Title: Malfunction detection method for electromagnetically driven intake and exhaust valve
Inventor: YANAGIUCHI AKIHIRO
IPC: F02D41/22
Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To improve the detection accuracy for a malfunction of an electromagnetically driven valve by judging a power source for supplying power to the electromagnetically driven valve continuing to supply power of a predetermined reference value or below over a predetermined period of time to be malfunctioning. SOLUTION: When an upper coil 24 is energized, magnetic flux refluxes the magnetic circuit to produce electromagnetic force directed to displace a plunger 16 upward while when a lower coil 25 is energized, electromagnetic force directed to displace the plunger 16 downward is generated. The vertical, reciprocating motion of the plunger 16 by alternately energizing the coils 24 and 25 alternately drives a valve element 10 in its opened or closed direction.  For detecting a malfunction of such an electromagnetically driven intake and exhaust valve, the supply power Ps, or momentary power, of a power source is calculated based on the output from a source current detection circuit and a source power detection circuit as well as a criterion value Pref is calculated according to the quantity of intake air per one revolution of the engine with reference to the maps, which are used for the decision of a malfunction in the valve motion when Ps<=Pref.

Abstract: PROBLEM TO BE SOLVED: To enable access at a speed closer to real operating speed from an emulation chip by enabling direct access from the outside through an access means to a RAM when a storage means stores specified data at a microcomputer. SOLUTION: When a flag is set in a RAM free mode register 44a, a switching means 44b switches one part of connection between an input/output port 44 and a data bus 46a to connection with a control bus 46b and switches one part of the input/output port 44 to the input port of respective CSRAM bar and read permit/write permit signals. Besides, the switching means 44b switches one part of connection of the input/output port 44 to the connection of a RAM 43 with an address bus 46c and switches one part of the input/output port 44 to the address signal input port of the RAM 43. Further, the switching means 44b switches one part of the input/output port 44 to the connection with the data bus 46a and connects it to a data input/output port. Thus, the RAM 43 can be directly accessed from the outside.
