Description
Technical field
The utility model relates to automotive engine applications, is specifically related to a kind of engine oilconsumption measurement mechanism, is applicable to simplify structure, reduce measuring error.
Background technology
Engine oilconsumption is one of important indicator that engine runs, and directly affects car load economy and user's use sense is subject to.At present conventional engine motor oil consumption measuring method is: on engine pedestal under regulation operating mode running engine in the stipulated time, weigh engine inner engine oil weight before and after test by method of draining the oil, the two difference is the oil consumption under this test condition.But the data error obtained by this mode is larger, main cause has two: 1, engine is drained the oil and weighed machine oil total amount, selected measurer must match with machine oil total amount, but the consumption of lubricating oil produced in testing experiment only accounts for the very little part of machine oil total amount (about 2%) usually, this just requires that measurer possesses wide range and high precision simultaneously, and generally, measurer range is larger, precision is lower, especially, when needs accurately contrast oil consumption, the deficiency of measurer precision often causes larger interference to test findings; 2, drain the oil in weighing process and there is multiple Manual operation link, and machine oil may in engine in various degree residual in surface of friction pair, oil sump, measuring tank, these all can cause larger accidental error.Along with the continuous lifting of current power machine technology, oil consumption proportion in engine motor oil total amount constantly reduces, and complete machine weight method medial error of draining the oil also just embodies more and more obvious to the interference that oil consumption is tested.
Chinese patent: application publication number is CN103674149A, Shen Qing Publication day is that the patent of invention on September 17th, 2012 discloses a kind of oil consumption real-time measurement instrument and measuring method thereof, comprise oil can, electronic scale, variable-frequency oil suction assembly, frequency conversion dump pump assembly and supervisory control comuter, oil suction pump frequency converter and dump pump frequency converter and electronic scale respectively with supervisory control comuter control linkage, the frequency controlling described oil suction pump frequency converter and dump pump frequency converter by supervisory control comuter regulates the rotating speed of described oil suction pump motor and dump pump motor, and then control the pump oil of oil suction pump and dump pump, liquid level equilibrium adjustment is carried out to oil sump, and monitor oil can figure-of-merit curve Changing Pattern in real time by supervisory control comuter and electronic scale.Although this invention can measure engine oil consumption in real time, but still there is following defect:
1, this invention utilizes frequency converter to adjust the oil mass of oil pump and dump pump to keep the oil mass in engine sump tank constant, namely adopts the mode of variable frequency adjustment, so must need a large amount of staking-out works, and not directly perceived, easily produces measuring error, not easily evaluates;
2, this invention need adopt special oil outlet pump, dump pump to control the turnover of machine oil, and presses equilibrium of forces for keeping in oil can and engine crankcase, and on oil can, need arrange separately the connecting line leading to engine crankcase, therefore its structure is comparatively complicated.
Summary of the invention
The purpose of this utility model is larger, the baroque problem of measuring error overcoming existing structure existence, provides a kind of engine oilconsumption measurement mechanism that can reduce measuring error, simplify structure.
For realizing above object, the technical solution of the utility model is as follows:
A kind of engine oilconsumption measurement mechanism, comprise engine sump tank, oil sump tank, dump pump, weighing device, described oil sump tank is arranged on weighing device;
The sidewall of described engine sump tank offers drain tap, this drain tap is positioned at the top of oil sump tank, and drain tap communicates with the oil-in of oil sump tank, the oil-out of oil sump tank communicates with the oil inlet end of dump pump, and the oil outlet end of dump pump communicates with the inside of engine body.
Described dump pump is engine oil pump, and its oil inlet end is communicated with oil-out by oil trap.
Compared with prior art, the beneficial effects of the utility model are:
1, in a kind of engine oilconsumption of the utility model measurement mechanism engine sump tank sidewall on offer drain tap, and drain tap is positioned at the top of oil sump tank, drain tap communicates with the oil-in of oil sump tank, the oil-out of oil sump tank communicates with the oil inlet end of dump pump, the oil outlet end of dump pump communicates with the inside of engine body, a dynamic closed loop system is formed by engine and oil sump tank inside, engine sump tank, the each cavity of engine interior and friction pair gap, the summation of oil sump tank and each connecting line inner engine oil is the machine oil total amount of closed-loop system, during use, under keeping the oil mass of blowback engine body to be greater than the condition of engine oilconsumption, machine oil will be continued to flow into oil sump tank by drain tap under gravity, thus make the oil level in engine sump tank keep constant, machine oil variable quantity (i.e. oil consumption) in whole closed-loop system is all converted into the oil mass change in oil sump tank, this design is without the need to adopting frequency converter, oil outlet pump, pipeline connects simple, and rely on dynamic closed loop system self can keep pressing equilibrium of forces in oil sump tank and engine crankcase, not only structure is simple, easy realization, and effectively reduce measuring error.Therefore, the utility model simplifies the structure, decreases measuring error.
2, in a kind of engine oilconsumption of the utility model measurement mechanism, dump pump is engine oil pump, its oil inlet end is communicated with oil-out by oil trap, namely utilize the lubricating oil pump of engine self that the lubricating oil pump in oil sump tank is postbacked motivation body interior, avoid and additionally increase oil pump device, can not only reduce costs, and be conducive to the Integration Design of engine.Therefore, the utility model not only reduces cost, and is conducive to the Integration Design of engine.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1 in the utility model.
Fig. 2 is the structural representation of embodiment 2 in the utility model.
