摘要:
A breather device A1 for pressure relief includes a breather pipe 121 serving as a fixing part, and an inner pipe 122 serving as a communication part and is provided by the breather pipe 121 with fixation strength enough for securing the breather device A1 to a liquid tank 101. The inner pipe 122 has a vent hole P formed therein for provide fluid-communication between the inside of the liquid tank 101 and the outside thereof in a manner such that an inner surface forming the vent hole P is made of a resin.
摘要:
A closed crankcase ventilation system for an internal combustion engine is disclosed. The system comprises a flow path configured to enable crankcase emissions to flow from a crankcase of an internal combustion engine. A compressor is configured to enhance the flow of crankcase emissions from the crankcase by drawing the crankcase emissions into the compressor, to draw air from a source, and to compress the air and crankcase emissions. A treatment element is provided downstream of the compressor and configured to treat the compressed air and crankcase emissions exiting the compressor to remove entrained oil. A first conduit downstream of the treatment element is configured to introduce a first portion of the compressed air and crankcase emissions into one of an exhaust system for the engine and an air intake system for the engine. A second conduit downstream of the treatment element is configured to introduce a second portion of the air and crankcase emissions into a system having at least one component utilizing compressed air for its operation.
摘要:
A breather for a motorcycle engine separates and traps oil droplets entrained with crankcase gases. The breather has a container with a removable lid, an inlet for crankcase gases and entrained oil droplets extending through the lid into the container, filter media within the container to trap entrained oil droplets in the crankcase gases in the container, and outlet ports in the lid allowing gases to escape from within the container.
摘要:
An oil separator provided in combination with a cylinder head cover of an internal combustion engine. The oil separator includes a separator cover fixed to an inner surface of the cylinder head cover defining a space extending in a first direction perpendicular to axis of a camshaft in plan, between the separator cover and the cylinder head cover. The separator cover has an opening through which the space is opened to a valve operating chamber. A partition wall is provided to define in the space an inlet-side separator chamber and an outlet-side separator. The partition wall extends in a second direction parallel with the axis of the camshaft and being formed with a plurality of fine passages. Additionally, a plurality of projection walls project from a part of the inner surface of the cylinder head cover which faces the valve operating chamber through the opening.
