This paper describes the use of bio-oil derived from the pyrolysis of waste wood in a single cylinder, air cooled, direct injection (DI), diesel engine developing power of 4.4 kW at 1500 rpm used in agricultural and standby applications. The combustion, performance and emission characteristics of the diesel engine fueled with three different emulsions made from wood pyrolysis oil (WPO) and Jatropha...
In this paper, a novel biodiesel named rapeseed oil monoester of ethylene glycol monomethyl ether has been developed, which has one more ester group than traditional biodiesel. It was synthesized and structurally identified through FT-IR, 1H NMR analyses. Engine test results show that when atested diesel engine is fueled with this biodiesel in place of 0#diesel fuel, engine-out smoke emissions can...
Biodiesel is renewable and environmental friendly alternative diesel fuel for diesel engine. It can be produced from food grade vegetable oils, inedible oil, animal fats and waste or used vegetable oils, by transesterification process. Transesterification is a chemical reaction in which vegetable oils and animal fats are reacted with alcohol in the presence of a catalyst. The products of reaction...
As a substitute for conventional diesel, biodiesel has received considerable attention in many countries. To investigate the emissions of an engine by experiment is time-consuming and costly, so a lot of mathematical models are used to predict the emissions of engines. A back propagation (BP) neural network was used to establish an emission model of the diesel engine fueled with biodiesel The results...
This paper analyzed chemical and physical properties of diesel fuel and biodiesel. The influence of B20, B50, B100 and 0# diesel fuel mixture on diesel engine performance has been studied in a HF495Q3 engine. Test results show that the driving force of the engine is weaker with the adding of methanol, miximum power, miximum torque reduced about 9.8%, 5.6%; For better evaluated engine economic, in...
The autoignition of methyl butanoate has been studied at 1 and 4 atm in a shock tube over the temperature range 1250–1760 K at equivalence ratios of 1.5, 1.0, 0.5, and 0.25 at fuel concentrations of 1.0 and 1.5%. These measurements are complemented by autoignition data from a rapid compression machine over the temperature range 640–949 K at compressed gas pressures of 10, 20, and 40 atm and at varying...
