Why is the Vios compression ratio so high?

[DiJayden]

The high compression ratio of the Vios is designed to allow the combustible mixture in the cylinders to burn under lean conditions, primarily serving the purpose of fuel economy and emission reduction. Factors affecting fuel consumption: Potholes on the road will increase fuel consumption. Driving for long periods in low gear will inevitably increase fuel consumption. Neglecting engine maintenance will also lead to higher fuel consumption. Abnormalities in the engine ignition system significantly impact fuel consumption. For example, inaccurate ignition timing, leaking high-voltage wires, or spark plug carbon deposits causing weak ignition can all reduce engine combustion efficiency and increase fuel consumption. Methods to reduce fuel consumption: Reduce vehicle load: Remove heavy and infrequently used items from the trunk to reduce weight. Shift gears promptly: Driving in low gear for extended periods not only slows down the vehicle but also increases fuel consumption, especially when driving on slopes. The shorter the gear shifting time, the more fuel can be saved. Reduce idling time: When driving on urban roads, you often encounter long traffic light waits. Turning off the engine during these times can save fuel.
