A spool valve for controlling the flow of a fluid into a reciprocating piston cylinder. A spool is slideably inserted into an outer casing, the spool valve having a first and a second non-waisted end portions and having a waisted middle portion. The casing has an intake port and output port for fluids entering and exiting the casing. A first non-waisted end portion covers the intake port during a first valve-closed event as the spool slides in one direction within the casing. The waisted middle portion is sufficiently wide to uncover both the intake port and the output port during a valve-open event as the spool slides in one direction within the casing. A second non-waisted end portion covers the output port during a second valve-closed event as the spool slides in the same one direction within the casing.

Fast acting shuttle spool valve

A far square or diamond architecture engine with tumble flow to support spark-ignited fuel usage. The engine may be provided in a configuration generally suited for swirl flow, compression combustion fuel usage. However, the introduction of a unique, replaceable valve head assembly may be utilized to induce tumble flow within a combustion chamber of the engine. Thus, spark-ignited fuel may be utilized without requiring vast overhaul of the engine to accommodate such fuels. Notably, with the addition of such an assembly, diesel fuel may be replaced with natural gas on large scale equipment without the requirement of impractically burdensome or expensive measures.

Parallel intake valve tumble flow engine

A valve system that includes a housing defining an intake port, a cylinder port and a valve bore; wherein the intake port defining a valve seat portion at an interface between the intake port and the cylinder port. The valve system also includes a valve to control fluid communication between the intake port and the cylinder port. The valve includes a valve stem disposed within the valve bore and extending into the cylinder port and extending out of the housing, the valve stem having an open face exposed to atmospheric pressure and a valve head coupled to the valve stem comprising a first face and an opposing second face. A diameter of the valve stem is selected to control a closing force on the first face of the valve head.

Intake valve systems

A hydraulic lash assembly (HLA) for use in a valvetrain. The HLA preferably includes a first arm configured to transition a valve between a closed orientation and an open orientation. The first arm can include an engagement surface to receive a driving force from a timing member and to cause the valve to transition to the open orientation for a predetermined period. The HLA further preferably includes a second arm to receive a holding force from an actuator and a pivot section to couple to the first arm and displace the first arm based on the holding force from the actuator. Preferably, the first arm and the second arm form a lever arrangement whereby the pivot section of the second arm underlies and supports the first arm and allows for rotational movement of the first arm that is independent from the second arm.

Hydraulic lash assembly and valvetrain implementing same

A reciprocating piston engine, comprising an engine block having a piston cylinder; a piston disposed in the piston cylinder; an intake port to the piston cylinder, an intake valve to open and close the intake port to the piston cylinder; a rotatable crankshaft; a flywheel connected to the crankshaft which is rotatable with the crankshaft, the flywheel having a circumferential profile; and a cam lobe forming a portion of the circumferential profile of the flywheel wherein, during rotation of the crankshaft, the cam lobe acts on the intake valve to open the intake valve.

Integrated flywheel and intake cam lobe

An injector nozzle having a first part having a stem and a flange, the flange having a flange surface, a body including a wall defining a hole, an annular nozzle ring having a first surface and a second surface wherein the first surface and/or the flange surface include a plurality of grooves, the stem being received in the hole, the first part being secured to the body to secure the nozzle ring in place such that the first surface engages the flange surface, the second surface engages the body, and the plurality of grooves define a plurality of injector holes.

Injector apparatus

A testing rig and method of testing a bearing with the rig, wherein the rig includes a bearing housing, wherein said bearing housing includes an opening and a drive shaft extending into said opening, wherein the drive shaft is rotatable around a bearing axis. The testing rig also includes a vertical actuator mounted on the bearing housing for applying a vertical load to the bearing housing and a horizontal actuator mounted on the bearing housing for applying a horizontal load to the bearing housing. In addition, the testing rig includes a first misalignment actuator coupled to the first actuator for applying a first misalignment load to the bearing housing and a second misalignment actuator coupled to the bearing housing for applying a second misalignment load to the bearing housing.

Two-directional radial load and misalignment testing device

The present invention generally relates to providing an air supply for components associated with an engine. More particularly, the present invention relates to a system and method for using compressed air generated by a split-cycle engine to power components such as valves or air springs associated with the split-cycle engine.

Air supply for components of a split-cycle engine

The present invention provides a valve actuation system comprising a valve train for actuating a valve, the valve train including actuating elements and a valve lash, and a valve lash adjustment system for adjusting the valve lash, wherein the valve train and the valve lash adjustment system do not share any common actuating elements.
