摘要： A window heating apparatus for use with an automotive vheicle including a vehicle battery, an internal combustion engine, a transmission, and a generator for generating an output voltage corresponding to engine speed. A voltage regulator is switchably connected to the vehicle battery and, when connected, controls current to the field winding to maintain a constant generator output voltage. A heating element is provided for heating a vehicle window when connected to the generator output terminals. A signal indicative of a demand for heating the vehicle window and a signal indicating when the transmission is in neutral or park are provided. A circuit normally connects the generator output terminal to the vehicle battery and the voltage generator. The circuit, in response to a command signal, connects the generator output terminal to the element while disconnecting the generator output terminal from the vehicle battery and the voltage regulator. The command signal, which is produced in response to the vehicle window heating demand signal, is interrupted except when the transmission is in neutral or park to avoid excessive voltage which might damage the heating element. While the command signal is present, engine idling speed is controlled to change the generator output voltage delivered to the heater element, dependent on vehicle-compartment temperature. Also while the command signal is present, current to the field winding is interrupted if the generator output voltage exceeds a predeterminedd value.

摘要： A compression control system for an internal combustion engine for preventing the engine from knocking and for improving starting characteristics including an air/fuel mixture feedback circuit for feeding some of an air/fuel mixture in an engine combustion chamber back to the intake duct at a controlled rate. The feedback rate of the air/fuel mixture is determined on the basis of the engine operational condition and is controlled by a compression control valve inserted in the feedback circuit. The compression control valve is associated with a controller which detects the engine operating condition and determines the open period of the compression control valve in accordance with the engine operating condition. The controller also detects the engine operational position in the engine revolution cycle to synchronize the operation of the compression control valve with the engine revolution so that the compression control valve is opened for the controlled duration during the compression stroke of the engine.

摘要： A supercharge pressure control apparatus having a plurality of detectors, a control valve for controlling the exhaust gas flow flowing into an exhaust gas turbine, first and second electromagnetic valves for selectively controlling the control valve in response to control signals, and an electronic control unit for controlling the first and second electromagnetic valves in accordance with operating conditions of the engine. The opening of the control valve is compulsorily opened to a predetermined opened condition when the vehicle is in the idling condition or it is running at low speed below a preset vehicle speed through the second electromagnetic valve, while maintaining supercharge pressure control by the control valve through the first electromagnetic valve when the actual vehicle speed is above the preset vehicle speed. Excessive increase in engine speed during no load conditions or an idling condition of the engine can be prevented, while a sufficient output power can be obtained at the initial period of a suddenly accelerated condition of the vehicle without excessive reduction of the exhaust gas flow rate.

The cylinder assembly generally comprises a cylinder block formed therein a plurality of engine cylinder in line, and a cylinder head sealingly mounted on the cylinder block. The coolant circulating system comprises a coolant chamber formed within the cylinder block so that it surrounds substantial part of each engine cylinder, a return passage formed in the cylinder head. The coolant chamber communicates with the return passage through a plurality of vertical passages. Adjacent the top of the vertical passage, there is provided with a projecting portion inwardly projecting thereto. A sloped passage is formed within a partition disposed between each of adjacent engine cylinder. The upper end of the sloped passage is opened at the projecting portion at right angle to the planar surface of the projecting portion. By forming the projecting portion within the vertical passage and forming the sloped passage extending therefrom at right angle, it makes easy to form the sloped passage within the partition. Further, by forming the sloped passage as the manner mentioned above, the cylinder assembly is easily prevented from leakage of coolant and/or air/fuel mixture discharged to the engine cylinder.
