Abstract: The apparatus includes a housing; a plurality of sensors mounted on the housing, each of the sensors including a sensing element and an electrical output connected to said sensing element. The apparatus also includes a plurality of inputs connected to the sensors, respectively, to transmit to the sensors. A circuit is mounted in the housing and in electrical connection with the electrical outputs to provide a common signal conditioner for the sensors.

Abstract: A cold start air control device for an internal combustion engine of the type having an air delivery system in which the delivery of air to a vacuum generating manifold is controlled by a throttle valve and a by-pass valve and parallel with the throttle valve includes a casing that defines a passageway in parallel with the throttle valve and the by-pass valve and which has a cross-sectional area greater than that of the by-pass valve so as to offer a less restricted air flow path than that offered by the by-pass valve. The passageway provides communication between the manifold and atmosphere and a valve is disposed within the passageway for opening and closing the passageway in response to the vacuum level generated by the manifold.
