Electrical connector and a control valve including the same
An electrical connector includes a blade terminal configured to establish an electrical circuit. The electrical connector also includes a receiving terminal coupled to the blade terminal. The receiving terminal includes a bridge portion, a first leg extending from the bridge portion, and a second leg extending from the bridge portion and separated from the first leg by a slot defined by the bridge portion, the first leg, and the second leg. Moreover, at least one of the first leg and the second leg include a geometric feature extending into the slot such that the slot is configured to prevent insertion of a second electrical connector into the slot.
Control device for internal combustion engine
A control device for an internal combustion engine includes an internal combustion engine and a valve opening-closing timing control device. The valve opening-closing timing control device has a phase adjustment mechanism for setting a relative rotation phase of a driving-side rotator and a driven-side rotator. The phase adjustment mechanism overlaps a timing of opening an intake valve with a timing of opening an exhaust valve, by setting, in a predetermined period, the relative rotation phase such that the exhaust valve closes after a top dead center position has been reached, and a bypass passage is provided that connects an exhaust passage of one cylinder that is in an exhaust process to the exhaust passage of another cylinder that is in an intake process at the same time as the exhaust process.
