To provide a heater control device for an air-fuel ratio sensor and a heater control method for an air-fuel ratio sensor capable of executing appropriate heating control at the time of restart from an idling stop. [0002] A heater control device for an air-...

An engine air-fuel ratio control system (12) is configured to use a rich air-fuel ratio immediately after starting an engine (1) such that the air-fuel ratio converge rapidly toward a stoichiometric value and then afterwards start an air-fuel ratio feedbac...

Fuel injection correction amounts QiscON, QiscOFF1 and QiscOFF2 are respectively calculated depending on the operation ranges (S206, S208, S210). However, take-off assist correction itself is performed based on the total amount of all the fuel injection co...

In order to reduce white smoke emissions immediately after start-up, the present invention is a method for executing engine warm-up control using electronic control units, wherein start-up idle control, which does not perform the prescribed fast idle contr...

The method involves setting the fuel pressure (FUP) in a pressure reservoir to a starting value at the beginning of a starting process; starting the engine (M) with a starter revolution rate (N_Starter); determining the time in which the engine revolution ...
