CM Advanced Ch.5 Flashcards
Basic principles of all carburetors are the same and may be found in the construction mechanic 3&2, NAVEDTRA 10644-G1, or what U.S army publication?
TM-9-8000
Compressed air used for cleaning purposes should not exceed what psi?
30
What systems are an increasingly popular alternative to the carburetor for providing an air-fuel mixture?
Fuel-injection
What is the most precise form of fuel injection and is the most complex?
Timed injection
There are two types of timed fuel injection: what are they?
Mechanical and electrical
What is a form of continuous injection-one or two injectors delivering gasoline to the engine from one central point in the intake manifold?
Throttle body injection
What is the most frequent type of servicing you will perform on a gasoline fuel injection system?
Preventive maintenance
Gasoline fuel injection systems operate with fuel pressures up to how many times greater than that of standard gasoline fuel systems?
Five(5)
Gasoline fuel injection systems have up to eight different manufacturers and over how many different models?
21
There are three types of caterpillar fuel injection systems: the forged body, the compact, and what metering systems?
Sleeve
Normal governor operation takes over at low-idle speed, approximately what rpm?
500
The most common causes of low pressure are restricted fuel supply, air leaks on the suction side of the pump, worn transfer pump blades, or a malfunctioning what?
Regulator valve
What fuel injection is used on multi-fuel engines?
American Bosch
The purpose of what is to deliver measured quantities of fuel, accurately under high pressure to the spray nozzle for injection?
Fuel pump
The American Bosch nozzle nit is how many inches long, and the nozzle has a hand-printed drilling code?
3
The Robert Bosch nozzle nut is how many inches long, and the nozzle tip has a machine-etched drilling code?
2
If you can check the condition of a nozzle before it is diassembled by using the what?
Kiene
The result of most fuel pump failures is that either no fuel or an insufficient amount of fuel is delivered to the what?
Fuel injectors
What is an emissions control device and removing it or tampering with it is in direct violation of state and federal vehicle exhaust emissions laws?
Aneroid
All pump tests should be made with the testing fuel oil temperature between 90°F and what?
100°F
The three major components of the air induction systems that increase internal combustion engine efficiency are blowers, superchargers, and what else?
Turbochargers
What are used to clear the cylinders of exhaust gases to introduce a new charge of fresh air?
Scavenging blowers
What is a gear-driven air pump that uses rotors to force air into the engine cylinders when a requirement for more power exists?
Supercharger
What unit that is driven by exhaust gas to force (charged) air into the Diesel engine cylinders for more complete burning of fuel and to increase engine power?
Turbocharger
