摘要:
A cylinder deactivation (DOD™) engine is provided with features and operated in a manner to increase the cylinder air charges of the operating cylinders in DOD operation with the DOD cylinders cut out. The increased charge air allows higher loading of the STD cylinders extending the range of torque loads and speeds for DOD engine operation without requiring switchover to STD operation wherein all cylinders are in operation. The result is increased overall efficiency by extended operation of the engine in a DOD mode wherein the operating cylinders have higher levels of volumetric efficiency and reduced fuel consumption.

A throttling and intake control system transitions between activated and deactivated modes in a displacement on demand engine. The throttling and intake control system includes an intake manifold pressure sensor that generates an intake manifold pressure signal and a controller that calculates a pressure window based on the manifold pressure and an engine speed signal. The controller transitions the engine from the activated mode to the deactivated mode when the measured intake manifold pressure is greater than the maximum limit of the pressure window. The controller transitions the engine from the deactivated mode to the activated mode when the intake manifold pressure is less than the lower limit of the pressure window.

A method of reducing exhaust emission from a catalytic converter apparatus of a vehicle, the apparatus including at least one catalytic converter, each of the at least one catalytic converter having a catalyst brick positioned within a predefined length of the vehicle. The method includes directing exhaust to pass more than once through the predefined length through at least one of the at least one catalyst brick. The converter apparatus can accelerate catalyst conversion reactions and thus accelerate converter system light-off.

An engine control system transitions between activated and deactivated modes in a vehicle equipped with a manual transmission. The engine control system includes a clutch plate position sensor and a shifter shaft position sensor in communication with a controller. The controller determines if conditions to increase or reduce the number of active cylinders based on data collected from the position sensors, engine speed, and manifold absolute pressure. Prediction of the driver's next movements is the basis of the control. The sensors provide the history, averages, acceleration data, and velocity data, which lead to the driver's intent.
摘要:
A percutaneous stented valve delivery device including an inner shaft, a sheath, and a delivery capsule. The sheath slidably receives the inner shaft. A capsule proximal zone is attached to the sheath. A capsule distal zone is configured to transition between normal and flared states. A diameter of the distal zone is greater in the flared state, and the capsule includes a shape memory component that naturally assumes the normal state. The device is operable to perform a reversible partial deployment procedure in which a portion of the prosthesis is exposed distal the capsule and allowed to radially expand. Subsequently, with distal advancement of the capsule, the distal zone transitions to the flared state and imparts a collapsing force onto the prosthesis, causing the prosthesis to radially collapse and become recaptured within the delivery capsule. The capsule can include a laser cut tube encapsulated by a polymer.

摘要:
The present invention relates to an internal combustion engine having an injector which functions as a positive displacement pump and dispenses an amount of lubricant fixed for each and every operation of the injector. The fluid dispensed could be a lubricant delivered directly to crankshaft bearings, camshaft bearings, tappets or cylinder sleeve. Alternatively the fluid could be fuel, water or urea delivered to an exhaust system upstream of a catalytic converter. The injector can have a one-way valve with a valve element having a domed or conical surface for directing fluid flow across a sharp edge which induces turbulence in the fluid flow.

The present invention relates to the field of recombinant protein production in bacterial hosts. It further relates to extraction of soluble, active recombinant protein from an insoluble fraction without the use of denaturation and without the need for a refolding step. In particular, the present invention relates to a production process for obtaining high levels a soluble recombinant Type 1 interferon protein from a bacterial host.
