction of Nox in Single-Cylinder Diesel Engine

—Effect of Combustion Chamber Shape on NOx under wide range operation condition—

Abstract

To investigate the combustion characteristics of engines for marine use, tests conducted on various combinations of fuel nozzles and piston bowls using single-cylinder diesel engine with a cylinder bore of 165mm. The effect of individual factors on NOx and Smoke were confirmed by changing engine speed and brake torque. It provided information on the difference in combustion characteristics depending on the piston bowl shape.
