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 effect of variable water injection timing on performance and emission characteristics of hydrogen fueled compression ignition (HFCI) engine has been investigated and the results are presented in this paper. In this study, water is injected from 20°BTDC to 20°ATDC with injection duration of...

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...

Smoke from fire is a local, regional and often international issue that is growing in complexity as competition for airshed resources increases. BlueSky is a smoke modeling framework designed to help address this problem by enabling simulations of the cumulative smoke impacts from fires...

Recent soil and crop management technologies have potential for mitigating greenhouse gas emissions; however, these management strategies must be profitable if they are to be adopted by producers. The economic feasibility of reducing net greenhouse gas emissions in irrigated cropping systems was...

Currently the use of motor gasoline from year to year increase. In 2010 the number of vehicles in Indonesia about 26,706,705 vehicles, in 2011 amounted to 30,769,093 vehicles and 2012 amounted to 38,156,278 vehicles. This resulted in the consumption of petroleum fuels and exhaust emissions in...

More knowledge on combustion of agricultural crops is needed because of increased interest in using farm-grown biomass for energy production purposes. Presently, uncertainty regarding fuel quality and combustion-related emissions hinders the sustainable development of the agricultural biomass...
