Cut-away drawing of steam engine speed governor. The valve starts fully open at zero speed, but as the balls rotate and rise, the central valve stem is forced downward and closes the valve. The drive shaft whose speed is being sensed is top right Porter governor on a Corliss steam engine. The devices shown are on steam engines.
A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine.. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow ...
Operation in a single engine reciprocating aircraft is as follows: Engine oil is pumped through the propeller shaft by the governor to push on a piston that drives the mechanism to change pitch. The flow of oil and the pitch are controlled by a governor, consisting of a gear type pump speeder spring, flyweights, and a pilot valve. The gear type ...
A carburetor (also spelled carburettor or carburetter) [1] [2] [3] is a device used by a gasoline internal combustion engine to control and mix air and fuel entering the engine. [4] Carburetors can be quite complex but the three primary methods of adding fuel to the intake air in the main metering circuit is through the pressure difference ...
Adjustments in power output for a particular primer mover and generator combination are made by slowly raising the droop curve by increasing the spring pressure on a centrifugal governor or by an engine control unit adjustment, or the analogous operation for an electronic speed governor. All units to be connected to a grid should have the same ...
The overspeed governor is implemented on most marine diesel engines. [4] The governor is a safety measure that acts when the engine is approaching overspeed and will trip the engine off if the regulator governor fails. [4] It trips off the engine by cutting off fuel injection by having the centrifugal force act on levers linked to the governor ...
The engine can be mounted in the nose, tail, wing or mounted internally on the airframe. The engine can be mounted vertically as well as horizontally. [16] PD style carburetors are for inline and radial engines from 900 to 1900 cubic inches. [16] PT style carburetors are usually found on 1700 to 2600 cubic inch engines [16]
In 2007, the company's former gasoline engine and power train product lines, which is what the company had been most known for, were sold to Platinum Equity LLC, which does business as Tecumseh Power. Tecumseh engine products at one time were sold in over 120 countries. In December 2008, the company closed its engine manufacturing division. [12]
