摘要: Polyoxymethylene dimethyl ethers (PODEs) are an excellent blend for diesel due to their high cetane number, oxygen content, and low viscosity. Combustion emission characteristics investigated based on experimental tests a turbocharged, in-line 6-cylinder, common rail engine. Results show that combustion starts earlier with PODE blending at partial loads. With pilot main injection, the peak pressures heat release rates of diesel/biodiesel/PODE fuels increase large amounts reactive radicals formed in stage. load, slight decrease both pressure rate is observed. At loads, CA10s, CA50s, CA90s advance, rapid late phases shorten. medium CA10s CA50s remain unchanged, clearly advance. Rapid very little, whereas th...
