Description
Technical field
The utility model relates to a kind of internal-combustion engine, the internal-combustion engine of a plurality of plug ignitions of a particularly a kind of cylinder.
Background technique
The known working principle of internal-combustion engine is that air inlet, compression, acting, four strokes of exhaust (process) are a work cycle.The work cycle of going round and beginning again makes the internal-combustion engine continuous firing.Expansion stroke is a stroke in four strokes of internal-combustion engine, also is unique stroke that internal-combustion engine obtains power (power), and other stroke is the necessary link in work cycle of internal-combustion engine.Expansion stroke is unique stroke that internal-combustion engine obtains power, is internal-combustion engine active combustion process.Acting active combustion process is that piston at the end begins in budc degree, compression stroke; Piston stops during exhaust valve opening at certain degree after bottom dead center; Piston is in the burning of this stroke period, and active combustion exactly does work.The explosion pressure that this period burning is produced promotes the piston operation, and piston promotes crankshaft rotating by connecting rod, acting burning again and again, and bent axle constantly rotates, and internal-combustion engine obtains continuous rating.Exhaust stroke starts from exhaust valve opening, terminates in exhaust valve closure.Exhaust is in order to discharge the waste material after acting is burnt, for next work cycle is prepared.In the exhaust process, the intact sky combustion material of unburned burns away in cylinder, and the burning of piston in the time of this stroke is invalid burning.The internal combustion process of Here it is internal-combustion engine." breaking of ternary device ", effect are that being trapped in burns away to break in the breaking device melts, and makes the discarded mixed gas of last discharge, reaches the requirement of environment protectment protection the outer discarded mixed gas of discharge machine.The discarded mixed gas that the discharge machine is outer, the breaking that can in breaking of ternary device, burn away, this just suffices to show that internal-combustion engine except that internal-combustion, also has external-burning (burning in the exhaust piping).Exhaust process burning before the external-burning is objective reality more just.Exhaust burning and later burning all are invalid burnings.Invalid burning is the first loss of internal-combustion engine, overcomes invalid burning, equals to have promoted active combustion, has improved the combustion performance of internal-combustion engine.The acting active combustion is the core technology of internal-combustion engine.The quality of burning quality, the direct relation engine performance.How making the active combustion quality good, at first is that ignition speed is fast, density is high, intensity is big, just can make flame propagation diffusion fast, and combustion speed is fast, and burning capacity is big, and detonation pressure is big, and velocity of piston is fast, the rotating speed height, power is big, per kilowatt, hour, oil consumption is few.The exhaust burning reduces, and the pollution of discharge is few, energy-conserving and environment-protective.
Summary of the invention
The purpose of this utility model is exactly at the deficiencies in the prior art, and the internal-combustion engine of a plurality of plug ignitions of a cylinder is provided.
For achieving the above object, the utility model adopts following technological scheme:
The internal-combustion engine of a plurality of spark plugs of an a kind of cylinder, comprise cylinder, cylinder head, ignition system, it is characterized in that: described internal-combustion engine is a petrol engine, described each independently be provided with at least 2 spark plugs on the cylinder head above the cylinder, spark plug is connected with ignition system.
In the petrol engine in internal-combustion engine with 1 spark plug, increase spark plug, spark plug internal-combustion engine promoted be a plurality of spark plug internal-combustion engines, during internal combustion engine, the ignition system powerful spark that glimmers, make the fuel fire that itself is easy to catch fire swift and violent more fast, under the constant situation of ignition intensity, increased igniting density and intensity, thereby improved velocity of propagation of flame, improve velocity of combustion, obtain perfect combustion more.Improve acting active combustion rate, improve power.Reduce the invalid rate of combustion of exhaust, reduce pollution emissions energy-conserving and environment-protective.
When described internal-combustion engine is petrol engine, 2 spark plug symmetries be arranged on each independently on the cylinder head of cylinder top.
In combustion engine cylinder head bottom combustion chamber scope, to the cylinder head overp0unch, 2 above spark plugs of design and installation, promote various internal-combustion engine catch fire dynamics, density, intensity, improve velocity of propagation of flame, improve velocity of combustion, improve acting active combustion rate, improve power, energy saving.Reduce invalid rate of combustion, reduce pollution emissions, environmental protection society.
Described ignition system is made of distributor, spark coil, signal emitter, switch, storage battery, spark plug is connected with distributor, and distributor is connected with spark coil, and fire coil is connected with signal emitter, signal emitter is connected with switch, and switch is connected with storage battery.
The utility model is intended to improve internal-combustion engine active combustion rate, reduces the invalid rate of combustion of internal-combustion engine.Energy saving, environmental protection society.Improve each combination property of internal-combustion engine simultaneously.According to burning primary condition (air fuel ratio, degree of mixing (degree of atomization), time, temperature) inference.Under the identical situation of combustion condition, a plurality of plug ignition devices are provided, make when igniting, multi-point and wide-ranging power is strong, the density of catching fire height, speed is fast, and flame propagation is fast, and velocity of combustion is fast, increases with burning capacity in the equal time.Acting active combustion rate improves, and power improves.The invalid rate of combustion of exhaust simultaneously reduces, and disposal of pollutants reduces.
The beneficial effect of the internal-combustion engine of a plurality of spark plugs of an a kind of cylinder of the utility model is, improves internal-combustion engine catch fire density and intensity, make multi-point and wide-ranging when catching fire, power is strong, reach that to improve the wide speed of catching fire fast, improve velocity of propagation of flame, improve the velocity of combustion purpose, thereby obtain burning more completely, working stroke active combustion rate improves, and power improves, energy saving, kilowatt-hour oil consumption unit of power calculates and will reduce, the invalid rate of combustion of exhaust stroke reduces, and exhaust emission reduces, environmental protection.
