Abstract
The present invention relates to a kind of starter motor for internal combustion engine applying to aviation unmanned plane and model airplane.Starter motor working principle of the present invention: the combustion gas in high pressure gas holder is by way of gas valve, be directly injected to combustion chamber of air cylinder to mix with the air of the inside, mixed gas is lighted blast and is promoted piston, piston drives engine running by driving mechanism, and piston rebounds playback by elastic device (such as spring) afterwards.Doing work at piston and rebound playbacks in this upper and lower stroke, as common two-stroke internal-combustion engine, completes exhaust and the air inlet of firing chamber simultaneously.The more traditional motor driven starter structure of this starter motor is simpler, and weight is lighter and handier, is especially applicable to SUAV.
Description
Technical field
The present invention relates to a kind of starter motor for internal combustion engine, particularly relate to a kind of starter motor for internal combustion engine applying to unmanned vehicle.
Background technique
The large-scale unmanned plane of Current internal combustion engines engine mainly carries the motor driven starter be made up of motor, reduction gear, battery.This starter motor requires higher to motor and the power of battery, and the power of starter motor and battery must be directly proportional to engine power, and therefore weight and volume is all larger.SUAV due to load-carrying limited, majority does not carry starter motor, cannot reignition after engine flame-out in flight.Design one is lightweight, volume is little, the simple starter motor of structure is object of the present invention.
Its essence of motor driven starter is that mechanical energy is to start engine by electric energy conversion.Innovation main points of the present invention are to jump out this thinking circle of utilization " electric energy ", use chemical energy, are specially: use the energy of fuel gas buring blast to change into mechanical energy and start engine.In simple terms, a kind of starter motor of internal-combustion engine is started exactly with gas internal-combustion engine.
The analysis of feasibility: combustion gas is taken as fuel when being directly used in piston type engine, the requirement of high rotating speed and persistency work, the lubrication of engine and heat radiation are problems needing to solve.But starter motor only needs of short duration burst work, working environment is simple, and therefore combustion gas applies to starter motor, and its structure is simpler light and handy.
Summary of the invention
Starter motor working principle of the present invention: the combustion gas in high pressure gas holder is by way of gas valve, be directly injected to combustion chamber of air cylinder to mix with the air of the inside, mixed gas is lighted blast and is promoted piston, piston drives engine running by driving mechanism, and elastic device (such as spring) helps piston to rebound playback afterwards.Doing work at piston and rebound playbacks in this upper and lower stroke, as common two-stroke internal-combustion engine, completes exhaust and the air inlet of firing chamber simultaneously.
Based on the consideration simplifying air cylinder structure and the rarefaction of air of adaptation High Altitude UAV working environment.Also can carry a hyperbaric oxygen gas tank again, oxygen and combustion gas are lighted after spraying in the lump and mixing in combustion chamber of air cylinder.
starter motor of the present invention mainly comprisescylinder, piston, high-pressure gas tank, air valve assembly, ignition module, driving mechanism, spring, combustion gas in high-pressure gas tank is ejected in the firing chamber of cylinder through air valve assembly and promotes piston after ignition through driving mechanism transmission engine, playback after spring makes piston do work.This starter motor is lightweight, volume is little, structure is simple, is more suitable for unmanned plane uses than traditional motor driven starter.
Cylinder has suction port, exhaust port, scavenging air belt.Suction port is provided with air pressure valve, opens air-breathing, close during descent of piston during piston stroking upward.During descent of piston, fresh air flows to firing chamber from the air chamber below piston through scavenging air belt.
Be equipped with the starter motor of oxygen tank, its cylinder can not establish scavenging air belt.
Air valve and ignition module comprise spark plug, gas gasifier, air valve assembly and corresponding Valve controlling and firing circuit, and gas gasifier is the element (capillary vessel on such as gas lighter) will sprayed after liquid fuel gasification.Air valve assembly is used for controlling air inflow, the proportions of ingredients of mixed gas in adjusting cylinders firing chamber.
Driving mechanism is the general designation of various mechanical assemblys piston kinetic energy being delivered to engine output shaft, use a kind of elastic element (such as spring) to make piston playback after acting, a unilateral bearing between driving mechanism and engine output shaft, must be had to hinder engine work to avoid starter motor.Driving mechanism includes but not limited to following several scheme.
one,rack-driving scheme: by be fixed on piston base tooth bar, to engage with tooth bar and the gear be enclosed within engine output shaft forms, the gear center of circle is fixed with unilateral bearing, and in one end of tooth bar, cover has spring to make piston playback.
two,dragline-transmission scheme: this is a kind of scheme stay cord of current conventional hand starter being connected to this starter motor piston.Comprise bracing wire and reel, reel center of circle cover has unilateral bearing, and spiral wheel case has clockwork spring to make bracing wire and piston playback, and piston is fixed in bracing wire, and leading block can be used to help the layout of bracing wire.
Three, hydraulic transmission scheme: hydraulic transmission is based on two kinds directly on hard transmission schemes above.Object is by the cylinder and piston of starter motor away from engine, is convenient to the layout of starter motor on unmanned plane like this, better the center of gravity of allotment unmanned plane.Such as on the basis of scheme one, the kinetic energy of piston by hydraulic power transmission to tooth bar.
accompanying drawing illustrates:
Fig. 1 is the starter motor adopting the hard transmission of rack and pinion;
Fig. 2 is used to the air valve assembly controlling combustion gas or oxygen lancing amount;
embodiment:
As shown in Figure 1, in figure, 1 is air valve assembly, and 2 is the suction ports being with air pressure valve, and 3 is gears that cover has unilateral bearing, and 4 is the springs helping piston to playback, and 5 is cylinder scavenging air belts.
As shown in Figure 2, in figure, 201 connect gas tank, and 202 is air valves, and air valve is controlled by Servo-controller, and during work, valve is first opened and then closed, and can light a fire by pilot spark plug during closedown, and 203 are used to the tolerance pin controlling air inflow, and 204 is blast nozzles.
