Abstract: A variable valve timing controller has a housing having a hole in its surface facing a vane rotor. A fitting ring is press-fitted into the hole. A stopper piston prevents relative rotation between the vane rotor and the housing by engaging with the fitting ring. The hole is formed with a part non-contacting with the fitting ring near a through hole, in which a camshaft is inserted, of the housing. Since the fitting ring is apart from the inner surface of the non-contacting part when the fitting ring is press-fitted, little or no stress arises around the non-contacting part near the through hole. Therefore, deformation of the through hole is prevented and sliding friction between the inner periphery of the through hole and the camshaft is minimized.

Abstract: An engine employs a dual mode combustion process including a first combustion mode for light loads utilizing premixed charge forced auto ignition (PCFA) wherein a pulse jet of reacting fuel mixture from a prechamber mixes with an ultra dilute premixed fuel-air charge in a main chamber, causing rapidly expanding combustion that ignites the remaining ultra dilute mixture by compression ignition. This improves efficiency, allows combustion phasing control and reduced NOx emissions. For higher speeds and loads, a conventional second combustion mode is utilized wherein a strong premixed mixture is ignited conventionally with spark ignition and/or pulse jet ignition. Cylinder pressures which would result from compression ignition at the higher speeds and loads are thus reduced providing overall engine operation with reduced emissions, improved fuel economy, and reduced noise through improved control of the combustion process.

Abstract: By setting the configuration of a cavity (25) of a piston (5) appropriately, tumble is produced in air that is aspirated into a combustion chamber (6) inside a cylinder (3) from an intake port (8), and by means of this tumble, the spray of fuel injected by a fuel injector (12) is caused to gather around the periphery of a spark plug (7). A predetermined tumble in the form of an upright ellipse is set in the longitudinal cross section of the cylinder (3) which includes an injection point (I) of the fuel injector (12) and an ignition point (T) of the spark plug (7). The bottom surface (26) of the cavity (25) is curved so as to conform to the radius of curvature (R1) of the lower end of the elliptical tumble, thereby advancing the formation of elliptical tumble which is unlikely to interfere with the cylinder wall surfaces.

Abstract: An electronic engine control unit for a motorcycle or other two-wheeled vehicle gradually decreases engine torque at the time of a failure so as to eliminate an uneasy feeling that an operator might experience if the engine torque were to be reduced abruptly. When a failure is detected, a throttle valve is closed gradually by initially closing the valve quickly and then slowly closing the valve so as to obtain a smooth decrease in engine torque. In addition, the ignition timing is changed gradually toward retardation to gradually decrease engine torque. Alternatively, the ignition pulses to the cylinders are thinned out gradually to cause a gradual decrease in engine torque. As a further alternative in the case of a multi-cylinder engine, the ignition pulses are stopped on a cylinder-by-cylinder basis to cause a gradual decrease in engine torque.

In the high-pressure region (3), the fluid to be triggered is at an operating pressure (p_R). This operating pressure (p_R) and an overpressure that may occur in some circumstances is recorded, because of the provision that the actuator unit (7) is embodied as a force-measuring sensor. In particular, this valve (1) serves as a pressure-limiting valve in a common rail system (Drawing).

Abstract: To prevent the sticking of the valve body of an electromagnetic valve under idling conditions or under non-injection conditions in a control device of common rail fuel injection system of an engine wherein the fuel supplied from a feed pump (6) is pressurized to high pressure by a high-pressure pump (3) and the quantity of fuel supply to this high-pressure pump (3) is adjusted by an electromagnetic valve (7) whose degree of opening is controlled in accordance with a duty signal, the control frequency of the duty signal is altered to a lower frequency (&lgr;l) when an operating condition such that the degree of opening of the electromagnetic valve (7) is constant is detected. In this way, the energy or amplitude per current wave flowing in the electromagnetic solenoid (39) can be made larger, so making it possible to produce minute vibrations of the valve body (41). Sticking of the valve body (41) can thereby be prevented.

A transfer pump 17 which supplies fuel from the second fuel sump portion 11b to the first fuel sump portion 11a is driven with a traveling energy of divergent fuel forming a portion of fuel to be supplied to the internal combustion engine from the fuel pump 12. A divergent fuel control unit 20 is disposed in a supply line of the diverged fuel to decrease the flow rate of the divergent fuel in dependence on an increase in a demanded fuel flow rate of the internal combustion engine, thereby minimizing a compensation flow rate of the fuel pump 12 as a whole and the flow rate size thereof.

Abstract: A portion of the engine cooling water flowing from the cooling water pump through the engine and the radiator back to the cooling water pump is introduced into the carburetor through piping to heat the carburetor. The downstream side of the carburetor piping is connected to by-pass piping connecting a thermostat valve provided in the radiator piping at a position downstream of the engine and the intake port of the cooling water pump. Accordingly, engine cooling water flows mainly into the by-pass piping when the thermostat valve is closed, and flows mainly into the radiator piping when the thermostat valve is opened. The carburetor is therefore heated even before the thermostat valve is opened immediately after actuation of an engine. In addition, excessive heating of the carburetor after the engine is appropriately heated is prevented without using a special switching valve.

Abstract: A band saw with a complex coordination of a tilting motion and a translational motion between the workpiece and the band saw blade, so that a curved cut is made in the workpiece. The geometric parameters of the cut can be continuously adjusted. This makes it possible to optimize a contact length of the saw blade in the workpiece, which is an important factor in the cutting process. It is thus possible to saw workpieces made of stone and similar materials that are typically difficult to cut. The cut and the contact length of the saw blade can be tailored individually to each workpiece to be sawed. Thus, workpieces of different geometrical dimensions and different material properties, in particular with different material hardnesses, can be processed using the band saw according to the invention without having to undertake significant changes.
