Embodiment 1

[0024] The invention provides a turbocharger forced lubrication cooling protection device, such as figure 1 , including a supercharger 1, and an input pipeline 11 and an output pipeline 12 respectively connected to the input end and the output end of the supercharger 1, and the input pipeline 11 and the output pipeline 12 are respectively connected to the engine coolant main pipeline 2. An electronic pump 3 is arranged on the input pipeline 11, and the electronic pump 3 is set to be normally open. The electronic pump 3 can also be arranged on the supercharger output pipeline 12, such as image 3 shown. The turbocharger forced lubrication protection device is independent from the main lubrication system of the engine, and the design of the electronic pump 3 is added. The electronic pump 3 is normally open, that is, when the engine is running, the electronic pump 3 is always running, and the electronic pump 3 can be arranged in the input pipe. Road 11 is oil or water for lubri...

Embodiment 2

[0026] On the basis of Example 1, such as figure 1 and figure 2 , also includes an engine controller ECU5 and a temperature sensor 13, the temperature sensor 13 is arranged on the bearing of the supercharger 1, and the engine controller ECU5 is electrically connected with the electronic pump 3 and the temperature sensor 13 respectively.

[0027] When the engine controller ECU5 received the starting signal of the engine 4, the engine controller ECU5 controlled the electronic pump 3 to start running to shorten the fuel supply delay time of the supercharger 1; when the engine 4 was running normally, the electronic pump 3 was in a normally open state, Engine calibration determines the rotational speed; when the engine 4 is stopped, the electronic pump 3 continues to run for a period of time, such as 30s, thereby reducing the temperature of the exhaust system and bearing temperature, so as to protect the supercharger 1 . By adding the supercharger bearing temperature sensor 13, a...

Embodiment 3

[0029] On the basis of the above examples, if Figure 4 and figure 2 , the electronic pump 3 is an electronic oil pump 32, and the input pipeline 11 and the output pipeline 12 are respectively connected to the outlet and the inlet of the engine oil pan 22.

[0030] In the present embodiment, the control steps of engine controller ECU5 are as follows:

[0031] S1: The engine controller ECU5 receives the start signal of the engine 4 .

[0032] S2: The engine controller ECU5 outputs a command, and the electronic oil pump 32 starts to rotate at a rated speed of 1500 rpm.

[0033] S3: The engine controller ECU5 receives the signal from the temperature sensor 13, and outputs instructions to the electronic oil pump 32 according to the temperature data. When the temperature is lower than 180°C, the speed of the electronic oil pump 3 is maintained at 1500 rpm; when the temperature is 180°C-210°C When the temperature is higher, the rotation speed of the electronic oil pump 3 is chan...

Abstract

The invention provides a turbosuperchager forced lubrication and cooling protection device. The device comprises a turbosuperchager, an input pipeline and an output pipeline, wherein the input pipeline and the output pipeline are connected with the input end and the output end of the turbosuperchager correspondingly. The device is characterized in that the input pipeline and the output pipeline are connected with an engine cooling liquid main pipeline, and an electric pump is arranged in one of the input pipeline and the output pipeline and is arranged to be normally opened. According to the device, the problems that due to frequent start and stop of the engine, user misoperation and hybrid power special application, dry grinding, high-temperature coking of a superchager rotor system are brought are solved, and meanwhile the problem that due to the engine arrangement factor, the superchager oil inlet pipeline is designed to be too long, and consequently the oil supply lag time is too long is also solved.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a forced lubrication and cooling protection device for a turbocharger. Background technique [0002] Superchargers have been widely used in engines because of their effectiveness in increasing engine power, reducing fuel consumption, and improving emissions. Since the turbocharger is connected to the exhaust pipe during operation, and the speed of the turbocharger is as high as hundreds of thousands of revolutions per minute during normal operation, it is necessary to ensure that the rotating shaft and bearing of the turbocharger are well lubricated, and at the same time A large amount of heat inside the supercharger is taken away from the supercharger through the flow of lubricating oil, thus playing a protective role. [0003] For the supercharger, the traditional lubrication and cooling method is to provide a certain amount of oil and oil pressure through the oil ...
