    摘要: An apparatus for reducing noxious gases in the exhaust emissions of an automobile is disclosed. During engine cold start, a cold start injector having a heater downstream of the injector outlet vaporizes fuel so that a leaner air-fuel mixture can be used, thereby reducing engine emissions before the engine and catalytic converter warm up. The heater includes various configurations for swirling the fuel and exposing it to large surface areas for improving the vaporization of the fuel. A tapered bore surrounding the throttle allows for precise air flow control into the cold start device during engine warm-up.

    摘要: A diagnosing system for an engine diagnoses malfunctions that occur in a direct-injection engine in which fuel is injected into combustion chambers or a lean-burn engine. The present invention provides a diagnosing system for an engine capable of diagnosing malfunctions in an intake air flow intensifying component and a fuel supply component and of specifying a malfunctioning part without being affected by the difference between different engines, the difference in quality between parts and aging. The diagnosing system for an engine comprises: a selecting component for selecting either a first air-fuel mixture control component or a second air-fuel mixture control component according to operating condition of an engine; a combustion condition detecting component for detecting combustion condition of the engine; and decision component for deciding a malfunction on the basis of a first combustion condition detected by the combustion condition detecting component in a state where the first air-fuel mixture control component is selected by the selecting component, and a second combustion condition detected by the combustion condition detecting component in a state where the second air-fuel mixture control component is selected by the selecting component.
