A truck manufacturer must choose an engine suitable for heavy-duty transport applications. Based on a comparative study, which engine type is generally preferred?
Four-stroke compression-ignition engine
Heavy-duty transport needs an engine with high torque at low speed, durability, and good fuel economy over long hauls.
The four-stroke compression-ignition (diesel) engine runs at a high compression ratio, giving strong low-speed torque and superior thermal efficiency.
Its rugged four-stroke construction withstands continuous heavy loads better than lighter spark-ignition or rotary designs.
Two-stroke and four-stroke spark-ignition engines burn more fuel and give less low-end torque, and the Wankel rotary is unsuited to sustained heavy duty, so they are not preferred.
Hence, the answer is Four-stroke compression-ignition engine.
