What are the differences between three-cylinder and four-cylinder cars?

[TuckerRose]

The main differences between three-cylinder and four-cylinder cars are as follows: 1. Fuel consumption: Due to its structural advantages, the three-cylinder engine excels in fuel consumption control. Its smaller size and higher power density result in greater thermal efficiency. The three-cylinder engine also has lower pumping losses due to its structure, and the smaller cylinder size reduces friction and heat dissipation losses during operation. 2. Power performance: In the displacement range of 1.0L-1.5L, the three-cylinder engine has larger single-cylinder volume compared to a four-cylinder engine of the same displacement, providing better low-speed torque. Fewer cylinders mean less mechanical friction, and increasing the number of cylinders can reduce single-cylinder efficiency. Three-cylinder engines offer faster power response and stronger performance compared to four-cylinder engines. 3. Size and weight: Three-cylinder engines are smaller and lighter, reducing overall vehicle weight. Their compact size also saves space in the engine compartment, providing room for electrification components. Four-cylinder engines are larger in size.
