Abstract
The use of biodiesel-diesel blends is a current solution to some important problems, such as the depletion of oil resources, global warming, and the pollutant emissions of smoke, carbon monoxide, and hydrocarbons of diesel engines. However, the use of this alternative fuel is characterized by a reduction in engine effective power and an increase in brake-specific fuel consumption and nitrogen oxide pollutant emissions. Using the AVL MCC zero-dimensional combustion model of the AVL BOOST simulation program, it was evaluated to what extent split injection strategies can improve the performance and fuel economy of a tractor diesel engine fuelled with biodiesel B20 at maximum brake torque condition considering noise and pollutant emissions limitation. Various pilot – main – post split injection strategies have been studied to establish the optimal injection characteristics in terms of performance and fuel economy. Subsequently, they have been adapted in terms of compliance with current emission standards. In this way, it has been emphasized that the split injection solution is a viable way to improve performance, economy, and pollutant emissions of a tractor diesel engine.
Highlights
The depletion of oil resources, global warming, and the harmful effects caused by pollutant emissions as nitrogen oxides (NOx) and soot on the environment have led researchers to find solutions to overcome these problems.Biodiesel is a fuel obtained by transesterification processes of animal or vegetable oils
Regarding the calibration step of the single injection strategy, it may be emphasised that the relative deviations of engine performance, pollutant emissions, and peak pressure (ε ) considered relevant for simulation rest under 3% for both fuels
The use of a one-dimensional simulation model developed under AVL BOOST software allows the evaluation of the performance, efficiency, and pollutant emissions of a diesel engine when using various injection strategies with minimal computation resource consumption;
Summary
Biodiesel is a fuel obtained by transesterification processes of animal or vegetable oils. The use of vegetable oils in the process of biodiesel production and its subsequent use in blend with diesel as fuel for the compression ignition engines is an effective solution to combat the global warming phenomenon.
