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 hi...

The necessity for decrease in consumption of conventional fuel, related energy and to promote the use of renewable sources such as biofuels, demands for the effective evaluation of the performance of engines based on laws of thermodynamics. Energy, exergy, entropy generation, mean gas temperature and exhaust gas temperature analysis of CI engine using diesel and karanja methyl ester blends at d...

In the present study, the high viscosity of the jatropha curcas oil was decreased by preheating. The effect of fuel inlet temperature on performance of diesel engine is evaluated. A single cylinder, four stroke, constant speed, air cooled, direct injection diesel engine developing a power output of 3.7 kW at 1500 rev/min typically used in agricultural sector was tested using neat jatropha oil a...

This paper deals with analysis of the influence fuel injection pressure ternary (diesel + Mahua methyl ester Pentanol) on emission, combustion and performance characteristics a four stroke, single cylinder, common rail direct diesel engine working at constant speed varying operating scenarios. The usage raised NOx emission (12.46 %) value specific consumption (SFC) decrease in BTE (brake therma...

Currently, many countries are promoting B100 as the main fuel for diesel engines towards transition to 100% renewable energy applications. However, due its properties, has both advantages and disadvantages replace oil. Therefore, a bibliometric analysis was carried out evaluate performance emissions of engine with being tested on multi-cylinder cars. Unfortunately, only 12 127 selected articles...

The use of biofuel is one method for limiting the harmful impact diesel engines on environment. It also a way gradually becoming less dependent depleting petroleum resources. New resources producing biodiesel are currently being sought. authors produced esters from animal fat waste, obtaining fuel that can power and identifying to utilise unnecessary waste. methyl ester (AME) was using reactor ...

Abstract Cylinder deactivation is well-known in spark-ignited (SI) engines and compression-ignited (CI) engines. The major reason why the efficiency of these decreased at part load due to flow restriction intake system caused by partially closing throttle valves, which causes increased pumping losses. In order resolve this issue, cylinder can be implemented SI with four cylinders developing a s...

Electrinic Fuel Injection (EFI) a system that supplies fuel from the tank electronically with mixture of air suits needs so vehicle power remains maximum minimal consumption to produce environmentally friendly emissions. The injection is an innovation step being developed and applied motor vehicles today. purpose study was find out characteristics 2007 Honda Jazz I-DSI engine using parameters t...

Adjusting operating temperature of the engine in the steady state and during warm-up improves fuel consumption and reduces engine emission through higher operating temperatures. Also it can improve thermal comfort by faster cabin heater performance. Thermal fluid analysis by 1-D simulation is an effective tool for studying the control of the entire cooling system and optimization of engine perf...

In this experimental study, the effect of alcohol (ethanol and methanol) use on the performance, emissions and combustion characteristics of a low power single-cylinder engine described the rated power output of the engine e.g. 2 kW were investigated and the results were compared with conventional gasoline operation. The tests were performed at full-throttle valve opening and variable engine sp...
