Description
Technical field:
The utility model belongs to gasoline engine ignition system and application.
Background technique:
Petrol engine uses in traffic such as automobile, motorcycle, motive power machine equipment extensively, consumption is huge and just will scrap and renew in per ten years substantially, especially huge in its market capacity and demand, develop the modern society that many developing countries and regions such as China rapidly popularize automobile, prospect is extremely wide.
But the safe and reliable startup of petrol engine is a difficult problem with igniting always.This mainly be because its storage battery (being commonly called as storage battery) capacity and life-span that drives Starter all extremely limited, and be in complete state of rest without any being used to power because of motor when starting, need Starter, in other words be exactly to need storage battery to provide powerful power just can overcome stiction to enter motion state, and improve movement velocity gradually, and storage battery is at full capacity even hard service substantially in this process, particularly significantly increase resistance to motion in cold environment ignition difficulties such as winters and because of the stickiness of cold machine oil heightens, these factors all cause the bigger ignition system of resistance to be difficult to be zero substantially and almost consume the required energy of Starter competition igniting that storage battery is all exported electric energy with resistance, the required voltage of particularly lighting a fire, and when voltage be reduced to about 10 volts or when following spark very weak, even there is not spark and difficulty is successfully lighted a fire with ato unit at all, this just needs to continue ato unit, that is continue to make the discharge work of storage battery overburdening and battery tension is further fast reduced, provide the required normal voltage of igniting and more difficult successful ignition trigger with regard to more difficult, thereby form vicious circle, and storage battery is scrapped rapidly and significantly increased environmental pollution and renew user cost; When being fuel with rock gas and renewable energy sources such as ethanol or ethanol vapor wet goods, because of very difficult and gasoline vaporising vapour phase ratios such as concentration, winter, success starting ignition meeting doubly felt difficult, if renewable energy sources content is higher, for example 30% above ethanol petrol igniting is just difficult more, even can not light a fire at all, proportion of ethanol only dares to add very low 10% and one of major reason in the pilot process in very little scope such as some areas, the Three Eastern Provinces only in Here it is the present ethanol petrol of China, even if in developed country and regional ethanol adding proportion only 20%, highest level is about 30%, is difficult to improve again.
The design work voltage of storage battery only is 12 volts, completely newly the ceiling voltage of battery also only is 12.5 volts, aforementioned ignition voltage must reach 12 volts, be lower than 10 volts of then very difficult igniting, that is ignition voltage allow very narrow between the fluctuation zone, only be about 2 volts, that is to say the requirement of having only new battery could ensure igniting institute's energy requirement and voltage basically, and new battery can cause the factor life-span of ignition difficulties extremely short with following series equally because of above-mentioned cold, fuel etc.Though the generator of Automobile Design is 14 volts to charge in batteries voltage, but the rotating speed of generator is extremely slow when starting, may not reach this design voltage, but it is on the contrary: generator, fan and Starter etc. are the same will to consume the electric energy that a large amount of bases just are not enough to provide synchronously the storage battery of igniting electric energy and voltage, thereby further reduce the igniting electric energy especially voltage supply and be difficult to start, or because of significantly, high frequency ground prolongs starting time, make the big electric current overdischarge of storage battery and produce high heat and make electrode substance come off sex change even fusing distortion short circuit etc., make battery capacity and exert oneself greatly and reduce and significantly reduce the life-span, damage in advance or scrap, under a lot of situations even occur making the irreversible at once damage of the storage battery that should also have suitable ordinary life (be reduced to be irreversible damage below 10 volts for the voltage of 12 volts of batteries such as automobile) because of ignition difficulties starts repeatedly, though such battery can also drive rotations such as Starter, but can't ensure ignition voltage again during because of startup, in fact can only scrap in advance, even cast anchor because of lighting a fire, the influence trip, traffic and safety also influence national automobile industry development and the new energy especially enforcement and the progress of the great state basic policies of series such as application of renewable energy sources.
Obviously, if can ensure particularly voltage of igniting electric energy, above-mentioned all difficult problems just can both be readily solved.
ZL02133874.4 automobile and ship machinery petrol engine environmental protection starting ignition storage battery mandate patent of invention, take to provide an and price identical small battery etc. less than main storage battery 1/10 with main storage battery voltage, thereby not only solved ignition voltage and electric energy overcome storage battery aging and when starting ignition voltage not enough and be difficult to ensure the difficult problem of successfully lighting a fire with electric energy, also solved the igniting high pressure be fed back into car load low-voltage circuit and electrical equipment, especially with the car accurate electrical equipment of costliness such as global position system, computer, phone and audio visual system etc.; Utilize the electric energy that generator and main storage battery promptly start storage battery from the unidirectional charging of the little storage battery of trend and can be the circuit and the electrical equipment discharge of the electric energy of little storage battery beyond ignition system, and utilize diode the internal resistance pressure drop, make the charging voltage of little storage battery can little storage battery be avoided because of overcharging damage a little less than the voltage of generator and main storage battery all the time; But the limited electric current [strength of diode internal resistance and little storage battery all restriction point thermoelectricity flows through and burning out greatly and frequently that igniting is got an electric shock as platinum sheet and comprise that parking forgets to pull out ignition key and promptly forget to close serial difficult problems such as the spark coil of ignition switch is overheated, and look into new substantive examination and income world authoritative journal WPI-world patents index etc. and be better than Nippon Storage Battery Co., Ltd's design and adopt two big capacity and the high storage battery of price through Patent Office of State Intellectual Property Office is legal, damage back environmental pollution and user cost all increase to twice and lose more than gain, and nonreactive high pressure feedback endangers relevant patents such as function.But ZL02133874.4 also has deadly defect promptly the same with main storage battery, also can be constantly old and feeble, damage and cause ignition function and working state to cause in the full exhaust of engine operating condition shakiness, burning the dirty composition of ring and content significantly increases, and significantly increase oil consumption and reduce output power as the weak shakiness of fire, essential constantly replacing is polluted and user cost thereby also can increase certain environment.Though but little its macroscopic view and the consequence that adds up are very important equally this environmental pollution that increases for damaging with main storage battery of the single car of microcosmic and the user cost.
Summary of the invention:
Be exactly total the utility model is for addressing the above problem and for one inventive concept, adopt DC voltage-stabilizing input, self oscillations, interchange or direct current output point ignition source to select the application of a kind of Selfoscillatory AC/DC ignition power source for gasoline engine in yacht that designs with the technological scheme that combines
Beneficial effect of the present invention is that advantage is the low tension automatic voltage regulation that is difficult to ensure the storage battery of successfully lighting a fire storage battery is especially old and feeble or that scrap to become self required operating voltage and adjustable, automatically boost to the required 12-14 volt of igniting optimum voltage interval again, and the igniter high-tension coil is by the positive feedback high pressure very big to vehicle-mounted low-voltage electrical apparatus destructiveness of generations such as iron core induction, because of the present invention's use is high frequency magnetic core and the low pressure vibration independent current source isolated with storage battery, and its magnetic core, oscillistors etc. all have multiple weakening to igniter feedback voltage, stop and buffer action, use anti overvoltage circuit and components and parts so need not to resemble again the ZL02133874.4, also needn't resemble and re-use catching diode restriction initial firing current the ZL02133874.4, because of the limited input of its existing vibration and voltage stabilizing triode and multiple effective restriction of output power and oscillation transformer magnetic core chokes etc.
The present invention is not only because of circuit and the simple work safety of components and parts; reliably; and need not to increase any battery; also can be reduced to below 10 volts even 6 volts of igniting that can both very successfully assure success at battery tension; and regulate control ignition automatically between permission of 12-14 volt and optimum voltage; and when battery tension drops to below 10 volts, scrap because of not ensureing that igniting has belonged to as previously mentioned; drop to 8 volts or belonged to thorough damage when lower and can not rotate Starter more at all; as seen the present invention can not only make storage battery reach capacity working life; even in this case still can be by using wind or the smooth ato unit of go-cart mode with emergency; and can after startup, utilize the storage battery that non-big electric current overdischarge is damaged with the car generator to charge to make it recover normal level substantially, this forgets to close electric switch or long-term (about 3-6 month when stopping; fixation pause time spent storage battery situation) stops using that to fail a large amount of private cars and the environmental protection of charging in time again all be a Gospel undoubtedly.
The voltage stabilizing input scheme is corresponding to the voltage stabilizing output scheme, with the obvious advantage for ignition power source for gasoline engine: the voltage stabilizing input can stably be provided the vibration electric energy and be satisfied the especially demand of voltage of output point thermoelectricity by the low storage battery of voltage separately, because of the low storage battery of voltage is providing tens of even is additionally providing that to count Ampere currents with respect to the required 1-of igniting not difficult during up to a hundred amperes of inrush currents, difficult is, and to promote the voltage of initial firing current low, voltage stabilizing output is too poor or/and energy shortage then is difficult to accomplish separately this point as oscillatory stability, but this but is igniting key of success place.
Self oscillations exchange the output point ignition source with respect to direct current output igniting have that circuit is simple, components and parts are few, cost is low, so the multi-faceted igniting of many sparks can ensure and once light with sufficient combustion the few and fuel saving of environmental pollutants in the exhaust, but only be fit to mechanical contact such as traditional platinum contact ignition switch, then inapplicable to the ignition switch of necessary DC electrical source such as electronic ignition switch.
Self oscillations direct current output point ignition source is applicable to all igniters, but because of direct current in a light-off period be ignition switch closed with turn-off once can only produce an alternating electromotive force that is can only produce spark, so the no above-mentioned priming supply multi-faceted igniting advantage of many sparks in a light-off period that exchanges, and circuit complexity, components and parts are more, cost is corresponding also higher.
Obviously, it be advantage with respect to ZL02133874.4 is that ZL02133874.4 hardly matches, complete and complete innovation scheme that above-described the present invention designs the technical solution of employing and beneficial effect, and its novelty and practicability also are that ZL02133874.4 is difficult to mention in the same breath.
