Supercharger engine and inter-cooling system

Abstract

The invention provides an inter-cooling system of a supercharger engine. The supercharger engine comprises an engine and a supercharger. The inter-cooling system comprises an intercooler, an inter-cooling air inlet pipe, an inter-cooling air outlet pipe and an unloading valve, wherein the intercooler comprises an air inlet and an air outlet; the air inlet of the intercooler is connected with the air outlet of the supercharger through the inter-cooling air inlet pipe; the air outlet of the intercooler is connected with the air inlet of the engine through the inter-cooling air outlet pipe; and the unloading valve is arranged in the inter-cooling air inlet pipe and / or the inter-cooling air outlet pipe or the inter-cooling air outlet pipe, such that air pressures in the inter-cooling air inlet pipe and / or the inter-cooling air outlet pipe are kept in a set value. The invention also provides the supercharger engine.

Description

technical field [0001] The invention relates to an engine, in particular to a supercharged engine. Background technique [0002] The most effective measure to increase engine power is to increase the air charge and fuel supply. In the related art, the turbine driven by the exhaust gas of the engine is usually used to drive the compressor to increase the intake pressure and increase the charge volume. This method is called exhaust gas turbocharging. Exhaust gas turbocharging technology can not only increase the power of diesel engines by 30% to 100% or more, but also play an important role in saving energy, preventing air pollution and reducing noise. [0003] One of the main indicators of a turbocharger is boost pressure. However, since the air temperature rises after being compressed, the air density will not increase proportionally with the boost pressure, so the engine with a high-charge turbocharger should adopt an intercooling system (hereinafter referred to as the i...

AI Technical Summary

Problems solved by technology

However, since the air temperature rises after being compressed, the air density will not increase proportionally with the boost pressure, so the engine with a high-charge turbocharger should adopt an intercooling system (hereinafter referred to as the intercooling system) to reduce the pressure. The air temperature at the outlet of the air machine increases the density of the air

The intercooling system usually includes the connection of the air pipeline. If the pressure of the air discharged from the turbocharger is too high, it will easily cause the air pipeline to fall off. Once the air pipeline falls off, the intake pressure of the engine will drop sharply, and the power of the engine will drop. Soon, it is easy to cause a very adverse impact on vehicles such as vehicles using the turbine engine
