A ring portion of a steering wheel is disposed to be inclined relative to a vertical direction with an inclined angle between 40 and 90 degrees, when viewed from a vehicle width direction, and a bag portion has a larger configuration than the ring portion so as to cover over the ring portion when an airbag inflation is completed. Accordingly, there can be provided the steering wheel equipped with the so-called donut type of airbag portion of a airbag device that can perform its advantages fully and thereby improve the driver's protection.

A control system in an automobile has a controller to provide an air-to-fuel ratio leaner than an ideally combustible air-to-fuel ratio when a lean control range of engine operating conditions is detected, and a controller to increase an air flow rate so as to enrich a fuel mixture when an engine operating condition is transitional to the lean control range. The control system conducts sequentially the lean control and the enrich control according to transitional patterns to the lean control range.

Engine control system

A fuel injection system for an internal combustion engine having the normal crankshaft and plurality of cylinders each with an intake passage and an exhaust passage. An intake stroke detector is provided for detecting if a particular cylinder of the engine is experiencing an intake stroke. Responsive to an intake stroke being detected, a fuel injector is actuated to inject fuel into the intake passage of the particular cylinder during its intake stroke. The engine is equipped with an exhaust gas recirculation system for recirculating a part of exhaust gases from the exhaust passage to the intake passage of each cylinder. A fuel injection timing control mechanism is provided for advancing the fuel injection timing responsive to operation of the exhaust gas recirculation system to control the fuel injection period relative to the intake stroke.
