As shown in fig. 1, according to an embodiment of the present utility model, an engine is proposed, which includes an oil pan 10, an oil reservoir 40, a liquid level sensor 20, and a control mechanism. Wherein the oil pan 10 communicates with the main oil passage 70 of the engine, the oil reservoir 40 communicates with the oil pan 10 and the main oil passage 70, the liquid level sensor 20 is provided in the oil pan 10, and the liquid level sensor 20 functions to detect the liquid level in the oil pan 10. The control mechanism is electrically connected with the liquid level sensor 20, and the control mechanism is respectively communicated with the main oil duct 70 and the oil pan 10.

According to the engine of the present utility model, the liquid level sensor 20 is provided in the oil pan 10 for determining the level of the liquid, and the liquid level sensor 20 is electrically connected to a control mechanism that determines whether to deliver the oil of the main oil passage 70 to the oil reservoir 40 or to deliver the oil of the oil reservoir 40 to the oil pan 10 according to the level of the liquid. Therefore, the engine can control the oil quantity in the oil pan 10, ensure that the oil quantity in the oil pan 10 is maintained in a normal state, and avoid the occurrence of faults such as oil stirring of a crankshaft, high oil consumption or oil loss of the engine. Wherein, the crankshaft stirs too much oil, and the temperature is easy to rise, resulting in the deterioration of the engine oil, thereby reducing the performance of the engine oil.

It will be appreciated that the control mechanism includes an oil return solenoid valve 32, with the oil return solenoid valve 32 being disposed on a line that communicates between the reservoir 40 and the main oil gallery 70. When the oil in the oil pan 10 is too much, the oil return solenoid valve 32 is opened to deliver the oil of the main oil gallery 70 to the oil reservoir 40, so that the oil of the main oil gallery 70 is not too much, and the excessive oil can reduce the output of the engine, burn the oil, cause the piston to be blocked, the nozzle to be blocked, and easily cause the explosion of the oil reservoir 40, the oil leakage of the oil-gas separator, the stirring of the crankshaft, and the like.

Specifically, the control mechanism further includes a control unit 31, and the control unit 31 is electrically connected to the liquid level sensor 20 and the oil return solenoid valve 32. The control unit 31 determines whether the oil in the oil pan 10 is excessive or not, and whether adjustment is necessary, by reading the value of the oil level sensor 20 and comparing it with the calibrated value of the oil level.

It is to be understood that the oil reservoir 40 is disposed above the oil pan 10 in the gravitational direction. The oil reservoir 40 is disposed above the oil pan 10 in the direction of gravity, so that there is no need to separately add a pump body to convey the oil from the oil reservoir 40 to the oil pan 10, and the oil is conveyed to the oil pan 10 by gravity alone.

It will be appreciated that the control mechanism includes an oil replenishment solenoid valve 33, the oil replenishment solenoid valve 33 is provided on a line communicating between the oil reservoir 40 and the oil pan 10, and the oil replenishment solenoid valve 33 is electrically connected to the control unit 31. When the oil in the oil pan 10 is too small, the oil-supplementing electromagnetic valve 33 is opened, the oil can flow from the oil storage tank 40 to the oil pan 10 under the influence of gravity, the problem of too small oil in the oil pan 10 is solved, the lubrication effect among various parts of the engine is poor, and the phenomena of bearing bush ablation, cylinder drawing and the like are easily caused.

In some embodiments, the number of the liquid level sensors 20 is two, and the two liquid level sensors 20 are provided on the front and rear sides of the oil pan 10 in the vehicle traveling direction, respectively. The liquid level sensors 20 are disposed at both front and rear sides of the oil pan 10 in the traveling direction of the vehicle, and can accurately judge the inclination angle of the engine, thereby judging the optimal liquid level of the engine oil in the oil pan 10. In an actual application scenario, the vehicle encounters a long-section ascending or descending condition, and at this time, the dual-liquid-level sensor 20 can determine the optimal liquid level of the engine oil in the oil pan 10 according to the change of the inclination angle of the oil pan 10, so that the control mechanism starts to adjust the liquid level in the oil pan 10.

Specifically, the engine further includes a strainer 60, and the strainer 60 is provided at a central position of the oil pan 10 so that the strainer 60 can suck the oil in the oil pan 10 to the maximum degree in both an ascending and descending condition.

Specifically, the engine further includes an oil pump 50, the oil pump 50 is connected to the strainer 60, and the oil pump 50 provides a suction force for the strainer 60 to suck the oil in the oil pan 10.

Specifically, the engine further includes a filter 80 and a cooler 81, the filter 80 being connected downstream of the oil pump 50, the filter 80 being in communication with the main oil passage 70 through the cooler 81. The filter 80 can filter out impurities in the engine oil, and prevent the impurities from scratching internal parts of the engine.

Specifically, the engine also includes an air compressor 91, a supercharger 92, a valve train, a gear mechanism 93, and other mechanisms 94 requiring engine oil. The oil enters these parts of the engine that require oil through the main oil passage, and returns from these parts to the oil pan 10.

The embodiment also comprises a vehicle comprising the engine.

The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
