20100077971 | Engine having fuel injector with actuator cooling system and method - An internal combustion engine, such as a direct injection compression ignition diesel engine, includes an engine housing having a plurality of cylinders and a plurality of fuel injectors associated one with each of the cylinders. The fuel injectors each include a first fuel inlet and a second fuel inlet, and an actuator subassembly which is configured to actuate a control valve assembly positioned within the fuel injector. The engine further includes a fuel system having a fuel supply circuit, and a cooling system for the actuator subassembly having a cooling circuit with a segment in common with a segment of the fuel system. The cooling system is configured to pass cooling fuel across a heat exchange interface of the actuator subassembly to exchange heat therewith. The actuator subassembly may include a piezoelectric actuator and a preloading spring, which are each fluidly sealed within a casing of the actuator subassembly. | 04-01-2010 |
20100218735 | ARRANGEMENT FOR COOLING OF OIL IN A GEARBOX FOR A VEHICLE - An arrangement for cooling oil in a gearbox in a vehicle which is powered by a combustion engine, the arrangement including an oil cooler, an oil system configured to circulate oil between the gearbox and the oil cooler, and a coolant circuit configured and operable to lead coolant to the oil cooler. The coolant circuit includes a radiator element for cooling the coolant and a line to lead the cooled coolant from the radiator element to the oil cooler. The coolant circuit has a flow-regulator to regulate the coolant flow through the radiator element for imparting to the coolant a temperature which makes possible a desired cooling of the oil in the oil cooler. | 09-02-2010 |
20100319638 | COOLING DEVICE FOR ENGINE AND/OR TRANSMISSION OIL, IN PARTICULAR OF AN INTERNAL COMBUSTION ENGINE - A cooling device for engine oil and/or transmission fluid, in particular of an internal combustion engine, has a flow-through oil cooler in an oil trough. The oil cooler is formed by a plate heat exchanger with plate intermediate spaces which route coolant and oil. The plate intermediate spaces that conduct oil have an outer opening region which is arranged on the outer circumference of the plate heat exchanger as inflow region, via which hot oil to be cooled flows into the oil-conducting plate intermediate spaces. Furthermore, the oil-conducting plate intermediate spaces have an outer outflow region which is arranged on the outer circumference of the plate heat exchanger at a distance from the inflow region. The outflow region is connected indirectly or directly to an outer oil line connecting region, via which cooled oil flows out after heat exchange with the coolant. The plate heat exchanger is suspended in the oil trough at a defined spacing from the oil trough walls which surround it. | 12-23-2010 |
20110232592 | IGNITION PLUG COOLING DEVICE OF VEHICLE-USE ENGINE - An ignition plug cooling device of a vehicle engine for efficiently cooling the ignition plugs while increasing the freedom in the arrangement of the ignition plugs. A vehicle engine includes a first ignition plug and a second ignition plug for making respective electrodes thereof face a combustion chamber and are mounted on a cylinder head. An air flow passage through which a flow of air passes and a cooling oil chamber through which lubrication oil for the engine passes are formed in the cylinder head. The first ignition plug is arranged in the air flow passage to enable a cooling of the first ignition plug by the flow of air which passes through the air flow passage. The second ignition plug is arranged adjacent to the cooling oil chamber to enable a cooling of an area around the second ignition plug by oil which passes through the cooling oil chamber. | 09-29-2011 |
20130269635 | Heat Exchange Medium - The present invention relates to the replacement of water and glycol mixtures by a synthetically made diesel as cooling medium, for instance engine coolant in vehicles. The synthetic diesel is environmental-friendly, usable in a wide temperature range, functions as corrosion protection in radiator systems, and transports heat better than water does. | 10-17-2013 |
20140311431 | INTERNAL COMBUSTION ENGINE - An internal combustion engine is provided. Facing pistons eliminate a cylinder head, thereby reducing heat losses through a cylinder head. Facing pistons also halve the stroke that would be required for one piston to provide the same compression ratio, and the engine can thus be run at higher revolutions per minute and produce more power. An internal sleeve valve is provided for space and other considerations. A combustion chamber size-varying mechanism allows for adjustment of the minimum size of an internal volume to increase efficiency at partial-power operation. Variable intake valve operation is used to control engine power. | 10-23-2014 |
20140366817 | Extended Operation Engine Coolant Composition - The invention relates to an engine coolant composition, and a method of increasing the operational life of a coolant composition in an engine, wherein an isononanoic acid is incorporated into the generally glycol based coolant fluid in place of nitrous acid or its salt to reduce pitting corrosion on iron containing surfaces. | 12-18-2014 |
20150361862 | OIL-COOLED CYLINDER BLOCK WITH WATER-COOLED BRIDGE - Systems are provided to providing water to the bore bridges of a cylinder block that contains an oil cooling system. An oil-cooled cylinder block may be desirable to aid in rapidly increasing engine temperature during engine warm-up, but high local temperatures may exist in the bore bridges in between adjacent cylinders, thereby leading to adverse performance. To control the high local temperatures while maintaining rapid engine warm-up, systems are proposed to provide water coolant from the cylinder head into cross-drilled passages located in the bore bridges of the cylinder block while cooling the rest of the cylinder block with oil or a different coolant. | 12-17-2015 |
