In this study the performance and emissions characteristics of a heavy-duty, direct injection, Compression ignition (CI) engine which is specialized in agriculture, have been investigated experimentally. For this aim, the influence of injection timing, load, engine speed on power, brake specific fuel consumption (BSFC), peak pressure (PP), nitrogen oxides (NOx), carbon dioxide (CO2), Carbon mon...

Replacing a standard piston with dome can make changes to the performance of 4 stroke combustion engine, this is due change in compression ratio being larger, thus requiring fuel that contains high octane number order get maximum results. In process researching which was originally raw convex shape, aims increase ratio, occur engine be observed from test data dyno. The results discussion or on ...

Use of an Engine Cycle Simulation to Study a Biodiesel Fueled Engine. (August 2009) Junnian Zheng, B.A., Shanghai Jiaotong University Chair of Advisory Committee: Dr. Jerald A. Caton Based on the GT-Power software, an engine cycle simulation for a biodiesel fueled direct injection compression ignition engine was developed and used to study its performance and emission characteristics. The major...

To acquire a high amount of information of the behaviour of the Homogeneous Charge Compression Ignition (HCCI) auto-ignition process, a reduced surrogate mechanism has been composed out of reduced n-heptane, iso-octane and toluene mechanisms, containing 62 reactions and 49 species. This mechanism has been validated numerically in a 0D HCCI engine code against more detailed mechanisms (inlet tem...

This paper presents a pre-mixed combustion model for diesel and Jatropha oil blends combustion studies. Jatropha oil blends are considered as a mixture of diesel and Jatropha oil. CFD package, FLUENT 6.3 is used for modeling the complex combustion phenomenon in compression ignition engine. The experiments are carried out on a single cylinder, four strokes, water cooled direct injection compress...

Biodiesel is widely known as the alternative fuel for diesel engine, but it comes with its fair share of challenges. To minimize pertinent drawbacks, additives become an essential tool and help improve renewable fuel’s properties. In this current research, biodiesel obtained from rice bran oil cotton seed oil, diethyl ether additive. Diethyl good oxygen content, high cetane number, low viscosit...

Considering the disadvantages of gasoline and natural gas as mono-fuel in SI engines has made the researchers to improve the performance and reduce the pollutant as the advantages of the application of dual fuel engines. On the other hand, lean-burn in engine may lead to the reduced pollutant. In the present study various mixtures of gasoline and natural gas with the gasoline as the dominant fu...
