The world is presently confronted with the twin crisis of fossil fuel depletion and environmental degradation. Indiscriminate extraction and lavish consumption of fossil fuels have led to reduction in underground based carbon resources. The search for an alternative fuel, which promises a...

The rapid depletion of fossil fuels and environmental concerns make alternative fuels such as biodiesel more attractive. Biodiesel has properties comparable to ultra low sulfur diesel (ULSD), however certain properties of biodiesel such as viscosity, calorific value, density and volatility...

Engine performance improvement and exhaust emissions reduction are the two most important issues to develop a more efficient engine with less environmental impact. For a diesel engine, injection timing is one of the major parameters that affect the engine performance and emissions. Now-a-days,...

Alternative fuels have numerous advantages compared to fossil fuels as they are renewable and biodegradable besides providing energy security and foreign exchange saving addressing environmental concerns, and socio-economic issues as well. Therefore renewable fuels can be predominantly used as...

Investigations were carried out to evaluate the performance of a two-stroke, single cylinder, spark ignition (SI) engine, with alcohol blended gasoline (80% gasoline, 20% methanol by vol; 80% gasoline and 20% ethanol by volume) having copper coated engine [CCE, copper-(thickness, 300μm) coated...

The call for reduction in pollution has been mandated by government′s policies worldwide. This challenges the engine manufacturer to strike an optimum between engine performance and emissions. However with growing technology in the field of fuel injection equipment, the task has become...

Preprocessing of woody biomass was performed with torrefaction and low-temperature carbonization. In this study, the pretreated samples have been used to evaluate the energy yield and fuel characteristics. The combustion profiles of the torrefied sample and the low-temperature carbonized sample...

In this study, the effect of CR (compression ratio) on a SI (spark ignition) engine's characteristics of performance, combustion and emissions by using pure ethanol, methanol and unleaded gasoline were investigated experimentally. In the experiments, an SI engine having a CR of 8.5:1, having a...

The paper presents the research results pertaining to the renewable biomass charcoal–diesel slurries and their use as alternative fuels for combustion in diesel generating plants. The utilization of charcoal slurry fuel aims to reduce diesel oil consumption and would decrease fossil green...

The H2O concentration in real oxy-fuel combustion atmospheres is significantly higher than that in conventional air combustion, which strongly affects the combustion characteristics of pulverized coal. This study studies the effect of H2O on pulverized coal combustion behaviour in O2/CO2...
