Description
(1) technical field
The present invention relates to a kind of gas engine, particularly a kind of fuel gas injection valve and high-pressure injection pump gas driving fuel injection system.
(2) background technique
As everyone knows, gas engine be by inflammable mixture in cylinder by breaking out work done after the spark ignitor, promote piston up-down, thereby and then drive bent axle and rotate heat energy is changed into mechanical energy, and there is dual mode at present in the formation of inflammable mixture:
1. external mixture type: promptly before suction tude, combustible gas is mixed (volume ratio 15:1 ∽ 20:1) in proportion with air as Z12V190T type 12 cylinder natural gas engines and enter suction tude afterwards by special-purpose mixer, open by every cylinder intake valve then, after the descent of piston, inflammable mixture enters in the cylinder, again by the piston stroking upward compressing inflammable mixture gas, by promoting the descent of piston work done after the spark ignitor, this hybrid mode is called external mixture type.There is following problem in it:
1. air consumption height; Because of all being flammable mixed gas in the suction tude, each cylinder is (the inlet and outlet door is opened simultaneously, and live gas is directly lowered the temperature by inlet and outlet by suction tude) when scavenging, and inflammable mixture directly enters into outlet pipe, because of this part gas does not participate in work done, so directly cause waste;
2. excessive discharge temperature, the inflammable mixture that participates in scavenging in entering into outlet pipe after, the high-temp waste gas of being discharged in the cylinder is lighted and then is caused excessive discharge temperature (the usually outer gas engine row temperature of mixing is all more than 630 ℃), because of excessive discharge temperature causes the exhaust valve work under bad environment, significantly reduce the operating life of exhaust valve, increased the fault of gas engine simultaneously.
3. easily cause suction tude to blow out, because of being full of inflammable mixture in the suction tude, after the intake valve wearing and tearing are leaked gas in cylinder, the flame of lighting in the cylinder after the outburst is lighted inflammable mixture in the whole suction tude by the intake valve of gas leakage, cause suction tude to blow out, its consequence is the light relevant components and parts that then damage, and is as mixer etc., heavy then cause human casualty accident.
2. internal-mixing: the inflammable mixture of internal-mixing is before inlet casing, its combustion gas and air separate, intake valve is opened, combustible gas and air enter into respectively in the cylinder and mix after the descent of piston, afterwards behind the piston stroking upward compressing inflammable mixture gas by spark ignitor, promote to drive the bent axle rotation via connecting rod after the descent of piston, heat energy is become mechanical energy, this kind mode promptly is called internal-mixing.The internal-mixing of gas engine is compared with external mixture type and is had the following advantages:
1.. reduce air consumption: be the scavenging task finished by fresh air during because of cylinder scavenging, directly enter into outlet pipe so solved the part inflammable mixture, the problem that can not participate in work done and directly be burnt, interior usually mixed machine is saved more than 10% at least than mixing the machine gas consumption outward.
2.. delivery temperature is low: because of having avoided the burning of part inflammable mixture in outlet pipe, so significantly reduced delivery temperature, usually it is lower more than 80 ℃ than the outer machine delivery temperature of mixing to mix machine in, and then improved the working environment of exhaust valve, improve the working life of exhaust valve, and then improved the reliability of gas engine.With Z12V190T type gas engine is example, and the life-span of exhaust valve prolongs 1 times than the outer machine that mixes usually.
3.. eliminated the potential faults of after-burning: because of not had inflammable mixture in the interior mixed machine suction tude, even the intake valve wearing and tearing cause gas leakage, flame can not lighted the air in the suction tude yet in the cylinder, thereby has avoided suction tude to blow out the serious accident that is caused.
3. present interior mixed motor in the world has dual mode:
1.. the 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 morning and evening time of semaphore, to a certain amount of inflammable gas of cylinder inner direct, air then directly enters in the cylinder by another passage, 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; There is such gas engine in U.S. Caterpillar, and the used electrospray motor of its principle and present automobile is similar, and there are the following problems in the middle of reality is used but mix form in this:
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 the rock gas problem of dried and clean is little, but use coke-stove gas, oil well associated gas, draw rubbish to generate impurity such as gas, gas, tar, edible vegetable oil, the water yields when big, electromagnetic injection valve is with regard to cisco unity malfunction;
C. the problem of fuel gas injection amount is because of being subjected to 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, also limited simultaneously gas, coke-stove gas, ore cracking gas as low density, draw that rubbish generates that gas adopts this kind mode may.
2.. camshaft and stingy door mode are installed in the intake duct: with combustible gas via the control of suction tude inner camshaft by gas pipeline, little porthole, jet pipe with fuel gas injection near the intake valve of each cylinder, be ejected in the cylinder via intake valve, air is also brought cylinder into simultaneously with combustion gas near intake valve, light outburst after the piston stroking upward compression, promote descent of piston, and then the drive bent axle rotates, change heat energy into mechanical energy, U.S. cooper company and Nantong precious coltfoal company adopts this kind mode of structure, and there is following problem in this mode:
A. outside the main gas distribution timing system of the existing cover of 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 engine failure rate, brought the increase of noise simultaneously;
B. increased the cost of motor; With 500KW/Z12V190T type gas engine is example, and interior mixed machine on average exceeds more than 200,000 yuan 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.
It is main mixing beyond the present domestic inlet gas motor, simultaneously with a spot of electromagnetic injection type, and domestic gas engine is equally also based on external mixing type, as Jinan Diesel Plant, triumph power generating machine factory etc., and private corporations such as the precious coltfoal in Nantong, Jiangsu Sheng Yuan are mainly based on intake duct inner camshaft, little air gate distribution ejecting system, this kind structure is higher because of cost, and the occupancy in market is relatively low at home at present.
