The increase in the volume of vehicles resulted a crisis fossil fuels so there is need for alternative to replace gasoline. Butanol and Diethyl Ether (DEE) are that can be added This because Octane Number high O2 levels optimize combustion cylinder torque power save fuel. study compares addition butanol DEE gasoline on torque, power, Brake Specific Fuel Consumption (BSFC). used 160cc engine wit...

The preparation of air–fuel mixture is considerably dependent on fluid flow dynamics to achieve improved performance, efficiency, and engine combustion in the appearance of flow. In this study, the effects of mixtures of hydrogen and compressed natural gas (CNG) on a spark ignition engine are numerically considered. This article presents the results of a direct-injection engine using methane–hy...

The thermal balance analysis is a useful method to determine energy distribution and efficiency of internal combustion (IC) engines. In engines cooling concepts, estimation of heat transfer to brake power ratio, as one of the most significant performance characteristics, is highly demanded. In this paper, investigation of energy balance and derivation of specific heat rejection is carried out e...

In the present study, a computational fluid dynamics (CFD) method have been utilized to investigate the effects of exhaust gas recirculation (EGR) and initial charge pressure by means of using a supercharger on the emissions and performance of a SI engine. This engine is fueled separately by gasoline and two potential alternative fuels, hydrogen and ethanol. The results of simulation are compar...

Among human activities, motor vehicles play the most important role in air pollution. Air pollution has negative impacts on people and on the environment. In this paper the effect of oxygen-enriched air (20.8%, 21.8%, 22.8%, 23.8% and 24.8%) and different bioethanol-gasoline blends (zero, 5%, 10%, 15%, 20% and 25%) in different engine speeds (1000 rpm, 2000 rpm and 3000 rpm) on the amount o...

Alternative fuels, like a mix of pyrolyzed plastic waste and gasoline, have made us less dependent on nonrenewable petroleum. Since HDPE has low density, it is perfect for producing more oil at temperatures as 400oCelsius. It density around 0.94 g/cm3, whereas gasoline between 0.60 g/cm3 0.78 g/cm3. This study compared blend C10 C20 engine speeds 1500, 2000, 2500 rpm to C0 gasoline. Results ind...

The purpose of this paper is to review current studies concerning the relationship of fuel composition to vehicle engine-out and tail-pipe emissions and to outline future research needed in this area. A number of recent combustion experiments and vehicle studies demonstrated that reformulated gasoline can reduce vehicle engine-out, tail-pipe, running-loss, and evaporative emissions. Some of the...

This article analyzes the influence of the ignition retardation on the fuel consumption, the cumulative tailpipe hydrocarbon emissions, and the temperature inside the three-way catalytic converter in a gasoline direct injection engine operated under idling conditions. A dedicated cylinder-individual, model-based, multivariable controller was used in experiments in order to isolate the effect of...

The article discusses the possibility of using glycerol as an additive to engine fuel in order reduce tendency combustion knock, and thus increase octane number a given fuel. Experimental tests were carried out on UIT-85 research with variable compression ratio from eight eleven test intensity knock. completely renewable fuel—the blend butanol 25 75%, respectively—was tested. A comparative anal...

Hybrid electric vehicles are currently one of the most effective ways to increase efficiency and reduce pollutant emissions internal combustion engines. Green hydrogen, produced with renewable energies, is an excellent alternative fossil fuels in order drastically engine emissions. In this work, author proposes implementation a hydrogen-fueled hybrid vehicle; investigated powertrain power-split...
