Rapeseed Oil Methyl Esters

Abstract The paper presents the laboratory test results determining physical parameters of fuel mixture made up of petroleum diesel oil, rapeseed oil methyl esters (up to 20%) and water (up to 2.5%). The obtained parameters prove that adding bio-components (rapeseed oil methyl esters) and water to fuel does not result in deterioration of their physical and chemical properties and are comparable to base fuel parameters, namely petroleum diesel oil. The mixture was a subject of bench testing with the use of a self-ignition engine by means of pre-catalytic fuel treatment. The treatment process consisted in fuel - catalytically active material direct contact on the atomizer body. At the comparable operational parameters for the engine, the obtained exhaust gases opacity was lower up to 60% due to the preliminary fuel mixture treatment in relation to the factory-made fuel injection system using petroleum diesel oil.

The common rail injection system has allowed torque and power performance of diesel engines to improve greatly, while reducing fuel consumption and conforming to emissions standards. This paper proposes a simple but effective energy-based model of a common rail injector as a basis for the implementation of the advanced fuel injection control strategies. The proposed model has been validated comparing the simulation results with real experimental data. The obtained results show how the dynamic behavior of the injector is well captured by the model.

The paper presents the results of the research on the uniqueness of the combustion process in the Perkins 1104D-E44TA engine already equipped with a Common Rail injection system, and then adapted on an engine test stand to dual-fuel operation. The result of the combustion process is an indicator diagram. The combustion process in the cylinder of the tested engine was evaluated by determining the uniqueness indicators of subsequent operating cycles, such as: the uniqueness indicator for the maximum pressure of the operating cycle, the uniqueness indicator for the mean indicated pressure, the uniqueness indicator for the indicated diagram and the uniqueness indicator for the partial indicator diagram. The conducted tests and the analysis of the results showed the impact of dual-fuel power supply of the tested engine on the combustion process, as compared to supplying the engine only with diesel fuel, for which it has been optimized.

Abstract The paper is aimed at studying the overall dynamic behavior of the Common Rail Injection System actually used on a 4 cylinder industrial Diesel engine. Firstly, the paper introduces the main characteristics of a lumped and distributed parameters model of the high pressure branch of an actual Common Rail System, and the main hypotheses assumed to model it using a multi-port approach code for the analysis of the dynamic response of hydraulic systems submitted to fast transients. The model of the Common Rail System is then used to study its dynamic behavior when involved in the handling of the engine injection cycle for medium values of the crankshaft regime and for different pressure levels in the Rail. The analysis is performed applying to the injectors, to the pressure control valve and to the high-pressure pump the control strategies imposed by the Electronic Central Unit (ECU), as actually implemented into an industrial ECU for Diesel engine management. The model reliability and accuracy are evidenced through a numerical vs. experimental data comparison, mainly in term of rail pressure dynamic behavior. The analysis successively outlined in the paper allows to state how the hydraulic behavior of the Common Rail System interact with the electro-hydraulic injectors dynamics, and to determine the influence of this interaction on the total injected mass per cycle.

Common rail direct fuel injection is a modern variant of direct fuel injection system for petrol and diesel engines. The common rail system prototype was developed in the late 1960s by Robert Huber of Switzerland and the technology further developed by Dr. Marco. In petrol engine MPFI technology was developed and implemented in earlier days. Basically common rail tube was fabricated by steel for petrol engines. In the current study Steel, Brass, Aluminum alloy a356 and ABS materials were analyzed separately and aluminum is found the best material among the steel, brass and ABS material for common rail injection tube. Keywords: Common Rail Injection System, Alternate Material.
