Abstract: A fuel injection pump system specifically designed to provide a variety of fuels, including aviation kerosene-jet fuel, arctic fuels and diesel fuels to a single cylinder compression ignited engine using a single bore fuel injection pump and governor in a single housing. The fuel injection pump system includes a housing enclosing a fuel injection pump with governor system which is attached directly to the engine casing thereby using the engine's oil for lubrication of the fuel injection pump. The internally attached governor system enables the engine to idle smoothly at a predetermined speed and also provide high-speed protection by reducing fuel at predetermined RPM settings. A uniquely designed plunger and barrel in the fuel injection pump incorporates an anti-knock helix shaped plunger that changes the idle injection timing for sound attenuation.

Abstract: The present driving apparatus comprises a torque motor 10 as a driving source, and a gear train which transmits rotation of a motor shaft 1 of the torque motor 10 to a driven shaft 13, wherein the gear train comprises a non-circular driving gear 11 which is attached to the motor shaft 1 and a non-circular driven gear 12 which is attached to the driven shaft 13 and engaged with the non-circular driving gear 11. When the motor shaft 1 rotates by supplying electric power to the torque motor 10, the rotation is transmitted to the non-circular driven gear 12 via the non-circular driving gear 11, so that the driven shaft rotates. Here, the torque of the torque motor 10 is transmitted to the driven gear while it is increased or decreased in accordance with rotating positions. In this manner, the driving apparatus with a torque motor can provide desired torque at any rotating positions.

Abstract: A signal-processing apparatus has a digital filter for processing input data from a knock-sensor. The digital filter is designed as an FIR filter characterized by filter coefficients that are equal to values of mince points 0 to 16 obtained based on a reference waveform. The reference waveform is created by concatenating half waves of a first sinusoidal waveform with half waves of a second sinusoidal waveform with peak values equal to half the peak value of the first sinusoidal waveform. The values of mince points 4, 8 and 12 are 0. Each value of mince points 1, 3, 13 and 15 is equal to corresponding value of mince points 5, 7, 9 and 11. The digital filter effectively reduces a filter-processing load.

Abstract: A rotor of a crankshaft has protrusions. A timing sensor produces a rotation leading signal and a rotation trailing signal. A control unit measures a previous signal production interval and a present signal production interval based on the rotation signals, and determines that the rotor is in the forward rotation if an inequality of Tn/Tn−1≧K holds alternately but consecutively by four times on the side of the rotation trailing signal. As a result, at the time of manufacturing the rotor, the degree of freedom of design in the positional relations of the protrusions can be enhanced to control the ignition timing precisely and stably.

Abstract: A fuel injection system operates under a substantially constant pump speed and creates multi-pressure levels by diverting the fuel flow. Fuel pressure can be switched from one steady pressure level to another level on-demand instantly. This superimposes and overlaps typical fuel injection events in the linear operating ranges under different pressure levels, significantly increasing the fuel injection dynamic range. Lower fuel injection when idle or during city driving reduces fuel consumption per mile traveled and reduces exhaust emission that causes smog in metropolitan areas. The system delivers additional power to the engine instantly at peak load on-demand, reduces idle speed with the engine running smoothly, does not change fuel tank temperature, and may enhance the life of the fuel pump.

Abstract: An internal combustion engine is provided with a VVT mechanism capable of adjusting overlap period in which both intake and exhaust valves are open. The internal combustion engine is also provided with a recirculation mechanism that recirculates exhaust gas to the intake side. An EGR map from which internal EGR amount based on the VVT mechanism and external EGR amount based on the recirculation mechanism are derived in accordance with engine speed and engine torque is prepared.

By performing EGR control in consideration of these parameters, the occurrence of knocking during EGR control can be suppressed, and an improvement in fuel consumption and the like can be achieved with certainty.

Abstract: A generic technique for the detection of air-fuel ratio or torque imbalances in a three-cylinder engine equipped with either a current production oxygen sensor or a wide-range A/F sensor, or a crankshaft torque sensor, is disclosed. The method is based on a frequency-domain characterization of pattern of imbalances and its geometric decomposition into two basic templates. Once the contribution of each basic template to the overall imbalances is computed, templates of same magnitude of imbalances but of opposite direction are imposed to restore air-fuel ratio (or torque) balance among cylinders. At any desired operating condition, elimination of imbalances is achieved within few engine cycles. The method is applicable to current and future engine technologies with variable valve-actuation, fuel injectors and/or individual spark control.

Abstract: In a combustion engine, the fuel quantity is determined as a function of the inflowing air mass. As a measure for the inflowing air mass, one uses either a main load signal, which is generated by an air-mass flow sensor and represents a measure of the inflowing air mass, or a secondary load signal, which is generated as a function of the degree of throttle of a throttle device in the intake port and of the speed of the combustion engine, to correct the secondary load signal, an air-mass compensation quantity being utilized. The air-mass compensation quantity is generated in operating phases in which the correctness of the main load signal may be assumed, by comparing the main load signal with the secondary load signal.

Abstract: A product fill system and method uses a mode valve. The mode valve is a shuttle valve that allows the shock tube to communicate with the filler valve during a fill operation corresponding to fill mode of the mode valve. If the filler valve is shut off, any overpressure can pass through the mode valve and be absorbed by the shock tube. The mode valve can be switched into a clean mode in which the shock tube is connected more directly in the circuit between the upstream side of the mode valve and the filler valve. In other words, the shock tube is on a side circuit of the main circuit used for product feeding during the fill operation. However, during the clean operation, the shock tube is in the circuit such that cleaning material travels completely throughout the shock tube. The method of the present invention involves the use of the product fill system so as to accommodate cleaning without disassembly of parts.

Abstract: A diaphragm head with a high energy content of the oil space (pressure×volume) has a strong negative influence on the corresponding behavior of the oil overflow valve. The reaction of the valve leads to an undesirable increase in the opening time by which more oil is discharged than oil introduced by means of a compensation pump. This has the result that after multiple strokes the diaphragm is not driven to its dead position. With this, all of the compressed gas is not expelled which is accompanied by a rapid decrease of the suction capacity.

First, push the manual opening unit to move the valve plate of the electromagnetic valve forward a certain distance, then the electrically controlled blocking unit moves the valve plate further according to a danger removal signal provided by a judgment device. The electromagnetic valve is not opened completely until these two movements are operated, thereby, it can prevent the blocked valve from opening intentionally during an unsafe situation.
