Abstract: A control apparatus for an engine includes an engine, a state quantity setting device, an injector, a spark plug, and a controller. The controller sets a G/F in a range from 18 to 50. After the spark plug ignites air-fuel mixture, unburned air-fuel mixture is combusted by autoignition.

Abstract: An internal combustion engine combusts a first fuel or a second fuel. A method for controlling the engine comprises supplying first fuel to at least one combustion chambers of the internal combustion engine, stopping the supply of the first fuel to the combustion chamber in response to an engine operating condition, and fueling with the second fuel to the at least one combustion chamber after a predetermined period, so as to maintain an engine speed within a predetermined range.

Abstract: A rear luggage compartment structure for a hatchback vehicle includes a trunk board comprising front and rear boards which is changeable between a normal position where the front and rear board are laid on front and rear parts of a rear luggage compartment floor, respectively, and a built-up position where the rear board is held upright and the front board is situated horizontally between a rear seat and the rear board held upright so as thereby to create a luggage storage space over the front board that is accessible from a passenger compartment and a secret box under the front board.

Abstract: A fuel injection control system for a direct injection-spark ignition engine determines an injection pulse width corresponding to a given quantity of fuel with which an injector is kept open, controls the injector to spray a given quantity of fuel in a compression stroke while the engine operates in a zone of lower engine loads specified for lean stratified charge combustion so that the fuel is stratified around an ignition plug to cause lean stratified charge combustion so as thereby to provide an air-fuel ratio greater than a stoichiometric air-fuel ratio, executes fuel injection feedback control to control a quantity of fuel injection based on an air-fuel ratio detected by an oxygen sensor, causes the injector to spray a given quantity of fuel through a plurality of intake stroke split injection in a specified engine operating zone in which the fuel injection feedback control is performed to maintain at least a stoichiometric air-fuel ratio while the engine operates with lower loads, learns a fuel injectio

Abstract: A door lock/unlock system of a type having an electrically operated door lock/unlock mechanism for holding a door in a locked position and allowing the door to be opened comprises a position sensor for detecting positions of the door lock/unlock mechanism, namely a lock position and an unlock position, when a battery is removed from an electric circuit once and thereafter re-connected again to the same, with or without an intention of committing a theft of the vehicle, and a controller for controlling operation of the door lock/unlock mechanism according to the detected position.

Abstract: A suspension system of a vehicle which judges the direction of a damping force of a shock absorber of damping force characteristic variable type, provided between the sprung member and the unsprung member, either oscillation-stimulating direction or oscillation-restraining direction with respect to vertical osciallation of the sprung member, and it also judges the size of the damping force of the shock absorber. The damping force characteristic of the shock absorber is set higher when it is larger than the predetermined value and it is set lower when it is less than the predertemined value. The predetermined value can be changed according to the road surface, oscillation-restraining energy becomes larger than the oscillation-stimulating energy thereby.

Abstract: A control system for a vehicle engine coupled with an automatic transmission, which comprises a torque controller operative to vary torque produced by the vehicle engine, in accordance with a controlled variable, so as to suppress torque shock resulting from a speed change operation carried out to vary a gear ratio in a power transmitting gear arrangement provided in the automatic transmission, an operation detector for detecting the speed change operation, a controlled variable setting device for determining the controlled variable in accordance with an operating condition of the vehicle engine and the speed change operation, and a controlled variable revising device for varying the controlled variable so as to reduce variation in the torque brought about by the torque controller under a condition in which the speed change operation causing a change from one to another of speed ranges of relatively small gear ratios is detected by the operation detector, as compared with variation in the torque brought about

Abstract: A windowpane for an automobile includes a inner and outer surface having a curvature corresponding to a portion of a surface of one of either a cylindrical body or a conical body. The windowpane is mounted in the automobile such that one of either a front edge or a rear edge thereof is positioned closer to a vertical plane extending vertically from a front center portion to a rear center portion of the automobile. Furthermore, a central axis of curvature defined by the curvature of the windowpane is slanted relative to a horizontal plane of the automobile. The windowpane is mounted in the side door of the automobile. The side door can be one of either a front side door or a rear side door and can be one of either a sash type door, an inner sash type door, or a sashless type door.

Abstract: A throttle opening controller provided between an accelerator pedal and an engine throttle of an automobile. It has an output shaft driven by a motor, a motor lever fixedly mounted on the output shaft and ring members including an accelerator ring, a motor ring and a throttle ring all rotatably mounted on the output shaft. The accelerator ring is connected to the accelerator pedal and the throttle ring is connected to the throttle through wires. The motor lever is controlled by a traction control device. When the traction control is not activated, the motor lever is kept in its FULL-OPEN position, allowing the movement of the accelerator pedal to be transmitted as it is to the throttle through the accelerator ring, the motor ring coupled to the accelerator ring through a spring, and the throttle ring adapted to turn in the throttle-opening direction by and with the motor ring.

Abstract: An arrangement for forming an automobile cowl structure comprises a windshield supporting frame with a closed cross section provided for supporting a lower end of a front windshield and composed of a cowl top member formed in the shape of a bank protruding upward and elongating along the front windshield in the direction of the width of an automobile body construction and a cowl cover panel provided with the cowl top member fixed thereon and having a prolongation thereof horizontally extending backward beyond a rear end portion of the cowl top member, and an upper dash panel having a rear end wall portion thereof connected to a rear end portion of the prolongation of the cowl cover panel at its upper end.
