Abstract
The utility model requests to protect a dual-fuel ignition system for a motorcycle engine, which comprises an engine magneto, an igniter, a high-voltage coil and a spark plug, and is characterized in that gasoline ignition magnetic steel is arranged in the position of a gasoline ignition advance angle on a rotor of the engine magneto, and a gasoline ignition sensor is correspondingly arranged on an identical circular plane of a stator; natural gas ignition magnetic steel is arranged in the position of a natural gas ignition advance angle on the rotor, and natural gas ignition magnetic steel is arranged on the identical circular plane of the stator corresponding to the rotor; signal lines of the gasoline ignition sensor and a natural gas ignition sensor are connected with the igniter through a single-pole double-throw switch. By adopting the dual-fuel ignition system, magnetic steel and two sensors are arranged on the magneto, so as to ensure that different ignition advance angles are obtained when different fuels are used, and achieve the purposes of fully burning the fuel, reducing pollution emission, saving energy resources, and improving power.
Description
Technical field
The utility model relates to the motorcycle engine ignition system.
Background technique
The motor of automobile, motor tricycle all has the dual-fuel situation that needs at present, mainly is with gasoline and rock gas (being called for short CNG in the past).Because the octane value and the CNG of gasoline are different, cause when another kind of fuel is used in same motor conversion, if do not take necessary improvement, it is unreasonable firing time to occur, produces degradation problem under fully burning of fuel, engine overheat, the power.
Summary of the invention
The purpose of this utility model is to propose a kind of double fuel motorcycle engine ignition system, when using different fuel at the deficiency of present double fuel operation motorcycle engine existence, with different ignition advance angles,, reduce blowdown to guarantee the abundant burning of fuel, energy saving improves power.
The technical solution of the utility model is as follows:
A kind of dual-fuel motorcycle engine ignition system, include motor magnetogenerator, igniter, high-tension coil and spark plug, the sensor signal lines tie point firearm of motor magnetogenerator, igniter is electrically connected high-tension coil and spark plug again, be provided with gasoline igniting magnet steel in the epitrochanterian gasoline ignition advance angle position of described motor magnetogenerator, the same disk of stator is provided with the gasoline ignition detector accordingly; Epitrochanterian natural gas fired advance angle position at described motor magnetogenerator is provided with a natural gas fired magnet steel, on the same disk of the stator corresponding with it natural gas fired magnet steel is set; The signaling line of described gasoline ignition detector and natural gas fired sensor is by a single-pole double-throw switch (SPDT) tie point firearm.
We know that the motor work done is to finish because fuel in combustor inner cylinder, blast acting, promotes piston up-down.The required time Δ t of various full combustion of fuel is different.If gasoline mixes the full combustion of gas needed time that produces with atmosphere be Δ t1, rock gas (CNG) mixes abundant period of combustion with atmosphere be Δ t2.Obvious Δ t2＞Δ t1 (whether oxygen is enough when not considering to mix, and in same volume).Hot mechanism prosecute prosecution is told we Δ t and is guaranteed by the advance angle θ of piston motion to budc.Guarantee during hot machine manufactures and designs that when engine speed rose, θ shifted to an earlier date gradually, but do not consider fully the burn advance angle θ of different required change of different fuel.The motorcycle engine fire signal derives from magnetogenerator, this programme has been adorned a magnet steel and a sensor more on former magnetogenerator basis, promptly be provided with the magnet steel of two fire signals, and correspondence is provided with two sensors on position of stator, by switch, make different fuel obtain different initial ignition signals.
The utility model to guarantee obtaining different ignition advance angles when using different fuel, can both fully burn fuel to reach by two magnet steel and sensor are set on the magnetogenerator of ignition system, reduces blowdown, energy saving, the purpose of raising power.
Description of drawings
Fig. 1 is the structural representation of magnetogenerator;
Fig. 2 is the structural representation of ignition system.
Embodiment
Below in conjunction with accompanying drawing structure of the present utility model is elaborated:
This ignition system is made up of motor magnetogenerator, igniter 10, high-tension coil 11 and spark plug 12.Wherein the motor magnetogenerator as shown in Figure 1, magnetogenerator stator 1 is fixed on the hood 5, rotor 2 is installed on the rotor shaft 8, by its driven rotary.Be fixed with respectively on two different disks on the rotor 2 of magnetogenerator, be separately positioned on gasoline ignition advance angle position and natural gas fired advance angle position, be provided with gasoline ignition detector 7 and natural gas fired sensor 6 at magnetogenerator stator 1 accordingly.When engine running, rotor shaft 8 drives rotors 2 rotations, whenever circles, and gasoline igniting magnet steel 4 and natural gas fired magnet steel 3 cut gasoline ignition detector 7 and natural gas fired sensor 6 respectively once, produce fire signal respectively.Because gasoline igniting magnet steel 4 and gasoline ignition detector 7 are on a disk, natural gas fired magnet steel 3 and natural gas fired sensor 6 are on another disk, magnetogenerator whenever circles, and gasoline ignition detector 7 and natural gas fired sensor 6 all can only produce a fire signal.
Fig. 2 has shown the ignition system principle, and the signaling line of gasoline ignition detector 7 and natural gas fired sensor 6 is by single-pole double-throw switch (SPDT) 9 tie point firearms 10.When using gasoline, single-pole double-throw switch (SPDT) 9 is in the K1 position, and gasoline ignition detector 7 is connected with igniter 10, natural gas fired sensor 6 disconnects, the signal that gasoline ignition detector 7 produces is given igniter 10, makes high-tension coil 11 produce ignition energy, makes spark plug 12 discharge ignitings.When with rock gas (CNG), double-throw single knife switch 9 is connected natural gas fired sensor 6 and igniter 10 in the K2 position, and natural gas fired sensor 6 produces fire signal and gives igniter 10, makes high-tension coil 11 produce igniting, makes spark plug 12 discharge ignitings.
In this scheme, used the same point firearm, igniter itself rises and the not change in advance of nearly angle with speed.Promptly the advance angle of engine speed does not at this moment change.Change has taken place in total advance angle during just with CNG.
In the reality, more perfect in order to pursue, the ignition advance angle under each rotating speed also can adopt the igniter at two nearly angles of difference.
