Description
Technical field
The present invention relates to the method for adjustment of a kind of gasoline natural gas flexible fuel engine angle of ignition and ignition energy, belong to
Engine control system technical field.
Background technology
For the gasoline natural gas flexible fuel engine reequiped and come from petrol engine, it is limited to repacking cost and changes
Difficulty is filled, the ignition system of former gasoline engine is typically still continued to use.When burning natural gas, due to the combustion characteristics of natural gas in itself,
So that same operating, angle of ignition when angle of ignition during burning natural gas is than burns gasoline is big, but can not pass through modification again
The igniting angular data of petrol system is to adapt to the burning of natural gas.
At present, most gasoline natural gas flexible fuel engines use one in the adjustment of ignition advance angle more
It is commonly called as the device of electronic spark advance device to intercept former engine crankshaft signals, and exports a new bent axle after phase offset
Signal, what gasoline engine ECU was received is crankshaft signal after phase offset, and the phase angle recognized with new crankshaft signal
Spend to perform igniting, by the angle for changing crankshaft signal phase offset, you can change the actual ignition angle of gasoline engine.Due to
Electronic spark advance device can not recognize engine load, therefore, and its angle adjusted to the angle of ignition is a fixed value, with a hair
Motivation, uses an angle of ignition adjustment magnitude.This method and technology is relatively easy, and repacking librarian use in market is filled after being also easy to.
But this angle of ignition adjustment mode has one, because when designing Engine ECU, crankshaft sensor is with sending out
Motivation ECU is in electromagnetic property, and needs are matched, when electronic spark advance device is connected on engine crankshaft signals and gasoline
Between ECU, the circuit in electronic spark advance device can be destroyed to a certain extent good between crankshaft sensor and former machine ECU matches pass
System, the minimum engine speed that causing ECU can recognize is enhanced, due to engine only after crankshaft signal is recognized ability
Enter the judgement of line phase, and then carry out oil spout and igniting, the raising of recognizable minimum speed can cause engine first in starting
At the time of secondary oil spout and igniting rearward, when starter dragging rotating speed is too low, in fact it could happen that the situation of rotating speed None- identified, directly
The starting performance of engine is had influence on, this is also the current dual-purpose combustion of gasoline natural gas that igniting adjustment is carried out using igniting advancing device
Expect that engine all starts the major reason of engine using gasoline.Meanwhile, current electronic spark advance device can only change engine point
Fiery angle, when natural gas is used, ignition energy still use the ignition energy under gasoline combustion, cause ignition effectiveness to reduce, shadow
Ring engine power performance and discharge performance.
Therefore, if a kind of new angle of ignition and ignition energy method of adjustment can be proposed, accomplish in the same of the adjustment angle of ignition
When, the matching relationship between crankshaft sensor and gasoline ECU is not influenceed, natural gas can be used to be started, then can be great
Improve the convenience using flexible fuel engine.Meanwhile, according to combustion of natural gas characteristic, changing the angle of ignition simultaneously, moreover it is possible to
Ignition energy is adjusted, then can preferably play natural gas performance, oil consumption is reduced, reduction discharge is significant.
The content of the invention
The present invention seeks to for above-mentioned the deficiencies in the prior art, propose a kind of gasoline natural gas flexible fuel engine point
Fiery angle and the method for adjustment of ignition energy.
The present invention solves technical problem and adopted the following technical scheme that：A kind of gasoline natural gas flexible fuel engine angle of ignition
With the method for adjustment of ignition energy, it includes：
S10, gasoline ECU are sent engine speed information and air- distributor pressure information to natural gas by CAN lines
ECU, natural gas ECU supply it to pattern information and sent by CAN lines to gasoline ECU；
S20, natural gas ECU table look-up according to engine speed information and air- distributor pressure information and obtain current working, and
When in natural gas pattern, angle of ignition adjustment angle and ignition energy adjusted value are calculated according to current working；When in gasoline
During pattern, angle of ignition adjustment angle and ignition energy adjusted value are set to 0；
The S20 angle of ignition adjustment angles calculated and ignition energy adjusted value are sent to by S30, natural gas ECU by CAN lines
Gasoline ECU；
S40, gasoline ECU receive natural gas ECU transmission angle of ignition adjustment angle and ignition energy adjusted value after, when in
During natural gas pattern, using the former gasoline angle of ignition of angle of ignition adjustment angle amendment, the former gasoline of igniting energy adjusting value amendment is used
Ignition energy value；When in gasoline mode, the former gasoline angle of ignition and ignition energy value are continuing with.
Optionally, the fuel delivery mode information is gasoline mode or natural gas pattern.
The present invention has the advantages that：The gasoline natural gas flexible fuel engine angle of ignition and ignition energy of the present invention
The method of adjustment of amount, under natural gas pattern, natural gas ECU is adjusted angle of ignition adjustment angle and ignition energy by CAN lines
Value is sent to gasoline ECU, gasoline ECU this angle of ignition adjustment angle and the former gasoline angle of ignition of ignition energy adjusted value amendment and point
Fiery energy value, due to not being related to using natural gas ECU adjustment crankshaft/camshaft signals, therefore will not destroy gasoline ECU and song
Electromagnetic property relation between axle/camshaft-signal sensor to match, does not interfere with the slow-speed of revolution gasoline ECU to crankshaft/camshaft
The identification of signal, therefore so that start engine with natural gas and be possibly realized, greatly improve ease of use；Meanwhile, day
Right gas pattern down-firing angle and ignition energy are all adjustable, and the performance of natural gas can be played to greatest extent, improve fuel-economy
Property, reduction discharge.
