Abstract
A control system (10) used for an engine (14) having at least one cylinder (18) is provided for a piston cooling nozzle (PCN (12)). Included in the control system (10) are a main liquid rifle (20) configured to deliver a liquid to the at least one cylinder (18) of the engine (14), and a PCN liquid rifle (22) disposed inside the main liquid rifle (20) for directing the liquid from the main liquid rifle (20) to the PCN (12). The control system (10) causes the liquid to be jetted into the at least one cylinder (18) of the engine (14) for lowering a temperature of the engine (14).
Claims20
A control system (10) used for an engine (14) having at least one cylinder (18), comprising:
- a piston cooling nozzle (PCN (12));
- a main liquid rifle (20) configured to deliver a liquid to the at least one cylinder (18) of the engine (14);
- and
- a PCN liquid rifle (22) disposed inside the main liquid rifle (20) for directing the liquid from the main liquid rifle (20) to the PCN (12), causing the liquid delivered to the at least one cylinder (18) of the engine (14) to lower a temperature of the engine (14).
A control method for a piston cooling nozzle (PCN (12)) used in an engine (14) having at least one cylinder (18), comprising:
- delivering a liquid to the at least one cylinder (18) of the engine (14) via a main liquid rifle (20);
- disposing a PCN liquid rifle (22) inside the main liquid rifle (20);
- and
- directing the liquid from the main liquid rifle (20) to the PCN (12) via the PCN liquid rifle (22), thereby causing the liquid to be jetted into the at least one cylinder (18) of the engine (14) for lowering a temperature of the engine (14).
