After the second exhaust poppet valve 9 is opened and hot high-pressure burned gas starts to flow away, the first exhaust poppet valve 10 is opened. As a result, the temperature of the first exhaust poppet valve 10 is reduced and the compression ratio can be increased. Then, a work amount of the piston is increased. The increased work amount compensates an amount of cooling loss due to increasing a surface area of the combustion chamber.

Variable Geometry Cam Shafts For Multiple-Cylinder Internal Combustion Engines

Номер: US20120312263A1
Автор: Francisco A. Arrieta
Принадлежит: Individual

A method of conserving fuel in the operation of multi-cylinder internal combustion engines. The present method described here allows a portion of the cylinders of an internal combustion engine to be de-activated when less power is required, thus allowing the engine to provide full power when required, or less power with substantial fuel savings. The present method does so by altering the normal operation of intake and exhaust valves by leaving the intake valve at least partially closed, and the exhaust valve at least partially open. The present method overcomes numerous problems in the prior art, such as excess load placed on the engine caused by trapped gases, damaging thermal gradients across the engine block, and difficulty of retrofitting existing engines.

Принадлежит: Individual

An eccentricity tolerant valve stem seal assembly includes an elastomeric seal having an upper metal retainer extending down and within an upper seal portion which has an inwardly directed sealing lip for contacting a valve stem. There are also a flexible middle and a lower seal portions. The lower seal portion is connected to a lower metal seal retainer that is disposed up to a lower edge of the middle seal portion. The flexible middle seal portion allows the upper seal portion to flex from an eccentric valve stem without losing the sealing function of the sealing lip. In cooperation with the above described structure, a separate cover may be in a tight tolerance fit with the lower seal retainer over top of the eccentricity tolerant valve stem seal, in order to limit axial displacement of the upper portion of the seal due to high manifold pressure.

COMBINED OIL FILTER AND RESTRICTOR ASSEMBLY

Номер: US20170002703A1
Автор: Haigh Matt, Khadilkar Prasad Shrikant, Oates James Martin
Принадлежит:

A combined oil filter and restrictor assembly is disclosed having an oil flow restrictor interposed between first and second filters so that, irrespective of the direction of oil flow through the restrictor, debris cannot enter a small diameter bore in a body of the restrictor thereby reducing the likelihood of restrictor blockage. The combined oil filter and restrictor assembly includes a metal threaded member that enables the combined oil filter and restrictor assembly to be easily and quickly assembled to or removed from a component such as a cylinder head of a variable displacement engine. The combined oil filter and restrictor assembly can be used to provide a restricted flow of oil from oil supply passages to signal oil passages used for controlling the operation of deactivatable hydraulic lash adjusters so as to purge the signal oil passages when the deactivatable hydraulic lash adjusters are not deactivated. 1. A combined oil filter and restrictor assembly comprising a filter and restrictor unit and a metal threaded member for sealingly retaining the filter and restrictor unit in position , wherein the filter and restrictor unit comprises a tubular body having a cylindrical side wall defining at least one primary oil access port located in the cylindrical side wall at a position spaced away from a first end of the tubular body , an oil flow restrictor located in the primary bore , a first filter located between a first end of the oil flow restrictor and the at least one primary oil access port and a second filter located between a second oil access port and a second end of the flow restrictor such that the oil flow restrictor is interposed between the first and second oil filters.2. The combined oil filter and restrictor assembly as claimed in claim 1 , wherein the oil flow restrictor comprises a restrictor body defining a small diameter bore and the restrictor body is located in a primary bore defined by the cylindrical wall of the tubular body.3.
