在直喷式柴油机上进行了含氧十六烷值改进剂二乙醚（DEE）与煤油、柴油混合对柴油机燃烧、性能和排放特性影响的试验研究。最初，将2%、5%、8%、10%、15%、20%和25%的DEE（按体积计）掺合到柴油中。DEE-柴油混合燃料降低了柴油机PM和NOx的平衡，并找到了最佳性能的混合燃料DE 15 D。同样，将5%、10%和15%的煤油（按体积计）掺入柴油中以考察掺杂效果。此外，通过与5%、10%和15%煤油（按体积计）混合，进行了一项研究以评估煤油掺杂对DE 15 D的影响。对于所有试验燃料，在10%、25%、50%、75%和100%满负荷下进行发动机试验。实验室燃料试验表明，DEE与柴油和煤油以任何比例完全混溶。结果表明，随着DEE添加量的增加，共混物的密度、运动粘度和热值降低，而氧含量和十六烷值增加。试验结果表明，DEE-煤油-柴油混合燃料与DE 15 D混合燃料相比，具有较低的制动热效率、较高的制动燃油消耗率、较高的全负荷烟度、较低的部分负荷烟度、较低的NO含量、相近的CO含量、较高的全负荷HC含量和较低的部分负荷HC含量。
An experimental investigation had been carried out to evaluate the effects of oxygenated cetane improver diethyl ether (DEE) blends with kerosene and diesel on the combustion, performance and emission characteristics of a direct injection diesel engine. Initially, 2%, 5%, 8%, 10%, 15%, 20% and 25% DEE (by volume) were blended into diesel. The DEE–diesel blends have reduced the trade-off between PM and NOx of diesel engine and the optimum performance blend has been found as DE15D. Similarly, 5%, 10% and 15% kerosene (by volume) were blended into diesel to investigate the adulteration effect. In addition, a study was carried out to evaluate the effects of kerosene adulteration on DE15D by blending with 5%, 10% and 15% kerosene (by volume). The engine tests were carried out at 10%, 25%, 50%, 75% and 100% of full load for all test fuels. Laboratory fuel tests showed that the DEE is completely miscible with diesel and kerosene in any proportion. It was observed that the density, kinematic viscosity and calorific value of the blends decreases, while the oxygen content and cetane number of the blends increases with the concentration of DEE addition. The experimental test results showed that the DEE–kerosene–diesel blends have low brake thermal efficiency, high brake specific fuel consumption, high smoke at full load, low smoke at part load, overall low NO, almost similar CO, high HC at full load and low HC at part load as compared to DE15D blend.
