There are many studies showing that the performance results for engines operating with biofuels are acceptable, although very few long-term analysis of wear and maintenance problems are shown. Three mono-cylinder compression ignition engines were tested for approximately 1000h each, with pure...

The need to decrease the consumption of materials and energy and to promote the use of renewable resources, such as biofuels, stress the importance of evaluating the performance of engines based on the second law of thermodynamics. This paper suggests the use of exergy analysis (as an...

The effect of fuel inlet temperature on performance, emission and combustion characteristics of a diesel engine is evaluated. A single cylinder direct injection diesel engine developing a power output of 2.8kW at 1500rev/min is tested using preheated animal fat as fuel. Experiments are conducted...

The application of proton exchange membrane (PEM) fuel cell technology within the automotive industry is turning into reality what was until quite recently a utopian vision. The use of hydrogen as a fuel source is the latest advance in the so-called new wave technologies - earlier technological...
