Sutomo, Murni, Senen, Rahmat, Electrolyzer is development of a electrolysis technology to produce HHO gas, or Brown’s gas. Diesel engine use solar (diesel oil) as combustion’s material to produce thermal energy and oxidation and will be changed to mechanic energy. The base product of thermal energy by oxidation diesel oil, is would like to use electrolyzer to produce HHO and insert to the fuel combustion. Because HHO is a reactive gas, so in our research we hopeful will increase the thermal energy in combustion process and decrease the diesel oil consumption. The result of this research is the BSFC (Brake Shat Fuel Consumption) will decrease 2.5% up to 3.2%.   Key word: electrolyzer, diesel engine, BSFC

Sutomo, Murni, Rahmat, An internal combustion process of fuel will works effectively if the fuel’s density and viscosity is lower so we would like to use a heater in order to decrease the density and viscosity of the fuel. Based on this condition, we would like to use an electrolizer and a diesel engine to improve the fuel consumption. Electrolizer will increases the gas reaction so we hope that fuel consumption rate will decrease. The result of this research is the effective temperature of fuel is 50oC – 60oC will produce the effective combustion. The fuel consumption decreased in 6 kW is 0.12 lt/kWH.

Vegetable oils, when subjected to transesterification process generate “vegetable oils esters”, with similar properties as density, cetane number, heating values, air-fuel ratio. However, problems resulting from the higher viscosity, leads to a worst spraying and combustion, formation of undesirable deposits on engine parts and contamination of the lubricant oil. Due to these problems, it is interesting to study an additive, also derived from biomass, to improve the characteristics of biodiesel for a suitable use in diesel engines. This paper proposes an additive (d-limonene obtained from orange peel) and preliminary results obtained from the tests in a stationary diesel engine fueled with mixtures of diesel/biodiesel/d-limonene, in different concentration to compare with a regular diesel-biodiesel blend and analyzes the influence of the additive on the combustion process. The diesel oil used was purchased from BR supply network (containing 7% biodiesel in its composition) and two blends with different concentrations of the additive (1% and 3% of d-limonene) were prepared and tested. Diesel without additive was also tested. The effects of the DS10 addititivation with d-limonene in the combustion process of a diesel engine have been analyzed, the results obtained were satisfactory showing the positive effects in the combustion process with the addition of d-limonene in diesel-biodiesel blends, decreasing the ignition delay around 2 degrees and showing an improvement in the cetane number of the fuel.

In the fuel injection pump on crude oil engine, the precise couple attrition will cause loss of oil supply pressure, oil consumption increase, under-power, emission pollution increase and other problems after the long-term usage. The traditional filed-strip is complicated and time-consuming. Through the summary of engine trouble regulation, we can find out fault diagnosis without disassemble has guiding significance for the modern vehicle maintenance and repair. This article realizes the test and application of fault diagnosis for diesel oil supply characteristic through testing oil supply pressure and oil supply diesel engine.

Abstract This paper concerns analysis of possible use of alcohols for the feeding of self - ignition and spark-ignition engines operating in a dual- fuel mode, i.e. simultaneously combusting alcohol and diesel oil or alcohol and petrol. Issues associated with the requirements for application of bio-fuels were presented with taking into account National Index Targets, bio-ethanol production methods and dynamics of its production worldwide and in Poland. Te considerations are illustrated by results of the tests on spark- ignition and self- ignition engines fed with two fuels: petrol and methanol or diesel oil and methanol, respectively. Te tests were carried out on a 1100 MPI Fiat four- cylinder engine with multi-point injection and a prototype collector fitted with additional injectors in each cylinder. Te other tested engine was a SW 680 six- cylinder direct- injection diesel engine. Influence of a methanol addition on basic operational parameters of the engines and exhaust gas toxicity were analyzed. Te tests showed a favourable influence of methanol on combustion process of traditional fuels and on some operational parameters of engines. An addition of methanol resulted in a distinct rise of total efficiency of both types of engines at maintained output parameters (maximum power and torque). In the same time a radical drop in content of hydrocarbons and nitrogen oxides in exhaust gas was observed at high shares of methanol in feeding dose of ZI (petrol) engine, and 2-3 fold lower smokiness in case of ZS (diesel) engine. Among unfavourable phenomena, a rather insignificant rise of CO and NOx content for ZI engine, and THC and NOx - for ZS engine, should be numbered. It requires to carry out further research on optimum control parameters of the engines. Conclusions drawn from this work may be used for implementation of bio-fuels to feeding the combustion engines.

NOx forms during a combustion process and contributes to ozone, smog, acid rain, eutrophic soil, etc. The use of water to prevent NOx formation during the combustion process is well known. Adding water to the combustion process reduces the flame temperature by increasing the specific heat capacity of charge air. Moisturizing a charge air is one of the most effective methods to add water to the combustion process. In this study, the characteristics of charge air moisturizing method were evaluated on cylinder pressure, heat release rate, exhaust gas temperature, specific fuel oil consumption, NOx reduction rate, etc., using the medium speed diesel engine with a single cylinder.

The Stability

The main objective of this study was assessment of the performance, emissions and combustion characteristics of a diesel engine using RME–1-butanol blends. In assessing the combustion process, great importance was placed on evaluating the stability of this process. Not only were the typical COVIMEP indicators assessed, but also the non-burnability of the characteristic combustion stages: ignition delay, time of 50% heat release and the end of combustion. The evaluation of the combustion process based on the analysis of heat release. The tests carried out on a 1-cylinder diesel engine operating at a constant load. Research and evaluation of the combustion process of a mixture of RME and 1-butanol carried out for the entire range of shares of both fuels up to 90% of 1-butanol energetic fraction. The participation of butanol in combustion process with RME increased the in-cylinder peak pressure and the heat release rate. With the increase in the share of butanol there was noted a decrease in specific energy consumption and an increase in engine efficiency. The share of butanol improved the combustion stability. There was also an increase in NOx emissions and decrease in CO and soot emissions. The engine can be power by blend up to 80% energy share of butanol.
