This paper presents comparative experimental study’s results of diesel fuel and aviation fuel effect on operational properties of a high-pressure fuel pump of a common rail injection system. The two identical fuel injection systems mounted on a test bed of the fuel injection pumps were prepared for the experimental durability tests. The lubricity properties of diesel fuel and aviation fuel (Jet-A1) were studied using the High-Frequency Reciprocating Rig (HFRR) method. The values of wear scar diameter (WSD) obtained with Jet-A1 fuels were compared to the respective values measured with the reference diesel fuel. The microscopic photographs of the wear scar diameters obtained on above mentioned fuels are presented in the paper. The test results showed that long-term (about 300 hours) using aviation fuels produced a negative effect on the durability of the high-pressure fuel pump. Due to the wear of plunger-barrel units the decrease in the fuel delivery rate occurred of about 6.7 % operating with aviation fuel. The average friction coefficients of Jet-A1 fuels were higher than that of the normal diesel fuel. Keywords: diesel fuel, aviation Jet-A1 fuel, lubricity, plunger-barrel units, wear scar diameter

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.

Experiment of fuel combustion and emission characteristics was carried on a turbocharged intercooled electronically controlled high pressure common rail diesel engine with n-butanol/diesel blends, then the results of experiment were compared and analyzed. The results show that with the adding of n-butanol, the maximum combustion pressure gradually increases and the maximum heat release rate gradually reduces; compared with diesel, CO emissions of the blends are slightly lower and decrease with the increasing load; HC emissions of the mixture fuel are higher and decrease first then increase with the increasing load; at 2000rpm, NOX emissions of the blends are a little lower than the pure diesel in small loads but higher in other loads, and increase with the adding of the load.

The article presents calculated and experimental data on changes in the power parameters of diesel engines equipped with a fuel system of various designs, on some types of fuels. Investigated: Euro diesel fuel, TS-1 kerosene, fuel mixtures with gasoline. It is shown that the power parameters of diesel engines with a "Common Rail" type battery fuel system with an electronic control unit change to a lesser extent in comparison with a traditional plunger-type high-pressure fuel pump with a mechanical regulator when switching to a more compressible and lighter fuel. The reasons for these differences in changing engine parameters are considered.

The PTC materials, as a kind of positive temperature coefficient materials, are used to heat diesel fuel in the high-pressure fuel pipe near the injector in Diesel engine, which have a lot of advantages, such as simple structure, safe and rapid heating, and fixed heating temperature around its Curie point. In order to study its heating effect on diesel fuel of the high pressure fuel pipe, the dynamical models for both the controlled object and PTC heater are presented by the way of lumped parameter, and the heating effects are also simulated and analyzed. The calculation results show that the diesel temperature is heated by the PTC materials effectively. Meanwhile, the heating law by PTC materials heating diesel fuel in the high pressure fuel pipe of engine is also summarized.

This paper presents comparative experimental study’s results of ethanol-diesel fuel blends made effects on operational properties of a high-pressure fuel pump of a common rail injection system. The two identical fuel injection systems mounted on a test bed of the fuel injection pumps were prepared for the experimental durability tests. The lubricity properties of ethanol-diesel fuel blends E10 and E20 blends were studied using a four-ball tribometer. The test results showed that long-term (about 100 hours) using of ethanol-diesel blends produced a negative effect on the durability of the high-pressure fuel pump. Due to the wear of plunger-barrel units the decrease in the fuel delivery rate occurred of about 39% after the 100 h of continuous operation with ethanol-diesel fuel blends. The average friction coefficients of ethanol-diesel fuel blend E10 was lower than that of the normal diesel fuel. After the 100 hours of operation with ethanoldiesel fuel blend E10, the measured wear scar diameter was 10% higher than that of a fossil diesel fuel.
