Description

Technical Field

[0001] The utility model relates to the technical field of engine testing, in particular to a tool for measuring the oil level rise of an engine. Background Art

[0002] During the compression and expansion strokes of a hybrid engine, the pressure of the mixture in the cylinder is very high, and part of the mixture will enter the crankcase through the gap between the piston, piston ring, piston ring opening and cylinder liner, and mix with the engine oil in the crankcase to form "oil mist". Usually, this part of the "oil mist" needs to be introduced into the oil-gas separation system through the channels integrated in the cylinder block, cylinder head and crankcase to separate the oil and gas from water vapor; if the separation of oil and gas from water vapor is not thorough enough, the mixture of the two will gather in places such as the cylinder head cover, forming white foam (occasionally light yellow) emulsified engine oil.

[0003] Emulsification in hybrid engines is generally related to the structure of the crankcase ventilation system, the quality of the engine oil, the climate conditions in the vehicle driving area, and the vehicle driving conditions. The occurrence of emulsification will reduce the lubrication performance of the engine oil, and then the oil level will rise, resulting in reduced fuel economy and power, reduced engine reliability and life, etc.

[0004] When testing the oil level in an outdoor environment, the traditional method is to take out the oil dipstick and then measure the oil position attached to the oil dipstick to read the oil level. This method has problems such as low reading accuracy. Therefore, some manufacturers have improved the oil dipstick or used sensors to detect the oil level, but they have complex structures and high costs, and cannot test the amount of oil emulsification. In addition, the measurement effect needs to be optimized when facing different environments. Utility Model Content

[0039] like Figure 1-2 As shown, the embodiment of the present application discloses an oil level rise measuring tool for an engine, including a measuring platform and a measuring piece 8. The measuring platform is used to fix the measuring piece 8 and the oil dipstick 9, and provide a linear measuring plane for the measuring piece 8, so that the measuring piece 8 and the oil dipstick 9 are located at the same horizontal plane, which is conducive to improving the measurement accuracy and precision. The measuring piece 8 is used to cooperate with the oil dipstick 9 to measure the amount of oil level rise and the amount of oil emulsification. The position of the oil on the oil dipstick 9 and the position value of the oil emulsification are read by the measuring piece 8, so that the amount of oil rise and the amount of emulsified oil in the engine can be known, and then a reference can be provided for oil-gas separation.

[0040] In some embodiments, Figure 1 As shown, the measuring platform includes a body 1, a first protrusion 2 and a second protrusion 3. The first protrusion 2 is fixedly arranged on the upper side of the body 1 and is used to place the measuring piece 8. The second protrusion 3 is fixedly arranged on the lower side of the body 1 and corresponds to the first protrusion 2, and is used to place the oil dipstick 9. The measuring platform can be placed horizontally or vertically, thereby providing a linear measuring plane for the measuring piece 8 and the oil dipstick 9.

[0041] In this embodiment, the length of the body 1 is 200-400 mm, preferably 300 mm; the width of the body 1 is 150-200 mm, preferably 170 mm; the height of the body 1 is 10-30 mm, preferably 20 mm. By controlling the size of the body 1, the size of the oil dipstick 9 and the measuring piece 8 can be adapted to facilitate use outdoors.

[0042] The first protrusion 2 is T-shaped, and the length of the first protrusion 2 is 80-100mm, preferably 90mm; the width of the first protrusion 2 is 60-80mm, preferably 70mm; the height of the first protrusion 2 is 4-6mm, preferably 5mm. The second protrusion 3 is rectangular, and the length of the second protrusion 3 is 90-120mm, preferably 100mm, the width of the second protrusion 3 is 70-90mm, preferably 80mm; the height of the second protrusion 3 is 4-6mm, preferably 5mm. By controlling the size of the first protrusion 2 and the second protrusion 3, it is beneficial to control the position of the measuring piece 8 and the oil dipstick 9, so as to facilitate the measurement of the oil dipstick 9 by the measuring piece 8.

[0043] In some embodiments, Figure 2 As shown, the first protrusion 2 has a first placement groove 21 at the T-shaped head, and the measuring piece 8 is placed in the first placement groove 21, thereby providing a flat placement environment for the measuring piece 8, which is conducive to the use of the measuring piece 8. The second protrusion 3 has a second placement groove 31, and the oil dipstick 9 is placed in the second placement groove 31, which provides a flat placement environment for the oil dipstick 9, so that the measuring piece 8 and the oil dipstick 9 are located in the same linear plane, which is convenient for the measuring piece 8 to measure the oil rise amount and the emulsified oil amount on the oil dipstick 9.

[0044] In this embodiment, the length dimension of the first placement groove 21 is 90 mm, the width dimension is 30 mm, and the depth dimension is 2 mm, so that the measuring piece 8 can be stably placed in the first placement groove 21. The length dimension of the second placement groove 31 is 100 mm, the width dimension is 10 mm, and the depth dimension is 2 mm; on the one hand, the oil dipstick 9 can be stably placed in the second placement groove 31, and the measuring piece 8 and the oil dipstick 9 can be located at the same horizontal plane, which is conducive to reducing the reading error.

[0045] In some embodiments, Figure 1 As shown, the body 1 is provided with a stopper 4. The stopper 4 is provided with a positioning groove 41, which corresponds to the measuring member 8. When the bottom of the measuring member 8 is located in the positioning groove 41, on the one hand, the position of the measuring member 8 can be further fixed, and on the other hand, the bottom of the oil dipstick 9 can be aligned with the measuring end of the measuring member 8, thereby reducing the error.

[0046] In this embodiment, a groove 5 is formed between the block 4 and the first protrusion 2 and the second protrusion 3. On the one hand, it can reduce the weight of the main body 1. On the other hand, at normal temperature or high temperature, oil droplets attached to the oil dipstick 9 can drip into the groove 5, which is conducive to the discharge and cleaning of the dripping oil.

[0047] In some embodiments, the body 1, the first protrusion 2, the second protrusion 3 and the stopper 4 are integrally formed, and the manufacturing of the measuring platform is simpler and more convenient by the integral forming method. In the actual manufacturing process, the first protrusion 2, the second protrusion 3 and the stopper 4 can also be processed first, and then fixed to the body 1 by welding or screwing.

[0048] In this embodiment, the body 1, the first protrusion 2, the second protrusion 3 and the stopper 4 are formed by an aluminum alloy integrated machine. By using an aluminum alloy, the weight of the measuring platform can be reduced while ensuring the structural strength of the measuring platform. In the actual manufacturing process, other metal materials such as iron and steel can also be selected. High-strength plastics such as PET, PC, PA and other plastic materials can also be selected for integrated molding. Wood can also be selected.

[0049] In some embodiments, Figure 2 As shown, the first protrusion 2 is provided with a first fixing member 6 for further fixing the measuring member 8. The second protrusion 3 is provided with a second fixing member 7 for further fixing the oil dipstick 9, so that the measurement is more accurate, and the two are kept parallel on the measuring platform, which is more convenient for reading.

[0050] In this embodiment, the first fixing member 6 includes a first bolt 61 and a first gasket 62. The first gasket 62 is sleeved on the first bolt 61, and the first protrusion 2 has a first threaded hole 22. The first bolt 61 is screwed into the first threaded hole 22 of the first protrusion 2, so that the first gasket 62 is against the measuring member 8, thereby fixing the measuring member 8 on the first protrusion 2.

[0051] In this embodiment, the second fixing member 7 includes a second bolt 71 and a second gasket 72. The second gasket 72 is sleeved on the second bolt 71, and the second protrusion 3 has a second threaded hole 32. The second bolt 71 is screwed into the second threaded hole 32 of the second protrusion 3, so that the second gasket 72 and the oil dipstick 9 are abutted, thereby the oil dipstick 9 is detachably fixed on the second protrusion 3.

[0052] In some embodiments, the first fixing member 6 and the second fixing member 7 may also be components with fixing functions such as rotating buckles and latches, and appropriate components with fixing functions may be selected according to actual needs.

[0053] In some embodiments, Figure 1 As shown, the measuring piece 8 is a vernier caliper. When the measuring piece 8 is a vernier caliper, the vernier caliper is placed in the first placement groove 21, and the vernier caliper body is fixed by the first bolt 61 and the first gasket 62. The oil dipstick 9 is placed in the second placement groove 31, and the bottom of the oil dipstick 9 is abutted against one side of the stopper 4, so that the starting section of the oil dipstick 9 corresponds to the measuring end of the vernier caliper, and because a groove 5 is formed between the stopper 4 and the first protrusion 2 and the second protrusion 3, a moving space for the vernier caliper is formed, so that the amount of oil rise attached to the oil dipstick 9 and the amount of emulsified oil can be measured and the readings can be accurate.

[0054] In some embodiments, the measuring member 8 may also be a scale, and the fixing method of the scale is the same as that of a vernier caliper. By reading the position of the oil attached to the oil dipstick 9 and the emulsified oil on the corresponding scale, the amount of oil in the engine and the amount of emulsified oil can be determined. In actual use, the measuring member 8 may also be a device with a distance measurement function such as a laser rangefinder.

[0055] In this embodiment, the measuring member 8 can measure the amount of oil rise and emulsified oil attached to the oil dipstick 9 in different environments, especially in cold environments, where the measurement effect is better.
