An intake valve system for an engine mounted on a vehicle and generating electric power used by the vehicle. The system includes a valve device having a valve body being moved by a stepping motor; and a controller configured to control a degree of opening of the valve device by supplying to the valve device a request indicating a specific number of steps in which the specific number of steps is a number of steps for driving the engine with a specific characteristic and the stepping motor is to operate according to the specific number of steps, and the controller is configured to control the degree of opening of the valve device by correcting a number of steps when an actual characteristic of the engine is different from the specific characteristic under a situation where the request indicating the specific number of steps is supplied to the valve device.

A battery pack for use in providing starting power for a starter motor of an internal combustion engine and to supply power to one or more auxiliary loads. The battery pack includes an outer housing that encloses a plurality of battery cells. The battery pack further includes a control module. The control module includes a processing circuit configured to control one or more functions associated with the internal combustion engine and an interface circuit configured to interface with the internal combustion engine.

A method for controlling and engine system with a plurality of turbochargers. At least one of the plurality of turbochargers has a turbine valve, a compressor valve, and actuators operable to change the position of the turbine valve. The method comprises controlling the actuator based on the presence of a transient event or a steady state event. During a transient event an engine control module can control the actuators to change the turbine valve to opened and closed positions and the turbine valve to a closed position based on the comparison between a corrected mass flow per turbocharger to a mass flow threshold.

An electronic governor system includes a motor, a transmission coupled to the motor, a throttle plate coupled to the transmission, the throttle plate movable to multiple positions between closed and wide-open, wherein power is supplied to the motor to move the throttle pate to a desired position and wherein power is not supplied to the motor to maintain the throttle plate in the desired position.

A surgical stapler including an anvil, a staple cartridge, and a buttress material removably retained to the anvil and/or staple cartridge. In various embodiments, the staple cartridge can include at least one staple removably stored therein which can, when deployed, or fired, therefrom, contact the buttress material and remove the buttress material from the anvil and/or staple cartridge. In at least one embodiment, the anvil can include at least one lip and/or groove configured to removably retain the buttress material to the anvil until deformable members extending from the surgical staple are bent by the anvil and are directed toward and contact the buttress material.

According to some embodiments, the present disclosure may relate to a system including a gaseous fuel consuming engine operating at an air to fuel ratio (AFR) and including a throttle valve controlling a speed of engine, and an engine controller coupled to the engine. The engine controller may be configured to obtain the speed of the engine and obtain the AFR of the engine. The engine controller may also be configured to, based on a transient event affecting the engine, coordinate modification of both the throttle valve to change the speed of the engine and trim valve to change the AFR of the engine to maintain at least one of the speed and the AFR of the engine within a threshold deviance.

One embodiment of the invention relates to an internal combustion engine including an engine block, a crankshaft configured to rotate about a crankshaft axis, a flywheel coupled to the crankshaft, a throttle body, an electric fan, and an air filter assembly configured to filter incoming air from an air intake and provide cleaned air to a throttle body. The engine block includes a cylinder. The throttle body is configured to throttle incoming air to the cylinder.

A surgical stapler including an anvil, a staple cartridge, and a buttress material removably retained to the anvil and/or staple cartridge. In various embodiments, the staple cartridge can include at least one staple removably stored therein which can, when deployed, or fired, therefrom, contact the buttress material and remove the buttress material from the anvil and/or staple cartridge. In at least one embodiment, the anvil can include at least one lip and/or groove configured to removably retain the buttress material to the anvil until deformable members extending from the surgical staple are bent by the anvil and are directed toward and contact the buttress material.

While providing the control such that the air excess ratio falls within the stoichiometric range, if the throttle opening degree control means determines that a value of the torque is smaller than A [Nm], the throttle opening degree control means provides a first control of controlling the opening degree of the intake throttle valve such that the output shaft rotates at a constant first rotation number. If the throttle opening degree control means determines that the value of the torque is larger than A [Nm], the throttle opening degree control means provides a second control of controlling the opening degree of the intake throttle valve such that the rotation number of the output shaft becomes larger.

According to some embodiments, the present disclosure may relate to a system including a gaseous fuel consuming engine operating at an air to fuel ratio (AFR) and including a throttle valve controlling a speed of engine, and an engine controller coupled to the engine. The engine controller may be configured to obtain the speed of the engine and obtain the AFR of the engine. The engine controller may also be configured to, based on a transient event affecting the engine, coordinate modification of both the throttle valve to change the speed of the engine and trim valve to change the AFR of the engine to maintain at least one of the speed and the AFR of the engine within a threshold deviance.
