What is the compression ratio of the new Sylphy?
2 Answers
The compression ratio of the new Sylphy is 9.8:1. What is compression ratio: Compression ratio refers to the degree to which the engine's mixed gas is compressed, expressed as the ratio of the total cylinder volume before compression to the total cylinder volume after compression. High compression ratio engine: A high compression ratio engine can better utilize the working characteristics of a piston engine. During the power stroke, the same amount of fuel can generate greater power, and a smaller displacement can achieve the power that previously required a larger displacement engine. In other words, a high compression ratio engine has higher power per liter and better fuel efficiency.
The compression ratio of the new Sylphy is approximately 10.5:1, which is a relatively ideal figure. I've noticed that this high compression ratio significantly improves engine efficiency; during driving, the acceleration response is quite quick, and fuel consumption can be maintained between 5-6L/100km. However, using high-octane gasoline, such as 95 octane, is crucial to prevent knocking issues. For long-term maintenance, I recommend regular oil changes and spark plug inspections to keep the compression system healthy. From my experience, this car is well-balanced in design, finding a good compromise between performance and economy.
