A fuel injector for liquefied gaseous fuel includes a housing defining a fuel path from an inlet end to an outlet end. A nozzle is disposed at the outlet end of the housing. The nozzle includes an orifice for delivering liquid fuel from the fuel injector and forms a valve seat. A valve assembly is disposed in the housing and is configured to control flow of fuel through the orifice. The valve assembly includes a reciprocating valve body that is movable within the housing between a closed position and an open position. A valve seal is held by the valve body and is formed of an elastomeric material. The valve seal includes a flat sealing surface that faces the nozzle and is configured to contact the valve seat so as to inhibit flow of fuel through the orifice.

Fluid injector with flat sealing surface

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.

Fluid-cooled manifolds and engine systems

Three dimensional structural frames and enclosures and related methods are disclosed herein. In an example embodiment, an enclosure includes a plurality of three dimensional structural frames and opposing wall portions interconnected by the plurality of three dimensional structural frames, where the wall portions include a plurality of uniform wall sections, where the wall sections include a wall panel portion, a top wall portion, and sidewall portions, where the sidewall portions of the plurality of wall sections are joined to form the wall portions, and where the plurality of three dimensional structural frames are attached to the top wall portions of the wall sections.

Three dimensional structural frames and enclosures

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.

Modular power take-off assembly

Systems and methods for driving engine auxiliaries are provided. A front drive power take-off system is used to drive an auxiliary unit mounted on the engine. A pulley and belt drive assembly includes a drive sprocket mounted on the engine crankshaft, a toothed belt interconnecting the drive sprocket, and a pulley mounted on a drive shaft of the auxiliary unit to transmits power from crankshaft to the auxiliary unit.
