摘要:
When a vehicle state is detected during an engine is stopped, a sampling cycle of a detection signal indicating the vehicle state and a clock frequency of a CPU are changed, according to a change speed of the detection signal or an elapsed time after the engine is stopped.

When it is detected that any one of a plurality of variable valve characteristic mechanisms disposed for every cylinder groups is failed, an effective opening degree (valve lift amount, valve operating angle or the like) in a valve characteristic in the failed state, is obtained. When the effective opening degree is judged to be a predetermined value or above, the valve characteristic of the normal variable valve characteristic mechanism is controlled to be coincident with the valve characteristic in the failed state. When the effective opening degree is judged to be less than the predetermined value, there is performed a control for limiting the control to coincide the valve characteristic of the normal variable valve characteristic mechanism with the valve characteristic in the failed state.

An electromagnetic valve unit comprises a yoke of magnetic metal. The yoke includes upper and lower walls that are integrally connected by side walls. A slit is provided by the upper wall of the yoke. The slit extends along a longitudinal axis of the yoke between axially opposed ends of the yoke. A plurality of electromagnetic valves are abreast installed in the yoke in such a manner that the yoke constitutes outside magnetic paths of solenoid coils of the valves. Each of the solenoid coils has terminal members projected outward from the yoke through the slit.

In a configuration where it is judged whether or not a misfire occurred, based on the comparison between diagnosis data indicating a variation of an engine rotation speed and a threshold based on engine operating conditions, the misfire judgment is canceled based on a result of the comparison between data indicating an average correlation between the diagnosis data and the threshold, and a threshold for cancellation judgment.
摘要:
An electromagnetically actuated valve including a housing having a fluid path and a valve retaining bore located in course of the fluid path, a tubular valve casing mounted to the valve retaining bore, a valve body electromagnetically operative to axially move within the tubular valve casing and allow and prevent a flow of fluid passing through the fluid path of the housing, and a filter disposed at an axial end of the tubular valve casing. The filter includes a fluid passage communicated with the fluid path of the housing.

A brushless DC motor control system is arranged to control a command current indicative of a current to be supplied to the brushless motor on the basis of an estimated phase angle and an actual phase angle to control a current supplied to the brushless motor on the basis of an estimated phase angle and an actual phase angle, and to execute at least one of an estimated phase angle returning processing for returning the estimated phase angle and a current lowering processing for lowering a command current, when the estimated phase angle advances relative to the actual phase angle.

A valve timing control system includes a first device for changing a mounting angle between driving and driven rotators through relative rotation thereof and including first and second rotating mechanisms coupled to each other in series, and a second device for locking the first device at a mounting-angle position which is suitable for engine start and is set between a most-lagged-angle position and a most-advanced-angle position. The second device includes a first lock mechanism for locking the first rotating mechanism at one of the most-lagged-angle position and the most-advanced-angle position and a second lock mechanism for locking the second rotating mechanism at another position. The first and second rotating mechanisms are locked by the first and second lock mechanisms at opposite positions to maintain the mounting angle at the mounting-angle position suitable for engine start.
摘要:
An oil filter is provided which comprises a housing main body, a cover attached to the housing main body on the lower side thereof, an inner tubular member axially movably disposed in a recessed portion of the housing main body, a seal member interposed between the inner tubular member and the cover so as to provide a seal therebetween, a biasing unit for urging the inner tubular member in the direction to protrude from the recessed portion, and a filter element disposed in an oil flowing space between the housing main body and the cover, wherein when the cover is in a sate of being attached to the housing main body, the inner tubular member is pushed down into the recessed portion of the cover against a bias of the biasing unit.
摘要:
A valve timing control device for an internal combustion engine, comprises a drive rotary member rotated by a crankshaft of the engine, a driven rotary member to rotate a camshaft of the engine upon rotation of the drive rotary member; a rotational phase control mechanism having an intermediate rotary member rotated relative to the drive and driven rotary members to cause relative rotation between the drive and driven rotary members and an braking mechanism having a hysteresis brake that generates a braking force to cause the intermediate rotary member to rotate relative to the drive and driven rotary members.
