Abstract: A pressure-to-electric transducer having increased life potential is disclosed herein. The transducer is comprised of a canister having a movable wall member, electrical means for generating an electrical signal indicative of wall movement, and means to cause displacement of the movable wall member in response to a pressure variation on one side of said wall. The improvement is comprised of means for periodically adjusting the relationship of the electrical means so that wear caused by relative movement within the electrical means is uniformly distributed. In particular, the electrical means are comprised of a wound coil of resistive wire and a movable wiper means for sliding engagement with said coil. Means are provided to alter the relative angular position of the wiper means relative to the coil so that wear caused by the wiping action is uniformly distributed around the coil.

Abstract: A liquid injector manifold and mounting arrangement wherein the fuel injector is supported in the engine at one end in a cylindrical bore with the aid of a circular seal. The injector extends from the engine and is supported at its other end by an extending fitting which tees off from a tubular common rail liquid fuel manifold. The tubular liquid fuel manifold is supported by brackets at a raised elevation. The connection between manifold fitting and fuel injector also employs a cylindrical surface and circular seal connection.

Abstract: In a fuel control system of the type which combines signals indicative of engine speed and engine load to compute a fuel requirement signal, a passive, nonlinearizing circuit is interposed between the intake manifold pressure transducer and the main computing means. The nonlinearizing means is comprised of passive resistive elements in a series-parallel relationship to provide a suitably tailored output signal in response to a manifold pressure input signal.

Abstract: An exhaust gas recirculation flow control system for an internal combustion engine having valve means responsive to engine air flow and to recirculated exhaust gas flow and adapted to provide a scheduled flow control signal to an exhaust gas recirculation valve. Pressure responsive means are provided to sense engine air flow and recirculated exhaust gas flow so that these two variables may act singly or collectively through said valve means in order to provide exhaust gas recirculation to the engine''s intake manifold which begins smoothly and holds at a relatively constant or scheduled fraction of the engine air flow for maximum effectiveness and minimum loss in vehicle driveability. The exhaust gas recirculation control system inhibits exhaust gas recirculation until engine air flow has increased to some predetermined value and then passes exhaust gas to the intake manifold in a modifiable proportional relationship to the engine air flow. If the exhaust gas recirculation flow tends to become too high or too low a force unbalance created within the valve means closes or opens the exhaust gas recirculation valve an amount necessary to maintain a position such that the exhaust gas recirculation flow is controlled in an increasing relationship to the increasing engine air flow. As engine air flow continues to increase a point is reached in which a force unbalance is again created within the valve means causing the exhaust gas recirculation valve to completely inhibit recirculation of exhaust gas. A temperature responsive member may also be included being operative with the valve means in order to inhibit the flow of exhaust gas at a predetermined low ambient or engine compartment temperature.

Abstract: A pressure switch arrangement having a diaphragm exposed to a sensed pressure on both sides; one side communicating through a fluid delay restriction so that the delta pressure across the diaphragm is a function of rate of change of sensed pressure. A spring metal blade member bears against the rate diaphragm to provide a spring bias and also operates as an electrical contact support. A hard rubber abutment member forms the contact point between spring blade and diaphragm to dampen and suppress contact bounce.
