The impact of fuels and fuelling strategy on enabling of clean combustion in a diesel engine

Due to the low volatility and high reactivity of conventional diesel fuels, the efficient combustion of a highly homogenous cylinder charge is normally limited to low loads. When the compression ratio, and thus the expansion ratio for prevalent engine designs, is substantially lowered to accommodate higher loads, the energy efficiency of the cycle is significantly reduced. In this work, with a high compression ratio of 18.2:1 kept intact on a …
