Abstract
A kind of engine start control method, during motor reversely rotates, engine is rotated backward with motor, implements oil spout at the time of engine needs oil spout with n1 times of distributive value when rotating in the forward direction, wherein the n1 is the coefficient greater than 0 and less than 1.The present invention is by reducing distributive value, when avoiding excessively inverting, and inverting inside appropriate oil spout to air intake duct, forms oil film in air intake duct wall surface, when engine, which rotates forward, to be started, motor starting characteristic can be improved.
Description
Technical field
The present invention relates to a kind of automation equipment, especially a kind of engine start control method.
Background technique
Starting-generating all-in-one machine, is widely used in automobile.It is also at present more and more extensive in the application of motorcycle field.
Starting-generating all-in-one machine, now at least following two starting method:
A. it rotates forward after starting is obstructed and inverts, rotate forward (if rotating forward unsuccessful reversion → rotating forward again) after reversion again；
B. it first inverts, judge process is compression top center or exhaust top dead center, stops reversion after eligible, immediately
It rotates forward.
It is that quantitative oil spout and igniting are implemented according to the position of crankshaft rotation when EFI engine rotates in the forward direction.Generally all
It is that can just be inverted when sparking.If drive engine reversion, also carries out and rotate forward according to the position of crankshaft rotation and is same
The oil spout and igniting of amount, may be such that excessive engine invert, cause to invert it is out of control, so as to engine generate it is unfavorable
Influence.
Summary of the invention
In order to overcome drawbacks described above, the present invention provides a kind of engine start control method, can be avoided excessive reversion
To mitigate the adverse effect to engine.
The present invention is to solve technical solution used by its technical problem: a kind of engine start control method, In
During motor reversely rotates, engine is rotated backward with motor, with n1 times of forward direction rotation at the time of engine needs oil spout
Distributive value when turning implements oil spout, wherein the n1 is the coefficient greater than 0 and less than 1.
As a further improvement of the present invention, during motor reversely rotates, the ignition energy is normal ignition energy
N2 times of amount, the n2 are the coefficient greater than 0 and less than 1.
As a further improvement of the present invention, the engine is a kind of starter-generator.
As a further improvement of the present invention, the engine first reversely rotates before rotating in the forward direction.
As a further improvement of the present invention, the engine includes the motor that driving motor rotated and controlled electric power generation
Control device, the Injection Control device in regulation moment injection regulation oil mass and the ignition control dress in the igniting of regulation moment
It sets.
The beneficial effects of the present invention are: the present invention is when driving motor inverts engine, without quantitative oil spout, but
It on the basis of rotating forward distributive value, is multiplied by one and is greater than 0 and the coefficient less than 1, that is, when reversion, reduce distributive value, avoid excessively
Reversion, and inside appropriate oil spout to air intake duct, oil film is formed in air intake duct wall surface, when engine, which rotates forward, to be started, can be improved
Motor starting characteristic.
Specific embodiment
A kind of engine start control method, during motor reversely rotates, engine is rotated backward with motor, is being sent out
Motivation needs to implement oil spout at the time of oil spout with n1 times of distributive value when rotating in the forward direction, wherein the n1 is greater than 0 and less than 1
Coefficient.The present invention is when driving motor inverts engine, without quantitative oil spout, but on the basis for rotating forward distributive value
On, it is multiplied by one and is greater than 0 and the coefficient less than 1.When reversion, distributive value is reduced, avoids excessively inverting, and appropriate oil spout is to air inlet
Inside road, oil film is formed in air intake duct wall surface, when engine, which rotates forward, to be started, motor starting characteristic can be improved.
Preferably, during motor reversely rotates, the ignition energy is n2 times of normal ignition energy, and the n2 is
Coefficient greater than 0 and less than 1.It is to avoid inverting out of control, excessively reversion to control the circle number of reversion in suitable range,
Malcombustion may be generated in muffler for motor, cause catalyst exception scaling loss.Excessively reversion can also play engine
Motivation structure generates inordinate wear, and starter mechanism is caused to break down.
Preferably, the engine is a kind of starter-generator, so that engine start be driven to rotate, and is transported in engine
Turn Shi Fa electricity.
Preferably, the engine first reversely rotates before rotating in the forward direction.First reversion is equivalent to before engine rotating forward
A run-up so that engine be easier rotate start.
Specifically, the engine includes that driving motor rotates and controls the motor control assembly of electric power generation, providing
The Injection Control device of moment injection regulation oil mass and the ignition control device lighted a fire at the regulation moment.
The present invention is when driving motor inverts engine, without quantitative oil spout, but on the basis for rotating forward distributive value
On, it is multiplied by one and is greater than 0 and the coefficient less than 1, reduce distributive value, avoid excessively inverting.When reversion, appropriate oil spout to air intake duct
Inside forms oil film in air intake duct wall surface, when engine, which rotates forward, to be started, motor starting characteristic can be improved.
