Systems and methods for controlling piston cooling nozzles using control valve actuator
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).
Adapter for roller tappet of engine and engine roller tappet assembly including same
An adapter for a roller tappet of an engine may include a body and a support. The body may be combined with a cylinder block of the engine. The body may include oil inlet connected to main gallery of the cylinder block to receive an oil from the main gallery. The support may be extended from one end of the body to support the roller tappet. The support may include a first oil passageway connected to the oil inlet. The first oil passageway is formed through the body and the support to supply the oil supplied from the oil inlet to the roller tappet. Thus, the oil may be supplied from the main gallery to the roller tappet through the oil passageway so that it may not be required to form an additional oil passageway, which may supply the oil to the roller tappet, in the cylinder block.
MODULAR CYLINDER HEAD FOR ENGINE BLOCKS
A modular cylinder head is configured for use with combustion engine block configurations each having different valvetrain oiling pathways. Thus, when used with LA-style engine blocks, oil receiving/delivery ports provided by the cylinder head are compatibly interfaced with an oil outlet port provided by the engine block, thus allowing oil to pass from the engine block into the head for delivery to a valvetrain carried thereby. Alternatively, when the head is used with Magnum-style engine blocks, the oil receiving/delivery ports of the head are not used. Rather, a pushrod and lifter having internal ports are used by the cylinder head to allow oil to pass from the engine block, through the internal ports of the lifter and pushrod, and into the valvetrain.
Method for lubricating a large slow-running two-stroke engine with SIP lubricant injector
Disclosed is lubrication for a slow-running two-stroke engine, especially marine diesel engines. The lubrication uses Swirl Injection Principle by locating the lubricant injectors closer to the TDC than of the full stroke of the piston, which is closer than in typical marine diesel engines. This can be achieved by reconstructing cylinder liners or by adding new mounting holes to the cylinder. In case that such reconstruction is not possible, an improvement of SIP principles can also be achieved by directing the spray towards the TDC or to a location on the cylinder liner closer to the TDC as compared to the location of the SIP valves, for example under an angle of more than 30 degrees or even more than 60 degrees when measured from a plane normal to the cylinder axis.
PISTON COOLING JET SYSTEM
Systems are provided for a piston cooling jet system for cooling a piston of a locomotive engine. In one example, a piston cooling jet system includes a feed body hydraulically coupled to an oil reservoir and a pair of piston cooling tubes extending radially outwards, in opposite directions, from the feed body. The tubes may have showerhead outlet features at one end for uniformly spraying oil onto inlets of a piston oil gallery housed in the piston.

This can be achieved by reconstructing cylinder liners or by adding new mounting holes to the cylinder.

Power end of a pump
A frame includes a rib. The frame also includes a crosshead tube that is integral with the rib. The frame also includes a lube rail that is integral with the rib, the crosshead tube, or both. The frame also includes a nose plate that is integral with the rib, the crosshead tube, the lube rail, or a combination thereof.
SYSTEMS AND METHODS FOR CONTROLLING PISTON COOLING NOZZLES USING CONTROL VALVE ACTUATOR
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).
Valve for adjusting a cooling fluid flow for piston cooling
A valve for adjusting a cooling fluid flow from a fluid source to a plurality of injection nozzles for cooling a plurality of pistons of an internal combustion engine is provided. The valve has a fluid duct for connecting the fluid source to the plurality of injection nozzles, and a valve element which is arranged so as to be movable, in particular displaceable, in order to change a flow cross-section of the fluid duct. The valve element can be moved into a first position, in which the flow cross-section is not influenced by the valve element.
