EFI Systems test

What is one of the disadvantages of fixed jet carburetors compared to Electronic Fuel Injection (EFI) systems?

• Fixed jet carburetors use fuel more efficiently

• Fixed jet carburetors make turn key operation

• Fixed jet carburetors have lower overall emissions

• Fixed jet carburetors don't have the ability to deal with all changing operating parameters running engines encounter

Which of the following is an advantage of using EFI in modern outboards?

• Higher overall emissions

• Less efficient use of fuel

• Ability to deal with changing operating parameters

• Reliance on motor's throttle valve opening

What does EFI stand for?

• Electronic Fuel Injection

• Efficient Fuel Intake

• Engine Fuel Indicator

• Electronic Filter Integration

What type of device is a fuel injector?

• Hydraulic device

• Electro-magnetic fueling device

• Mechanical lever

• Manual pump

What controls the operation of a fuel injector?

• The vehicle's battery

• The electronic control module (ECM)

• The fuel pump

• The engine's pistons

What happens when the injector's electrical circuit is completed (turned ON)?

• The injector is deactivated

• The fuel is blocked from passing through the injector

• Pressurized fuel is allowed to pass through the injector for a specific period

• The spring tension closes the passageway

What occurs after the allotted time ON for the fuel injector?

• The ECM shuts down the entire engine

• The fuel delivery continues indefinitely

• The ECM opens (turns OFF) the electrical circuit, and fuel delivery ends

• The battery takes over the operation of the injector

What takes over to close the fuel injector's passageway when the ECM turns OFF the electrical circuit?

• Hydraulic pressure

• Engine vacuum

• Spring tension

• Manual intervention

What factors are considered in the standard control position for fuel injection rate and timing?

• Engine Speed and Throttle position

• Atmospheric pressure and Temperature

• Shift position and Oil pressure

• Cooling water temperature and Intake pressure

What is the term used to describe adjustments made to the fuel injection amount due to varying environmental and operational conditions?

• Standard control position

• Injection amount

• Correction

• Cruising
