Abstract: In this paper, a four-stroke engine diesel was employed to investigate the effects of different fuel mixture ratios of diesel and ethanol on engine performance and emission characteristics in terms of cylinder temperature, heat release rate, brake power, brake thermal efficiency, brake specific fuel consumption, and cylinder pressure. The corresponding simulation model of diesel engine was developed by AVL-Fire coupled CHEMKIN code, and an improved chemical kinetics mechanism containing 34 reactions and 19 spe… Show more

“…The working process of the diesel engine in-cylinder includes complex and integrated processes such as heat transfer, flow, physics, and chemistry. Its basic differential equation is one of the most fundamental equations in simulation calculation [42]. In addition, in diesel engine engineering technology, optimization technology plays a very important role and significance in the process of diesel engine development decision making [43].…”

“…On the contrary, in order to minimize heat loss, lowpower systems will tend to use more insulating materials [199]. It was believed that the heat loss had great influences on extinction and the wall thermal conductivity greatly affects blowout [200]. In addition, Li et al [201] indicated that the increase of the wall thermal conductivity could increase the critical blowout velocity, suggesting the importance of operation of catalytic micro combustors and thermal management in the design.…”

“…The results showed that diesel-biodiesel blends could improve the emission characteristics. Based on previous studies, the results obtained showed that biodiesel fuel could decrease PM, CO, HC and NO x emissions [26,27], although, on the other hand some experiments on biodiesel also showed that NO x emission concentration increased [28,29]. Therefore, it is very important to further study the impact of biodiesel on diesel engine emission and combustion characteristics.…”
