Title: System and method for controlling engine knock using electro-hydraulic valve actuation

Patent · Tue Dec 10 00:00:00 EST 2013

OSTI ID:1109488

Brennan, Daniel G

A control system for an engine includes a knock control module and a valve control module. The knock control module adjusts a period that one or more of an intake valve and an exhaust valve of a cylinder are open based on engine knock corresponding to the cylinder. The valve control module, based on the adjusted period, controls the one or more of the intake valve and the exhaust valve using one or more hydraulic actuators.
