Title:
AIR INTAKE DUCT AND COMBUSTION SYSTEM OF TURBOCHARGED GASOLINE ENGINE
Document Type and Number:
WIPO Patent Application WO/2017/190593
Kind Code:
A1
Abstract:
An air intake duct comprises an air intake duct body (11). The air intake duct body (11) comprises an air intake part (111) and a connecting part (112) connected with the air intake part (111). A first channel is arranged inside the air intake part (111); a second channel is arranged inside the connecting part (112); the first channel and the second channel are intercommunicated with each other. One side of the connecting part (112) is provided with a connecting surface (112a) which inclines towards the axis of the air intake duct body (11), the connecting surface (112a) inclining and extending from a joint of the connecting part (112) and the air intake part (111) to the end of the connecting part (112) to make the area of the cross section of the first channel greater than that of the second channel. According to the air intake duct and the combustion system of a turbocharged gasoline engine provided by the invention, the connecting surface (112a) axially inclines towards the center axis of the air intake duct body (111), so that a extrusion effect on airflow is achieved to forcibly change the flow direction of the airflow. Hence, a high tumble ratio of air flow at the connecting surface (112a) of the connecting part (112) is achieved, and the combustion efficiency of the engine thus can be improved. Since no component needs to be additionally arranged on the air intake duct or a cylinder cover, the structure is simplified, and the manufacturing cost is greatly reduced.
