Abstract: An assembly of parts has a first metal part having a first surface having a corrosion resistant surface treatment and a second surface being free of corrosion resistant surface treatment, a second metal part having a third surface having a corrosion resistant surface treatment and a fourth surface being free of corrosion resistant surface treatment. The second metal part defines a recess that defines the fourth surface. The first and third surfaces are in contact. A conductive member is disposed at least in part in the recess and is in contact with the second and fourth surfaces. A sealing member disposed in the recess around the conductive member. A sacrificial anode is mounted and conductively connected to one of the first and second metal parts.

Abstract: A control unit assembly is disclosed including a housing, at least one processor to control operation of an engine, and a voltage regulator configured to regulate a voltage of at least one rail of the engine. The at least one processing unit and the voltage regulator reside on a common circuit board.

Abstract: An apparatus and method are presented to dynamically control operation of an engine component, e.g. fuel pump assembly or oil pump assembly, so that the engine component is operable at voltages that exceeds its rated or maximum operational voltage. An engine control monitors the rail voltage provided by an engine's energy source and provides a dynamic control of the engine component to be operable at that rail voltage. In this regard, the engine component is controlled to be operable at voltages exceeding its rated or maximum operational voltage, but is also controlled to be operable at varying voltages that are above its rated maximum.

Abstract: A start-assist circuit for increasing the fuel-injection voltage during the startup of an internal combustion engine having fuel injectors, a starter solenoid, and a battery is provided. The boost circuit receives the battery DC power and then boosts the battery voltage to provide an output having a level sufficient for a fuel injection solenoid during the start process.
