Oil burners test study with Complete Solutions What are the three major functions for a fuel unit on an oil burner? - Answer-lift the oil from the tank to the burner, deliver oil at a constant and regulated pressure to the nozzle, provides clean cutoff of fuel. What are the two major types of fuel units? - Answer-single-stage and two-stage What does the first set of gears do on a two stage fuel unit? - Answer-pull oil from the tank What does the second set of gears do on a two stage f...

Engine Performance Final The primary (low-voltage) ignition system must be working correctly before any spark occurs from a coil. Which component is NOT in the primary ignition circuit? - Spark Plug Wires An ion-sensing ignition system allow the ignition system itself to be able to ________. - detect misfire, spark knock, and rich/lean mixture How does a waste-spark ignition system fire the spark plugs? - The same plug always is fired straight or reverse polarity The pulse generat...

AMP 221 TURBINE THEORY FINAL EXAM STUDY GUIDE When an engine with a subsonic divergent type inlet duct is running in place at high speed on the ground, the air pressure within the inlet is Positive What will result if an oil filter becomes completely blocked? Oil will flow at the normal rate through the system. Why are turbine engine igniters less susceptible to fouling than reciprocating engine spark plugs? The high-intensity spark cleans the igniter. For what primary purpose is a turb...
