20080314370 | Vehicle fuel preheater - The vehicle fuel preheater works on the known fact that by preheating the fuel, the fuel is more effectively vaporized, resulting in more efficient combustion. This preheating is accomplished using heat that normally cycles through the heater core for interior heat. The preheater, i.e., heat exchanger, has a housing, through which heated engine coolant on its way from the cooling pump to the heater core is routed. A coiled copper gas line is routed through the housing, and is connected between a segment of the fuel line and the engine combustion chamber so that the preheater can deliver preheated fuel to the combustion chamber. The heat exchanger is installed in a vertical orientation to prevent air lock in the fuel and cooling systems. | 12-25-2008 |

Additionally, the heat transfer system may be designed such that it may be used to retrofit an existing internal combustion engine. | 02-18-2016 |
20160138534 | HEATER DEVICE OF DIESEL FUEL FILTER - A heater device of a diesel fuel filter may include a heater housing inserted into a diesel fuel filter, and a heater portion inserted into the heater housing. A plurality of flow-path regions may be formed in the heater portion such that heated fuel passes through the heater portion. Accordingly, heat is transmitted directly from a heater portion including a plurality of heat radiating plates and PTC devices, and thus fuel is rapidly heated and a fuel transfer velocity is increased so as to improve engine starting performance at low temperature, thereby improving marketability and convenience. | 05-19-2016 |

20140165973 | FLUID HEATING DEVICE AND VEHICLE FUEL SYSTEM USING THE SAME - A fluid heating device of a vehicle fuel system includes: a case having a fluid inlet for letting in fluid, a fluid outlet for letting out the fluid, and an inner space that communicates with the fluid inlet and the fluid outlet; upper and lower power-supply and heat-radiation plates that are arranged in the inner space to be vertically spaced apart from each other, and supply external power; and one or more PTC elements that are interposed between the upper and lower power-supply and heat-radiation plates to receive the external power, and spaced apart from each other to form one or more fluid flow holes. Accordingly, the combustion of the fuel and the cold start performance of the vehicle can be improved. | 06-19-2014 |
20150047616 | FUEL VAPORIZER - What is described is a fuel vaporizer comprising a housing which comprises an inlet opening with an internal thread, an inlet tube which is seated in the inlet opening. According to this disclosure, it is provided that the inlet tube comprises an undercut head and the inlet tube protrudes through a bushing the inside diameter of which is smaller than the outside diameter of the head, wherein the bushing comprises an external thread with which it is screwed into the inlet opening of the housing. What is additionally described is a kit for the production of a fuel vaporizer. | 02-19-2015 |
20150330354 | GLOW PLUG CONTROL METHOD OF DIESEL HYBRID ELECTRIC VEHICLE - A glow plug control method of a diesel hybrid vehicle includes: determining an operation time of a glow plug based on a coolant temperature while the vehicle runs in an electric vehicle mode with an electric motor; determining whether the inside of an engine cylinder needs to be preheated based on the coolant temperature; comparing a driver-required power with a standard start power for determining whether to start a diesel engine; determining a glow plug operation time and a standard glow operation power, when the driver-required power is under the standard start power; operating the glow plug in advance, when the standard glow operation power is less than the driver-required power; and starting the diesel engine, when the driver-required power is higher than the standard start power. | 11-19-2015 |
