摘要： An EGR valve position control system includes an EGR valve manager responsive to an EGR valve command to drive an EGR valve actuator. The EGR valve manager is operable to schedule control gains as a function of valve actuation direction to provide for faster response during valve closing events. Valve closing events are also staged such that a large valve position step is followed by a steady ramp to the valve closed position to thereby prevent damage to the valve and/or valve seat. The EGR valve manager further includes a prioritized switching feature for strategically switching between closed and open loop control modes, and a forward gain adjustment feature responsive to battery voltage to maintain constant system DC gain under changing battery voltage conditions.

摘要： An improved system for automatically continuously replacing an engine's used lubricating oil with fresh lubricating oil throughout operation based on engine operating conditions is disclosed. The present system includes an intermittent injection control device for intermittently injecting small amounts of used lube oil into the engine's fuel system. An electronic controller is provided to vary the amount of used lube oil injected into the oil system based on the severity of engine operation. The system periodically determines an engine operating severity value, i.e. fuel consumption value, for an interval of engine operation and calculates a base line quantity of oil for injection based on the current fuel consumption of the engine during the current interval. The system may also include an auxiliary flow control device for directing controlled quantities of fresh oil into the engine's lube oil system for maintaining the engine's oil sump at a proper level. The system maintains the quality of the engine lube oil at a level necessary to provide optimal engine protection at all engine operating conditions while also maintaining the oil concentration in the engine's fuel at an acceptable level.

摘要： A dual throttle system for an internal combustion engine includes first foot pedal throttle and a second hand controller throttle. The system includes a throttle position signal generator that produces a throttle position signal at an input to an electronic engine control module (ECM). The engine control module uses the throttle position signal input to determine an engine speed and issues appropriate commands to a fuel system controller. The throttle position generator includes a first potentiometer having its wiper mechanically connected to the first throttle and its output electrically connected to the throttle position signal input of the ECM. The first potentiometer is connected in series between a voltage source in the ECM and the wiper of a second variable resistance component driven by the second throttle. The output of the second component is connected to ground to complete the series circuit. The voltage seen at the throttle signal input of the ECM is a function of the combined series resistances of the potentiometer and the second variable resistance component based upon the positions of the respective throttles.

摘要： An improved method and system for automatically continuously replacing an engine's used lubricating oil with fresh lubricating oil throughout operation based on engine operating conditions is disclosed. The present system includes an lube oil replacement pump system operable in a replacement mode for injecting small amounts of used lube oil into the engine's fuel system and directing controlled quantities of fresh oil into the engine's lube oil system to replace the removed oil. The process periodically determines an engine operating severity value, i.e. fuel consumption value, for an interval of engine operation and calculates a base line quantity of oil for injection based on the current fuel consumption of the engine during the current interval. The lube oil replacement pump may also be operated in a makeup mode for adding quantities of fresh oil to the engine lube oil sump to compensate for oil consumed by the engine. The system adjusts the quantity of used oil to be removed and injected based on the quantity of fresh oil supplied during the makeup mode to prevent overreplacement of the lube oil. The lube oil pump system may be in the form of a compact, unitized lube oil replacement pump assembly integrating the various components of the system. The system maintains the quality of the engine lube oil at a level necessary to provide optimal engine protection at all engine operating conditions while also maintaining the oil concentration in the engine's fuel at an acceptable level.
