How is the Buick Excelle three-cylinder engine?

[MacHarmony]

Here is a detailed introduction to the Excelle's three-cylinder model: 1. The three-cylinder engine of the Excelle has been optimized during production, such as adding balance shafts to reduce vibration and installing soundproofing materials in the engine compartment to minimize noise. 2. These measures help mitigate the inherent weaknesses of three-cylinder engines, bringing their performance closer to that of four-cylinder engines in these aspects. 3. Apart from the engine, other parts of the car are well-designed. Below is a specific introduction to the three-cylinder engine: 1. The advantage of a three-cylinder engine is fuel efficiency; three cylinders working may consume less fuel than four cylinders. 2. The disadvantage is the inherent imbalance of three-cylinder engines, which leads to vibration and noise. 3. When pursuing power, the wear and tear on a three-cylinder engine is greater, resulting in a shorter lifespan compared to a four-cylinder engine.
