Abstract
The utility model discloses an improved fuel preheating device of an internal combustion engine, which comprises a fuel preheating chamber communicated with a cylinder exhaust pipe and a fuel heating tail pipe coming out of the fuel preheating chamber; the fuel heating tail pipe is connected with a high-pressure oil circulating pump; the fuel preheating chamber is connected with an exhaust chamber thereon; and a fuel preheating pipe connected with the high-pressure oil circulating pump is disposed in the exhaust chamber. The improved fuel preheating device can take fully advantage of smoke waste heat produced from the internal combustion engine to raise fuel temperature, ensure sufficient burning of fuel, and reduce pollutant emission.
Description
Technical field
The utility model relates to a kind of internal-combustion engine fuel-firing preheating device, particularly improved fuel of internal combustion engine Preheating unit.
Background technique
Usually, the temperature that improves the fuel oil of internal-combustion engine use in advance can reach the fuel consumption that reduces internal-combustion engine, the purpose of the power of content of harmful and raising internal-combustion engine in the tail gas of reduction engine exhaust, people have designed various fuel of internal combustion engine Preheating units for this reason, as the patent No. is 00268279.6, the Chinese utility model patent that name is called " the fuel-firing preheating device of internal-combustion engine " discloses the fuel-firing preheating device that a kind of high-temperature tail gas that utilizes engine exhaust among the tail gas manifold of internal-combustion engine comes the fuel oil that the preheating internal-combustion engine uses, and it can effectively utilize the fuel oil that high-temperature tail gas that engine exhaust comes out will send into before the internal-combustion engine and carry out preheating.Its deficiency is, the efficient of fuel-firing preheating is high not enough, and the high-temperature tail gas heat energy utilization of internal-combustion engine is insufficient.
The model utility content
The purpose of this utility model is to provide a kind of improved fuel of internal combustion engine Preheating unit, and is not only simple in structure, is easy to make install, and can fully improves the heat energy utilization rate of exhaust gases of internal combustion engines.
The purpose of this utility model is achieved in that a kind of improved fuel of internal combustion engine Preheating unit, comprise fuel-firing preheating chamber that is connected with cylinder exhaust pipe and the fuel Heating tail pipe that from the fuel-firing preheating chamber, passes, the fuel Heating tail pipe links to each other with the cycle of higher pressure oil pump, on the fuel-firing preheating chamber, connecting exhaust chamber, the fuel preheating pipe that links to each other with high-pressure circulation pump is being set in the exhaust chamber.
The utility model installs exhaust chamber additional on the fuel-firing preheating chamber, in exhaust chamber, install fuel preheating pipe additional, further improved the heat energy utilization rate of exhaust gases of internal combustion engines, can make full use of the fume afterheat raising fuel oil temperature that internal-combustion engine produces, guarantee that fuel oil can fully burn, reduce pollutant emission.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a linkage structure schematic representation of the present utility model.
Embodiment
