Description
Technical field
This utility model is related to gas engine control field, more particularly to a kind of oil-gas two-way vehicle ignition control electricity
Road.
Background technology
Existing oil-gas two-way fuel automobile, it is when its electromotor is under combustion gas pattern, dynamic under gasoline mode in order to reach
Power performance, needs are shifted to an earlier date on the basis of original gasoline ignition angle, and prior art is by changing engine crankshaft position
Confidence number, has to former machine gasoline electronic control unit (Electronic Control Unit, ECU) and can demarcate time delay
The emulation signal of time, after gasoline electronic control unit (Electronic Control Unit, ECU) is further according to phase change
Emulation signal provide the ignition signal of angle on target, but there are some problems in this mode：Above-mentioned emulation signal is also by shadow
The port timing of electromotor, and the phase place of change crankshaft-position signal are rung, crankshaft-position signal and cam phase letter certainly will be caused
Phase deviation between number, ignition control device are reported to failure warning system after detecting the deviation so that automobile is entered walks lamely
Pattern.
Utility model content
To solve above technical problem, this utility model provides a kind of oil-gas two-way vehicle ignition control circuit.
Ignition coil power supply, ignition coil, crankshaft position sensor, gasoline electronic control unit and ignition control unit；
The ignition coil power supply is connected with the ignition coil, is that the ignition coil is powered；
The gasoline electronic control unit first end is connected with the ignition coil, and the second end is sensed with the crank position
Device connects, for the ignition signal of output engine；
Second end of the crankshaft position sensor is connected with the ignition control unit first end, for exporting described sending out
The crankshaft-position signal of motivation；
The second end of the ignition control unit is connected with the ignition coil, for blocking the gasoline electronic control unit
With the control circuit of the ignition coil, and the ignition signal and the crankshaft-position signal are gathered, and the igniting to gathering
Signal and crankshaft-position signal are carried out processing and draw new ignition signal, and the new ignition signal drives the ignition lead to punctuate
Fire.
Beneficial effect：
The oil-gas two-way vehicle ignition control circuit that this utility model is provided.By ignition control unit in gasoline electronics control
During unit output ignition signal processed, the control circuit of gasoline electronic control unit and ignition coil is blocked, so as to block gasoline electricity
Sub-control unit is transferred to ignition coil ignition signal, and ignition control unit collection ignition signal simultaneously gathers this moment electromotor
In crankshaft position sensor output crankshaft-position signal, and the crankshaft-position signal processed draw the igniting being currently needed for
At the moment, while driving the ignition coil according to new ignition signal, new igniting is the angle of ignition for changing electromotor
The signal of degree, so as to the ignition angle for increasing electromotor can reach the power performance under gasoline mode, it can thus be seen that this reality
With a kind of control system of change engine ignition angle of new offer, former petrolic port timing will not be changed,
So as to remain the nominal data inside former engine controller to greatest extent.
Description of the drawings
Fig. 1 is that system structure of the present utility model illustrates schematic diagram.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than it is all real
Apply example.Based on the embodiment in this utility model, those of ordinary skill in the art under the premise of creative work is not made, institute
The every other embodiment for obtaining, belongs to this utility model protection domain.
A kind of Control system architecture such as Fig. 1 of change engine ignition angle shown in this utility model
It is shown.Including：Ignition coil power supply, ignition coil, crankshaft position sensor, gasoline electronic control unit and igniting
Control unit；Wherein, ignition coil power supply is connected with ignition coil, is that the ignition coil is powered；Gasoline electronic control unit
First end is connected with ignition coil, and the second end is connected with crankshaft position sensor, for the ignition signal of output engine；Bent axle
Second end of position sensor is connected with ignition control unit first end, for exporting the crankshaft-position signal of the electromotor；
The second end of ignition control unit is connected with the ignition coil, for blocking ignition signal, and receives crankshaft-position signal, and right
The ignition signal of collection is carried out processing and draws new ignition signal, and new ignition signal drives the ignition coil.
Specifically, in combustion gas pattern, engine ignition exports ignition signal by gasoline electronic control unit to vehicle,
Ignition control unit blocks gasoline ECU with the control circuit of ignition coil so as to blocking ignition signal and gathering the ignition signal,
Obviously, block gasoline electronic control unit and ignition coil control circuit be truncated after, then gasoline electronic control unit output
Ignition signal cannot just be transferred in ignition coil, then this moment point live wire circle misfires, at the same ignition control unit collection
The crankshaft-position signal of the crankshaft position sensor output in electromotor, ignition control unit is according to the angle in crankshaft-position signal
Degree signal of change present engine phase place and corner information, increase on the basis of gasoline electronic control unit control ignition angle
One offset (especially, offset needs driving, economy and the emission performance of comprehensive vehicle to draw), then pass through
Algorithm calculates current time of ignition, drive ignition coil igniting, so as to reach and the same dynamic property under gasoline mode
Energy.
It is more than that a kind of control system for changing engine ignition angle provided by the utility model has been carried out in detail
Introduce.Specific case used herein is set forth to principle of the present utility model and embodiment, above example
Illustrate that being only intended to help understands method of the present utility model and its core concept.It should be pointed out that general for the art
For logical technical staff, on the premise of without departing from this utility model principle, some improvement can also be carried out to this utility model
And modification, these improve and modification is also fallen in this utility model scope of the claims.
