Embodiment Construction
[0024] Such as figure 1 As shown, the present invention communicates with a transparent hose 20 at the bottom of the engine oil pan 10 to form a connector, and the transparent hose is marked with a scale. The driver uses the oil dipstick 30 inserted in the oil pan 10 to measure the amount of oil in the oil pan 10. The upper limit position and the lower limit position are engraved on the oil dipstick 30. Only when the oil level in the oil pan 10 The condition for safe driving is met only when the oil dipstick 30 is located between the upper limit position and the lower limit position.
[0025] The upper limit position of the oil dipstick 30 is exactly when the oil quantity in the oil pan 10 is the maximum oil filling quantity V of the engine. max , the height at which the engine oil gauge 30 is submerged in engine oil in the oil pan 10 . The lower limit position of the oil dipstick 30 is exactly when the oil quantity in the oil pan 10 is the minimum oil filling quantity V of ...

The invention provides a confirming method for decreased amount of engine oil in oil pan during operation of an engine. The confirming method includes: connecting the oil pan with a graduated transparent tube to form a communicator, and pouring a certain amount of the engine oil into the oil pan to enable a liquid level in the transparent tube to reach a certain height; recording decreased height of the liquid level in the transparent tube after the engine works for a while, and computing the left engine oil amount in the oil pan when the engine works; using the poured engine oil amount in the oil pan to subtract the left engine oil amount in the oil pan when the engine works so as to confirm the decreased amount DeltaV of the engine oil in the oil pan. The invention further provides a confirming method for minimal engine oil amount VK in the oil pan, wherein VK=V0+DeltaV, and the V0 refers to an engine oil volume when the height of an oil level of the engine oil is positioned at a discharging line of an engine oil strainer. By confirming the above parameters, safety of a driver can be guaranteed, and cost of consumed engine oil amount can be lowered.
Description
technical field [0001] The invention relates to the technical field of engines, in particular to a method for determining the reduced amount of engine oil in an oil pan and the minimum amount of oil in the oil pan when the engine is running. Background technique [0002] At present, the independent design and development of domestic passenger car gasoline engines is still in its infancy, and the design verification methods for some key design parameters of engines are still relatively lacking. In engine design, the design of the oil pan can directly affect the performance of the engine body and the driving performance of the vehicle on which it is mounted. The most critical thing in the design of the oil pan is the oil storage capacity of the oil pan. [0003] When designing and verifying the oil storage capacity of the oil pan, it is necessary to determine the internal oil storage capacity of the engine, the reduced oil volume in the oil pan when the engine is running, and...
