摘要： Embodiments for an internal combustion engine are provided. In one example, and internal combustion engine comprises at least two cylinders each including an injection nozzle and a fuel supply system for supplying the cylinders with fuel. The fuel supply system includes a supply line connecting each injection nozzle to a first fuel reservoir storing fuel at a first pressure, the first fuel reservoir filled by a pump provided upstream, a second fuel reservoir storing fuel at a second pressure less than the first pressure and connected to the first fuel reservoir via a connecting line for filling with fuel, and a bypass line connecting the second fuel reservoir to each injection nozzle. The bypass line opens into the fuel supply system downstream of the first fuel reservoir, thereby forming a connection point, and a shutoff element is arranged in the bypass line, opening or shutting off the bypass line.

摘要： A fuel system is disclosed which is adapted to improve engine ignition properties by ensuring that, when the engine ignition is turned off, residual fuel left over in the engine area after use is not returned to the fuel tank but instead remains in a common rail injector area. The fuel system for an excavator according to the present invention comprises: a fuel tank having a fuel supply line for discharging fuel and a return line for returning residual fuel after combustion in the engine area; a water-fraction separator which is provided downstream of the fuel tank, removes the water fraction contained in the fuel that is sucked in, and consists of a hand pump that is linked to the fuel supply line and of a first filter that is linked to the hand pump and filters out extraneous material in the fuel; an injection pump which is provided downstream of the water-fraction separator and which provides an injector with a high pressure supply of the fuel, from which the extraneous material has been filtered out on passing through the first filter and a second filter linked thereto, such that said fuel is sprayed into an engine combustion chamber; a fuel control unit which is respectively linked to the second filter and the injection pump and controls the injection pump so as to control the volume of fuel supplied to the injector; and a check valve which is provided in the return line and ensures that, when the equipment is made to stop working because the engine ignition is turned off, residual fuel left over in the engine area after use is not returned to the fuel tank along the return line but instead remains in the injector area.

摘要： A direct injection fuel supply system, in one exemplary implementation, includes a lift fuel pump, a positive displacement pump, at least one fuel injector and an accumulator assembly. The lift pump is adapted to be in fluid communication with a supply of fuel and the positive displacement pump is in fluid communication with and downstream of the lift pump. The at least one injector is in fluid communication with an outlet of the positive displacement pump via a high pressure fuel line. The accumulator assembly includes an accumulator and a valve, where the valve is in direct fluid communication with the high pressure fuel line and the injector. The valve is selectively controlled to at least one of an open state providing fluid communication between the accumulator and the high pressure fuel line and a closed state blocking fluid communication between the accumulator and the high pressure fuel line.

摘要： A high vapor pressure liquid fuel (e.g. LPG) injection system is provided that keeps the fuel liquid at all expected operating temperatures by use of a high pressures pump capable of at least 2.5 MPa pressures. The fuel can be injected directly into the cylinder or into the inlet manifold of an engine via axial or bottom feed injectors and also could be mixed with a low vapor pressure fuel (e.g. diesel) to be injected similarly. The fuel, mixed or unmixed, can be stored in an accumulator under high pressure assisting in keeping the engine running during fuel changeovers and injection after a period of time as in re-starting the engine. The same injectors can be used to inject any of the fuels or mixtures of them.

摘要： A fuel accumulator is provided to assist restarting a direct injection engine fuel system. The fuel accumulator includes a central guide post with a fuel passage. A cup shaped plunger with a closed end is slideably disposed on the central guide post. A seal means is disposed between the plunger and the central guide post to define a substantially sealed fuel chamber. A biasing means is provided to urge the plunger onto the central guide post. A fuel admission valve selectively prevents and permits fuel from entering and exiting the fuel accumulator. When a fuel system stop is commanded, pressurized fuel is admitted into the fuel chamber, thereby compressing the biasing means which maintains a restart pressure. When a fuel system start is commanded, pressurized fuel is expelled from the fuel accumulator.

摘要： A pulsation damper is provided between and in series with a low pressure fuel system pipe and a high pressure pump of a fuel supply system. During startup of an engine, low pressure fuel supplied via the low pressure fuel system pipe is injected from an intake passage fuel injector. When the fuel pressure is equal to or less than a fuel pressure at which good startability can be maintained, the pulsation damper closes off communication between the high pressure fuel system pipe and the low pressure fuel system pipe using the spring force of a spring.
