    摘要: This disclosure relates a water pump, a system for cooling internal combustion engine components including a water pump, and a method for operating an internal combustion engine including a water pump. The water pump, system and method provide protection of the pump impeller during dry pump operation, such as when a watercraft engine is started while the watercraft is out of water, by dispensing fluid from a reservoir to the pump's impeller chamber. The fluid enters the chamber via a controllable flow path and interacts with the impeller and chamber walls to cool and lubricate the impeller.

    摘要: One embodiment of the present invention includes an internal combustion engine system designed to increase exhaust temperature when operating with a low mechanical load—such as idle operation. This increased exhaust temperature is provided to operate aftertreatment equipment. Exhaust temperature is raised by operating a portion of the engine pistons in a brake mode to increase loading on a remainder of the pistons operating in a combustion mode to drive the engine. Fuel provided to pistons operating in the combustion mode is regulated to maintain speed of the engine within a desired idle speed range.

    摘要: This disclosure relates a water pump control system for an internal combustion engine, and a method for operating an internal combustion engine including a clutch-controlled water pump. The water pump control system and method provide protection of the pump impeller during dry pump operation, such as when a watercraft engine is started while the watercraft is out of water, by turning off the clutch-controlled pump when no water is detected at the inlet of the water pump.
