Question

which of the following typically happens when cranking a gasoline engine that uses a computer controlled engine management system? select one: a. engine sensors are monitored and fuel injectors are adjusted. b. ignition timing and exhaust flow are adjusted. c. the fuel pump does not pressurize the fuel system. d. the starter motor is permanently de - energized.

Explanation:

When cranking a gasoline - engine with a computer - controlled engine management system, engine sensors are monitored to gather data about engine conditions such as temperature, air - flow, etc. Based on this data, fuel injectors are adjusted to provide the correct amount of fuel for combustion. Ignition timing is adjusted during normal operation rather than just during cranking. The fuel pump pressurizes the fuel system during cranking, and the starter motor is only de - energized after the engine starts.

Answer:

A. Engine sensors are monitored and fuel injectors are adjusted.
