Title: Engine controller
Inventor: YAMAMOTO SHIGERU
IPC: F02P5/15
Filed: 1991-12-19
Abstract: PURPOSE:To prevent a catalyst from being deteriorated by heat by making a large amount of fuel flow through a catalyst where a large amount of air is absorbed when a fuel cut-off condition changes into a fuel increasing condition. CONSTITUTION:An air-fuel ratio feedback control region and a high load increasing region are set by the load and speed of an engine, and to prevent the engine speed from exceeding a prescribed value, an excessive rotation fuel cut-off region is set. Immediately after the air-fuel feedback control region changes to a high load increasing region, fuel is increased, and after the excessive rotation fuel cut-off region changes to the high load increasing region, fuel increase is cut off for a prescribed duration. Moreover, after an overspeed fuel cut-off region changes to the fuel increasing region, an increase in high load is cut off. When the fuel cut-off region changes to the fuel increase region, ignition timing is compensated so as to carry out spark advance.
