Abstract: A drive system for a turbocharger installed in an internal combustion engine and combined with a rotary electric machine has a generator drivable by an output power of the engine. When the rotary electric machine operates as an electric motor depending on operating conditions of the engine, the generator is driven to generate electric power that is supplied to the rotary electric machine.

Abstract: A turbocharger drive system associated with an internal combustion engine includes a plurality of turbochargers drivable by exhaust gases from the engine, a plurality or rotary electric machines mounted on the rotatable shafts, respectively, of the turbochargers and operable as electric motors or generators, and a single rotary electric machine coupled to the rotatable shaft of the engine. When the engine rotates at a low speed and under a high load, the rotary electric machine coupled to the engine shaft operates as an electric generator to generate electric power to drive the rotary electric machines mounted on the turbocharger shafts as electric motors, so that the boost pressure is increased to increase the output power of the engine. As the temperature in the combustion chambers rises because of the increased output power of the engine, the timing for supplying fuel into the combustion chambers is delayed to normalize the timing to start burning fuel, which would otherwise be advanced.

Abstract: An apparatus for controlling a valve driven by electromagnetic force is adapted to sense the amount of bounce of a valve when the valve is seated, whereby a force in the valve seating direction is applied to the valve immediately after it is seated, thereby controlling the bounce force in accurate fashion. The apparatus is provided with memory means for storing the driving force applied by drive control means, and arithmetic means for deciding, in accordance with the driving force stored in the memory, a force acting in the valve lifting direction until immediately before the valve is seated, and a force immediately after the valve is seated. Control of driving force conforming to conditions such as engine rotation is thus learned so that the proper deceleration control can be performed at all times.

Abstract: The electric power generated by an AC generator coupled to the output shaft of an engine is rectified into DC power that is then converted to AC power, which is supplied to drive a motor connected to a wheel. Dependent on the depth to which an accelerator pedal is depresed, the electric power supplied to the motor is controlled to control the speed of travel of a motor vehicle. When the motor is subjected to regenerative braking, the motor operates as a generator to produce electric power which is stored in a battery.

Abstract: An igniting device for an engine has a glow plug disposed in a combustion chamber which is constructed of a thermally insulating material.

Abstract: A control system for keeping hot the interior of a heating container on a motor vehicle supplies the heating container with hot air to which heat of a gas produced by burning fuel in a burner has been transferred by a heat exchanger. The control system has a container air temperature sensor for detecting the temperature in the heating container, an ambient air temperature sensor, and a door movement sensor for detecting whether a door of the heating container is opened or closed. When the temperature in the heating container is low and the door of the heating container is opened, the rate of fuel supplied by a fuel pump to the burner and the rate of hot air supplied by a blower to the heating container are controlled depending on the temperature of ambient air.

Abstract: An electromagnetic valve control system includes electromagnets having fixed magnetic poles facing opposite end surfaces of a reciprocally movable magnetic plate which is coupled to each of intake and exhaust valves. The intake and exhaust valves can be opened and closed under electromagnetic attractive forces produced by energizing the electromagnets. When the rotational speed of an engine incorporating the electromagnetic valve control system is lower than a predetermined speed, the intake and exhaust valves are opened and closed at a timing close to the top dead center and the bottom dead center of an engine cylinder associated with the intake and exhaust valves. The speeds of flow of intake air and exhaust gases are detected, and when the rotational speed of the engine is higher than the predetermined speed, the timing of closing the intake and exhaust valves is modified such that the intake and exhaust valves will be closed at the time the speeds of flow of intake air and exhaust gases become zero.

Abstract: A valve control system for controlling intake and exhaust valves of an internal combustion engine associated with an exhaust brake includes electromagnetic actuator means for electromagnetically operating the intake and exhaust valves. When the exhaust brake is applied, the electromagnetic actuator means is operated to increase the force to close the exhaust valve of the cylinder in the intake stroke. With the exhaust valve thus securely closed, the back pressure of exhaust gases on the engine can be increased thereby to increase the power of the engine brake being applied.

Abstract: This invention provides a bearing structure of a rotary machine wherein a shaft is supported on housings through rolling bearings made of a ceramic material, solid lubricants made of a powder lubricant of CaF.sub.2, Cr.sub.2 O.sub.3, etc., are disposed adjacent to and on both sides of the rolling bearings and seal rings are disposed between the shaft and the housings and on the sides of the solid lubricants. In a ultra-high speed rotary machine, this structure provides a bearing which is excellent in heat-resistance, deformation resistance, wear resistance and durability. The temperature of the bearing structure is raised as a whole to a high temperature without cooling the housings to provide solid lubrication by the solid lubricants, and to reduce drastically frictional resistance. The frictional resistance is further reduced under a high temperature condition to attain low friction and to drastically reduce the wear quantity of the bearing.

Abstract: A high-speed motor/generator drivable by a turbine includes a rotor mounted on the shaft of the turbine. Since the magnetic flux produced by the magnet of the rotor vary at a high frequency, a ferrite core of good high frequency characteristics is employed as a stator core confronting the rotor to reduce a high-frequency loss. To improve the flux density and magnetic permeability of the ferrite core (which one poorer than those of a core of silicon steel plates), the magnet of the rotor has a number of magnetic poles to increase the frequency at which the magnetic flux is varied, so that the electromotive force produced is increased.

Abstract: The upper parts of the cylinder liners and the cylinder head are formed integral in one piece, and a water jacket is provided around the outer peripheries of the upper parts of the cylinder walls, with no water jacket provided to the cylinder body. This eliminates the use of the core for the water jacket in molding the cylinder body, which in turn reduces the engine weight, brings about a significant cost reduction and makes machining operations easy. Because the piston head is made of a heat insulating material and a water jacket is not provided to the cylinder body, the heat is prevented from flowing down to the cylinder liners. Furthermore, the cylinder liners are made of a ceramic material to improve an anti-galling characteristic during sliding motions at high temperatures. Also, since the water jacket is provided only to the cylinder head, the water jacket can be made simple and small in structure, reducing the cooling water flow resistance.

Abstract: A device for controlling a turbocharger with a rotary electric machine detects, at all times, the rotational speed of an engine of a motor vehicle and an amount of depression of the accelerator pedal to monitor present running conditions of the motor vehicle. A required boost pressure subject to the running conditions is determined, and if a difference between the required boost pressure and a present boost pressure is greater than a prescribed value, the device determines that the motor vehicle is running under conditions which require quick acceleration. The device then drives the rotary electric machine coupled to the rotatable shaft of the turbocharger as a motor to increase the speed of rotation of the turbocharger for a quick buildup of the boost pressure.

Abstract: In the air circulation system for thermostatic chamber, a plurality of circulation ports are provided in the thermostatic chamber near the door and an intake port is formed in the wall of the chamber opposite the door. A plurality of air shutters installed in air ducts are controlled to be opened and closed in response to the opening and closing of the door. Control of various components of the system is performed as follows. When the door is open, hot air is blown out from the circulation ports on one side of the chamber and then drawn into the circulation ports on the other side, thus forming a powerful air curtain at the door portion of the chamber. When the door is closed, the hot air is blown out from the circulation ports on both sides of the chamber into the thermostatic chamber and then drawn into the intake port. In this way the hot air is circulated to keep the interior of the chamber warm.

Abstract: A control system for an internal combustion engine having a turbocharger determines an amount of air commensurate with an amount of fuel to be supplied which corresponds to the degree of depression of an accelerator pedal, based on the rotational speed of the engine and the degree of depression of the accelerator pedal. If a value produced by subtracting an amount of air downstream of a throttle valve from the commensurate amount of air is larger than a predetermined value, than an electric rotary machine combined with the turbocharger is operated as a motor to increase the amount of air supplied to the engine, and an amount of fuel corresponding to the supplied amount of air is supplied to the engine.

Abstract: An apparatus for controlling the combustion in a heater detects the temperature in a burner and selects a re-ignition mode for fuel dependent on the temperature in the burner.
