Description
Technical field
The present invention relates to a kind of engine pre-lubrication system.
Background technique
Along with the continuous upgrading of automotive engineering, the production technology of motor is more and more accurate, and the matching gap in motor between each friction pair is also more and more less, and the matching gap maintaining between friction pair is a main prerequisite that guarantees the long-term smooth running of motor.Because good solution is not found in the wearing and tearing for engine component always, thereby stability and the reliability of motor have directly been affected.Data show, surpass motor zero wearing and tearing generation in three minutes after starting a cold engine of 90%, if can effectively resolve motor lubricating in starting a cold engine process, substantially just solved the wear problem of motor.
The lubricated of motor is mainly to be completed by mechanical oil pump, and mechanical oil pump is to be driven by engine crankshaft, must after engine start, could normally move, and causes motor in the process starting, not have lubricant oil to supply with.More seriously, motor is through parking for a long time or not using for a long time car in the situation that of (as overnight, weekend etc.), in-engine machine oil can be back in the oil sump of motor bottom, the first half of motor in inorganic oil, lack lubricated situation, ato unit under this condition, most of part is all in dry condition; In addition, the viscosity of machine oil when low temperature is relatively large, bring very large difficulty to the oil suction of mechanical engine oil pump, particularly after motor just starts, also in idle in the situation that, (now the rotating speed of mechanical engine oil pump is on the low side, oil absorption is general), approximately will be after engine start about 30 seconds, just can machine oil be transported to motor because of the running of mechanical engine oil pump and need most the parts such as lubricated piston, connecting rod and bent axle, the wearing and tearing that cause have thus caused serious impact to engine performance and life-span.
At present, the domestic and international main mode that increases an electronic oil pump that adopts in this problem that solves cold start-up wearing and tearing, before engine start with electronic oil pump by oil delivery on the main oil gallery of motor and the surface of each friction pair.But this scheme is up to the present main or take the motor of high-power as main, generally has two kinds of structures; An electronic oil pump independently, or and Starter integrated.The volume of this type of electronic oil pump can be very large, and the power of motor also can be very high, and general heavy horsepower and medium and small horsepower engine cannot meet in installing space and storage battery specification, and perfect not enough in control program and use.Up to the present domestic, on heavy horsepower and middle fraction horsepower, also do not have the electronic oil pump of appropriate size to select, the carrying capacity that adds city's field alignment heavy goods vehicles improves constantly, so medium and heavy motor can become main research and development object and developing direction, in this evolution, wearing and tearing are problems that must solve.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of can carry out prelubricated system to engine component.
The technical solution adopted in the present invention is: a kind of engine intelligent type pre-lubrication system, comprise oil sump and engine lubrication system, it is characterized in that, this engine intelligent type pre-lubrication system also comprises pre-lubrication oil pump, controller, controller supply module and for detection of the pressure transducer of the oil pressure of engine lubrication system; The entrance of described pre-lubrication oil pump is communicated with oil sump, and outlet is communicated with the lubricating oil path of engine lubrication system; The signal output part of described pressure transducer is electrically connected to the signal input part of controller, described controller starts described pre-lubrication oil pump when obtaining the power supply of described controller supply module, and quits work according to the testing result control pre-lubrication oil pump of described pressure transducer.
The invention has the beneficial effects as follows:
1. the present invention is not changing and is affecting under the oil circuit of the former lubrication system of motor and the prerequisite of function, be parallel in the lubrication system of motor, the oil leab of motor is filled up machine oil in realization before engine start, avoid the dry type wearing and tearing in engine starting process, under the prerequisite that meets motor actual conditions needs, also reduced power consumpiton;
2. controller of the present invention can, according to the working state of the oil pressure regulating working conditions system of motor reality, meeting under the prerequisite of motor actual demand, also have been avoided unnecessary energy loss;
3. the present invention's controller after pre-lubrication operation of oil pump certain hour will be cut off the electricity supply, and the time span of setting can guarantee that this system sets up required oil pressure by lubrication system, thereby prevents under abnormal conditions the complete situation of vehicle-used battery jar loss;
4. controller of the present invention can stop the operation of this system when there is situation when abnormal, has improved safety in utilization;
5. if motor is with ECU (electronic control unit) or ECM(electronic control module) unlatching that can direct control system or close, can directly utilize ECU or ECM as controller of the present invention; If Engine ECU or ECM can not control electrodynamic type oil transfer pump and open or close, a controller can be installed separately again.
