Technical field
The utility model relates to a kind of motor car engine auxiliary working apparatus, and more particularly, it relates to a kind of electric-controlled type piston cooling device.
Background technique
Engine lubrication system plays a part as motor each system oil device provides lubrication and protection, and piston cooling nozzle is then taken on for piston provides lubricant oil cool, the important task that guarantee piston normally runs.Piston cooling nozzle of the prior art is usually placed on cylinder body main oil gallery, lubricate with crankshaft main journal and share main oil gallery, the opening and closing that its structure adopts steel ball to add the ball valve switch mechanism of spring or plunger to add the plunger switch mechanism controls piston cooling nozzle of spring usually.When the oil pressure in main oil gallery reaches piston cooling nozzle cracking pressure, ball valve mechanism or plunger mechanism are opened, and lubricant oil is sprayed from main oil gallery by piston cooling nozzle, cooling piston.Because cracking pressure is definite value, therefore can not control according to the cooling requirement of piston reality, inevitably cause the waste of oil pressure oil mass.Excessive oil pressure makes ball valve or plunger mechanism parts bear larger impact and stress, wearing and tearing are caused to be accelerated, and along with the wearing and tearing of ball valve or plunger mechanism, the unlatching of piston cooling nozzle, closing pressure there will be wide fluctuations, bring piston to cool the not enough risk causing damage.Publication number is that the patent of invention of CN101886570A discloses a kind of piston cooling spray nozzle structure being applied to explosive motor field on November 17th, 2011, described piston cooling spray nozzle structure comprises nozzle arrangements body, nozzle arrangements body is arranged the cavity of one end sealing, the cavity the other end arranges the opening end that diameter is less than cavity, elastic element and sealed steel ball are installed in cavity, sealed steel ball and opening end are fitted, cavity is communicated with jet nozzle flow guide pipe by valve seat, opening end on nozzle arrangements housing and set temperature sensing element and the expansion structure with function of expanding with heat and contract with cold that is connected with temperature-sensing element (device) between sealed steel ball.The cooling nozzle structure of this invention, by temperature-sensing element (device) induction oil temperature, automatically adjusts to the unlatching of piston cooling nozzle, closedown and fuel injection quantity, thus saves oil flow rate.But as previously mentioned, this invention also uses ball valve switch mechanism, there is the waste of oil pressure oil mass, closing pressure fluctuates large shortcoming.
Model utility content
Many employing ball valve switch mechanisms or plunger switch mechanism controls piston cooling nozzle in existing piston cooling device, oil pressure oil mass is easily caused to waste, cause switch member greatly stressed, accelerated wear test, and then it is large to cause closing pressure to fluctuate, for overcoming these defects, the utility model provides one can Precise Control of Oil pressure, guarantee that closing pressure is steady, extend the electric-controlled type piston cooling device in piston cooling device working life.
The technical solution of the utility model is: a kind of electric-controlled type piston cooling device, be located in car engine lubrication system, comprise crankcase oil duct, remove oil cylinder head way, connect oil duct, full controllable electromagnetic valve, the secondary oil duct of cylinder body, cylinder body main oil gallery, crankshaft lubrication oil duct, piston cooling nozzle oil duct and piston cooling nozzle, connect oil duct to be communicated with crankcase oil duct, go oil cylinder head way and cylinder body main oil gallery all be connected oil duct and be communicated with, full controllable electromagnetic valve is connected to and connects between oil duct and the secondary oil duct of cylinder body, piston cooling nozzle oil duct is located on the secondary oil duct of cylinder body, piston cooling nozzle is located on piston cooling nozzle oil duct, full controllable electromagnetic valve is electrically connected with the ECU of motor.A lubricant oil part from oil sump enters cylinder body main oil gallery by crankcase oil duct, by crankshaft lubrication oil duct lubrication crankshaft main bearing, another part then enters connection oil duct, and when full controllable electromagnetic valve is closed, the lubricant oil in connection oil duct is all by going oil cylinder head way to be transported to cylinder cap.The utility model is that piston cooling nozzle arranges the secondary oil duct of special cylinder body, when the too high needs of piston temperature cool, instruction from Engine ECU controls full controllable electromagnetic threshold switch in real time, the lubricant oil connected in oil duct passes through solenoid valve filler opening, solenoid valve oil outlet enters the secondary oil duct of cylinder body, for piston cooling nozzle provides lubricant oil.Demarcate according to different operating modes and ECU, full controllable electromagnetic valve can be regulated arbitrarily by the control of dutycycle between standard-sized sheet and full cut-off, thus regulates the oil pressure in the secondary oil duct of cylinder body in real time, for piston provides appropriate cooling in real time.
As preferably, piston cooling nozzle comprises matrix, seal ring, mounting bracket and nozzle, and mounting bracket and nozzle are connected on matrix, and intrinsic silicon is provided with piston cooling nozzle oil pocket, and seal ring is socketed on matrix.Because oil mass and oil pressure are controlled by the full controllable electromagnetic valve in front position, this piston cooling nozzle eliminates ball valve switch mechanism or plunger switch mechanism, and structure is more simple, more easy care.
As preferably, matrix, mounting bracket and nozzle are formed in one structure.Piston cooling nozzle small volume, more easily processes by one-body molded mode, more easily ensures structural strength.
The beneficial effects of the utility model are:
Improve the Economy of piston cooling device work.When the utility model runs according to motor by full controllable electromagnetic valve, the cooling requirement of each operating mode lower piston reality provides appropriate lubricant oil to carry out piston cooling, accurately controls the oil pressure by piston cooling nozzle simultaneously, reduces unnecessary redundancy waste.
Extend piston cooling device operating life.The full controllable electromagnetic valve of the utility model instead of ball valve switch mechanism or plunger switch mechanism, there is not ball valve switch mechanism under excessive oil pressure or plunger switch mechanism problem easy to wear, thus has longer working life.
