Problems solved by technology
While improving the efficiency and reducing the intake air temperature, the water-cooled intercooler needs to solve the problem of condensation or even freezing at the air outlet of the water-cooling intercooler. If condensation or freezing occurs, it will affect the operation of the engine. Make the engine burn abnormally, and with the application of low-pressure EGR system, this problem will be more serious

The invention relates to the technical field of automobile engines, and discloses a supercharged engine system and a condensation control method thereof. In the supercharged engine system, a water cooling branch is connected between the water inlet end and the water outlet end of the water-cooled intercooler. The water-cooling branch road is connected with a radiator, an electronic water pump and a PTC heater, and the supercharged engine system also includes a detection device for detecting the gas temperature, humidity and pressure at the air outlet of the water-cooled intercooler. The detected gas temperature, humidity and pressure at the air outlet of the water-cooled intercooler are used to adjust the speed of the electronic water pump, the boost ratio of the PTC heater and the supercharger; the adjustment action of the condensation control method includes the adjustment of the water-cooled intercooler Temperature and adjustment of intake air volume. The beneficial effect of the invention is that it can effectively prevent the gas from condensing in the water-cooled intercooler, and reduce the impact on the performance of the engine due to the adjustment process.
Description
technical field [0001] The invention relates to the technical field of automobile engines, in particular to a supercharged engine system and a condensation control method thereof. Background technique [0002] With the popularity of turbocharged technology, the application of turbocharged engines is becoming more and more popular, and turbocharged technology has become the mainstream technology of engine development. During the development of supercharged engines, the cooling of high-temperature gas after supercharging is a problem that must be solved. [0003] The high-temperature gas after supercharging needs to be cooled by an intercooler. The current mainstream intercooler technologies include air-cooled intercooler and water-cooled intercooler; Coolers are used more and more. While improving the efficiency and reducing the intake air temperature, the water-cooled intercooler needs to solve the problem of condensation or even freezing at the air outlet of the water-coo...
