Problems solved by technology

[0003] Due to the harsh working environment of the exhaust gas turbocharger, the intermediate shaft of the turbocharger needs to be lubricated and cooled in time, especially in the working condition of rapid shutdown after heavy load operation, and the existing exhaust gas turbocharger due to its own characteristics, at this time The lubrication and cooling system stops circulation, so that the internal heat of the supercharger cannot be dissipated, and the temperature of the intermediate shaft rises, which may easily cause oil coking, block the rotation of the intermediate shaft, and damage the supercharger; As the number of times increases, the probability of supercharger oil coking increases, making the supercharger more likely to be damaged, and eventually causing the failure of the whole vehicle

Embodiment Construction

[0033] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0034] Please refer to figure 1 , in a specific embodiment, a time-delayed water cooling device provided by the present invention includes a controller 2, a time-delay water pump 4 connected to the controller 2, and a cooling water circuit 5 for cooling the supercharger 6. The water pump 4 is connected to the cooling water circuit 5; the signal of the battery, the ignition switch and the engine are respectively connected to the controller 2; the controller 2 detects that the ignition switch is in the off state and the engine turns from the running state to the flameout state, and controls ...

Abstract

The invention belongs to the technical field of automobile components, and provides a time delay water cooling device and a control method thereof. The time delay water cooling device comprises a controller, a time delay water pump connected with the controller and a cooling water loop used to cool a supercharger, wherein the time delay water pump is connected with the cooling water loop, and a storage battery, an ignition switch and an engine are respectively connected with the controller. When the controller detects that the ignition switch is in a closing state and the engine turns into an extinction state from a running state, the controller controls the time delay water pump to start, and the time delay water pump drives the cooling water loop to circulate. According to the time delay water cooling device, the cooling water loop and the time delay water pump are added in the existing supercharger, the time delay water pump is started after the engine stops work, the cooling water loop is driven by the time delay water pump to circulate so as to reduce temperature in the supercharger as quickly as possible, engine oil is prevented from coking, the supercharger is protected, and therefore normal running of a whole car is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of automobile parts, and in particular relates to a time-delayed water cooling device and a control method thereof. Background technique [0002] In recent years, as emission and energy-saving regulations have become more stringent, engines have moved toward downsizing and more fuel-saving technologies. Exhaust gas turbocharging technology, which can use the energy of engine exhaust gas to increase engine power and torque, and start-stop technology, can effectively reduce fuel consumption in urban working conditions, and is widely used by OEMs. The existing exhaust gas turbocharger is only equipped with internal lubrication and cooling water circuits. When the exhaust gas turbocharger works, the internal lubrication and cooling water circuits are activated at the same time. When the exhaust gas turbocharger stops working, its internal Lubrication and cooling systems also stopped working. [0003] Due to th...
