Operating an engine includes opening and closing exhaust valves in an engine braking timing pattern, charging a first cylinder with air fed directly from an intake manifold, and releasing the directly fed air in a first braking event. Operating the engine further includes charging the first cylinder with air fed via a flow-through path through a second cylinder operating as an air conduit, and releasing the air fed through the flow-through path and pressurized to brake the engine in a second braking event. Related apparatus and valve lift profiles are also disclosed.

Engine braking strategy using cylinder flow-through path for optimizing braking power

A controller may identify an indication to initiate an engine braking procedure associated with an engine of a machine. The controller may obtain, based on identifying the indication to initiate the engine braking procedure, information relating to a requested amount of engine braking power of the engine. The controller may cause one or more components of a variable geometry turbocharger (VGT) of the engine to adjust, and a throttle valve of the engine to adjust, based on the information relating to the requested amount of engine braking power of the engine.

Increasing braking power and exhaust gas temperature

A modular, retrofittable, and portable drain water recycle system, for installation into, and removal from, an existing host plumbing system having a host water supply, a sink, a tub or shower, a toilet, and a sewer. The modules include a drain fixture module, a system control module, and a storage tank module, all interconnectable. Gray water is collected from a tub, shower, or sink, by a drain fixture module, and is stored in a storage tank module for reuse in flushing a toilet. The drain fixture module and storage tank module are controlled by the system control module. Capacity can be altered by adding or removing storage tank modules. Different host systems can be accommodated by adding or removing drain fixture modules and system control modules. Drain fixture modules replace or are installed nearby existing P-traps, normally accessible. Storage tank modules and system control modules are of such shape and size as to fit under a typical sink inside the sink cabinet.
