Description
(1) technical field:
The utility model relates to motor, specifically is a kind of efficient explosive motor.
(2) background technique:
Internal combustion engine main body is a cylinder body, and cylinder body suitable for reading by the cylinder cap capping is provided with piston in the cylinder body, to-and-fro motion between motion top dead center and the motion lower dead center of piston in cylinder body.
The to-and-fro motion of piston is divided into air inlet, compression, blast acting and four processes of exhaust:
1, air inlet (promptly air-breathing).Piston is opened suction port when top dead center moves downward, close relief opening.Piston moves downward to the process of lower dead center from top dead center, and the valve of suction port is in opening state, and the valve of relief opening is in closed condition.When piston was made charge motion, control gear control fueling injection equipment was from the oil nozzle oil spout.Oil nozzle can be arranged at directly oil spout in cylinder body on the cylinder cap, also can be arranged in the intake duct, and the mist of oil of ejection is together entered in the cylinder body with air.
2, compression.Piston is closed suction port when lower dead center moves upward.Piston moves up in the process of top dead center from lower dead center, and suction port valve and relief opening valve all are in closed condition.
3, blast acting.Piston moves up to top dead center, and the mixed combustion body is lighted in the firing chamber, and mixed combustion body moment combustion explosion promotes piston to lower dead center motion output power.
4, exhaust.Piston is opened relief opening when lower dead center moves upward.Piston moves up to top dead center from lower dead center, and this moment, the valve of suction port was in closed condition, and the valve of relief opening is in opening state, and the waste gas that mixed combustion body combustion explosion produces is discharged.
The top dead center of piston motion and the chamber between the cylinder cap are the firing chamber, and the lower dead center of piston motion and the chamber between the cylinder cap are suction chamber (comprising the firing chamber); Suction chamber is a compression ratio with the ratio of firing chamber.
Compression ratio is an important indicator of explosive motor; Compression ratio is big more, and the density of the mixed gas in the preceding firing chamber of lighting a fire is just big more, can make fuel combustion more complete on the one hand during burning; Fuel availability is higher, energy consumption is lower; Toxic emission is also lower, and the output of the power of motor is bigger on the other hand, so those skilled in the art hopes recently to improve through the compression that improves explosive motor above-mentioned each item index of motor always.But because the amalgam of air in the cylinder and atomization gas temperature in compressed process can sharply raise, therefore, if compression ratio is too high, mixed gas has reached SIT and detonation in advance before igniting, and pinking takes place, and motor is caused damage.
For addressing the above problem, existing technology mainly is through reducing the density of oil gas in the firing chamber, perhaps through reducing oil temperature supplying, reduce the temperature of firing chamber like the method with the oil plant cooling, avoiding the generation of detonation situation.Can make the compression ratio of gasoline internal combustion engine reach 9.5～10.6 now through these two kinds of methods, the compression ratio of diesel internal combustion motor reaches 18～22, if but continue to improve compression ratio, still detonation possibly take place then.
(3) model utility content:
The utility model purpose provides a kind of efficient explosive motor that improves fuel availability and raising output power through water spray.
Efficient explosive motor; Comprise cylinder body; Cylinder body suitable for reading by the cylinder cap capping, cylinder body or cylinder cap are provided with air inlet system, venting gas appliance and the fueling injection equipment with the inner chamber of cylinder block conducting, also be provided with in the cylinder body move reciprocatingly piston; And comprise that at least also one can make water fogging and atomized water is imported the water spray projector system in the cylinder body, and control water spray projector system opens and closes and regulates the control gear of injection flow rate; Said control gear control water spray projector system makes it when piston is done air-breathing motion, fueling injection equipment oil spout action finishes back ejection atomized water.
In inner chamber of cylinder block, import the effect of atomized water:
1, owing to import atomized water refrigeration is arranged, but the temperature of moment reduction inner chamber of cylinder block, thus thereby improve amount of air drawn and improve the air density in the cylinder body.The air of many inspirations can make fuel combustion more complete on the one hand, improves fuel availability, therefore can reduce fuel injection quantity, thereby cut down the consumption of energy, and reduces and pollutes; The air of many inspirations has increased the air quantity that participation is expanded and done work in the cylinder body when the blast acting on the other hand, thereby has increased the output power of motor.
2, owing to import atomized water, along with the rising of temperature in the cylinder body, the part globule begins gasification during compression, and when the blast acting, atomized water is further vaporized under high temperature action, and the volume of gasified water sharply expands, and further strengthens engine power output.
3, owing to can freeze to inner chamber of cylinder block when importing atomized water, and the gasification of the part globule also absorbs heat in the cylinder during compression, thus the speed of the rising of temperature in the cylinder body can delay to compress the time, and therefore, the internal-combustion engine of high compression ratio provides the space in order to design more.The raising of compression ratio will further improve the efficient and the output power of internal-combustion engine, also will further improve other many indexs of motor.
After mist of oil and water smoke meet, make fuel emulsification, the water spray action is preferably in to be carried out after the oil spout action is accomplished.
A kind of better simply water spray projector system is to utilize the mouth that sprays water with high pressure to make water fogging and spray, and the mouth that sprays water with high pressure is set at least, and the mouth that sprays water with high pressure can be arranged on the cylinder cap, perhaps is arranged in the air-flow path of air inlet system.The mouth that sprays water with high pressure both can make water fogging well, and the atomized water of its ejection has preferably the moment refrigeration again.
Because the recycle stream when piston is done air-breathing moving in the cylinder body can be with the water smoke band from the firing chamber; And breathing process is when finishing, and the eddy motion in the cylinder almost stops, therefore; Spray water again at the back segment of breathing process more water smoke is accumulated in the firing chamber; Make local instantaneous temperature reduction, the more air of inspiration make it to do air-breathing motion and suction stroke at 50%～100% o'clock ejection atomized water at piston like control gear control water spray projector system.As said control gear control water spray projector system make it piston do air-breathing motion and suction stroke 70%～100% in addition suction stroke better at 90%～100% o'clock ejection atomized water.
The temperature of the atomized water of the mouth that sprays water with high pressure ejection is T＞0 ℃, T≤10 ℃ better, T＞0 ℃ preferably, T≤5 ℃.
The injection flow rate of water spray projector system can be adjusted according to the engine running situation; Injection flow rate is a prerequisite can not make engine misses; Injection flow rate is directly proportional with the volume of motor generally speaking, experiment draw each injection flow rate be the injection flow rate of every liter of engine capacity be 0.2 gram～3 grams better.
