Abstract The performance and emission of a small diesel engine fuelled by commercial fuel in Indonesia are present this paper. Various fuels produced marketed Pertamina. As the largest oil company Indonesia, Pertamina has developed various fuels, namely Solar, Biosolar (B30), Dexlite, Pertadex. This study explains more detail performance, consumption, four types they were investigated experimen...

In this study, the performance of a single cylinder four stroke direct injection (DI) diesel engine is analyzed in the light of first law of thermodynamics. An energy balance study is carried out to quantify the various losses associated with diesel engine processes on the basis of experimental performance and emission data. The engine was fuelled with normal diesel and Jatropha Methyl Ester (J...

Abstract Background The present study presents a 3-D numerical simulation of direct injection diesel engine powered by base oil and soybean biodiesel fuel at different load conditions. modeling was performed using commercial computational fluid dynamics (CFD) software linked to chemical solver. A kinetic reaction mechanism developed simulate the combustion spray processes. Base results were ver...

Stringent emission standards and greater fuel economy have forced scientists to develop an advanced combustion technology (homogeneous charge compression ignition; HCCI) useful in internal engines the future. Citronella biodiesel prepared through transesterification process which is auspicious energy source for CI engine. Cobalt chromium nanoparticles were mixed with at 30 ppm help of ultrasoni...

Energy is primarily obtained from fossil fuels and with the use of fuels, we are increasing emissions greenhouse gases. It takes constant effort to meet energy need environmentally acceptable renewable fuels. In order find a replacement for depleting fuel energy, range oxygenated was investigated based on their accessibility geographic areas. This work assessed transesterification process’s fea...

The possibilities to simulate fuel consumption and optimize a vehicle’s powertrain to fit to the customer’s needs are great strengths in the competitive bus industry where fuel consumption is one of the main sales arguments. In this master’s thesis, bus specific powertrain component models, used to simulate and predict fuel consumption, are validated using measured data collected from buses. Ad...

The climate change issue has become a growing concern due to the increasing greenhouse gas emissions. To achieve carbon neutrality for mitigating problem, oxy-fuel combustion (OFC) technique on internal engines (ICEs) attracted much attention. Furthermore, water injection (WI) strategy was proven effective in improving process and thermal efficiency under OFC mode. However, WI effects gasoline ...

In this paper, biodiesel was used as an alternative fuel to investigate the combustion and emission characteristics of a four-stroke diesel engine, in terms cylinder pressure, heat release rate, temperature, brake thermal efficiency, specific consumption, nitrogen oxide, soot, carbon monoxide, hydrocarbon. Firstly, engine model developed by AVL-Fire software coupled with CHEMKIN code simulate i...

The aim of the present study was to investigate effects application hydrotreated vegetable oil (HVO) mixed with pure duck fat (F100) as fuel, replacing conventional fossil diesel fuel (D100). tests were performed using a four-stroke direct injection CI engine engine. Six samples used: D100, HVO100, F100, well three HVO–fat mixtures F25, F50, and F75. To further main characteristics combustion, ...

Experimental data for Wankel rotary engine performance on hydrogen blends with hydrocarbon fuel is presented. Researches are performed partial loads and idle. Hydrogen mass fraction additions to the mixture didn’t exceed at 5% idle mode 9%. The excess air ratio was stoichiometric. It shown that (20% of full load) speed 2000 per minute addition yields 4.2% decrease brake specific consumption (hy...
