20130133197 | METHOD OF MODIFYING ENGINE OIL COOLING SYSTEM - A method of modifying the oil cooling system of a diesel engine an engine oil supply outlet located in a horizontal plan includes the steps of removing the original equipment liquid-to-liquid heat exchanger and installing a manifold having an oil outlet port directed to a remote oil cooler and a bypass water passage providing an un-branched flow of water, whereby the flow of oil is directed to a remote oil cooler and the entirety of the flow of water in the bypass water passage is discharged back to the water cooling system of the engine without passing through an oil cooling or water cooling heat exchanger. | 05-30-2013 |
20130255081 | METHOD OF MODIFYING ENGINE OIL COOLING SYSTEM - A method of modifying the oil cooling system of a diesel engine an engine oil supply outlet located in a horizontal plan includes the steps of removing the original equipment liquid-to-liquid heat exchanger and installing a manifold having an oil outlet port directed to a remote oil cooler and a bypass water passage providing an un-branched flow of water, whereby the flow of oil is directed to a remote oil cooler and the entirety of the flow of water in the bypass water passage is discharged back to the water cooling system of the engine without passing through an oil cooling or water cooling heat exchanger. | 10-03-2013 |
20140317923 | OIL SYSTEM FOR DIESEL ENGINES THAT OPERATE IN COLD ENVIRONMENTS - An aftermarket modification for diesel engines that operate in cold environments particularly those using a liquid-to-air oil cooler. Engine oil can be routed to a bypass module having a thermostatic element that directs the oil to bypass the oil cooler and return to the engine if the engine oil is below the desired temperature. Once the desired oil temperature is reached, the thermostatic element moves toward a closed position to direct oil through the oil cooler. A pressure bypass element can be incorporated into the bypass module. If the pressure differential between the inlet and outlet of the cooler exceeds a set point, the bypass element moves toward an open position to direct a portion of the oil to bypass the oil cooler. | 10-30-2014 |
20140352147 | METHOD OF MODIFYING ENGINE OIL COOLING SYSTEM - A method of modifying the oil cooling system of a diesel engine includes the steps of removing the original equipment liquid-to-liquid heat exchanger and installing a manifold having a configuration adapted to match the mounting configuration of the oil passages of the original equipment liquid-to-liquid heat exchanger. The manifold has an oil outlet port directed to a remotely mounted oil cooler. The manifold also has a water passage having a configuration that is adapted to match the mounting configuration of the water passages of the original equipment liquid-to-liquid heat exchanger. The water passage causes the entirety of the flow of water to be discharged back to the water cooling system of the engine where it is circulated by the water pump through the water cooling passages in the engine. | 12-04-2014 |
20140352671 | METHOD OF REBUILDING AN EGR COOLER - A method of rebuilding a salvaged EGR coolers is disclosed in which the existing heat exchanger elements are removed from the salvaged stock EGR cooler housing and replaced with a heat exchanger element made from a pair of heat exchanger tube sub-assemblies. Each of the heat exchanger tube sub-assemblies includes an end plate with a selected number of attached tubes and a selected number of bores, which are adapted to receive the ends of the tubes attached to the other tube sub-assembly. The tube sub-assemblies are mated together with the free ends of the tubes received into the bores of the opposite end plate. Exhaust fittings are then welded to the ends of the housing. | 12-04-2014 |
20150101190 | METHOD AND APPARATUS FOR REPAIRING A CYLINDER HEAD - An apparatus and method are presented for repairing damage to the boundary wall between an engine coolant passage and a fuel injector bore in a cylinder head. The method involves removing the fuel injector from the fuel injector bore adjoining the damaged boundary wall and inserting a purpose-built sealant injector tool into the fuel injector bore. The sealant injector tool is dimensionally equivalent to the fuel injector in critical regions so that it conforms to the interior surface of the fuel injector bore. Sealant is injected into the sealant injector tool at high pressure until the sealant flows into the crack between the fuel injector bore and the coolant passage after which the sealant injector tool is removed and the fuel injector reinstalled. | 04-16-2015 |
20150144080 | APPARATUS FOR MODIFYING ENGINE OIL COOLING SYSTEM - A method of modifying the oil cooling system of a diesel engine includes the steps of removing the original equipment liquid-to-liquid heat exchanger and installing a manifold having a configuration adapted to match the mounting configuration of the oil passages of the original equipment liquid-to-liquid heat exchanger. The manifold has an oil outlet port directed to a remotely mounted oil cooler. The manifold also has a water passage having a configuration that is adapted to match the mounting configuration of the water passages of the original equipment liquid-to-liquid heat exchanger. The water passage causes the entirety of the flow of water to be discharged back to the water cooling system of the engine where it is circulated by the water pump through the water cooling passages in the engine. | 05-28-2015 |
20160082493 | METHOD AND APPRARATUS FOR FORMING A HELICAL TUBE BUNDLE - Apparatus and method for forming a plurality of elongate members into a helical bundle in which a pair of bending die assemblies are mounted on a moveable carriage, the moveable carriage itself being supported by a frame. The bending dies each have a plurality of grooved rollers that engage the sides of the tubes to apply a bending force while allowing the tubes to move longitudinally through the die assemblies. The die assemblies can be rotated independent of each other or in unison by means of stepper motors. A collet, attached to the frame, holds the ends of the tubes during the bending operation. | 03-24-2016 |
20160082556 | METHOD AND APPARATUS FOR FORMING A HELICAL TUBE BUNDLE - Apparatus and method for forming a plurality of elongate members into a helical bundle. The apparatus has a plurality of bending die heads that are mounted in a circular array within a rigid housing. The bending die heads each have a pair of grooved rollers that engage the sides of the tubes to apply a bending force while allowing the tubes to move longitudinally through the bending die stock. The bending die heads can be rotated about their longitudinal axes to impart a helical twist to the tubes as they pass through the bending die stock. The apparatus also has a collet stock assembly, which consists of a collet that has a plurality of apertures equal to the number of tubes in the bundle to be formed. The collet stock is mounted to a housing that is secured to a carriage. The carriage is driven by motor and lead screw to move linearly along a track toward and away from the bending die stock while the collet is rotated at a predetermined speed to form a helical bundle. | 03-24-2016 |
