The application of biodiesel blends is known to significantly affect operation of diesel-injection equipment, especially the injectors and fuel pump. This paper summarizes experience on this subject from burning fuel blends with high-percentages of biodiesel (up to 70%) on a common-rail, high-pressure-injection diesel engine and a conventional DI engine. Both engines were unable to start after running for 100 h each and staying shut off for more than two months. In order to understand the wear characteristics of the injector nozzle, pump pistons, and elastomer parts (in the case of the high-pressure pump of the common-rail engine), due to the prolonged operation with high-percentage biodiesel blends, their injectors and pumps parts were examined and compared by performing normal photography and low magnification microscopy. Additionally, the various elastomer parts of the high-pressure fuel pump of the common-rail engine were examined for wear and deterioration. The results are compared with existing literature results from other researchers. The observed deterioration of diesel-injection equipment is caused by use of high-percentage biodiesel blends and subsequent engine shut down.

This paper presents a comparative experimental study for determining the effect of ethanol on functionality of a high pressure pump of the common rail fuel injection system. For experimental durability tests were prepared two identical fuel injection systems, which were mounted on a test bed for a fuel injection pump. One of the fuel injection systems was feed with diesel fuel; other fuel injection system was fuelled with ethanol–diesel fuel blend. A blend with 12% v/v ethanol and 88% v/v diesel fuel and low sulphur diesel fuel as a reference fuel were used in this study. To determine the effect of ethanol on the durability of the high pressure pump total fuel delivery performance and surface roughness of pump element were measured prior and after the test. Results show that the use of the ethanol–diesel blend tested produced a negative effect on the durability of the high pressure fuel pump. The wear of plungers and barrels when using ethanol–diesel fuel blend caused a decrease in fuel delivery up to 30% after 100 h of operation.

Hasan Basri-382 Indonesian warhip (KRI) use MTU 16 V 4000 M 90 diesel engine with common rail technologythat uses a High Pressure Fuel Pump. The pump has a vital function because it provides fuel up to a pressureof 1400 bars on the common rail. The problem is that there is pump compilation or damage (leakage), then thefuel pressure at the High Pressure Pump input drops and risks the output pressure of the fuel High PressurePump towards the common rail, where the pressure drops dramatically, so that the fuel pressure is below 4 baror fuel pressure inside the common rail below 700 bar Engine Control Unit (ECU) accepts the engine to stop theengine. The price of the pump is too expensive. In addition, this pump cannot be repaired or in other words itmust be replaced by the new one. Based on the pump for life, it must be replaced every 4500 hours or in onceW5 maintenanc period. But this lifetime schedule has never been approved. Therefore, it is expected to causedamage to the pump so prevention efforts can be made. In addition, the author has also used the SWOTmethod to find the best strategy in finding solutions to the problems of this High Pressure Pump. And of course,these strategies are used for advice at the end of this settlement.Keywords: Common Rail, Damage, High Pressure Pump, Parchim Class, and SWOT Method

The operation of a high-pressure, piston-plunger fuel pump oriented for use in the common rail circuit of modern diesel engines for providing fuel to the injectors is investigated in this study from a numerical perspective. Both the suction and pressurization phases of the pump stroke were simulated with the overall flow time being in the order of 12 × 10−3 s. The topology of the cavitating flow within the pump configuration was captured through the use of an equation of state implemented in the framework of a barotropic, homogeneous equilibrium model. Cavitation was found to set in within the pressure chamber as early as 0.2 × 10−3 s in the operating cycle, while the minimum liquid volume fraction detected was in the order of 60% during the second period of the valve opening. Increase in the in-cylinder pressure during the final stages of the pumping stroke leads to the collapse of the previously arisen cavitation structures and three layout locations, namely, the piston edge, the valve and valve-seat region and the outlet orifice, were identified as vulnerable to cavitation-induced erosion through the use of cavitation aggressiveness indicators.
