Description
Technical field
The present invention relates to a kind of light/heavy oil pattern automatic conversion control methods.
Background technology
The relatively low ordinary diesel oil of fuel density and the relatively high heavy diesel fuel of fuel density can be used in marine engine,
In order to save cost, in blue water normally travel, marine engine uses heavy diesel fuel, and in offshore sea waters or will pull in shore
When, marine engine uses ordinary diesel oil.Thus above-mentioned marine engine can mating light/heavy oil converting device, thus to starting
Ordinary diesel oil or heavy diesel fuel are provided in the combustion chamber of machine, when engine uses ordinary diesel oil, set in engine control system
For light oil pattern（MDO patterns）, when engine uses heavy diesel fuel, it is set as heavy oil pattern in engine control system（HFO moulds
Formula）, under above two pattern, the alarm setting value of the parameters such as engine control system intermediate fuel oil pressure and fuel oil temperature is complete
It differs.
In the prior art, light/heavy oil converting device is used to the switching of ordinary diesel oil and heavy diesel fuel, completes light/heavy oil and turns
After the switching of changing device, then light/heavy oil Mode Feedback device is connected on the engine, i.e., on pipeline before entering into the combustion chamber
The signal of signalling means is fed back to engine control system by setting signal device, and operator feeds back according to above-mentioned signal, determine into
The fuel oil entered in engine chamber is ordinary diesel oil or heavy diesel fuel, and then, operating personnel manipulate engine control system and adopt again
With MDO patterns or HFO patterns.Aforesaid way needs on light/heavy oil converting device, increases light/heavy oil Mode Feedback device,
And artificial progress confirmation operation is needed, complicated line arrangement is not only increased, increases production cost, but also operate numerous
Trivial, the intelligent operation of engine can not achieve, also, the damage problem of manual operation or feedback device once occurs, can give hair
Motivation causes huge damage.
Invention content
The technical problem to be solved in the present invention is to provide a kind of light/heavy oil pattern automatic conversion control method, the light/heavy oil
Pattern automatic conversion control method can judge that the fuel oil entered in engine chamber is ordinary diesel oil or heavy diesel fuel automatically, from
And light oil pattern or heavy oil pattern are used in automatically controlled engine control system, the intellectualized operation of engine is realized, is kept away
The accidental injury of engine is exempted from.
In order to solve the above technical problems, light/heavy oil pattern automatic conversion the control method provided includes engine control
System and the operator control panel being connect with engine control system, it is characterised in that：It is provided with light oil in the engine control system
Timer is arranged in engine control system for pattern and heavy oil pattern, into the conveying oil pipe of engine chamber on be equipped with
The fuel temperature sensor being connect with engine control system, for detecting fuel oil into machine temperature, into engine control system
It is implanted into light/heavy oil pattern automatic conversion and controls program, by being operated in operator control panel, choose whether to start light/heavy oil mould
Formula automatic conversion controls program；
If not starting light/heavy oil pattern automatic conversion control program, engine control system uses light oil pattern；
If starting light/heavy oil pattern automatic conversion controls program, engine control system extraction is acquired from fuel temperature sensor
The fuel oil arrived into machine temperature numerical value, according to fuel oil into the numerical value situation of machine temperature and pass through after the judgement in interval time determine
Engine control system uses light oil pattern or heavy oil pattern.
When the numerical value of fuel oil into machine temperature is invalid numerical, engine control system uses heavy oil pattern；When fuel oil into
When the numerical value of machine temperature is Effective Numerical；
The Effective Numerical is less than particular value, starts timer, passes through the multiple of the first setting time intrinsic motivation control system
The numerical value of judgement fuel oil into machine temperature is smaller than particular value, and light/heavy oil pattern automatic conversion controls program to engine control system
System, which sends out signal, ensures that engine control system uses light oil pattern；
After the Effective Numerical is more than particular value, starts timer, pass through the more of the second setting time intrinsic motivation control system
The numerical value of secondary judgement fuel oil into machine temperature is all not less than particular value, and light/heavy oil pattern automatic conversion controls program to engine control
System processed, which sends out signal, ensures that engine control system uses heavy oil pattern.
The particular value is 80 DEG C.
It is big to there is Effective Numerical in any judgement in the multiple judgement of first setting time intrinsic motivation control system
In the particular value the case where, start timer reclocking until repeatedly Effective Numerical is smaller than particular value in judgement；Second setting
There is the case where Effective Numerical is less than particular value in any judgement in the multiple judgement of time intrinsic motivation control system, opens
Dynamic timer reclocking is until repeatedly Effective Numerical is all more than particular value in judgement.
First setting time is 5s, and the second setting time is 5s, judges that the frequency when Effective Numerical size is
0.1s/ times.
After the above method, steamer offshore sea waters when driving, the light/heavy oil pattern automatic conversion control can not be started
Processing procedure sequence, transmitter control system can use light oil pattern completely；After driving into blue water, the light/heavy oil can be started
Pattern automatic conversion controls program, is sent out according to fuel oil into the numerical value situation of machine temperature and by being determined after the judgement in interval time
Motivation control system uses light oil pattern or heavy oil pattern.Certainly, offshore sea waters when driving, light/weight can also be directly initiated
Oily pattern automatic conversion controls program, according to fuel oil into the numerical value situation of machine temperature and by being determined after the judgement in interval time
Engine control system uses light oil pattern or heavy oil pattern.Thus this method no longer need on the engine it is separately installed it is light/
Heavy oil Mode Feedback device reduces engine control system signal and inputs quantity, reduces engine peripheral accessory cost, carry simultaneously
The high safety operation performance and intelligent operation performance of engine.
