Abstract: A seal configuration for a fuel injector is disclosed. The seal configuration may include a seal ring within a seal groove of the fuel injector. The seal ring may be formed from a first material. The seal configuration may include a spacer ring within the seal groove of the fuel injector. The spacer ring may be formed from a second material. An outer diameter of the spacer ring may be greater than a diameter of a fuel injector bore of the fuel injector. The spacer ring may be configured to be adjacent the seal ring within the seal groove to form a seal of a fuel injector slot of an engine head of an engine, and the fuel injector slot is configured to support the fuel injector.

Abstract: A control system for a dual fuel engine having a liquid fuel supply and a gaseous fuel supply is disclosed. The control system may include at least one sensor operably coupled to a cylinder of the dual fuel engine and configured to monitor cylinder condition and transmit a cylinder condition signal. Additionally, a controller may be communicably coupled with the at least one sensor and the controller may be configured to receive the cylinder condition signal and determine whether the cylinder is operating in an abnormal operating condition. Whereas the controller determines the cylinder is operating in the abnormal operating condition, the controller sends a control signal for the liquid fuel supply to provide an amount of liquid fuel which is greater than an amount of liquid fuel supplied to the cylinder during a normal operating condition.
