Title: Air/fuel ratio control device for internal combustion engine
Inventor: MITSUYA NORITAKE
IPC: F02D41/02
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To perform proper relearning a base air/fuel ratio feedback coefficient, by accurately detecting fuel vapor concentration purged in intake air, in air/fuel ratio control of an internal combustion engine. SOLUTION: A fuel vapor existing amount estimation value PGRtnk in a fuel tank is estimated from the balance between an estimation vapor generation amount t-PGRb and a fuel vapor estimation purge amount t-PGRo (S1220 to S1240). Since the fuel vapor existing amount estimation value PGRtnk is thus directly calculated fuel vapor concentration purged in intake air can be accurately estimated. The purged fuel vapor concentration is proved small when this fuel vapor existing amount estimation value PGRtnk is found small, and relearning of a base air/fuel ratio feedback coefficient can be performed in a proper condition. Consequently, wrong learning, even when it is performed can be returned to a proper learning value.

Title: Distributor type fuel injection pump
Inventor: YADA TOSHIKI
IPC: F02M41/12
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To surely stop an engine at the time of a totally closed failure of a fuel spill valve. SOLUTION: In a face cam type distributor type fuel injection pump 1, a plunger 14 revolving and reciprocating by synchronizing with an operation of an engine is stored in a cylinder disposed in a pump head 9. In midway of a suction passage 28, a fuel cut valve 40 is disposed. Between the fuel cut valve 40 and the pump head 9, a rubber gasket 44 for sealing high pressure fuel is disposed. In the cylinder 11, suction ports 26 are formed at two portions of a location on the opposite side of the suction passage 28 by 180 deg. across the plunger 14 and a location revolved by 90 deg. from the suction passage 28. When an electromagnetic spill valve 30 gets out of order in its totally closed state, fuel spill pressure acts on the fuel cut valve 40 after fuel spill pressure is reduced due to hitting on an inner wall of the pump head 9.  Therefore, a state that the gasket 44 is damaged and the stop of the engine becomes impossible due to the damage can be avoided.
