摘要:
A method of operating an internal combustion engine includes operating the engine in a first combustion mode. The method also includes switching operation of the engine to a second combustion mode. The method includes directing an exhaust stream of the engine into contact with a NOx adsorber substantially only during the operation in the second combustion mode.
摘要:
An internal combustion engine has an engine block defining at least one cylinder, a head, a piston, an air intake valve, and a valve actuator. The valve actuator has an actuator housing defining a tank and a bore, and a piston adapted to engages the air intake valve. The valve actuator further has a control valve disposed between the tank and the bore in the actuator housing. The control valve selectively moves between a first position where fluid is allowed to flow between the tank and the bore and a second position where the fluid is prevented from flowing to trap fluid in the bore, thereby preventing the engine valve from returning to a closed position. The internal combustion engine also has at least one turbocharger fluidly connected to the air intake port, and a fuel supply system operable to controllably inject fuel into the combustion chamber.

An engine and method of operating an internal combustion engine is provided. The method comprises supplying pressurized air from an intake manifold to an air intake port of a combustion chamber in the cylinder, operating an air intake valve to open the air intake port to allow the pressurized air to flow between the combustion chamber and the intake manifold during a portion of a compression stroke of the piston, and filtering particulate matter from an exhaust stream of the engine with a particulate filter.

A split inner ring of a bearing assembly comprises first and second rings, a plurality of holes, a circumferential annulus and a lubrication system. The first and second rings are configured to mate axially at inside side surfaces to define an inner raceway formed on an outer surface of the rings. The plurality of holes are circumferentially spaced and extend from an outside side surface to an inside side surface of the first ring. The circumferential annulus is formed on the inside side surface of the first ring, between the inner raceway and an inner surface of the first ring, and intersects the plurality of holes. The lubrication system connects the circumferential annulus to the outer surface of the first ring and the second ring. The lubrication system comprises circumferentially spaced slots in the first ring, or axial holes fluidly coupled with radial holes in the second ring.

A method of mixed mode operation of an internal combustion engine includes the steps of controlling a homogeneous charge combustion event timing in a given engine cycle, and controlling a conventional charge injection event to be at least a predetermined time after the homogeneous charge combustion event. An internal combustion engine is provided, including an electronic controller having a computer readable medium with a combustion timing control algorithm recorded thereon, the control algorithm including means for controlling a homogeneous charge combustion event timing and means for controlling a conventional injection event timing to be at least a predetermined time from the homogeneous charge combustion event.
摘要:
The present invention comprises an impermeable coating on an organic substrate resulting in a material that is inert, environmentally safe, impermeable and fully compostable and biodegradable. The present invention, therefore, is ideally suited to meet the ever-growing demand for compostable containers, as used in the food, beverage, agricultural, consumer products, medical, and waste industries, for example, including vacuum packaging and anti-static packaging. A possible substrate, such as a cellulose or polyactide (PLA) film and a possible coating, such as a ceramic coating of SiO2 (silicon di-oxide), are derived from organic substances and, thus, both completely degrade under natural conditions. Moreover, this biodegradation can occur under compost conditions as defined in numerous international standards, including at least ASTM D 6400.
