Embodiment Construction

[0034] The following description is merely exemplary in nature and is not intended to limit the disclosure, application or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0035] refer to figure 1 , the engine to which the present disclosure is applied is configured such that if the air filtered through the air cleaner 1 is introduced after being regulated by the throttle valve 3, the air entering the duct 5 is supplied to the supercharging device 7 or causes the air to bypass the supercharging device. The pressure device 7 is supplied directly to the bypass pipe 11 of the intake manifold 9 .

[0036] A supercharger may be used as the supercharging device 7, and the air passing through the supercharging device 7 is supplied to the intake manifold 9 via the buffer tank 13 and the intercooler 15, and the intake manifold 9 distributes and supplies the air to the engine's correspondi...

Abstract

An engine intake bypass system includes: an intake pipe supplying air passing through a throttle valve to an intake manifold along a first path via a supercharging device, and directly supplying air passing through the throttle valve to the intake manifold after bypassing the supercharging device along a second path; a bypass pipe disposed in the second path to receive air from the inlet pipe and convey the air in parallel to the intake manifold; and a bypass valve mounted to interrupt supply of air to the bypass pipe.

Description

technical field [0001] The present disclosure relates to an intake system of an engine, and particularly relates to a technology related to an intake structure of an engine provided with a supercharging device. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] Supercharging devices for increasing the amount of air flowing into the engine include a turbocharger that compresses intake air by using the energy of exhaust gas discharged from the engine, and a turbocharger that compresses intake air by using a different power source without using exhaust gas. compressor. [0004] A turbocharger has the side effect that, due to the use of the exhaust gases, the engine back pressure increases and the amount of gas remaining in the combustion chamber increases. Therefore, turbochargers are not suitable for lean-burn or super-lean-burn gasoline engines. [0...
