How is a 3-cylinder engine for long-distance driving?
2 Answers
There is no major issue with using a 3-cylinder engine for long-distance driving. Advantages of a 3-cylinder engine: 1. Low fuel consumption: Due to its structural advantages, a 3-cylinder engine performs exceptionally well in terms of fuel efficiency. The engine is smaller in size but has a higher power density and thermal efficiency, resulting in lower energy loss during operation and reduced fuel consumption. For consumers who prioritize fuel efficiency when purchasing a car, a 3-cylinder engine is worth considering. 2. Strong power output: Among small-displacement engines, a 3-cylinder engine has a larger single-cylinder volume compared to engines of the same displacement, providing more sufficient power at low RPMs. The reduced number of cylinders also decreases mechanical friction, leading to faster power response and stronger performance in some small-displacement engines compared to 4-cylinder engines. 3. Reduced turbo lag: Compared to a 4-cylinder engine, a 3-cylinder engine has less exhaust interference. Combining turbocharging technology with a 3-cylinder engine results in better low-end torque and reduced turbo lag, enhancing the vehicle's overall power performance.
I once took a long-distance trip in a three-cylinder car, driving nearly 1,000 kilometers from Beijing to Shanghai. The fuel consumption was indeed low, using less than 40 liters for the entire trip, averaging just over 6 liters per 100 kilometers. The vibration was a bit annoying, with noticeable engine noise on the highway, and my wrists felt uncomfortable after long drives. In terms of power, it performed fine on flat roads but required accelerating in advance for steep slopes. Maintenance was straightforward—regular oil changes kept it running smoothly. If you frequently take long trips, adding some soundproofing strips might help to avoid fatigue. Overall, it's suitable for cost-conscious owners, but don’t expect too much in terms of comfort.
