Discuss the FRACTIONATING COLUMN in Oil Refinery Plant

Name the parts of a fuel injector.

Fuel pump is a statement of the volume of the fuel flow from the pump.

technician A says that the fuel tank cap has a valve to prevent pressure build up in the tank. Technician B says that the cap has a valve to prevent vacuum build up in the tank. Who is right?

1-While refilling an 8-quart (7.57 L) system with coolant: Technician A initially puts in 4 quarts (3.78 L) of straight coolant and tops it off with water. Technician B fills the system with the correct mixture, tightens the radiator cap, and then checks for leaks. Who is correct? 2-While checking for conditions that might cause coolant electrolysis: Technician A places the positive lead of a voltmeter into the coolant and connects the negative lead to a ground. Technician B checks for the presence of voltage in the coolant with the ignition off. Who is correct? 3-Technician A says that if the PCV valve or connecting hoses become clogged, excessive pressure will develop in the crankcase and can cause oil leaks. Technician B says that if the PCV valve or connecting hoses become clogged, oil may be pushed into the air cleaner or cause it to be drawn into the intake manifold. Who is correct?  4-While bleeding air from a cooling system: Technician A loosens a heater hose at its highest…

Research for fuel supply

Which of the following statement about carbon dioxide is not true? a. CO2 , levels are highest when the air fuel ratio is slightly leaner than stoichiometric. b. The production CO2  , is directly related to the amount of fuel consumed; therfore, more fuel efficient engines produce less CO2 c. To reduce CO2 , levels in the exhaust, engineers are working hard    to decrease fuel consumption to keep CO2  low. d. The concern for CO2 emissions is on of the primary reasons for the delayed use of alternative fuels for automobiles.
