What are the differences between the 3-cylinder and 4-cylinder engines of the Lynk & Co 03?

[FranciscoFitz]

Specific differences between the 3-cylinder and 4-cylinder engines of the Lynk & Co 03: 1. Fuel consumption: For engines of the same displacement, fewer cylinders result in less power output. At the same RPM, the volume of air drawn in per unit time is reduced, leading to less fuel injection and lower fuel consumption. Therefore, the 3-cylinder engine is undoubtedly more fuel-efficient than the 4-cylinder engine. 2. Power output: The 3-cylinder engine has one fewer cylinder working compared to the 4-cylinder engine, which reduces mechanical friction and increases thermal efficiency, further enhancing the engine's power output. This compensates for the initial acceleration power deficiency caused by the reduced air intake in the 3-cylinder engine. 3. Low-end torque: For engines of the same displacement, fewer cylinders result in more abundant low-end torque. Each cylinder has a larger volume, with bigger bore and stroke, leading to greater low-end torque. Combined with the reduced turbo lag of the 3-cylinder turbocharged engine, the low-end torque performance of a 3-cylinder turbocharged engine of the same displacement is slightly better than that of a 4-cylinder turbocharged engine.
