Abstract
The present invention relates to gas burning engine, and is especially one anti-knock set, which utilizes the combustion retarding effect of waste gas of gas burning engine in lowering the combustion speed inside the cylinder. Technologically, the anti-knock set includes waste gas treating device, regulating valve and electronic control system. The waste gas treating device includes cooler and water eliminating treater, and the treated waste gas is then pressure stabilized in the pressure stabilizer and fed to the mixer through the regulating valve controlled with the electronic control system. The waste gas pipe is provided with fire back preventing safety unit. The present invention has the beneficial effect of introducing partial waste gas into the cylinder to inhibit knock and avoid the drastic change in the running state of the gas burning engine.
Description
One, technical field
The present invention relates to the gas engine field, use the pinking that produces when this system can suppress gas engine work effectively, make gas engine work soft, reduce combustion noise and exhaust pollution simultaneously.
Two, background technique
Gas engine has the advantages that to be different from diesel engine and petrol engine, the fuel pressure and the composition of its use have polytrope, production firm is when making great efforts to improve power per liter, near point of detonation, particularly the easier gas engine that causes of propellant composition or variation in pressure produces pinking when high capacity when having caused gas engine work inevitably.Therefore, in order to address this is that, invented gas engine antiknock shake device.
Three, summary of the invention
The present invention is the fire retardation that utilizes gas engine waste gas, reduces cylinder fuel combustion speed, and a kind of gas engine antiknock shake device of design.
The principle that adopts is: electronic engine management system is according to combustion position, with the part waste gas of its eliminating after treatment, quantitatively imports suction tude, with fuel, air mixing, participates in combustion process in cylinder.The main component of waste gas is CO
2, in fuel combustion process, complicated chemical change takes place, the performance fire retardation.Its mechanism of action can be used reaction equation explanation down:
During the burning beginning, CO in the waste gas
2Combine with C in the part of fuel and to generate CO, cause the fuel can not be directly and O
2React, reduce velocity of combustion (chemical reaction velocity decline just).When burning proceeds to certain phase, CO and O
2React, discharge calory burning.In addition, in cylinder, away from the not combustion district of combustion flame, because O
2The content relative deficiency, the condition that pinking produces is destroyed, and therefore, pinking just can not be easy to take place.
Technological scheme of the present invention is: mainly comprise: emission-control equipment, modulating valve, electronic control system are formed, wherein emission-control equipment comprises cooling, removes water processor two-part composition, enter voltage stabilizing in the pressure stabilizer then, quantity of inhale gas by electronic engine management system regulating and controlling valve after, enter mixer.Waste gas is quoted pipe anti-backfire safety installations is housed.
The invention has the beneficial effects as follows that after part waste gas was introduced into cylinder, because the generation of pinking is effectively suppressed, so gaseous-pressure or composition be when changing, rapid change can not take place in the operation conditions of gas engine.
Four, description of drawings
Accompanying drawing is a gas engine antiknock shake device schematic representation.
Among the figure: 1. electronic control system, 2. mixer, 3. modulating valve, 4. pressure stabilizer, 5. flame trap, 6. emission-control equipment, 7. gas engine.
Five, embodiment
In conjunction with the accompanying drawings, the directly emptying of a waste gas part that gas engine 7 is discharged, another part enters emission-control equipment 6.The main effect of emission-control equipment 6 is coolings, dewaters.Waste gas after treatment enters in the pressure stabilizer 4 by flame trap 5, forms pressure stable, arrive modulating valve 3 then before.Simultaneously, electronic control system 1 is according to the gas engine 7 working condition signals that collect, judge whether pinking and pinking degree, and calculate the exhausted air quantity of need introducing, again result of calculation is converted into coherent signal, the regulating and controlling valve opening is accurately adjusted and is entered the exhausted air quantity of suction tude, at this moment, the direct emptying of unnecessary waste gas.
Waste gas through quoting enters cylinder together in company with air, combustion gas at last.During fuel combustion,, effectively suppressed the generation of pinking, reached antiknock purpose because the existence of waste gas has reduced its velocity of combustion.
Claims (2)
1, a kind of anti-knock system of gas engine, it is characterized in that mainly comprising: emission-control equipment, modulating valve, electronic control system are formed, wherein emission-control equipment comprises cooling, removes water processor two-part composition, enter voltage stabilizing in the pressure stabilizer then, quantity of inhale gas by electronic engine management system regulating and controlling valve after, enter mixer.
2, gas engine antiknock shake device according to claim 1, it is characterized in that: waste gas is quoted pipe anti-backfire safety installations is housed.
