摘要： A fuel injection control apparatus for an internal combustion engine includes a low pressure fuel pump, a low pressure fuel passage, a high pressure fuel pump, a high pressure fuel passage, a fuel injection valve, a high pressure controller, and a low pressure controller. The low pressure controller calculates a feedforward correction amount that increases as a request injection amount of the fuel injection valve increases and an increase rate of the high pressure target value increases when a high pressure target value increases. The low pressure controller calculates a feedback correction amount based on a low-side pressure deviation when the high pressure target value increases. The low pressure controller controls driving of the low pressure fuel pump based on a sum of the feedforward correction amount and the feedback correction amount.

摘要： A method for operating a fuel injection system of an internal combustion engine is disclosed. The fuel injection system comprises a high pressure accumulator (rail) and a high-pressure fuel pump with a digital inlet valve and which guides fuel into the high pressure accumulator. The number of the control pulses for the digital inlet valve and thus the number of the pump delivery strokes is reduced with respect to the number of the injection steps of an injector of the injection system, in order to thereby reduce the noise and the energy consumption of the high-pressure pump.

摘要： The invention relates to a fuel injector (1) for an internal combustion engine. The fuel injector (1) is comprised of an injector body (5) with an injector tip (6). The injector tip (6) is used for the injection of fuel into the combustion chamber (4) of the internal combustion engine. For this reason, the injector tip (6) is designed so as to be at least partially extended into the combustion chamber (4). If the injector tip (6) is designed to be flush with the surface of the combustion chamber (4), the injector tip (6) is arranged so that it directly faces toward the combustion chamber (4). Furthermore, the injector tip (6) is at least partially coated with a first oxide layer (9). According to the invention, a catalytic second oxide coating (10) composed of cerium oxide (CeO2), praseodymium oxide (PrO2), zirconium oxide (ZrO2), or any bi-component combination thereof is applied on top of the first oxide coating (9). The present invention also discloses a method of producing a fuel injector (1) which is at least partially coated with a first oxide coating (9) and a second oxide coating (10) applied over the first oxide coating (9), where the second oxide coating (10) is composed of at least one or more compounds from the group comprising cerium oxide (CeO2), praseodymium oxide (PrO2), or zirconium oxide (ZrO2) and is applied as a washcoat.

摘要： A system and method is provided to analyze an intermediate pressure signal portion between an end of an injection event signal portion and a start of a subsequent injection event signal portion. The analysis is simplified by identifying a plurality of single cycle windows and calculating a single value, such as a mean or a median, for each of the windows. An intermediate portion single value is determined by averaging the single values for each of the windows. The intermediate portion single value may then be used to identify pumping events or leakage errors that occur during the intermediate pressure signal portion that affect further analysis of the intermediate pressure signal portion.

摘要： Systems and methods for sensing fuel vapor pressure are provided. In one example, a method for a vehicle comprises: during an engine start after the engine has been off for at least a minimum duration, actively controlling fuel pressure in the fuel system to a vapor-liquid volume ratio greater than zero and then recording sensed fuel pressure and temperature in the fuel system. In this way, the vapor pressure of a fuel at a given temperature may be accurately measured during isothermal conditions, thereby improving an estimation of fuel volatility.

摘要： A low leakage large bore fuel system includes a common rail fluidly connected to at least one of a source of heavy fuel oil and a source of distillate diesel fuel. A plurality of fuel injectors are fluidly connected to the common rail and each include a cooling inlet and a cooling outlet. Each fuel injector also includes an electrical actuator coupled to a direct operated nozzle check valve by a pilot valve member and a control valve member. Fuel leakage is reduced between injection events by equalizing pressures in a pilot control chamber and an intermediate control chamber that are separated by a guide surface of the control valve member. Also, between injection events the pilot valve member blocks a drain outlet from a common rail inlet of the fuel injector.

摘要： A fuel injector for an internal combustion engine is disclosed. The fuel injector includes a housing, a valve seat, a metering orifice disc, and a needle. The housing has an inlet, an outlet, and a longitudinal axis extending therethrough. The valve seat is disposed proximate the outlet and includes a passage having a sealing surface and an orifice. The metering orifice disc is located at the outlet and has a plurality of metering openings extending therethrough. The needle is reciprocally located within the housing along the longitudinal axis between a first position wherein the needle is displaced from the valve seat, allowing fuel flow past the needle, and a second position wherein the needle is biased against the valve seat, precluding fuel flow past the needle. A generally annular channel is formed between the valve seat and the metering orifice disc. The channel tapers outwardly from a large height to a smaller height toward the orifice openings. A method of generating turbulence in a fuel flow through a fuel injector is also disclosed.
