Abstract
The utility model discloses a blow-by gas measuring device for a crankcase of an engine, comprising a gas-oil separator, a first decompression cabinet and a second decompression cabinet. The gas-oil separator, the first decompression cabinet and the second decompression cabinet are sequentially connected via pipelines. Blow-by gas out of the crankcase of the engine firstly enters into the gas-oil separator to separate oil from gas, and then passes through the first decompression cabinet to enter a flow gauge, and thereby blow-by gas quantity of the crankcase can be accurately measured. Gas out of the flow gauge then passes through the second decompression cabinet to be connected with an air filter. The utility model is capable of accurately measuring the blow-by gas quantity of the crankcase of the engine, and is simple in structure. Through accurate grasp of blow-by gas quantity, the utility model can evaluate the working condition of engines, which is of much importance for further design and improvement of engines.
Description
Technical field
The utility model relates to a kind of gas flow proving installation, specifically refers to crankshaft box of motorcycle engine air leak amount proving installation.
Background technology
Engine in the course of the work, the waste gas that combustion mixture in the firing chamber or burning back produce might under high pressure enter crankcase by the sealing surface between piston ring and cylinder body.Excessive in order to prevent crankcase pressure, on crankcase, be provided with the pressure release off-gas line.If the waste gas that off-gas line comes out directly enters atmosphere and will pollute environment, so off-gas line is connected with air cleaner usually, waste gas introduced the firing chamber carry out secondary combustion.The engine crankcase air leak amount is an important parameter of engine evaluated duty, and is significant for the design and the test evaluation of engine.But, also there is not a kind of device to test accurately at present to the engine crankcase air leak amount, influenced further research to the engine crankcase air leak amount.
The utility model content
At the prior art above shortcomings, the purpose of this utility model provides a kind of device that the engine crankcase air leak amount is tested.
The technical solution of the utility model is achieved in that engine crankcase air leak amount proving installation, it comprises oil-gas separator, first decompression cabinet, flowmeter and second decompression cabinet, and oil-gas separator, first decompression cabinet, flowmeter and second decompression cabinet are connected by pipeline successively.
The waste gas that comes out from the engine crankcase waste gas pipe at first enters oil-gas separator and carries out gas-oil separation (can guarantee test accuracy like this), enters flowmeter by first decompression cabinet again and just can accurately test out crankcase gas leakage.The gas that comes out from flowmeter is connected with air cleaner by second decompression cabinet again, waste gas is introduced the firing chamber carry out secondary combustion.
The utility model can directly be tested the engine crankcase air leak amount, simple in structure, test is accurate, by the accurate assurance to air leak amount, can analyze, the duty of engine evaluated, this is for the further design of engine and improve significant.
Description of drawings
Fig. 1-the utility model structural representation (in the frame of broken lines is this proving installation).
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, from the figure as can be seen, the utility model comprises oil-gas separator 1, first decompression cabinet 2, flowmeter 3 and second decompression cabinet 4, oil-gas separator 1, first decompression cabinet 2, flowmeter 3 and second decompression cabinet 4 are connected by pipeline 5 successively, oil-gas separator 1 front end is connected with the engine crankcase waste gas pipe, second decompression cabinet, 4 rear ends are connected with air cleaner 6 by pipeline, and number in the figure 7 is an engine.
The utility model principle of work is: the engine crankcase gas blowby enters oil-gas separator 1 through pipeline, and is in oil-gas separator 1 that the machine oil in the gas blowby is separated from the gas, and avoiding machine oil to enter flowmeter influences measuring accuracy.Enter first decompression cabinet 2 through pipeline 5 again through the gas of oil-gas separator 1, in first decompression cabinet 2, with in the crankcase because the positive/negative pressure that piston motion produced carries out depletion handles, guarantee to enter flowmeter gas flow rate, flow to and stablize.Gas through reduced pressure treatment enters flowmeter 3, can read flow value at this, and the gas of process flowmeter 3 enters second decompression cabinet 4 again.Because the crankcase gas blowby connects gas handling system, second decompression cabinet 4 can to air intake duct (system) carry out the depletion processing because of the operating mode stroke changes the pressure surge that produces, guarantee that pressure and direction are certain, guarantee measuring accuracy.If the directly logical atmosphere of the crankcase gas blowby of engine itself, second decompression cabinet only is equivalent to passage this moment, and is inoperative.Tap into the situation of gas system shown in the figure for the crankcase gas blowby.
