The combustion and emission characteristics of ethyl levulinate (EL)– diesel blended fuels were investigated using engine bench tests. Blended fuels properties, including the kinematic viscosity (KV), density, EL proportions, oxygen content, cetane number (CN), and lower heating value (LHV) were considered. The combustion and emission characteristics of brake-specific fuel consumption (BSFC), a...

In this paper, technique for order of preference by similarity to ideal solution(TOPSIS) method is used to find the best compromising design of intake manifold for a 3-cylinder engine considering mean value of torque, torque at 3500 rpm, mean value of brake mean specific consumption (BSFC) and BSFC at 3500 rpmas four objective functions. To calculate the objective functions, engine simulation i...

This study investigates how high levels of exhaust gas recirculation (EGR) combined with certain fuel injection strategies and energy recovery systems affect diesel engine emissions and fuel economy. The key test apparatus was a John Deere 4.5L diesel engine which was modeled using the computer-based engine simulation tool GT-Power. The conclusion was made that utilization of high EGR levels (3...

In the current work, a comprehensive study on the possibility of using methanol as an alternative fuel for diesel engines was carried out. Methanol was mixed at different ratios with diesel fuel. The mixing ratios of methanol to diesel were 0:100, 10:90, 20:80 and 30:70. The effects of methanol fraction on engine power, torque, brake specific fuel consumption (BSFC), brake thermal efficiency an...

In this paper, validated simulations using Ricardo WAVE have been performed to investigate the effect of Miller cycle and low-carbon fuels on performance (power, torque, BTE BSFC) emissions a diesel engine. The results show that increased (larger deviation advanced or retarded intake valve closing from standard time) will decrease NOx, CO HC emissions, slightly improve brake thermal efficiency ...

In the present study, performance parameters of a single-cylinder, air-cooled spark ignition (SI) engine using fusel oil-gasoline fuel blends were predicted by artificial neural network (ANN). The SI was operated with gasoline/fusel oil (10% and 20%) at different load (1000, 2000, 3000, 4000, 5000, 6000, 7000 8000 Watt) compression ratios (8.00, 9.12 10.07) to obtain data essential create ANN m...

Author is pointing at the possibility of the utilisation of simulated computations for the research and development of the Car TDI diesel engines. Modern technical potential of them is discussed in the opening part of the paper with emphasis on the Latest Fuel Injection Technology. In this part of the paper one can find a short characteristics of the Engine, Exhaust Gas Recirculation, Selective...

In this experimental study, the effect of creating an air jet inside the combustion chamber by establishing an air-cell inside of the piston body at different injection timings in a DI diesel engine has been studied at 2000 rpm and full load operation. The performed tests include studying the Soot and NOx emissions, combustion and performance parameters. The obtained experimental results show t...

One of the major drawbacks of IC engines is low efficiency and pollution resulting from incomplete combustion. In order to improve the emission properties and performance an oxygenated additive MTBE (Methyl tertiary butyl ether), is blended with gasoline. A four cylinder, 1817 cc engine was used for analysing both emission and performance characteristics. Tests were carried out with 100% pure g...
