Abstract:

Recently, there has been automotive-industry-wide impetus to reduce the overall diesel vehicle emissions and the fuel consumption by increasing the fuel injection pressure within common-rail systems. Many production fuel injection systems are now capable of delivering rail pressures of 1800–2000 bar, with those able to achieve 3000 bar under development. In addition, there has been a gradual increase in the permitted fatty acid methyl ester content in EN 590 diesel from 5% to 7% with further increases to 10% proposed. With these changes, there has been mounting speculation that increasing the

Abstract:

GT-Suite software is used to establish the simulation model of high-pressure fuel injection system for diesel engine. Simulation parameters are modified based on the comparison with given experimental results. In order to improve diesel engine fuel injection performance, the cam profile was improved to ensure a high injection pressure and smooth operating characteristics. A more reasonable fuel cam profile was designed by analyzing the injection characteristics and dynamics. It improves the fuel mixture formation and combustion, so diesel economy and emissions performance are also guaranteed.

Abstract:

The objective of this investigation was to characterize the high-pressure vaporization processes of engine fuels, which are too complex in composition to be described with conventional methods. To do so a comprehensive model was developed for the transient vaporization process of droplets of practical engine fuels using continuous thermodynamics in which high-pressure effects are fully considered. Transport equations are derived in a spherical coordinate system for the semi-continuous systems of both gas and liquid phases. A general treatment of vapor-liquid equilibrium is presented, which can

Abstract:

This paper deals with the multicomponent nature of gas turbine fuels under high-pressure conditions. The study is motivated by the consideration that the droplet submodels that are currently employed in spray codes for predicting gas turbine combustor flows do not adequately incorporate the multicomponent fuel and high-pressure effects. The quasi-steady multicomponent droplet model has been employed to investigate conditions under which the vaporization behavior of a multicomponent fuel droplet can be represented by a surrogate pure fuel droplet. The physical system considered is that of a mul

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 differenc

Abstract:

The effects of high-pressure and low-pressure exhaust gas recirculation on engine and turbocharger performance were investigated in a turbocharged gasoline direct injection engine. Some performances, such as engine combustion, fuel consumption, intake and exhaust, and turbocharger operating conditions, were compared at wide open throttle and partial load with the high-pressure and low-pressure exhaust gas recirculation systems. The reasons for these changes are analyzed. The results showed EGR system of gasoline engine could optimize the cylinder combustion, reduce pumping mean effective press

Abstract:

In this paper, the high-pressure common rail system of the marine diesel engine is taken as case study to establish a real-time simulation model of the high-pressure common rail system that can be used as the controlled object of the control system. On the premise of ensuring accuracy, the real-time simulation should also respond quickly to instructions issued by the control system. The development of the real-time simulation is based on the modular modeling method, and the high-pressure common rail system is divided into submodels, including the high-pressure oil pump, common rail tube, injec

Abstract:

Majority of modern diesel engines is fitted with common-rail (CR) fuel systems. In these systems, the injectors are supplied with fuel under high pressure from the fuel rail (accumulator). Dynamic changes of pressure in the fuel rail are caused by the phenomena occurring during the fuel injection into the cylinders and the fuel supply to the fuel rail through the high-pressure fuel pump. Any change in this process results in a change in the course of pressure in the fuel rail, which, upon mathematical processing of the fuel pressure signal, allows identification of the malfunction of the pump

Abstract:

As fuel injection pressures keep rising, questions focus on additional benefits to be gained from the considerable efforts to achieve and handle the fuel pressure increments. The aim of fuel injection processes is to support the mixing of fuel molecules with oxygen. The steps towards this goal include fuel atomization, evaporation, heat transfer from air into the liquid or vaporized fuel together with transport of fuel for best air utilization. Engineering degrees of freedom include the parameters of the fuel injection system and handling of in-cylinder gas conditions. The paper describes basi

Abstract:

Variations in high pressure common rail (HPCR) system characteristic parameters influence injection characteristics and lead to fluctuation of fuel injection quantity (FIQ). The fuel injection quantity fluctuation (FIQF) has adverse affects both on coherence and stability of HPCR system. Numerical simulation model of HPCR has been developed and its accuracy has been validated by experimental results. Influence law and generation mechanism of FIQF caused by variations of different parameters such as fuel return pressure, solenoid reset force, control valve lift, fuel return orifice (A orifice)

Abstract:

Various hopping robots use the different methods to release energy for hop. The use of fuel with oxidant can provide enough potential energy for hopping by combustion. The fuel control system for combustion type hopping robot is presented. Maximum power of explosion can be obtained for high hop by mixing, fuel & oxidant in correct amount of ratio. The feedback fuel control system is presented which adjusts the ratio of fuel and oxidant to generate the desired pressure inside cylinder by controlling the fuel & oxidant pressures individually. The mixing process of fuel and oxidant takes
