Abstract:
A method of controlling a choke valve of an engine with a controller is disclosed. Also disclosed is an automatic choke performing the method, an engine having the automatic choke, and an apparatus having the engine. The controller includes an electronic circuit, such as a programmable device, and is coupled to a temperature sensor and a motor. The method includes determining a temperature value using the temperature sensor, determining a time period to hold the choke valve in a first position, keeping the choke valve at the first position for the time period, moving the choke valve from the first position toward a second position using the motor, determining a count to hold the choke valve, keeping the choke valve at the second position for the count, and moving the choke valve from the second position toward a fully open position.
Abstract:
An engine including an automatic choke that includes a choke valve movable between a fully closed position and a fully open position, a temperature sensor coupled to the engine and operable to provide a temperature signal indicative of a temperature of the engine, and a motor connected to the choke valve and operable to move the choke valve in response to a motor control signal. A controller is electrically connected to the motor and to the temperature sensor. The controller includes an electronic circuit having a memory. A table includes engine specific choke position data stored in memory, wherein the controller determines a choke initial position based on the temperature of the engine and the choke position data, and wherein the motor moves the choke valve toward that position in response to an attempt to start the engine.

Abstract:
An automatic choke connectable to an engine. Also disclosed is an engine including the automatic choke, an apparatus including the engine and the automatic choke, and a method of controlling a choke valve. The automatic choke includes a motor for moving a choke valve and a controller electrically connected to the motor. In one construction, the controller is configured to store position information and a flag related to a position of the choke valve, determine the engine has, and control the automatic choke with the stored position information based on the flag and the determination that the engine has re-started. In another construction, the controller is configured to generate a motor control signal to direct the choke valve to a fully-open position without providing choke relief based on a temperature value indicating the engine temperature is greater than a threshold.

Abstract:
The conduit marking device comprises a slotted, marked measuring handle for a conduit bender. The measuring handle may be a replacement for the handle provided with the conduit bender. The measuring handle of the conduit marking device provides the ability to easily measure, mark, and align conduit in order to obtain precise results for the bends. The measuring handle is hollow and tubular and a piece of conduit may be inserted into the measuring handle from one end of the handle. The measuring handle incorporates slots, which allow the conduit to be seen through portions of the handle. Measuring indicia on the measuring handle allow specific locations on the conduit to be located and the locations may be marked through the slots on the measuring handle.
