Angular2 - Insert an active instance of AppComponent into a child component

My child components of the application must access the active instance of AppComponent for various reasons, so I tried below to get a link to the AppComponent in ChildComponents, but it does not insert the active instance of AppComponent, but receives a new instance of AppComponent in all of my child components. So how to solve this problem.
