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...

Ethanol is blended with pure gasoline for use as a fuel in engine. It required to conduct physical tests on engines observe the engine performance these blends. However, mathematical equations provide quick, effective, and accurate alternate tests. may not be possible develop relations specific operating conditions of fuel. dimensional analysis approach model. Dimensional used this research wor...

Nitrogen oxides (NOx) contribute to a wide range of environmental effects including the formation of acid rain and destroy ozone layer. In-cylinder high temperature flame and high oxygen concentration are the parameters which affect the NOx emissions. The EGR system is a very effective way for reducing NOx emission from a diesel engine (via reduction of these parameters), particularly at the...

Recycling used plastic can help reduce the amount of waste generated. Existing methods, namely process pyrolysis, are chemical heating processes that decompose plastics in absence oxygen. This decomposes a controlled environment order to produce fuel from waste. The present study consequently investigated physical and properties pyrolysis oil derived bottle caps (WPBCO) effects on engine perfor...

In this study, engine performance on thermal factors for different biodiesels has been studied and compared with diesel fuel. Biodiesels were produced from Pongamia pinnata (PP), Calophyllum inophyllum (CI), waste cooking oil (WCO), acid oil. Depending their free fatty content, they subjected to the transesterification process produce biodiesel. The main characterizations of density, calorific ...

This study investigates the use of di-ethyl ether (DEE) as an oxygenated additive with 20% Karanja methyl ester diesel blend (B20). Experiments were conducted to study the effect of adding 5%, 10% and 15% di-ethyl ether (DEE) with Karanja methyl ester (KME) on performance, emission and combustion characteristics of a direct injection diesel engine operated at a constant speed of 1500 rpm at dif...

In this work, different ethanol ratios (5%, 10%, 15%, and 20%) blended with biodiesel were used to investigate the effects of addition on engine performance, combustion, emission characteristics a high-speed diesel in terms brake power, specific fuel consumption, thermal efficiency, cylinder pressure, temperature, heat release rate, NOx, CO, soot emissions. First, three-dimensional CFD model wa...

During short term engine operation, renewable fuels derived from vegetable oils, are capable of providing good engine performance. In more extended operations, some of the same fuels can cause degradation of engine performance, excessive carbon and lacquer deposits and actual damage to the engine. Moreover, temperatures in the area of the injector tip due to advanced diesel injection systems ma...

Biodiesel is one of the promising renewable, alternative and environmentally friendly biofuels that can be used in diesel engine with little or no modification in the engine. In the present study an experimental investigation has been carried out on the combustion and performance characteristics of a CI engine running with biodiesel under steady state operating conditions. The experimental work...

The scarcity of petroleum products is forcing renewable energy resources to be more attractive. Biodiesel an alternative fuel created through the transesterification vegetable oils and animal fats. most important biodiesel quality parameters are obtained by paying attention making a trade-off between reaction time temperature. presence contaminants in feedstock, such as water free fatty acids, ...
