Abstract: A method and apparatus for controlling a fuel injector assembly of an internal combustion engine during cold operation thereof is disclosed. If a combustion-absent condition is detected in one or more of the cylinders associated with the engine, an engine control module cuts out the affected cylinders thereby preventing additional fuel from being delivered to the cylinders for a predetermined period of time, such as 4-5 seconds. During the period of time in which the cylinders are cut out, the pistons in the remaining cylinders associated with the engine continue to operate thereby heating the engine block. After the predetermined period of time, fuel is again injected into the cylinders if a combustion-present condition is detected therein.

Abstract: The unevenness of injection rates of cylinders is reduced in a fuel supply system of a direct injection engine which uses a variable-displacement single plunger pump. The unevenness of injection rates of cylinders can be reduced by effecting a control such that the cam 100, which drives the high-pressure fuel pump 101, makes one reciprocation, while the engine makes explosions in two cylinders, and by causing the controller 55 to extend the injection time width of one of two injectors 54 which inject during one discharge of the high-pressure fuel pump and to shorten the injection time width of the other injector.

A piston having a hydraulic surface is positioned in the injector body and moveable a stroke distance between a retracted position and an advance position. At least one of the piston and injector body define a first cavity and a second cavity when the piston is located in an initial portion of its stroke distance. Before a first portion of the hydraulic surface is exposed to fluid pressure in the first cavity, and a second portion of the hydraulic surface is exposed to fluid pressure in the second cavity when the piston is in its initial portion of its stroke distance.

Abstract: A premixed charge compression ignition engine, and a control system, is provided which effectively initiates combustion by compression ignition and maintains stable combustion while achieving extremely low oxides of nitrogen emissions, good overall efficiency and acceptable combustion noise and cylinder pressures. The present engine and control system effectively controls the combustion history, that is, the time at which combustion occurs, the rate of combustion, the duration of combustion and/or the completeness of combustion, by controlling the operation of certain control variables providing temperature control, pressure control, control of the mixture's autoignition properties and equivalence ratio control. The combustion control system provides active feedback control of the combustion event and includes a sensor, e.g. pressure sensor, for detecting an engine operating condition indicative of the combustion history, e.g. the start of combustion, and generating an associated engine operating condition signal. A processor receives the signal and generates control signals based on the engine operating condition signal for controlling various engine components to control the temperature, pressure, equivalence ratio and\or autoignition properties so as to variably control the combustion history of future combustion events to achieve stable, low emission combustion in each cylinder and combustion balancing between the cylinders.

Abstract: A single needle diaphragm type carburetor has a throttle valve in a mixing passage with a venturi, an idle fuel nozzle downstream of the throttle valve when in its idle position, a high speed fuel nozzle preferably disposed within the venturi upstream of the throttle valve and a supplemental air bleed passage opening into the mixing passage upstream of both the idle and high speed fuel nozzles. Both the idle and high speed fuel nozzles communicate with each other through a transfer passage and are fed from the same fuel circuit controlled by a single needle valve which limits the fuel flow to them. At idle or low speed and low load engine operation air supplied by the supplemental air bleed passage is mixed with fuel supplied to the idle fuel nozzle. At wide open throttle, air from the air bleed passage is routed near the idle fuel nozzle, and mixed with the fuel supplied to the high speed nozzle. The air routed adjacent to the idle nozzle dries out, reduces or eliminates the liquid fuel adjacent thereto such that upon come down of the engine from wide open throttle to idle, there is not an excessive amount of fuel available to the idle nozzle which would cause an over rich come down. Advantageously, the carburetor is readily adjustable with the single needle valve and provides improved performance of the engine throughout its operational range.

Abstract: A HEUI system uses a fixed displacement, radial piston pump to provide a generally constant pump flow of high pressure hydraulic fluid over the operating speed range of the radial piston pump to minimize parasitic power drains on the engine. The radial piston pump includes an orificing suction slot to vary the pump displacement over the operating speed of the pump. A throttling valve at the pump inlet may be provided to starve inlet fluid feed if reduced flow to the injectors is additionally required.

Abstract: Pressurized injector actuation fluid, such as oil or fuel, is supplied to high pressure common rail by a fixed displacement fluid pump. Variable delivery from the pump is achieved by selectively spilling pumped fluid through a digital-acting by-pass or spill valve. The by-pass valve is actuated by a momentary electrical signal, which causes internal fluid pressure in the valve to latch it in a closed condition. The digital-acting by-pass valve permits high precision variations in the pump delivery with rapid response times. Unit pump configurations, radial pump configurations, and axial pump configurations are disclosed for both fuel injection applications and non-fuel injection applications. A single pump with plural pistons can be used to power multiple independent hydraulic systems.
