Test Results for Toxicity and Reducing Toxic Exhaust Emissions of the Marine Diesel Engine

Abstract

The tests were carried out on the marine diesel engine operating by the load characteristic in seven modes, including five modes according to the test cycle D2 regulated by ISO 8178. Based on the experimental results obtained, the specific weighted NOx emissions and their average values were calculated and compared with IMO regulations. In addition, the study carried out a comparative experimental investigation on diesel fuel and dimethyl ether, and different injector opening pressures in the marine diesel engine to reduce its toxic exhaust emissions.
