Abstract: A fluid-cooled manifold is configured to cool exhaust from an engine. The fluid-cooled manifold includes a plurality of exhaust runners. Each of the exhaust runners includes a runner body having an inlet end and an outlet end, an exhaust conduit extending through the runner body, and a coolant passage extending through the runner body. The fluid-cooled manifold also includes an exhaust collection manifold including a plurality of inlets. Each inlet of the exhaust collection manifold is coupled to the exhaust outlet opening of a respective one of the exhaust runners. The fluid-cooled manifold also includes a coolant feed pipe and a coolant exit pipe. The coolant feed pipe includes a plurality of outlets coupled to the coolant inlets of the exhaust runners. Likewise, the coolant exit pipe includes a plurality of inlets coupled to the coolant outlets of the exhaust runners.

Abstract: An example system includes a controller configured to: receive pressure information indicative of a pressure level of the pressurized fuel between an electro-mechanical valve and an engine; based on the pressure level being below a first threshold pressure, send a first signal to open the electro-mechanical valve; determine, based on the pressure information, that the pressure level is increasing upon sending the first signal; in response to the pressure level increasing, send a second signal to activate a pump; determine that the pressure level has increased to a second threshold pressure; and provide information indicating that the engine is ready for operation.

Abstract: A modular PTO assembly and an engine system comprising a modular PTO assembly are disclosed. The modular PTO assembly is configured to be mounted and secured to a crankcase of an engine, and includes a front cover positioned on a base plate so as to define a housing. The modular PTO assembly also comprises a power input sprocket mechanically coupled to a power output sprocket via a chain. The power input sprocket is coupled to a nose of a crankshaft and is configured to rotate at an approximately same speed as the crankshaft. The power output sprocket is configured to be coupled to a shaft of an auxiliary component and to rotate at an approximately same speed as the shaft, thereby transferring power from the engine to the auxiliary component.
