摘要： A diaphragm valve for a vehicle includes: a diaphragm chamber having an upper chamber and a lower chamber divided by a diaphragm and communicating with a valve inlet and a valve outlet. The upper chamber has a nipple in which a fluid flows or from which a fluid is discharged, and the lower chamber has a chamber opening port at a lower end thereof. A valve rod is coupled to the diaphragm and extends toward the valve outlet. A valve head is provided at a position corresponding to an end W of the valve rod and has a wider cross sectional area than the valve rod. The valve head closes the valve outlet when the valve is closed, and closes the chamber opening port when the valve is open.

摘要： 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.

摘要： The present disclosure provides a fuel injection unit for an internal combustion engine. The fuel injection unit includes: a separator that is disposed in an intake port to supplie air into a combustion chamber formed in an engine head, and that divides a channel for air into an upper channel and a lower channel; a blade disposed ahead of the separator and opening or closing the upper channel or the lower channel by rotating; and a first injector disposed over the intake port. In particular, when the first injector injects fuel, the blade does not interfere with the fuel.
