6. Can you explain the difference between a two-stroke and a four-stroke diesel engine? (Technical Knowledge)

Two-stroke and four-stroke diesel engines differ primarily in their operational cycles. The two types of cycles refer to the number of piston movements (strokes) required to complete a single power cycle.

• Two-stroke diesel engine:

  • Completes a power cycle with two movements (up and down) of the piston during one crankshaft revolution.
  • In a two-stroke engine, there is a power stroke every revolution which makes them capable of producing more power and being more efficient size-wise.
  • They tend to be less fuel-efficient and can be more polluting than four-stroke engines due to incomplete combustion.
  • The engine design is simpler, with fewer moving parts, which can result in lower maintenance costs.

• Four-stroke diesel engine:

  • Completes a power cycle with four movements (two up and two down) of the piston during two crankshaft revolutions.
  • It includes the intake, compression, power, and exhaust strokes, which makes it more fuel-efficient and cleaner in terms of emissions.
  • They are generally larger, heavier, and have more components, which can lead to higher maintenance costs.
  • Four-stroke engines are more commonly used in vehicles that require consistent and efficient power over longer periods.

7. What are your strategies for dealing with difficult or dissatisfied customers? (Customer Service & Communication)
