Abstract

The utility model relates to a motorcycle crank-box exhaust-gas recirculation condensed-water collector; the collector has a section of an exhaust emission pipe introduced from the vent of the crank-box, a section of exhaust emission pipe is introduced from the section between an air filter and a carburetor, the lower opening of above two pipes are connected closely with the upper part of a bottle-shape condensate collecting cup, the height of the collecting cup is lower than the vent of the crank-box. The device adopts a very simple method to solve not only the problem of premature emulsification transformation of oil in the crank-box under low temperature, but also recovers and utilizes the exhaust gas from the crank-box; the device is environmental protection and economizing on energy, also maintains the oil quality, ensures the lubricating effect for long period, prolongs the service life of the engine greatly. The device has low cost, low price, convenient operation, no fault except natural aging or being destroyed from outside force, which is applicable for existing four-stroke motorcycle of China and foreign countries style, and has quite high spreading application value.

Description

Motorcycle crankcase exhaust gas recirculation condensate collector

Affiliated technical field

The utility model relates to a kind of condensate collector, especially motorcycle crankcase exhaust gas recirculation condensate collector.

Background technique

In the past, the 4 stroke motorcycle crankcase breather directly communicated with atmosphere, caused pollution of atmosphere, waste of fuel, and airborne dust and dirt also can enter crankcase, pollutes abrasive parts using; At present, adopt the mode of waste gas circulation, it is connected the air-strainer of breathing pipe with the engine charge end more; Though this Placement has been avoided above-mentioned drawback, but produced new problem, be the higher crankcase waste gas of temperature, during through breathing pipe, can on the lower tube wall of temperature, form condensed water, and condensed water can prolong breathing pipe and flows backwards and to enter crankcase, cause lubricating oil emulsion rotten, lose lubrication, cause parts to wear and tear too early, engine noise increases, and the life-span of critical components such as camshaft just can shorten greatly; Temperature is low more, and condensation is serious more, even frequently more change engine oil is also of no avail, many users and producer all advise connecting tube is pulled up emptying, the mode of the straight-through atmosphere pollution before returning, and this real genus is helpless.To this, also there is not good solution at present.

Summary of the invention

Be connected existing shortcoming in order to overcome present crankcase waste gas pipe with the air-strainer of engine charge end, the utility model provides motorcycle crankcase exhaust gas recirculation condensate collector, this trap adopts extremely simple way, not only solved under low temperature environment, the problem of the too early emulsion deterioration of crankcase machine oil, and the waste gas that crankcase is discharged obtains good recycling use, it is environmental protection and energy saving both, the quality that can keep machine oil again, but the effect that the assurance of long period is lubricated can prolong life-span of motor greatly; This trap cost is low, price is honest and clean, convenient and practical, effect is splendid, except that natural aging or external force factor, its device proper can not break down, its utmost point is adapted to existing China and foreign countries brand 4 stroke motorcycles and uses, it has quite high application value.

The technological scheme that its technical problem that solves the utility model adopts is; This trap comprises that exhaust emission tube (3), waste gas enter pipe (4) and condensation water collection cup (8) three parts; It is characterized in that: this trap leads to one section improved exhaust pipe (3) from crankcase (1) relief opening, between air-strainer (6) and Carburetor (5), lead to one section waste gas and enter pipe (4), the opening end of this two pipes bottom, tightly connect with the top of ampuliform condensation water collection cup (8) respectively, the height of its condensation water collection cup (8), the relief opening that should be lower than crankcase (1) is installed; Like this, when crankcase scavenged waste gas, when exhaust pipe (3) after the lower improvement of excess temperature and waste gas entered pipe (4), the condensed water of formation promptly can not blow back in the crankcase.

Its beneficial effect is: this trap adopts extremely simple way, not only solved under the environment of low temperature, the problem of the too early emulsion deterioration of crankcase machine oil, and the waste gas that crankcase is discharged obtains good recycling use, it is environmental protection and energy saving both, the quality that can keep machine oil again, but the lubricated effect of the assurance of long period can prolong life-span of motor greatly; This trap cost is low, price is honest and clean, convenient and practical, remove natural aging or external force factor and destroy, its device proper can not break down, it is adapted to existing China and foreign countries brand 4 stroke motorcycle and uses, it has quite high application value.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and the embodiments;

Accompanying drawing 1 is a structural principle schematic representation of the present utility model;

Accompanying drawing 2 is a kind of structural principle schematic representation of evolution of the present utility model;

Among the figure, 1 crankcase, 2 existing flue gas leadings, 3 improved exhaust pipes, 3 ' drip pipe, 4 improved waste gas enter pipe, 4 ' toxic emission Circulation pipe, 5 Carburetors, 6 air-strainer, 7 motors, 8 condensation water collection cups.

Embodiment

In Fig. 2, this condensate collector also can develop: from crankcase (1) relief opening to Carburetor (5) and between the toxic emission Circulation pipe (4 ') of drawing between the air-strainer (6), connect one section downward condensation water collection pipe (3 '), this condensation water collection pipe (3 ') is tightly connected with condensation water collection cup (8) lower end.

In Fig. 1,2, condensation water collection cup (8) can be made transparent, so that observe water set solid water, the bottom of this glass has discharging valve, can discharge water easily, also can make the lower end closed formula, only need when discharging water that condensation water collection pipe (3 ') is separated the back draining with condensation water collection cup (8) and get final product.

In Fig. 2, during installation, the height of toxic emission Circulation pipe (4 ') and condensation water collection pipe (3 ') intersection must be lower than the exhaust entrance of crankcase (1), otherwise condensed water will reflux and enter crankcase, makes this failure of apparatus.
