Thank you Nissan for the Aisin truck transmissions, the Cummins built diesel engines, and the collection of 4-cylinder engines. These components will get great use in our engines and auto trans courses for years to come! Every student in our AUT 150: Engine Fundamentals course gets to rebuild one of these modern gasoline direct injection (GDI) engines that have advanced variable valve train technology using oil controlled and electric motor-controlled cam phasers. Very cool!
