The method of supplying fuel for an electronic-controlled fuel injection system is calculating the required fuel amounts under various operating conditions of engine and controlling the opening and closing timing of fuel injection. After fuel injection, the effects of condensation and atomization of injected fuel as well as fuel mixing for combustion are strongly dominated by the opening timing and duration of intake valves. This can further affect the emission composition and performance for an engine. As the emission regulation is getting more stringent and the requirement for minimizing specific fuel consumption is becoming more urgent, investigating the effect of closing timing of fuel injection has turned out to be a major issue. Therefore, this paper presents a study about a series of engine tests to investigate the effect of end of injection angle on the performance and emission formation for a gasoline engine. In these tests, the values of end of injection angle are adjusted using a control software for electronic-controlled fuel injection system so that the results can be analyzed under various engine speeds and loads.

Fuel injection system is an indispensible part of the present day automobiles. The depletion of the fuels along with continuous surge in the fuel prices has made it imperative to use fuel economically and restricting the wastage to a minimum. Contrary to the carburetor, using predefined amount of fuel irrespective of the environment, Fuel Injection System uses just the required amount of fuel based on the operating conditions as sensed by the Engine Control Module (ECM). Numerous parameters are required to be sensed by the ECM to achieve optimum efficiency of the engine. To handle the processing of such large number of parameters, a robust architecture is required. This paper presents the design and implementation of ECM utilized in Electronic Fuel Injection (EFI) system on a Field Programmable Gate Array. The ECM architecture discussed in the proposed system is computationally efficient enough to fulfill ever-increasing functionalities of the ECM. The main objective of this research is to sense the parameters required for the ECM analysis and to interpret and analyze this data and accordingly control the solenoid (actuator). The CAN controller is also deployed in an FPGA to facilitate the communication between ECM and Human Machine Interface (HMI) to indicate the parameters sensed by the sensor on the LCD. The target device (FPGA) for this work is Xilinx Spartan 3E and the design tool is Xilinx ISE 14.7 with the ECM and CAN controller being modeled in Verilog Hardware Description Language (HDL).

Experiments have been completed to characterize coal-water slurry sprays from a modified positive displacement fuel injection system of a diesel engine. The injection system includes an injection jerk pump driven by an electric motor, a specially designed diaphragm to separate the abrasive coal from the pump, and a single-hole fuel nozzle. The sprays were injected into a pressurized chamber equipped with windows. High speed movies and instantaneous fuel line pressures were obtained. For injection pressures of order 30 MPa or higher, the sprays were similar for coal-water slurry, diesel fuel, and water. The time until the center core of the spray broke up (break-up time) was determined both from the movies and from a model using the fuel line pressures. Results from these two independent procedures were in good agreement. For the base conditions, the break-up time was 0.58 and 0.50 ms for coal-water slurry and diesel fuel, respectively. The break-up times increased with increasing nozzle orifice size and with decreasing chamber density. The break-up time was not a function of coal loading for coal loadings up to 53 percent. Cone angles of the sprays were dependent on the operating conditions and fluid, as well as on the time and location of the measurement. For one set of cases studied, the time-averaged cone angle was 15.9 and 16.3 deg for coal-water slurry and diesel fuel, respectively.

Cavitation erosion has long been recognized as a potential problem in the components and piping of diesel engine fuel injection systems. Specific cavitation erosion problems have been experienced recently in the fuel injection systems of the Colt-Pielstick PC2 engines of the Great Lakes bulk carriers MV James R. Barker, MV Mesabi Miner, and MV William J. De Lancey. Similar damage has been found in the injection systems of PC2 engines onboard other U.S.-flag vessels. The experience on the subject vessels and the efforts being taken to eliminate or minimize these problems are described. The modeling and methods used in a digital computer simulation of the fuel injection system on these vessels are presented. This simulation is being developed to study the effects of the delivery valve spring characteristics and performance, system pressures, and various system details and potential modifications on the overall performance of the fuel injection system. Special emphasis has been placed upon the factors which can be causing the cavitation damage within the high-pressure injection piping and injector bodies. Example simulation results are presented. The simulation will provide a practical and economical way to evaluate potential modifications.
