Patent number: 10018105Abstract: The present disclosure provides an engine structure for a vehicle. The engine structure includes: an intake port, a port plate provided in the single flow path of the intake port, and an injector. The port plate is longitudinally parallel to the flow path of the intake port so as to divide the flow path of the intake port into upper and lower flow paths, and the port plate includes an extension portion formed on part of a downstream end of the port plate such that the extension portion of the downstream end of the port plate extends longer than other portion of the downstream end of the port plate. In particular, the injector is provided in the intake port, and sprays fuel beyond the extension portion so as to inhibit the fuel from adhering to the port plate.Type: GrantFiled: July 25, 2016Date of Patent: July 10, 2018Assignees: HYUNDAI MOTOR COMPANY, KIA MOTORS CORPORATIONInventors: Dong Ho Chu, Nahm Roh Joo, Yang Geol Lee, Jong Il Park, Yong Hoon Kim, Myung Gu Ha, Dong Hee Han
