    摘要： A cleanable backflushable re-usable dual full-flow and bypass filter includes a full-flow filter element providing filtered primary flow therethrough, a bypass filter element providing filtered secondary flow therethrough, a bypass tube conducting flow therethrough from said bypass filter element to said full-flow filter element, a venturi creating a low pressure zone aiding secondary flow through the bypass tube to assist in pulling the secondary flow through the more restrictive bypass filter element, wherein fluid, whether main fluid flow in the filtering direction or backflushing cleansing fluid flow in the opposite direction, flowing from the bypass tube changes direction at the venturi. During a backflushing cleaning cycle, a backflush deflector at the outlet end of the bypass tube in the venturi creates the directional change by changing axial flow of cleansing fluid through the bypass tube to radial flow at the outlet end of the bypass tube in the venturi and prevents straight-through rectilinear flow of cleansing fluid from the bypass tube to the filter outlet. Jets are provided, jumping the cleansing fluid across a radial gap between the bypass tube and the venturi throat to a region outside of the venturi and within the hollow interior of the full-flow filter element, to disperse and backflush the full-flow filter element.

    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： 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.

    摘要： This invention relates to a fuel filter for use with internal combustion engines. The fuel filter includes a fuel additive that can be released into fuel. The rate of release for the fuel can be controlled. In one form the fuel additive can be mixed with a matrix material and released at a substantially constant rate to maintain a uniform level of fuel additive in the fuel. Use of the present invention provides a fuel filter having an extended life span that is longer than fuel filters typically used with combustion engines.
