The need for maintenance regarding wire stretching and position displacement between a throttle valve and an operation member is eliminated. A wire throttle adjustment device 1 is for performing open-close adjustment of a throttle valve by pull operation of a wire 2. The wire throttle adjustment device 1 includes an operation member 10 connected to an end part 2A of the wire 2 and configured to perform the pull operation of the wire 2. The operation member 10 includes an action part 11 that is elastically deformable by the pull operation of the wire 2 in a fully-opened state of the throttle valve. The action part 11 includes an elastically-deformable elastic arm part 12 configured to swing together with the operation part 15 and extending from the pivotally-supported part 14, and the end part of the wire 14 is connected to a tip part of the elastic arm part 12.

An accelerator device includes: a support portion that is installable to a vehicle body; a shaft that is rotatably supported by the support portion; an operable portion that is rotatable integrally with the shaft and is depressible by a driver; an installation blocking portion that is formed in the support portion; and a full opening stopper that limits rotation of the operable portion in an accelerator opening direction when the full opening stopper contacts the operable portion. The installation blocking portion includes a space that opens toward the operable portion. A rib is formed in the space and joins between a top side inner wall and a bottom side inner wall of the space.

An hydraulic system for a working machine, the system comprising an engine, and an engine speed sensor configured to detect the engine speed; a travel pump configured to actuate a travel actuator, and a travel pump pressure sensor configured to detect the travel pump pressure; a service pump configured to actuate a service actuator, and a service pump pressure sensor configured to detect the service pump pressure; and a micro-controller unit configured to receive input values from each sensor, and configured to determine whether each input value is within a predetermined range where the engine will not stall. The micro-controller unit is configured to provide an output when at least one input value is outside the predetermined range.

A four cylinder engine including two outer cylinders valved to operate on a four cycle basis, the outer two cylinders being movable together in opposite directions than the direction of movement together of the two inner cylinders. The two inner cylinders valved to operate on a two-cycle basis. The four cylinders having fuel injectors for injecting an amount of fuel in an associated cylinder so as to cause a self-ignited power event to occur therein during each cycle. The engine, when embodied in a vehicle having a battery energized computer and manually operated accelerator pedal being selectively operated in three power levels: (1) a minimum fuel mode (2) an intermediate fuel mode and (3) a maximum fuel mode. (1) Enabling a two-third fuel saving (two injections out of a possible six) when in minimum fuel mode and (2) a one-third saving fuel (four injections out of a possible six) when in the intermediate mode. The two inner cylinders operate on the fuel sharing principles of the '769 patent when in the intermediate mode.

A failure diagnosis apparatus for an internal combustion engine is provided. The internal combustion engine is mounted on a vehicle. The failure diagnosis apparatus includes an electronic control unit. The electronic control unit is configured to: measure an abnormal time in which an abnormal state where an accelerator pedal operation amount is equal to or larger than a first specified operation amount and a rate of actual output torque to requested torque is smaller than a specified rate value continues; and record specified data for a failure diagnosis of the internal combustion engine on a recording device in the cases where the abnormal time is equal to or longer than a first specified time that is set in advance and the accelerator pedal operation amount is equal to or larger than a second specified operation amount that is larger than the first specified operation amount.

A vehicle includes an engine, a continuously variable transmission, an engine stop system, and a brake system. The brake system is configured to control a braking force of the wheel based on an operation state of a brake operating portion that is operated by a driver. The brake system includes a braking force adjusting device. The braking force adjusting device includes an actuator and an electronic control unit. The actuator is configured to adjust a braking force of the wheel. The electronic control unit is configured to, when the engine stop system stops the driving of the engine, control the actuator such that slip of a belt of the belt-type continuously variable transmission relative to the pulley becomes less than or equal to a predetermined allowable limit.
