摘要： The object of the invention is to provide an improved graphic display meter which is prevented from causing inconvenience to the vehicle operator, when a motion blur display mode is switched to a normal display mode.When a motion blur pointer image 10 is switched to a normal pointer image 20a, multiple pointer images 20 including the normal pointer image 20a are displayed adjacent to or in abutment with a leading part of the motion blur pointer image 10 in a direction where the pointer is rotating. The multiple pointer images 20 are consisted of the normal pointer image 20a and a plurality of auxiliary pointer images 20b, which are aligned with one another and are positioned in close proximity to the normal pointer image 20a. The multiple pointer images 20, a plurality set of which have been stored as data in advance, are selected on the basis of a space between the motion blur pointer image 10 prior to the switching of the pointer image and the normal pointer image 20 after the switching of the pointer image.

摘要： An engine air-fuel ratio control system is configured to use a rich air-fuel ratio immediately after starting an engine such that the air-fuel ratio converge rapidly toward a stoichiometric value and then afterwards start an air-fuel ratio feedback control. Upon determining an air-fuel ratio sensor is active, a stabilization fuel quantity increasing factor that is a component of a target air-fuel ratio revising coefficient is decreased at a higher rate than the rate used before the air-fuel ratio sensor was determined to be active. Air-fuel ratio feedback control is started when the air-fuel ratio corresponds to a stoichiometric air-fuel ratio. After starting air-fuel ratio feedback control, an unburned fuel quantity compensating value is set based on the stabilization fuel quantity increasing factor in effect at that point in time and added to the target air-fuel ratio revising coefficient while, simultaneously, the stabilization fuel quantity increasing factor is set to zero.

摘要： A spark ignition engine (2) has a fuel injector (8) in an intake port (7). An engine rotation speed sensor (9) detects the rotation speed of the engine (2). The controller (1) determines the target fuel injection amount of the fuel injector (8) during startup of the engine (2) by correcting the basic injection amount in response to the trend in the variation in the engine rotation speed. When the rotation speed of the engine (2) decreases, the controller (1) sets the target fuel injection amount to be smaller than when the rotation speed of the engine (2) is increasing at an identical rotation speed. As a result, effects on the air-fuel ratio related to wall flow relative to fluctuations in the rotation speed of the engine (2) are eliminated and the control accuracy of the air-fuel ratio of the engine (2) is improved.
