  • Patent number: 5899183
    Abstract: According to the present invention, when a vehicle speed is less than a set value (e.g., 40 km/h) and a throttle opening degree is more than a set value, it is determined that the vehicle is accelerating, and a viscous clutch is turned off. Therefore, a shearing operation of high-viscosity fluid by a rotor of a viscous heater is not performed. In this way, a driving load applied to an engine is reduced, so that an accelerating state suitable for an intention of a driver can be obtained. Further, when the vehicle speed is more than a set value (e.g., 40 km/h) and an engine rotational speed is more than a set value (e.g., 3500 r.p.m.), the viscous clutch is turned off, and a driving load applied to the engine and a V-belt is reduced.

  • Patent number: 5429082
    Abstract: A method and arrangement for operating a drive for auxiliary devices arranged on an internal-combustion engine has a differential gear driven by the crankshaft of an internal-combustion engine distributes a driving torque corresponding to the tooth numbers of the transmission to auxiliary devices driven by this transmission. An exciting current which is supplied to an auxiliary device, as a function of load signals and/or cooling water temperature signals, is regulated so that it changes the driving torque of the generator. For maintaining a constant wiring voltage generated by the generator, the rotational speed of the generator therefore changes and, via the differential gear, the rotational speed changes of another auxiliary device. The cooling power of the internal-combustion engine can therefore be regulated as a function of cooling demands or load requirements.

  • Patent number: 5228305
    Abstract: A user-adjustable control system monitors an electrical signal indicative of manifold pressure in an internal combustion engine that powers a wheeled vehicle. The engine simultaneously powers the drive train of the vehicle and, when a thermostat so dictates, an air conditioning compressor. This system improves vehicle driving performance by selectively restricting the diversion of engine power from the drive train to operate the air conditioning compressor, based on threshold changes in a monitored electrical signal. With electronic circuitry the system selectively disengages power to the compressor when the difference between manifold and atmospheric pressure drops below a preset value. The system includes a transducer connected to provide an electrical output signal that is indicative of pressure changes in the engine manifold. The manifold pressure changes are, in turn, indicative of changes in the engine's load conditions.

  • Patent number: 5197427
    Abstract: In a V-type engine with two bore-offset banks opposed to one another at a predetermined angle, an accessory mechanism is provided between the two banks. A drive belt for the accessory mechanism is disposed on the side of one of the banks which is recessed inwardly due to the bore offset. In another embodiment, the accessory mechanism is a supercharger driven by a balancing shaft which, in turn, is driven by the crank shaft. In yet another embodiment, the V-type engine has a separate timing belt for each bank, that is, a first timing belt for the bank which is recessed inward because of the bore offset, and a second timing belt for the bank which juts out because of the bore offset. A drive belt is provided for driving the supercharger. The belts are arranged in the following order from the inside outward: the second timing belt, the first timing belt and the accessory belt.

  • Patent number: 5188072
    Abstract: The fuel pump permits a high delivery pressure with a low degree of pressure fluctuations and can be attached to the internal-combustion engine in a space-saving manner in axial prolongation of the camshaft and can be driven in a simple fashion. In an alternative embodiment of the invention, the fuel pump serves as a tensioning device for a belt or chain drive by virtue of the drive wheel of the fuel pump acting as a belt or chain tensioning roller.

  • Patent number: 5161490
    Abstract: An air-cooled internal combustion engine and a structure of its air cleaner, a major object of which is to control noises emitted from various parts of engine and to minimize the overall size and dimensions of the engine. A cam shaft and a balancing shaft are arranged on an air cleaner side relative to a crank-shaft, a starting motor is arranged on an exhaust muffler side relative to the crank-shaft, shaft portions of the balancing shaft and the starting motor are located at a position lower than the crank shaft, and the exhaust muffler is arranged vertically above the starting motor, so that a center of gravity of the entire engine is lowered and engine noise can be controlled. Further, noises emitted from various parts of engine are controlled by positioning and shaping of an exhaust pipe, a shape of a cylinder head cover, and an arrangement and position of a fuel tank.

  • Patent number: 5080059
    Abstract: An improved engine load management system that will de-excite the field coils of an alternator that is driven by an internal combustion engine when the battery that the alternator charges is above a required minimum voltage and when the engine is operating under high load conditions such as acceleration or climbing. When the battery charge falls below the required minimum, the system excites the alternator field coils and permits the alternator to charge the battery despite a high engine load condition. When the battery charge is above the minimum required voltage, but below the voltage at which charging is discontinued, and the engine is under high load, the alternator field coils are energized and de-energized in a cycle that reduces alternator drag on the engine, but permits limited battery charging to occur.

  • Patent number: 5063897
    Abstract: A vehicle and drive unit therefor including a transversely disposed engine located in an engine compartment. The cylinders are inclined to the rear from a vertical plane at an acute angle and the engine crankshaft drives an accessory shaft that rotates in a plane disposed at an acute angle to the vertical and forwardly of the cylinder axis and at an acute angle to the cylinder axis. Accessories are driven from this accessory shaft as are the front wheel axles which lie on the opposite side of the plane containing the cylinder axis from the output shaft axis. The accessory drive is disposed inwardly of the ends of the engine so as to provide a compact body and the engine body is recessed to receive the accessory drive so as to minimize the distance between the accessory shaft and the engine crankshaft.
