Influence of oxygen enrichment on compression ignition engines using biodiesel blends

An investigation of the acoustic characteristics of a compression ignition engine operating with biodiesel blends

In this paper, an experimental investigation has been carried out on the acoustic characteristics of a compression ignition (CI) engine running with biodiesel blends under steady state operating conditions. The experiment was conducted on a four-cylinder, fourstroke, direct in jection and turbocharged diesel engine which runs with biodiesel (B50 and B100) and pure diesel. The signals of acousti...

Influence of oxygen-enrichment air intake and bioethanol–gasoline blends on exhaust emissions and fuel consumption of gasoline engine

Among human activities, motor vehicles play the most important role in air pollution. Air pollution has negative impacts on people and on the environment. In this paper the effect of oxygen-enriched air (20.8%, 21.8%, 22.8%, 23.8% and 24.8%) and different bioethanol-gasoline blends (zero, 5%, 10%, 15%, 20% and 25%) in different engine speeds (1000 rpm, 2000 rpm and 3000 rpm) on the amount o...

Sclerocarya Birrea Biodiesel as an Alternative Fuel for Compression Ignition Engines

Modeling of Compression Engines Using Biodiesel as Fuel

A single zone C.I engine model has been developed in an in-house code that would be suitable for conventional diesel as well as for alternative fuel (biodiesels), to predict the pressure and temperature variation along crank angle, work done, mean effective pressure, power output and other engine parameters suitable for biodiesel. The model has been validated with the experimental results. Perf...

Emissions Control Challenges for Compression Ignition Engines

As emission standards continue to evolve, it is clear that future engine control strategies will involve the integration of combustion optimization, fuel refinement and advanced exhaust after-treatment technologies. The West Virginia University (WVU) Center for Alternative Fuels Engines and Emissions (CAFEE) continues to engage the challenge of future regulation in a multi-pronged approach, inv...
