Question 1

Which of the following would be the preferred method of removing a tough-to-remove gasket from an oil pan flange?

Accepted Answer

Pneumatic gasket removers are specifically designed for removing tough gaskets without damaging the flange surface, making them the preferred choice for this task.

Question 2

If a single slab cylinder head is used on an in-line 6-cylinder diesel engine, how many engine cylinders will the cylinder head cover?

Accepted Answer

A single slab cylinder head, when used on an in-line 6-cylinder diesel engine, covers all six cylinders. This design allows for a single component to encompass all the cylinder openings, simplifying construction and potentially improving rigidity and sealing.

Question 3

What recently introduced technology enables the use of aluminum cylinder blocks in light and medium duty diesel engines?

Accepted Answer

Plasma transfer wire arc (PTWA) technology enables the use of aluminum cylinder blocks in light and medium duty diesel engines by applying a wear-resistant coating to the cylinder bores, allowing for lighter engine blocks without sacrificing durability.

Question 4

Technician A says that cylinder block torque twist can be the result of high cylinder pressures. Technician B says that cylinder block toque twist can be the result of drivetrain forces outside of the engine. Who is correct?

Accepted Answer

Cylinder block torque twist can indeed be caused by high cylinder pressures as stated by Technician A, as these pressures can create a twisting force on the engine block during operation. Technician B is also correct in stating that drivetrain forces, which are transmitted back through the engine from components like the transmission and differential, can contribute to torque twist on the engine block.

Question 5

Technician A says that a disadvantage of an induction-hardened parent bore cylinder block is that when a single bore wears, the cylinder block has to be replaced. Technician B says that cavitation erosion is more likely to occur in engines manufactured with parent bores. Who is correct?

Accepted Answer

The answer of Technician A says that a disadvantage of...
