Abstract
A vehicle engine with integrated intake valve and fuel injector is provided. An intake valve is housed in an intake valve body which is provided with a valve seat face. A fuel passage is positioned at the valve seat face toward a spark plug. Further, a valve stem is disposed at the intake valve at a position above the valve seat. The valve stem can be in fluid communication with an intake valve guide and a high pressure tube. With the integrated intake valve and fuel injector, e.g., high level of charge homogeneity can be achieved in a simple manner.
