Title: System and method for controlling direct injection variable valve timing engine
Inventor: RUSSEL JOHN DAVID
IPC: F02B75/12
Filed: 2000-10-13
Abstract: PROBLEM TO BE SOLVED: To enable shifting of an air-fuel ratio mode between air-fuel ratio areas which are not overlapped with each other while preventing abrupt fluctuation of engine torque in a direct injection engine. SOLUTION: When a combustion mode is shifted from a stratified charge combustion state to a uniform combustion state, for instance, a fresh air charging amount in a cylinder is speedily adjusted by adjusting intake manifold outflow control devices 52a, 52b, 130, 134, 136, 142, 144 such as cam timing, independently on manifold dynamic characteristics. Synchronous control between an inflow control device, such as a throttle valve 62, and the outflow control devices 52a, 52b, 130, 134, 136, 142, 144 is utilized for attaining speedy fresh air charging in the cylinder. It is thus possible to prevent discontinuity of engine torque during shifting the mode even when a cylinder air-fuel ratio is changed from a certain cylinder event to the next cylinder event.

Filed: 2000-10-20
Abstract: PROBLEM TO BE SOLVED: To provide a mobile phone that uses a key backlight or a backlight of a liquid crystal display device in common for a ringer notice so as to inform a user about the arrival of an incoming without the need for provision of a ringer LED. SOLUTION: The mobile phone is provided with a key backlight 2, a control circuit 7, an optical sensor 8 and a display device 5 or the like, and when the optical sensor 8 detects that the surrounding place (place in use) is dark, the key backlight 2 is continuously turned off in spite of presence of key entry. When a call arrives, the key backlight 2 blinks to inform the user about the arrival of incoming call. Since the key backlight 2 lights up continuously in the presence of key entry, the user can easily recognize the difference between the blinking and the continuous lighting and no inconvenience takes place even when the key backlight 2 is used in common for ringer indication.
