What is the difference between 1.5L and 2.0L engine displacement?

[OIker]

The differences between 1.5L and 2.0L engine displacement are: 1. Different exhaust emissions, with 2.0L displacement vehicles emitting more exhaust than 1.5L displacement vehicles; 2. Different engine power, with 2.0L displacement engines having greater power than 1.5L displacement engines; 3. Different fuel consumption, with 2.0L displacement engines generally consuming more fuel than 1.5L displacement engines. Here is additional information: Compared to 2.0L displacement engines, 1.5L displacement engines have lower maintenance costs in the long run because 2.0L displacement engines have larger volumes, requiring more fluids to support their operation. 1.5L displacement vehicles have weaker initial acceleration but higher fuel efficiency, with fuel consumption around 6L, while 2.0L displacement vehicles have stronger power, leaning towards sportiness, but with relatively higher fuel consumption.
