Title: Ignition timing control device for engine
Inventor: AZUMA TADAHIRO
IPC: F02P5/15
Filed: 1992-09-25
Abstract: PURPOSE:To provide a device enabling the rapid increase of engine speed even with cold start performed at the time of extremely low ambient temperature so as to prevent an engine stalling. CONSTITUTION:An electronic control unit 5 for controlling ignition timing is provided with an idle switch 3 for detecting the idling state, and an ignition timing delay side limiting means 8. The ignition timing delay side limiting means 8 compares basic ignition timing with the preset limit ignition timing at the time of the idling state and sets the target ignition timing to the limit ignition timing when the basic ignition timing is the value with more delay than the limit ignition timing. When cold start is performed at the time of outside air temperature being extremely low, the target ignition timing is limited so as not to be more delayed than the limit ignition timing in the idling state immediately after the start. The engine speed therefore rises speedily, so that a stalling is unliable to be generated.

IPC: G06F13/368
Filed: 1994-10-21
Abstract: PURPOSE: To properly arbitrate the bus use right of respective bus masters. CONSTITUTION: At the time of receiving a bus request signal BUS-REQ from its own bus master 12, a bus arbitor/requester (A/R) 14 compares its own priority data BUS-ID with priority data ARB-(n-1) obtained from a preceding stage. When the priority of the former data is higher than that of the latter, the former is outputted as its own priority data ARB-n and vice versa. Then the A/R 14 compares its own priority data BUS-ID with priority data ARB-3 outputted, from the final stage #3, and when the priority of the former data is lower than that of the latter, updates the data BUS-ID.  When the priority of the former is higher, the A/R 14 outputs a response signal BUS-ACK for permitting the use of a bus 10 to its own bus master 12, resets the data BUS-ID to '0' and outputs a bus request signal BUS-REQ to a succeeding stage #(n+1) When a bus request signal BUS-REQ is not outputted from its own bus master 12, the A/R 14 outputs the priority data ARB-(n-1) inputted from the preceding stage in response to the bus request signal BUS-REQ inputted from the preceding stage.
