Abstract: An engine control system is structured for operating a turbocharged engine system and includes an electronic control unit. The electronic control unit is structured to switch the engine system from operation in a parasitically loaded mode where fuel pressurized by a fuel pump is dumped to a low pressure space, to operation in a second mode, where an engine load increase is detected. Turbocharger lag in the engine system is limited during increasing the engine load by way of exhaust energy produced in response to the parasitic loading. Related methodology is disclosed.

Abstract: A cryogenic pump includes a pressurization assembly configured to be submerged in a cryogenic liquid; a hydraulic actuation assembly; and a transmission assembly in communication between the pressurization assembly and the hydraulic actuation assembly. The transmission assembly including a conduit having a first end adjacent the hydraulic actuation assembly and a second end adjacent the pressurization assembly. The conduit is configured to contain a material having a first state at the first end and a different second state at the second end.
