Abstract: Disclosed is a fuel vapor treating apparatus, in which fuel vapor evaporated in a fuel tank is not released directly into the atmosphere but is collected and treated. This apparatus is provided with a canister for collecting fuel vapor and a purge line for purging the fuel vapor collected in the canister to an intake passage of an engine. The canister has a first control valve for controlling introduction of fuel vapor thereto. The canister also has a second control valve for controlling the introduction of outside air and the exhaust of gas therefrom. The first control valve communicates with a vapor line extending from the fuel tank and is opened whenever the internal pressure of the fuel tank exceeds a predetermined level to introduce fuel vapor from the fuel tank into the canister. The second control valve is designed to communicate with the atmosphere and is opened whenever fuel is purged through the purge line to the intake passage to introduce outside air into the canister. The second control valve is opened whenever the internal pressure of the canister exceeds a predetermined level to exhaust fuel-free gas left after collection of the fuel. Both the first control valve and the second control valve are diaphragm check valves. The control valves are designed to be readily detached from the canister.

Abstract: A hydraulic control system for a continuously variable transmission having a cylinder for changing the effective diameter of a pulley to control a speed ratio of the transmission. The control system comprises a spool valve assembly communicating with the cylinder to control the supply and discharge flows of a fluid to and from the cylinder. The valve assembly comprises a shift-speed control valve unit for controlling a rate of variation in the speed ratio of the transmission. The shift-speed control valve unit has only two discharge ports associated with the fluid discharge from the cylinder. The shift-speed control valve unit may take the form of a spool valve having a spool axially movable to open and close the ports to permit and restrict the fluid flows through supply and discharge conduits communicating with the ports and the cylinder. The spool may only partially open the corresponding port to permit the fluid flow therethrough for supplying or discharging the fluid. The valve assembly may comprise a shift-direction switching valve unit for changing the direction in which the speed ratio is varied. The switching valve unit has only two discharge ports associated with the fluid discharge from the cylinder.

Abstract: An apparatus for controlling an continuously variable transmission (CVT) used for a power transmission system of a vehicle. The CVT is controlled such that an actual engine speed becomes a desired engine speed. The desired engine speed is set as a function of running parameter such as intake throttle position. When the CVT is controlled in the same way as at the steady state of the vehicle at the acceleration of the vehicle, the acceleration performance is degraded. Thus, according to the present invention, the speed ratio of the CVT is reduced when the acceleration of the vehicle is small, in spite of the requisition of the vehicle acceleration. As a result, satisfactory drivability is attained.

Abstract: In an automatic transmission, torque shocks are effectively reduced in specific downshifting conditions where relatively strong engine braking occurs as a result of downshifting. When a downshift command to the automatic transmission is detected when an accelerator pedal is not depressed, a valve opening command is issued to a throttle valve so that engine output will have increased by the time the downshifting action of the automatic transmission actually begins, ignition timing is delayed so that an increase in engine output resulting from the opening of the throttle valve by a throttle valve control means is offset for a period starting at the time the engine output actually increases as a result of the opening of the throttle valve by the throttle valve control means and ending at the time the downshifting action of the automatic transmission actually beings, and the ignition timing delaying is cancelled upon initiation of the downshifting action of the automatic transmission.

Abstract: An on-vehicle control apparatus having a throttle valve in an intake passage of the engine is disclosed. The system for actuating the throttle valve includes electric and mechanical components. A electrical motor incorporated in the electric component actuates the throttle valve. An electronic control unit (ECU) controls the motor such that the opening of the throttle valve matches a target opening, which corresponds to a manipulation amount of a gas pedal. When there is an abnormality in the motor, if the gas pedal is manipulated by a predetermined amount or more, the mechanical component couples the gas pedal with the throttle valve, thereby actuating the throttle valve. When there is an abnormality in the motor, the ECU cuts fuel supply to some of the injectors. This allows the actual torque of the engine to be slightly lower than a computed engine torque that corresponds to the amount of a gas pedal manipulation.

Abstract: An air-fuel ratio control system for an internal combustion engine which includes an evaporative fuel purge system having a canister for temporarily storing fuel vapor, detects an air to fuel ratio in the exhaust gas from the engine. An air-fuel ratio controller controls the air-fuel ratio in exhaust gas from the engine by varying a fuel quantity supplied to the engine so that the air-fuel ratio approaches a predetermined target air-fuel ratio. The evaporated fuel is purged from the canister at a specific purging rate determined based on engine operating conditions. An air-fuel ratio-shift is controlled based on the derivation of an amount by which the air-fuel ratio has shifted from the target air-fuel ratio due to a cause independent of the purging operation. The first amount, which is relatively constant over time in comparison to a second amount of air-fuel ratio shift occurring as a result of the purging operation, is derived based on a first detected air-fuel ratio-shift amount when the purge system is purging at a first purging rate. The second air-fuel ratio-shift amount is detected when the purge system is purging at a second purging rate different from the first purging rate.
