Description
The present invention relates to a kind of Reciprocatory, piston type multi-cylinder body idol cylinder and count the fuel saving method and the device of field of internal combustion engine.
We know, vapour, diesel oil Reciprocatory internal-combustion piston engine in order to increase stability and power thereof, adopt the multi-cylinder body more at present, and even cylinder table structure is as cylinder numbers such as 4,6,8.
Can be present, count in the use of Reciprocatory internal-combustion piston engine at multi-cylinder body idol cylinder, often do not reach the rated power that internal-combustion engine is exported.Especially in the use of carrier, automobile, internal combustion locomotive, steamer, unloaded, underloading phenomenon often appear.We know, the internal-combustion engine rated output power is according to the maximum load of employing equipment and definite.Use at the equipment of carrier, internal-combustion engine is that maximum load, maximum resistance, max. climb slope, the maximum drawbar pull according to equipment selected design for use, when zero load, underloading appear in haulage device, during descending, certain residue output power should be arranged in the internal combustion like this.That is to say: haulage device, vehicle runnabilitys such as zero load, underloading, descending occur when using internal-combustion engine, when having surplus power to occur, haulage device, vehicle can be selected a low power internal-combustion engine for use.
Can be present, in the use of internal-combustion engine, especially on the haulage vehicle equipment of carrier, multiselect is counted the Reciprocatory internal-combustion piston engine with a powerful multi-cylinder body idol cylinder.Like this because each piston of multi-cylinder body internal-combustion engine is to work on same bent axle, vehicle is in order to reach certain travelling speed, internal-combustion engine under the certain situation of output speed, the vehicle zero load, underloading, heavily loaded used amount of fuel differs small.So how many fuel oils vehicle does not save when zero load, underloading, descending.
For example, internal-combustion engine comes to this in the application of automobile, and the speed of a motor vehicle is per hour, and in the time of 60 kilometers, zero load, underloading, heavily loaded used amount of fuel are more or less the same.
The objective of the invention is to propose a kind of multi-cylinder body idol cylinder and count the Reciprocatory internal-combustion piston engine changes output power according to contained load variations method and device thereof.By cylinder reducing oil saving method and device thereof multi-cylinder body even number Reciprocatory piston IC engine is carried out the fuel-economizing running, can save the 0-50% fuel oil.
Cylinder reducing oil saving method of the present invention and device, be according to the contained load variations of internal-combustion engine, multi-cylinder body idol cylinder is counted the artificial minimizing clutch release slave cylinder number of Reciprocatory internal-combustion piston engine, play and reduce the internal combustion engine volume, reduce the effect of output power, reach internal-combustion engine idling lotus, the light hours are saved the purpose of fuel oil.Multi-cylinder body piston type Reciprocatory internal-combustion engine just can subtract the cylinder fuel-economizing according to the automobilism situation in the application of automobile.With four cylinders combustion formula alive internal-combustion engine is example: the automobile full load, required internal-combustion engine output power is big, just carries out four cylinder workings.When automobile zero load, underloading, descending, required internal-combustion engine output power is little, with regard to available cylinder reducing oil saving method two cylinders of internal-combustion engine are not worked, the piston of non-power two cylinders is not work done of no load running under the effect of bent axle, internal-combustion engine becomes the internal-combustion engine of two cylinders like this, has also reduced simultaneously half swept volume of former internal-combustion engine, and internal-combustion engine is in idling lotus, light hours like this, because the minimizing of internal combustion engine cylinder number, swept volume, output power has also just determined the minimizing of fuel of internal combustion engine.Because internal-combustion engine four cylinders become two cylinders, and swept volume reduces half, can reach 50% so save fuel oil again, in the application of vehicle, owing to be according to vehicle-mounted load, road conditions carries out fuel-economizing, so fuel-economizing of the present invention is at 0-50%.
Multi-cylinder body idol cylinder is counted the selection that the Reciprocatory internal-combustion piston engine subtracts cylinder deactivation: we know that the work done angle between each cylinder of multi-cylinder body internal-combustion engine requires to equate that as 90 °, 120 °, 180 ° etc., this is the stable working for internal-combustion engine.In order to guarantee the stable working of internal-combustion engine, this just requires us when subtracting cylinder deactivation, makes the work done angle of the cylinder that does not stop work done keeping the same, to increase stability.
As four each cylinder work done of cylinder Reciprocatory internal-combustion piston engine is 1-2-4-3 in proper order, 180 ° at work done angle, and power distributes as figure-1, to subtract cylinder deactivation work as internal-combustion engine,, just must subtract and stop 1 cylinder according to power work done distribution map-1,4 cylinders or 2 cylinders, 3 cylinders, the work done angle of remaining like this cylinder could equate, be 360 ° and spend work done once, stop 2 cylinders, 3 cylinders to subtract, remain 1 cylinder, 4 cylinders are example: the power work done distributes as figure-2, and internal-combustion engine could reduce vibration like this, stable working, work done is even.Four-cylinder internal combustion engine becomes two-cycle engine.
Spark plug formula (gasoline, ethanol) multi-cylinder body, even cylinder are counted the method that the Reciprocatory internal-combustion piston engine subtracts the cylinder deactivation fuel-economizing and are finished by figure-3 devices of being looked.Its structure characteristic: subtracted cylinder deactivation admission passage [1], air inlet pipe [2], gasoline, the air mixing vaporizer is taken over [3], changes core [5] in the threeway throw over switch shell [4], threeway throw over switch and forms.Figure-3 is the internal-combustion engine normal working, and the gasoline mixed steam that is come out by vaporizer passes through gasoline, the air mixing vaporizer is taken over [3], changes core [5] in the threeway throw over switch shell [4], threeway throw over switch, subtracted cylinder deactivation admission passage [1], normally entered internal-combustion engine, the internal-combustion engine proper functioning.When the contained idling lotus of internal-combustion engine, the light hours, need subtract the cylinder fuel-economizing, rotation threeway throw over switch interior commentaries on classics core [5] enters figure-4 and subtracts cylinder fuel-economizing state, gasoline, air mixing vaporizer [3] changes core [5] by the threeway throw over switch, closes.Open air simultaneously and take over [2], air passes through under the effect of internal combustion engine negative pressure like this, and air is taken over [2], change core [5] in the threeway throw over switch shell [4], threeway throw over switch, subtracted cylinder deactivation suction tude [1], enter internal-combustion engine, owing to be that what to be subtracted cylinder deactivation into internal-combustion engine is air, so this cylinder spark plug ignore combustion, being subtracted cylinder deactivation can not work, because this not work done of cylinder, no load running is so played minimizing internal combustion engine volume, so that reduce gasoline, air mixing vapour enters the throttle flow of internal-combustion engine.Play the fuel oil effect of saving.
Oil sprayer self-combusting type (diesel oil etc.) Reciprocatory, multi-cylinder body idol cylinder number, the contained idling lotus of internal-combustion piston engine, light load subtract the cylinder deactivation fuel-economizing, also finish by the threeway throw over switch, different with spark ignitor type gasoline engine is that the threeway throw over switch is not mounted on the intake duct, is subtracted the cylinder deactivation injection pump assembly to the fuel feeding arm of oil sprayer and be mounted in.As figure-5, the high-pressure diesel that comes out from oil pump passes through like this, is subtracted cylinder deactivation oil pump assy fuel feeding arm [1], change core [5] in the threeway throw over switch shell [4], threeway throw over switch, subtracted cylinder deactivation fuel supply line [3], to being subtracted the cylinder deactivation oil sprayer, normal fuel injection, internal-combustion engine proper functioning.When the contained idling lotus of internal-combustion engine, light load, when this cylinder need subtract the cylinder fuel-economizing, rotating changes core [5] in the threeway throw over switch, make it this throw over switch and enter to subtract and stop the fuel-economizing state, as figure-6, high-pressure diesel passes through oil pump like this, subtracted cylinder deactivation oil pump assy fuel feeding arm [1], changeed core [5] in the threeway throw over switch shell [4], threeway throw over switch, lead to tank drainback pipe [2], got back to fuel tank again.The quilt of internal-combustion engine subtracts cylinder deactivation owing to do not obtain fuel feeding, so this cylinder can not work done, and empty moving commentaries on classics of piston.Play the effect same that subtracts the cylinder deactivation fuel-economizing with gasoline engine thus.
Originally subtract the cylinder deactivation oil saving method, it is best to be used on the Reciprocatory piston type multi-cylinder body internal-combustion engine of haulage device effect, and this is because zero load, the underloading phenomenon of automobile are very general at present, have up to 50%, this is a very big energy waste.
The present invention has been arranged, just can overcome the above problems.When automobile zero load, underloading, during descending, the available cylinder deactivation oil saving method that subtracts carries out fuel-economizing operation, can be with former internal-combustion engine proper functioning during heavy duty.
To be subtracted the cylinder deactivation number be half of former internal combustion engine cylinder number because multi-cylinder body idol cylinder is counted stroke piston combustion engine, and to making cylinder capacity also just reduce half, output power has also just reduced half, and fuel oil also just reduces half.Because automobile is in the travelling when zero load, underloading, descending, use to subtract the cylinder deactivation oil saving method again, so remaining the internal-combustion engine output power is enough to make automobile normal running.
Owing to originally subtract the cylinder deactivation oil saving method is to carry out the fuel-economizing operation according to the load variations situation of the contained equipment of internal-combustion engine, so oil-saving effect is between 0-50%.
