Title: Fuel supply control method for internal-combustion engine
Inventor: YAMATO AKIHIRO
IPC: F02D41/12
Filed: 1983-06-10
Abstract: PURPOSE:To decrease the amount of unburnt fuel to be fed in a catalyst, and prevent burnout of the catalyst, by stopping fuel supply to a main injector at fuel cutting or reduced-cylinder operation, and simultaneously stopping fuel sup- ply to a corresponding sub injector provided in an auxiliary combustion chamber. CONSTITUTION:An electronically control unit 9 serves to judge whether or not a present engine operational condition is at fuel cutting or reduced-cylinder operation by using a vehicular speed, rotational speed signal and vacuum signal. If the engine operational condition is at fuel cutting or reduced-cylinder operation, the amount of fuel to be injected to a main injector is rendered zero, and simultaneously the amount of fuel to be injected to a sub injector is also rendered zero. Thusly, the amount of unburnt fuel to be fed in a catalyst may be decreased.

IPC: G06F11/30
Filed: 1990-04-19
Abstract: PURPOSE:To monitor the runaway of a CPU without using any software exclusive for a watchdog timer WDT by defining an OR of plural addresses which are certainly used by the software within a fixed time as the input of the WDT. CONSTITUTION:One of both address A2 and AM of the ADC 21 and 2M is used within a fixed time and then outputted through one of both output terminals 21o and 2Mo of the ADC 21 and 2M respectively. The outputs of the terminals 2o and Mo are used as the inputs applied to the input terminals 32 and 3M of an OR circuit 3. Then an output terminal 3o has an output with the output of the address A2 or AM since an OR is secured. The output received from the terminal 3o is inputted to an input terminal 41 of a WDT 4. Thus a counter of the WDT 4 is reset when the address A2 or AM is used. As a result, the runaway of a CPU 1 is monitored without using any software exclusive for the WDT 4.
