Combustion Improvement of Diesel Engines With Alcohol Addition~Investigation of Port Injection Method and Blended Fuel Method
Published September 29, 2010 by Society of Automotive Engineers of Japan in Japan
The potential of alcohol addition by port injection and blended fuel was for improving combustion in diesel engines was investigated, in addition to the utilization of an alternative fuel produced from cellulose. NOx reduction and thermal efficiency improvement at middle and high loads were achieved as a result of the characteristics of oxygen content, low cetane number and low viscosity of the fuel. However, thermal efficiency worsened due to unburned fuel loss at low loads. Differences in soot generation were analyzed by combustion visualization using an optical research engine.
