摘要

The effects of RCCI in a diesel power generator by using safflower oil biodiesel-diesel blends were experimentally investigated. Ethanol was premixed as PFI by rates of 30% and 50% of total mass fuel consumption of the engine. Tests were conducted at constant engine speed of 1500 rpm and fixed load 10.8 kW engine power. The purpose of blending biodiesel with diesel is to increase the fuel reactivity of primary fuel in order to easily initiate the combustion. Therefore, test fuels were prepared by blending 10% of the biodiesel with 90% of diesel, 20% of the biodiesel with 80% of diesel and 50% of the biodiesel with 50% of diesel. The most important combustion, performance and emission indicators of the engine under various conditions have been deeply investigated and results have been presented. The ethanol RCCI operation increased peak pressure values especially with using of B50 as high reactivity fuel while combustion was retarded for both RCCI modes. Overall, many indicators of the combustion was improved. Performance parameters were developed. Especially, bsfc was considerably increased. NOx, emissions were considerably decreased while CO and HC emissions were a bit increased. (C) 2016 Elsevier Ltd. All rights reserved.
