MC and ME-C Engine Reversing Quiz

In an MC engine, reversing is achieved by:

• Electronic control system

• Mechanical shifting of camshaft

• Hydraulic pump reversal

• Manual fuel cutoff

The air distributor in an MC engine reversing process is set to:

• Admit air in the normal firing order

• Admit air randomly

• Admit air in the opposite firing order

• Block starting air

In an ME-C engine, reversing is controlled by:

• Manual levers

• Electronic Control System (ECS)

• Hydraulic pistons only

• Governor

When an astern order is given in an ME-C engine, the ECS first:

• Switches to astern timing immediately

• Cuts off fuel and waits for engine to stop

• Admits starting air directly

• Reverses the hydraulic pumps instantly

Which system provides electrical signals to the solenoid valve of the pilot valve for starting air?

• ACU (Auxiliary Control Unit)

• CCU (Cylinder Control Unit)

• ECU (Engine Control Unit)

• Governor unit

In ME-C engines, reversing the fuel injection timing is done by:

• Adjusting the governor manually

• Shifting camshaft

• Reversing operation of hydraulic pumps

• Delaying the exhaust valve opening

Which of the following components is reversed during ME-C engine reversing?

• Fuel injection timing and exhaust valve actuation

• Starting air distributor only

• Crankshaft rotation only

• Turbocharger operation

The ME-C engine admits starting air during reversing in:

• Random order

• Ahead firing order

• Reverse firing order

• Simultaneous for all cylinders

The MC engine relies on ______ to change firing sequence.

• Software programming

• Mechanical shifting of the camshaft

• Hydraulic pump reversal

• Electronic logic circuits

In the ME-C reversing process, which control unit gives electrical signals for reversing operation of hydraulic pumps?

• CCU

• ACU

• MOP

• ECU
