Problems solved by technology

More lubricating oil in the engine will bring resistance to the engine and sacrifice part of the power of the engine. Experiments have shown that 2% to 11% of the power of the engine is sacrificed, and more carbon deposits will be generated, increasing fuel consumption and reducing engine performance.

Embodiment 1

[0028] An automobile engine lubricating oil guarantee device, suitable for all automobile internal combustion engines, especially for TGDI (TSI) engines, such as figure 1 and figure 2 As shown, the device includes an automobile engine 1, and the engine is provided with an oil pan 101 that provides crankcase oil 102. After the engine is started, the oil pump 2 pumps the oil in the oil pan into the engine crankcase. The above structure It is the existing technical structure. In the prior art, if the engine oil in the oil pan is considered to be consumed, the oil reserve refers to the oil stored in the oil pan when the upper limit scale is usually used on the oil measuring scale (generally 0.5 to 2 liters of displacement. A car is 2 to 5 liters, a car with a displacement of 2 to 5 liters is 3 to 6 liters, a car with a displacement of 5 liters or more is 6 liters or more), and the oil requirement is also the oil required for the oil pump pressure to maintain the rated pressure T...

Embodiment 2

[0034] This embodiment is based on a solution of removing the additional pipe in Embodiment 1: an automobile engine lubricating oil guarantee device, which is suitable for all internal combustion engines of automobiles, especially for TGDI (TSI) engines, such as image 3As shown, the device includes an automobile engine 1, the engine is provided with an oil pan 101 that provides crankcase oil 102, and the engine oil reserve in the engine oil pan does not consider the engine oil consumption in an oil change cycle of the automobile to keep the engine The oil reserve of the minimum amount of oil required for lubrication, the device also includes an oil addition storage tank 3, an oil addition pump 8 and a switch 9, the oil addition storage tank communicates with the oil pan through the oil addition pump, and the car battery The power supply 10 and the power input terminal of the oil adding pump are connected together through the oil replenishment switch 9-1 in the switch, and the ...

Embodiment 3

[0039] This embodiment is a further improvement on the basis of Embodiment 2, so the content in Embodiment 2 should also be taken as a part of this embodiment. In order to realize the dynamic balance of the engine oil in the oil pan, in this embodiment: Figure 4 As shown, the device also includes an oil extraction pump 12, the oil addition storage tank is connected with the oil extraction pump, and the oil extraction pump communicates with the oil pan 101 through the oil delivery pipeline, and the oil extraction pump is used to extract the oil in the oil pan. The engine oil is extracted, and the power supply of the car battery and the power input terminal of the oil extraction pump are connected together through the oil extraction switch 9-2 in the switch. When the engine oil is activated, the oil extraction pump works.

[0040] In Embodiment 2 and 3: the switch is a button switch, and the button switch is installed in the cab of the car.

Abstract

The invention discloses a lubricating oil guarantee device of an automobile engine and a control method thereof. The lubricating oil guarantee device comprises a engine oil bottom shell stored with engine oil. Minimum engine oil amount required for lubrication of the engine is kept without considering engine oil loss within an oil change period when engine oil storage is set for the engine oil bottom shell. The device further comprises an engine oil adding storage tank. The method comprises following steps: detecting storage amount of engine oil in the oil bottom for engine oil; comparing the storage amount with setting storage amount; and adding engine oil to the engine oil bottom shell till the engine oil storage amount is above the set storage amount when the storage amount is less than the set storage amount. The lubricating oil guarantee device of the automobile engine and the control method thereof have following beneficial effects: on the condition that lubrication oil amount for normal operation of the engine is satisfied, lubrication oil is supplemented to the engine when lubrication oil of the engine is constantly consumed in order to ensure that lubrication amount of the engine is the most energy-saving state; efficiency of the engine is given into full play so that a lubrication system is more reasonable; and the engine is oil-saving and generation of carbon deposition is reduced.

Description

technical field [0001] The invention belongs to an automobile engine lubricating system, in particular to an automobile engine lubricating oil guarantee device and a control method thereof. Background technique [0002] Advanced turbocharged direct injection engines (T-GDI engines, including TSI engines) have the advantages of small size, high power, fuel economy, and lower emissions. However, compared with traditional engines, T-GDI engines (including TSI engines) The operating temperature of the lubricating oil in the lubricating system is higher, resulting in a much higher consumption of lubricating oil per 1000 kilometers than that of a traditional engine. Increase the reserve of lubricating oil in the engine oil pan in the usage specification, and the amount of lubricating oil added to the engine is 200% to 250% of the most reasonable amount, or even more; the lubricating oil gauge in the cab is also when the lubricating oil is low to normal Warn when using 1.5~1.8 tim...
