Abstract
A cooling nozzle assembly controlled by electricity consists of cooling oil channel set on engine , oil inlet for inputting cooling oil to said channel , at least one oil nozzle for spraying cooling oil from said channel onto engine piston and solenoid operated unit for controlling cooling oil inputted to oil inlet .
Description
Technical field
The present invention relates to the cooling unit that cooling piston is used on a kind of motor, especially a kind of assembly of cooling jet that cold oil is injected in the electronic control that cools with piston on the piston to motor.
Background technique
The cooling jet that cooling piston on the motor is used is a kind of technology of comparative maturity, and it is very general using on than higher motor in heat load.General people directly fixedly are assemblied in cooling jet on the oil duct of motor according to actual needs, and in the whole operation process of motor, cold oil all sprays cold oil by cooling jet to piston and cools off with the piston to high temperature.Because motor heat load in operation process is bigger, the temperature of piston is higher, so the dilatancy amount of piston is bigger, in order to guarantee that motor is in relative less reasonable clearance because of the piston back of expanding with the matching gap of cylinder liner when the proper functioning, therefore the matching gap of general piston and cylinder liner is relatively large when cold conditions, reserves the space that piston expands.Yet motor has particularly just started when carrying out hot car when low-load, because load is less, the expansion of piston is less, gap between piston and the cylinder liner is bigger at this moment, if at this moment still spray cold oil to piston, following harm can occur: can hinder the raising and the expansion of piston temperature this moment, makes more cold oil enter into the firing chamber, cause the loss of cold oil, reduce the quality of discharging; If piston and cylinder liner are carried out work with bigger matching gap for a long time, piston can knock cylinder liner, increases the weight of the wearing and tearing of piston and cylinder liner, increases the weight of the cavitation pitting phenomenon of cylinder liner; Simultaneously, reduce the sealing and the compression ratio of firing chamber, therefore caused the temperature of engine compresses terminal point on the low side, be unfavorable for the burning of fuel oil, increased oil consumption; But also may cause the too much not fuel oil of atomizing to flow in the crankcase along cylinder wall, cause the rotten of cold oil.
Summary of the invention
The technical problem to be solved in the present invention has provided a kind of assembly of cooling jet of electronic control, it can be according to the different situations of motor real work, selectively the piston injection cold oil to motor cools off, and carries out the harm that oil spout was brought with the piston to motor that prevents to fix.
For solving the problems of the technologies described above, technological scheme of the present invention is: the assembly of cooling jet of electronic control, comprise and be arranged on cooling oil duct on the motor, described cooling oil duct is provided with the filler opening that can import cold oil in described cooling oil duct, and at least one cooling jet that the cold oil in the described cooling oil duct can be sprayed to engine piston, described injector assembly also comprises the electromagnetic control apparatus of the described filler opening input of may command cold oil.
As a kind of optimal way, but described electromagnetic control apparatus and is arranged on the normally open solenoid valve that can work on the described cooling oil duct for to be provided with the rotating speed of observing and controlling motor or the supervisory device of cold oil temperature on motor under the control of supervisory device.
As another kind of optimal way, fixedly connected between described cooling jet and the described cooling oil duct by the FERRULETYPE hex head bolt.
Adopt the assembly of cooling jet of the electronic control of said structure, owing to be the oil inlet quantity that has adopted by the cold oil of filler opening on the electromagnetic control apparatus control cooling oil duct, make cooling jet selectively to carry out the oil spout cooling to piston according to the working order of motor, stopped that motor is too much when low-load or the hot car to spray cold oil to piston, consumption of lubricating oil and effulent have been reduced, simultaneously, can make when cold car the Spielpassung between the piston and cylinder liner more reasonable, the wearing and tearing between piston and the cylinder liner and the generation of cavitation pitting phenomenon have been reduced, and saved fuel oil, prolonged the working life of cold oil.Adopt the electronic control of normally open solenoid valve, can prevent that the solenoid valve back filler opening that lost efficacy from still closing the major accident that is caused, like this, after even solenoid valve lost efficacy, filler opening can not closed yet, and does not just cut off the cooling oil circuit when low-load, not generation that can be accidents caused.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described:
Accompanying drawing is the structural representation of the assembly of cooling jet of electronic control of the present invention.
Embodiment
With reference to accompanying drawing, of the present inventionly a kind ofly for the assembly of cooling jet of electronic control be: comprise the cooling oil duct 1 that is arranged on the motor, be provided with the filler opening 2 that in cooling oil duct 1, to import cold oil on the cooling oil duct 1, also be provided with the cooling jet 6 that at least one can spray to the cold oil in the cooling oil duct 1 engine piston on cooling oil duct 1, the number of this cooling jet 6 can be set according to the actual conditions of motor.This injector assembly also comprises the electromagnetic control apparatus of may command filler opening 2 input cold oils, but electromagnetic control apparatus can be the supervisory device of rotating speed that is provided with the observing and controlling motor on the motor or cold oil temperature and be arranged on the cooling oil duct 1 can control at supervisory device under the normally open solenoid valve of working, this supervisory device can be for being located at the instrument appliance on the motor, use this instrument appliance to carry out observing and controlling to the rotating speed or the cold oil temperature of motor timely, and send different signals according to different rotating speeds or different temperature, and normally open solenoid valve can receive these signals and carry out proper functioning according to these signals; This normally open solenoid valve is by coil case 3, and electromagnet 4 and reset spring 5 constitute, and this solenoid valve can carry out the opening and closing action to filler opening under the control of the supervisory device on the motor.In order to strengthen the precision and the sealing of installing between cooling jet 6 and the cooling oil duct 1, fixedly connected between cooling jet 6 and the cooling oil duct 1 by FERRULETYPE hex head bolt 7.
The present invention is when proper functioning, and by the signal of the supervisory device on the reception of the solenoid valve in the electric controller motor, whether the filler opening of control cold oil is opened or closed.When the temperature that general rotating speed when motor is lower than a setting value or cold oil is lower than a setting value, supervisory device sends signal, coil case 3 energising effects on the solenoid valve, electromagnet 4 moves, filler opening 2 is closed, it is interior (during design to make cold oil not enter into cooling oil duct 1 by filler opening 2, if piston and cylinder liner matching gap are big, then can close filler opening 2 fully this moment, if and piston and cylinder liner matching gap are little, at this moment, then can allow a spot of cold oil to enter in the cooling oil duct 1, with to piston and cylinder liner lubricate) by filler opening 2.When the temperature that is higher than a setting value or cold oil when the rotating speed of motor is higher than a setting value, supervisory device sends signal, coil case 3 outages on the solenoid valve, electromagnet 4 moves under the effect of reset spring 5, filler opening 2 is opened, cold oil is entered in the cooling oil duct 1 by filler opening 2, spray to piston by cooling jet 6 and cool off.
