Study of fuel inlet temperature variations on palm biodiesel operating with a diesel engine

Abstract

Abstract. Biofuel includes biodiesel is introduced to overcome the air pollution problems. Biodiesel is the sustainable and alternative fuel that derived from edible and non-edible oil produced from bio-originated species, plants, and animals. This paper presents the simulation analysis on the effect of fuel temperature variations on diesel engine performance and emission using palm-biodiesel. A one-dimensional numerical analysis, Diesel RK software is used to simulate a single cylinder, four-stroke diesel engine on the performance and emission when operated at a full load condition using fuel temperature variations ranging 300 K to 333 K. Results showed that simulated results for brake power and brake torque were 0.7% each when compared to the highest and lowest fuel temperature ranging from 333 K to 300 K. Moreover, higher fuel temperature for palm biodiesel tends to produce lower exhaust gas temperature and brake specific fuel consumption at a constant engine speed of 2400 rpm. It can be concluded that from the study, fuel temperature variations of biodiesel could produce a significant effect regarding engine performance and emission that influence the driving economy of the engine.

Improving the Performance and Emissions of a Four-Stroke, Water-Cooled, Di Diesel Engine by Increasing Inlet Air Temperature

“…Additionally, different fuels such as diesel and biodiesel were used in these investigations. A good agreement was observed between the model and experimental data, thereby validating the model [16][17][18][19][20][21][22][23][24][25]. This study experimentally investigates the effect of inlet air temperature on diesel engine performance and exhaust emissions.…”
