Abstract
A gas engine using LPG or natural gas as fuel supply has a secondary vaporizer in between the reducer and distributor. The secondary vaporizer is comprised by a sealed water pipe and a sealed gas pipe which are connected side by side. On the secondary vaporizer may install a heating system and temperature sensor. The engine of this kind of structure is characterized of balanced gas distribution in each cylinder and stable running.
Description
Technical field
The present invention relates to a kind of gas engine, specifically, is a kind of gas engine of using liquefied petroleum gas (LPG) and natural gas as fuel.
Background technique
Be the demand of national environmental protection and fuel structure adjustment, in road and the water transportation, gas engine is main mode as power.
The gas engine that China uses now, its fuel supply system is divided negative pressure system and positive pressure system, mainly is made up of fuel air bottle, decompressor, control unit, wire harness, fuel display device, distributor (ejecting system) and nozzle.In the ordinary course of things, can normally use.But under following two kinds of situations, with regard to cisco unity malfunction: 1, a plurality of decompressor parallel connections are used for powerful gas engine: when two or two above decompressors are used on the high power gas motor, respectively each cylinder that starts is carried out fuel supply as each mixer, each decompressor can both be consistent at aspects such as gas fuel pressure after carburretion, the vaporization and density, like this when engine operation, the power that each cylinder of motor is exported is just different, and combustion gas is started can not be normally and stable operation; 2, outboard on-hook: the outboard on-hook is a kind of a kind of traffic tool that are used for lake and coastal waters, because of its cooling system adopts the outer circulation mode, when using gases fuel, to gaseous fuel required utilize in the engine-cooling system warm water to carry out carburretion the time, produce bigger influence.During engine idling operation, cooling water in the motor, along with the idle running time increases, it is very fast to descend, and makes the vaporization degradation of gaseous fuel.Particularly in gas continuous injection system, executive component on the fuel distributor---stepper motor, be contained in the on-hook cover, when the motor large load operation (so time fuel be to be in gas-liquid two-phase to supply with), can't use air to take away the cold air of assembling on the stepper motor, cause easy frosting to be frozen, influence the proper functioning of fuel supply system.
Summary of the invention
The object of the present invention is to provide the uniform gas engine of a kind of each cylinder air inlet.
Technological scheme of the present invention is, a kind of gas engine, comprise fuel air bottle, decompressor, control unit, wire harness, fuel display device, distributor (ejecting system) and nozzle, it is characterized in that: between the decompressor and distributor of described gas engine, a secondary carburetor is set, and this secondary carburetor seals mutually by two and water, the feed channel of thermo-contact constitute.
On the described secondary carburetor electric heating system and temperature transducer can also be set.
Adopted the gas engine of this secondary carburetor structure, can further strengthen the vaporization of fuel, its pressure stabilization function can make each cylinder air inlet of motor even.After electric heating system and temperature transducer are set on the secondary carburetor, can when engine low-temperature starting-up, fuel be heated, improve the cold-starting condition.
Description of drawings
Fig. 1 is the secondary carburetor sketch of the embodiment of the invention.
Fig. 2 is the secondary carburetor sketch that electric heating tube and temperature transducer are housed.
Fig. 3 is the systematic schematic diagram that secondary carburetor is used for gas engine.
Embodiment
The present invention is further described below in conjunction with drawings and Examples.
Referring to accompanying drawing 1, the described secondary carburetor 1 of present embodiment, constitute by two water, feed channel of sealing also thermo-contact mutually, water-in and water-out interface 2 constitutes waterpipe with water cavity 3 and intake-outlet 4, air inlet/outlet 5 constitutes feed channel with air cavity 6 and air inlet/outlet 7, water and gas are taken their own roads in secondary carburetor 1, and can carry out heat exchange.
Referring to accompanying drawing 2, electric heating tube 8 and temperature transducer 9 devices are at a wall of secondary carburetor 1, and link to each other with the control unit of gas engine respectively, detecting gas in the air cavity 6 at temperature transducer 9 crosses when low, send signal to control unit, control unit starts electric heating tube 8, and the gas in the air cavity 6 is heated.
Referring to accompanying drawing 3, the secondary carburetor 1 of present embodiment, be connected between decompressor 10 and the distributor 11, suction tude and the intake pipe of importing secondary carburetor 1 respectively from the low-pressure gas and the hot water of decompressor 10 output, the output gas of secondary carburetor 1 is behind distributor 11, be dispensed to each cylinder of gas engine, the output water of secondary carburetor 1 connects cooler.The suction tude of decompressor 10 and intake pipe are connected to gas cylinder and gas engine respectively.Gas engine, decompressor 10, secondary carburetor 1, distributor 11 link to each other with control unit by guide line respectively.It is identical with existing gas engine that other of present embodiment do not stated part, here is not described further.
When a plurality of decompressors 10 are parallel to the high power gas motor, be connected on after each decompressor 10 by secondary carburetor 1, each decompressor 10 is together in parallel, after the output gas of each decompressor 10 enters secondary carburetor 1, further vaporization in secondary carburetor 1, and, carry out fuel supply to each cylinder of motor by distributor 11 with pressure stable.
Claims (2)
1, a kind of gas engine, comprise fuel air bottle, decompressor, control unit, wire harness, fuel display device, distributor and nozzle, it is characterized in that: between the decompressor and distributor of described gas engine, a secondary carburetor is set, and this secondary carburetor seals mutually by two and water, the feed channel of thermo-contact constitute.
2, gas engine as claimed in claim 1 is characterized in that: also be provided with electric heating system and temperature transducer on the described secondary carburetor.
