Compression Ratio and Multifuel Capability 640372

This paper describes tests conducted to determine the effect of increased compression ratio on the multifuel capability of a standard diesel engine. The tests included power and cold starting capability checks, and it was found that the thermal efficiency was increased, combustion at full-load was improved, and part-load operation was definitely improved. Although there was no major improvement in cold starting characteristics as a result of increased compression ratio, the warm-up characteristics of the engine were markedly improved.
