Valve cover 1.__-an assembly holding rotating blades inside a motor housing or casing that cools the motor by pulling air in through the shroud. 2.__-a device that supplies alternating current. 3.__a machine component that rotates, slides, or oscillates. Bearings reduce friction between the motor's rotating and stationary parts. 4.__-driven shaft fitted with rotating wheels of irregular shape (cams) that open and close valves in an engine. 5.__-the ratio of the volume of the cylinder at the start of a compression stroke compared to the smaller (compressed) volume of the cylinder at the end of the stroke. 6.__-a component that connects a piston to a crankshaft. 7.__a fluid that circulates around or through an engine to remove the heat of combustion. The fluid can be a liquid (e.g., water or antifreeze) or a gas (e.g., air or freon). 8.___ a component that converts the piston's up-and-down or forward-and-backward motion into rotational motion. 9.__magnetism produced by an electric current. 10.__a machine that converts chemical (fuel) energy into mechanical force' 11.__the casing of an engine that houses the pistons and cylinders. 12.__-a chamber or cavity in an engine that collects exhaust gases and directs them out of the engine. 13.__-a valve in the head at the end of each cylinder. It opens and directs the exhaust from the cylinder to the exhaust port. 14.__a structure that holds the internal components of a motor and motor mounts. 15.__a component of an engine on the top of the piston cylinders that contains the intake and exhaust valves. 16.__ motor a motor that turns more slowly than the supplied frequency and can vary in speed based on the amount of load. 17.__an air channel that directs fuel to an intake valve. Intake valve-a valve located in the head, at the top of each cylinder, that opens, allowing air-fuel mixture to enter the cylinder. 18.__the amount of torque necessary for a motor to overcome the resistance of the driven machine. 19__a mechanical driver that converts electrical energy into useful mechanical work and provides power for rotating equipment; sometimes called a driver. 20.__a component that serves as a reservoir for the oil used to lubricate internal combustion engine parts,p.191. 21.__-a component that moves up and down or backward and forward inside a cylinder. 22.__-a flat steel ring or sleeve coated with soft metal and placed between the connecting rod and the crankshaft. 23.__-the rotating member of a motor that is connected to the shaft. 24.__a metal rod on which the rotor resides; suspended on each end by bearings, it connects the driver to the shaft of the driven end or mechanical device. 25.__a casing over the motor that allows air to flow into and around the motor. 26.__component in an internal combustion engine that supplies the spark to ignite the air-fuel mixture. 27.__-a stationary part of the motor where the alternating current supplied to the motor flows, creating a magnetic field using magnets and coiled wire. 28.__-a motor that runs at a fixed speed synchronized with the supply of electricity. 29.__-a force that produces rotation. 30.__A motor that can be driven by either AC or DC power 31.__cover over the cylinder head that keeps the valves and camshaft clean and free of dust or debris; it also keeps lubricating oil contained. 32. Areas where motors are used can be classified as possibly hazardous and include restrictions. Where can a list of restrictions be found? a. National Electric Code information b. Employee handbook c. Motor control center d. All of the above 33. What three things must process technicians do as they perform routine tasks on electric motors? a. Anticipate, explore, and think b. Look, listen, and check c. Prevent, understand, and consider d. Question, answer, and know 34. In the process industries, engines can also be called. 35. What component of internal combustion engines converts the piston's up-and-down or forward-and-backward motion into rotational motion? a. Head b. Crankshaft c. Connecting rod d. Engine block 36. List three causes of high temperatures in motors. 37. (True or False) Using the wrong lubricant can result in serious and costly equipment damage and, in some cases, catastrophic failure,fire, explosion, and injury to personnel. 38. List three key process variables that should be moni- tored during normal operation of engines. PreviousNext
