Abstract

The utility model is provided with an oil/gas separation device which is characterized in that: the device includes an enclosed oil tank, a floating chamber, a float, an exhaust valve core, an exhaust valve seat and an exhaust cap, wherein an oil inlet A connecting the oil outlet of a fuel consume sensor, an oil outlet B providing oil for the motor and an oil return mouth C connecting the oil return of the motor are arranged on the side wall of the oil tank; the float is installed in the floating chamber which is close to the top of the oil tank and fixed in the oil tank; the exhaust valve is installed in the floating chamber whose top pierces the floating chamber, the oil tank in turn and is fixed and connected with the exhaust cap; the exhaust holes are arranged on the side wall of the exhaust cap; the exhaust valve core is arranged in the middle of the lower end of the exhaust seat and over the float; a horizontal exhaust passage is arranged below the exhaust valve core adjacent to the block-up position of the exhaust valve core and the valve body longitudinal airway. The utility model can automatically separate and eliminate the gas produced in the oil circuit during the oil consumption measurement for the car without changing the oil supply status of the original car and thoroughly solves the difficult problem of non-exact measurement of the oil consumption of car.

Description

Gas and oil separating plant

Affiliated technical field

The utility model relates to the gas and oil separating plant that a kind of automobile fuel consumption detects usefulness.

Background technology

The fuel consumption of automobile is to weigh the important economic index of automotive performance, so must be accurate to the measurement result of automobile fuel consumption.At present, all adopt the low pressure recycle fuel system as the Diesel engine of automobile power or the petrolic fuel oil supply system of EFI or elementary fuel feeding, through a large amount of evidences, generation gas influences certainty of measurement in the oil circuit owing to reasons such as engine operating temperature and oil return make when carrying out automobile engine oil consumption measurement, and also can cause engine misses when gas build is serious, this shows that the accumulation of gas in the oil circuit also can influence the duty of engine, the vehicle fuel consume amount result who measures in this case is incorrect, this not only counts the gas in the oil circuit as fuel oil, also influenced the power output of tested engine.

The utility model content

The gas that the purpose of this utility model provides and a kind ofly can address the above problem, produce in oil circuit when automobile fuel consumption is measured separates eliminating automatically, guarantees automobile fuel consumption certainty of measurement gas and oil separating plant accurately.Its technology contents is:

A kind of gas and oil separating plant, it is characterized in that: comprise closed oil tank, float chamber, float, exhaust plug, delivery valve seat and exhaust cap, wherein the sidewall of fuel tank is provided with the oil-in A that connects the fuel consume sensor oil-out, give the oil-out B of engine oil and the oil return opening C of sending and receiving motivation oil return, float is installed in the float chamber, float chamber is pressed close to the fuel tank top and is fixed in the fuel tank, delivery valve seat is installed in the float chamber, float chamber is passed on its top successively, fuel tank, fixedly connected with exhaust cap, the sidewall of exhaust cap is provided with steam vent, exhaust plug is arranged on the centre of delivery valve seat lower end, and be positioned at the top of float, the below of the vertical exhaust duct block-up position of delivery valve seat adjacent row gas valve core and valve body is provided with horizontal exhaust passage.

Described gas and oil separating plant leaves the gap between the top of delivery valve seat and the top of exhaust cap, and steam vent is arranged on the exhaust cap sidewall all around of gap.

Its operation principle is: when engine operation, the fuel oil that measured through fuel consume sensor enters fuel tank from oil-in A, along with floating and head on exhaust plug, the rising float of pasta in the fuel tank seals vertical exhaust duct, the interior fuel head of fuel tank this moment remains unchanged, engine oil is supplied with from oil-out B, the oil return of engine was measured through fuel consume sensor, so can not back-steam car fuel tank, C enters closed oil tank from oil return opening, gas in the oil circuit produces from the engine oil return, float can fall to opening air bleeding valve gas is discharged when gas enters fuel tank, by float air bleeding valve is controlled at critical condition, thereby it is constant making the amount of fuel in the fuel tank, the oil mass that enters from oil-in A is exactly the amount of fuel of engine actual consumption, the fuel oil that provides to engine from oil-out B is not contain gas, so do not influence the duty of engine.

The gas that the utility model produces in oil circuit when automobile fuel consumption is measured separates eliminating automatically, this device connected with fuel consume sensor to use to measure Diesel engine and the petrolic fuel consumption of EFI accurately, and do not change the fuel feeding state of former car, thoroughly solved automobile fuel consumption and measured an inaccurate difficult problem.
