Engine can be caused many things. Depending on the exact nature of the knock, the problem can range from a simple need to higher octane fuel, to more serious problems such as engine damage. I would recommend having a professional technician, such as one from YourMechanic, inspect and listen to the vehicle noise so that a proper diagnosis and repair can be made.
