    Analysis of physicochemical and operational performance of petroleum and alternative motor fuels showed that their lower heat of combustion can differ significantly. However, the heat of combustion of fuel-air mixtures of these fuels differs slightly. Therefore, the assessment of energy and fuel-economic performance of the engine during its operation on different fuels is proposed to do the calculation method for the consumption and heat of combustion of fuel-air mixtures. According to the developed method, engine power and fuel consumption during engine operation on biodiesel, biomethane and petroleum diesel fuel were determined. To determine the heat of
    combustion of fuel-air mixtures, the lower heat of combustion of fuels was used. Fuel-air consumption was determined by engine displacement and crankshaft speed. The tests show that the highest power and lowest fuel consumption of the engine running on petroleum diesel fuel and slightly worse values of the engine running on biodiesel. The gas engine with spark ignition converted from diesel running on biomethane shows the lowest indicators.

    HOW DOES 10% ETHANOL COMPOSITION OF GASOLINE AFFECT CAR ENGINE PERFORMANCE

    Machines. Technologies. Materials., Vol. 10 (2016), Issue 10, pg(s) 3-5

    Ethanol is a renewable, domestically produced alcohol fuel made from plant materials, such as corn, sugar cane, or grasses.
    Using ethanol we can reduce oil dependence and greenhouse gas emissions. Ethanol fuel used in the U.S. has increased dramatically from about 1.7 billion gallons in 2001 to about 13.4 billion in 2014. E10 is now the standard replacement for traditional unleaded. Over 90% of all unleaded sold today contains ethanol.

    In this paper it has been examined the influence of the E10 fuel mixure on some car engine performance.

  • THE HEAT BALANCE OF ENGINE FED BY DIESEL OIL AND BMD BIOFUEL

    Machines. Technologies. Materials., Vol. 8 (2014), Issue 4, pg(s) 38-40

    In the present paper the issue of external heat balance in the diesel engine is presented. The methodology of heat balance estima- tion, as well as the comparison of the researches results concerning engine with the common rail injection system, which is fed by mineral diesel oil and BMD biofuel has been presented. The impact of biofuel on the nature of changes in the heat balance has been estimated. The researches were performed on the measurement station based on the 13 points ESC test. It has been stated that the use of fuel assigned in the ESC test in the engine fed by biofuel (BDM) slightly increases in comparison to the engine fed by mineral diesel oil (ON). However, there can be noticed the change of the flow of energy input in the heat balance of the engine fed by both types of fuel.
