Description

Auto intercooling system with turbocharged engine

technical field

The utility model relates to the technical field of automobiles, in particular to an intercooling system of an automobile equipped with a turbocharged engine.

Background technique

With the popularity of turbocharged engines, more and more consumers find that after a certain mileage, the intercooler and the intercooler pipeline have oil leakage, or the air filter element is polluted by oil (for external pressure relief valve models).

The reason is that today's turbocharged engines are basically equipped with a closed-loop crankcase breather. The oil and gas in the crankcase will be re-sucked into the engine for combustion, and a small amount of oil and gas will enter the intercooler through the crankshaft breather and the supercharger bearing. The air pipe spreads to the entire intercooler and related pipelines, and becomes oily after being condensed by condensation. In mild cases, oil leakage occurs locally, and in severe cases, the filter element is polluted or the intercooler pipeline is blocked. According to the test experience, generally when the engine travels about 40,000 km, there will be obvious oil accumulation in the pipeline. This problem is common in autonomous and joint venture passenger cars.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

In order to prevent the oil in the turbocharged engine from accumulating in the intercooling system or diffusing to the filter element of the air filter, the intercooling system of the automobile equipped with the turbocharged engine of the present invention provides an efficient and low-cost solution.

Please refer to Fig. 1, the automotive intercooling system equipped with a turbocharged engine according to the preferred embodiment of the utility model includes an air inlet 1, an air filter 2, an intake pipe 3, a supercharger 4, and an intercooler in sequence along the direction of air flow. Intake pipe 5, intercooler 6, intercooler outlet pipe 7 and throttle valve 8, intercooler outlet pipe 7 is provided with a bypass connected to pressure relief valve 9, and the outlet of pressure relief valve 9 is connected to intake pipe 3 The pressure relief valve outlet pipe 10. The bottom of the intercooler 6 is provided with an oil drain bolt 11 for blocking the oil drain.

During the running of the engine, air is inhaled from the air inlet 1, filtered by the air filter 2, and then enters the supercharger 4 through the intake pipe 3. The temperature of the gas compressed by the supercharger 4 is very high and needs to be processed by the intercooler 6 . The specific path for the high-temperature gas to enter the intercooler 6 is as follows: intercooler intake pipe 5→intercooler 6→intercooler outlet pipe 7, and finally reaches the throttle valve 8.

For models with external pressure relief valve, when the engine is stopped, the throttle valve 8 has been closed, and part of the sluggish gas needs to be discharged into the intake pipe 3 through the pressure relief valve 9 and the pressure relief valve outlet pipe 10 at the outlet pipe 7 of the intercooler, so as to Less shock to the throttle valve 8.

In the illustrated embodiment, the intercooler 6 is at the lowest position in the entire intercooler system of a car equipped with a turbocharged engine, the air inlet 1 is located above the side of the intercooler 6, the air filter 2, the pressure relief valve 9 Located above the intercooler 6, the supercharger 4 and the throttle valve 8 are located above the rear of the intercooler 6. The intercooler intake pipe 5 is arranged at the bottom of the intercooler 6 , and the intercooler outlet pipe 7 is arranged at the top of the intercooler 6 .

When the engine is running, when the high-temperature gas passes through the intercooler 6, part of the oil vapor condenses and accumulates at the oil drain bolt 11 at the bottom of the intercooler 6. Simultaneously, in the intercooler outlet pipe 7, part of the machine oil condenses and adheres to the pipe wall, but it will slowly flow into the oil drain bolt 11 of the intercooler 6 after the vehicle stops.

When the engine stops, a small amount of oil vapor will adhere to the air outlet pipe 10 of the pressure relief valve and the air outlet pipe 7 of the intercooler along the air outlet path during the pressure relief process. A small amount of engine oil attached to the outlet pipe 10 of the pressure relief valve flows back to the oil drain bolt 11 of the intercooler 6 . And the small amount of engine oil attached to the intercooler outlet pipe 7 is far away from the air filter 2 because the interface of the pressure relief valve outlet pipe 10 and the intercooler outlet pipe 7 is far away from the air filter 2. This small amount of engine oil will not pollute the air filter 2. After the engine is started, it is sucked into the engine for combustion.

When the automobile is maintained, unscrew the oil drain bolt 11 every 20,000 kilometers, and wait for the machine oil in the intercooler to drain from the oil drain.

In summary, the vehicle intercooling system equipped with a turbocharged engine of the present invention has the following advantages:

(1) In the entire intercooling system of a car equipped with a turbocharged engine, the intercooler 6 is at the lowest position, so that the engine oil can return to the oil drain bolt 11;

(2) There is no U-shaped or V-shaped pipeline in the intercooling system of a car equipped with a turbocharged engine, so as to avoid accumulation of oil in the pipeline;

(3) For models with an external pressure relief valve, the connection point between the pressure relief valve outlet pipe 10 and the intercooler outlet pipe 7 (air intake pipe) should be lower than the air filter 2 and keep at least 200mm from the air filter 2 distance to prevent the filter element of the air filter 2 from being polluted by oil and gas;

(4) An oil drain bolt 11 is provided at the lower part of the intercooler 6 to regularly drain engine oil during maintenance, so as to avoid a large amount of engine oil accumulation caused by excessive driving mileage or time, resulting in pipeline blockage.

The intercooling system of the automobile equipped with a turbocharged engine of the utility model solves the problem of engine oil accumulation in the automobile equipped with a turbocharged engine through the cooperation of the optimization of the layout method and the optimization of the structure of the intercooler.
