Description
The utility model is the ignition mechanism that a kind of motor is used, and mainly is applicable to various types of multi-cylinder petrol engines.
Existing multi-cylinder petrol engine generally adopts distributor as ignition mechanism, and the inner closure that relies on the platinum contact of distributor makes spark coil produce high pressure, lights a fire in order to countercylinder.Because the platinum contact is frequently closed, when electric current passes through, producing electric arc ablates contact oxidation, thereby hindered passing through of electric current, and then the generation of influence igniting high pressure, make motor produce the phenomenon of catching fire, cause and be short of power, oil consumption increases, decreased performance, and the driver has to often platinum be keeped in repair and changes.
The purpose of this utility model is exactly the deficiency at existing ignition mechanism, designs a kind of new ignition mechanism, and the platinum contact in the cancellation distributor is avoided because of catching fire that pitting of contact causes, and power descends, and improves the engine ignition reliability.
The utility model is to realize like this.Replace the platinum contact as contactless switch with the magnetosensitive Hall element, existing distributor assy inside is transformed, cancel original platinum contact mechanism, installing sensor disk on original camshaft, its position is at former cam position, the magnetic steel ingot corresponding with engine cylinder number evenly distributes on the disk outer circular edge, a Hall element bracket tray vertical with camshaft is set in the distributor assy housing simultaneously, Hall element is fixed on the position corresponding with the sensor disk on the pallet, the Hall element lead-in wire is drawn from the distributor edge, connects signal amplification circuit and spark coil.The sensor disk is a flat-shaped cylindrical body, has uniform magnet steel groove on the cylindrical body outer circle wall, and magnetic steel ingot is embedded in the groove.The Hall element support is double-deck concentric structure, and bottom and distributor body are connected, and the upper strata can be rotated around the center of circle, has the degree of vacuum adjustable lever to connect the hole on it, and when degree of vacuum changed, the upper strata can be rotated thereupon, adjusts ignition advance angle.Signal amplification circuit is composed in series by two gate circuit and amplification circuits that contain not gate; use the differentiator coupling between two gate circuits, the input end of first gate circuit and second gate circuit is connected to the machine oil under-voltage protecting circuit of being made up of integration circuit and auxiliary element and the protective circuit of shutting down automatically respectively.Differentiator can the control ignition coil the power on/off dutycycle, promptly the spark coil power-off time is shorter, guarantees that it has enough rechargeable energies; The machine oil under-voltage protecting circuit and automatically the shutdown protective circuit can guarantee under-voltage or to stall and do not have under the situation of shut-off circuit at machine oil, through certain hour automatic delay function circuit, with protection motor and spark coil.Driving camshaft when the distributor transmission shaft rotates rotates, thereby make the sensor disk rotation on the camshaft, every block of magnet steel turns over the Hall element surface in turn on the disk, makes Hall element produce trigger signal, be transported to signal amplification control circuit through lead, the feed point fire coil produces the igniting high pressure.
The utility model is compared with existing platinum contact igniter, has that ignition performance is reliable and stable, spark energy is big, be applicable to various rugged environment, make simple, easy for installation, maintenance-free characteristics.
Accompanying drawing 1 is the utility model distributor assy structural representation.
Accompanying drawing 2 is the utility model signal amplification circuit electrical schematic diagrams.
The utility model is to replace original platinum contact with magnetosensitive Hall element (9), whole igniter is by distributor assy, signal amplification circuit and spark coil L constitute, existing distributor assy inside is transformed, cancel original platinum contact mechanism, go up installing sensor disk (7) at original camshaft (8), sensor disk (7) is a flat-shaped cylindrical body, have uniform magnet steel groove on the cylindrical body outer circle wall, magnet steel (6) is embedded in the groove, magnet steel (6) piece number is identical with engine cylinder number, four-cylinder is with four, six cylinder machines are with six, a Hall element bracket tray (4) vertical with camshaft (8) is set in distributor assy housing (2) simultaneously, Hall element (9) is fixed on the position corresponding with sensor disk (7) on the pallet, the lead-in wire (10) of Hall element (9) is drawn from the distributor edge, connects signal amplification circuit and spark coil.The Hall element support is double-deck concentric structure, and bottom (3) is connected with distributor body (2), and upper strata (4) can rotate around the center of circle, have the degree of vacuum adjustable lever to connect hole (5) on it, and when motor degree of vacuum changed, upper strata (4) can rotate thereupon, adjusts ignition advance angle.Signal amplification circuit is composed in series with two NOR gate and amplification circuit, and with differentiator B coupling, an input end of first NOR gate is connected to the machine oil under-voltage protecting circuit A that is made up of not gate and integration circuit and discharge diode between two NOR gate; An input end of second NOR gate is connected to by not gate and integration circuit and is connected in parallel on the automatic shutdown protective circuit C that ohmically diode is formed.Driving camshaft (8) when distributor transmission shaft (1) rotates rotates, thereby make sensor disk (7) rotation on the camshaft (8), the last every block of magnet steel of disk (7) (6) turns over Hall element (9) surface in turn, make Hall element (9) produce trigger signal, be transported to signal amplification control circuit through lead (10), feed point fire coil L produces the igniting high pressure.
