Low-temperature and premixed combustion can simultaneously reduce NOx, smoke, and combustion noise without any deterioration in thermal efficiency. Experimental investigations were conducted on a single-cylinder, direct-injection diesel engine to examine the effects of GTL fuel with various cetane numbers, the compression ratio of HC emission reduction in a cold running condition that incorporated the new combustion. The mechanism of emission improvement was also analyzed using 3- dimensional computations. Based on these results, we suggest a future direction in combustion system specifications and fuel properties for a clean diesel engine.
