Increase in energy demand, stringent emission norms and depletion of oil resources have led the researchers to find alternative fuels for internal combustion engines. On the other hand, waste oils pose a very serious environment challenge because of their disposal problems all over the world. In this context, waste oils are currently receiving renewed interest. The properties of the oil derived...

In this study; metanol-diesel fuel, organometal MnO2 fuels were used to improve the properties of diesel fuel. Besides, the effect of methanol fuel on engine oil was also examined experimentally in a four cylinder, direct injection diesel engine running at 200 bar. Three different diesel fuels were prepared by adding 5, 10 and 15% methanol into diesel fuel. In order to prevent phase separation ...

Experimental work was done to examine the impact of diesel fuel with alumina nanoparticles on combustion characteristics, emissions and performance engine. Alumina were mixed crude in various weight fractions 20, 30, 40 mg/L. The engine tests showed that nano addition ppm pure led thermal efficiency enhancement up 5.5% related fuel. average specific consumption decrease about neat found be 3.5%...

We show that the cost of increasing biofuel mandates given a binding ethanol blend wall will fall disproportionately on diesel fuel consumers. The extent of the burden on diesel fuel consumers is explained neither by their relatively more inelastic demand nor by blenders seeking to capitalize on the biodiesel tax credit. Relaxing the blend wall constraint by increasing the potential demand for ...

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...

Fuel injection is systems for supplying high pressurize fuel to maximum mixing of fuel with air in an internal combustion engine. Direct Injection (DI) Systems as used in DI engines, in which the fuel is injected directly into a combustion chamber formed in the clylinder itself. The fuel injector directly injects fuel into the direct fuel injection system. The injector is a very complicated par...

diesel fuel has a limited resource and concerns over environmental pollution areleading to the use of ‘bio-origin fuels’ as they are renewable and environmentally benign. jatrophamethyl ester, an esterified biofuel, has an excellent cetane number and a reasonable calorific value.it closely resembles the behaviour of diesel. however, being a fuel of different origin, the standarddesign limits of...
