Description
Technical field
This patent relates to a kind of gas engine annex, particularly a kind of drum type combustion gas injection valve.
Background technique
International at present, domestic more advanced gas engine all adopts gas-duct jetting formula (being called for short MPI abroad): the inflammable mixture of this mode is before inlet casing; Its combustion gas and air are near intake valve, to mix; Intake valve is opened; Inflammable gas and air enter into and light the back acting in the cylinder simultaneously through intake valve behind the descent of piston.This mode also is called as half internal-mixing simultaneously.With traditional external mixture type (air fully mixes in suction tude with combustion gas), advantage such as gas engine is compared, and it is low that it has amount of consumed gas, and delivery temperature is low, eliminates the hidden danger that suction tude is blown out basically, and the motor dynamic characteristic is good.
1, present gas-duct jetting formula motor in the world has two kinds:
1. electromagnetic injection formula: it is to send electrical signal by analog circut or Digital Circuit Control plate; After accepting electrical signal by electromagnetic injection valve, according to what and time of semaphore sooner or later, near a certain amount of inflammable gas of the direct injection intake duct intake valve; Combustion gas and air all directly enter in the cylinder through intake valve; Form inflammable mixture, after the piston stroking upward compression, by promoting descent of piston after the spark ignitor and then drive the bent axle rotation that heat energy is transformed into mechanical energy; U.S. Caterpillar Tractor adopts the gas engine of this type of pattern, and the used electrospray motor of its principle and automobile at present is similar, but there is following problem in this gas-duct jetting formula in the middle of reality is used:
A. electrical signal control poor anti jamming capability is stable not as external mixture type;
B. solenoid valve is had relatively high expectations to the inflammable gas cleanliness; If what use is that dry, clean rock gas problem is little; But when using impurity, tar, edible vegetable oil, the water yields such as coke-stove gas, oil well associated gas, rubbish generation gas, gas big, electromagnetic injection valve is with regard to cisco unity malfunction;
C. the problem of fuel gas injection amount is because of receiving the restriction of electromagnetic signal and electromagnetic injection valve power controlling; It is excessive that electromagnetic injection valve can not be done; Be that the fuel gas injection amount is limited; So just limited the possibility that large-scale gas engine adopts this kind mode, the gas, coke-stove gas, ore cracking gas, the rubbish that have also limited the picture low density simultaneously generate the possibility that gas adopts this kind mode.
2. mounting cam axle and stingy door spray regime in the intake duct: with combustible gas via the control of suction tude inner camshaft through gas pipeline, little valve, jet pipe with fuel gas injection near the intake valve of each cylinder; Enter in the cylinder via intake valve, near intake valve, air is also brought cylinder into combustion gas simultaneously; Light outburst after the piston stroking upward compression; Promote descent of piston, and then drive the bent axle rotation, change heat energy into mechanical energy; U.S. cooper company adopts this kind mode of structure, and there is following problem in this mode:
A. had outside the main gas distribution system of a cover in former gas engine; Increased by a cover fuel gas injection gas distribution timing system again; Great number of driving parts, camshaft parts, rocker part, stingy door part and valve seat parts have been increased; So just increase the breakdown in the motor rate, brought the increase of noise simultaneously;
B. increased the cost of motor; With Z12V190T type gas engine is example, and interior mixed machine on average exceeds more than 200,000 than outer every the price of machine of mixing.
C. because of gas distribution system complex structure in the suction tude, this kind structure applications compares difficulty on large-scale gas engine, and the lead time is longer, and component are made difficulty.This kind gas distribution system receives structural limitations simultaneously; The fuel gas injection amount is limited equally, and combustion gas in the above scope of calorific value in only being fit to is if use low-BTU gas; Especially during the higher combustion gas of low, carbon monoxide of methane content and hydrogen; Its rated output power just has decline by a relatively large margin, and exert oneself during extreme case and have only below 30% of middle calorific value gas rated output power, be example with calorific value gas engine among the 500KW; Many low-BTU gas maximum outputs have only about 150KW, have so just caused the lower stock utilization and the bigger wasting of resources.
