A device integrating engine oil sampling and oil temperature measurement

Abstract

The invention discloses an apparatus of integrating engine machine oil sampling and machine oil temperature measuring, which comprises a temperature sensor, an oil drain bolt, a seal plug, a first Teflon tube and a second Teflon tube, wherein a rapid joint is connected between the first Teflon tube and the second Teflon tube; a back end of the second Teflon tube is connected to the oil drain bolt; the temperature sensor is located in a through hole of the temperature sensor; a temperature detection end of the temperature sensor penetrates through from a center hole of the oil drain bolt; the other end of the temperature sensor is located at an end port position at the front end of the first Teflon tube; and the seal plug is in interference relationship with the end port position at the front end of first Teflon tube. According to the invention, based on the fact that the machine oil is normally assembled and used, the inserted depth of the temperature detection portion of the temperature sensor is conveniently regulated; the measurement error is reduced; the apparatus provided herein also has the machine oil sampling function; and the operation is simple, convenient and safe.

Description

technical field [0001] The invention relates to a device integrating engine oil sampling and engine oil temperature measurement. Background technique [0002] In the engine test, the engine oil temperature is an important parameter to monitor the working state of the engine. At present, the commonly used method for measuring the oil temperature is to wrap the temperature sensor on the oil dipstick, and extend the engine oil dipstick conduit into the oil pan to measure the temperature of the oil in the oil pan. This method has the following disadvantages: 1. It affects the use and assessment of the oil gauge; 2. The oil temperature data is easy to fluctuate; 3. The inlet of the oil gauge conduit is not well sealed and oil leakage is likely to occur. In addition, it is often necessary to sample engine oil during engine tests. The common method is to remove the oil drain bolt to drain the oil for sampling. Since the temperature of the oil is high during sampling, the operator ...

Problems solved by technology

This method has the following disadvantages: 1. It affects the use and assessment of the oil gauge; 2. The oil temperature data is easy to fluctuate; 3. The inlet of the oil gauge conduit is not well sealed and oil leakage is likely to occur

The utility model integrates the temperature sensor and the oil drain bolt, and measures the temperature of the engine oil through the temperature sensor, but the temperature distribution of the engine oil in the oil pan is uneven, and the position of the temperature measuring part of the sensor in the utility model is fixed, so it is inconvenient to adjust the insertion depth, resulting in Large measurement error

Moreover, this utility model patent cannot solve the cumbersome work of oil sampling and safety issues
