What is the compression ratio of the Bestune T77 gasoline engine?

The compression ratio of the Bestune T77 gasoline engine is 11.5. To illustrate the technical parameters of an engine, one can generally use the magnitude of power and torque as indicators. However, there are many factors that influence the output of power and torque, one of the key factors being the engine's compression ratio. Below is more information about the compression ratio of the Bestune T77 gasoline engine: 1. The compression ratio indicates the degree to which the gas in the cylinder is compressed when the piston moves from the bottom dead center to the top dead center. 2. During the operation of an internal combustion engine, as the amount of air and fuel in the cylinder decreases, the ignition of the engine tends to become irregular. Conversely, as the fuel-air mixture increases, it becomes more prone to knocking, thus limiting efficiency. As one of the important parameters that can influence factors such as torque, fuel economy, and emission indicators, the compression ratio is key to solving this issue. Therefore, selecting an appropriate compression ratio to achieve a balance among these parameters is a crucial method for enhancing the performance of internal combustion engines. 3. When a gasoline engine is running, it typically draws in a mixture of gasoline and air. During the compression process, as the piston moves upward, it not only compresses the mixture to reduce its volume but also generates phenomena such as swirl and turbulence.
I've been driving the Bestune T77 for several years. The engine compression ratio is 9.5:1, which is a fairly standard setting. It's quite fuel-efficient for city driving, averaging around 7 liters per 100 kilometers, but the explosive power on highways is slightly weaker. The relatively low compression ratio means 92-octane gasoline is sufficient—no need for higher-octane fuel, saving money and hassle. For maintenance, I regularly check the spark plugs and ignition system to prevent carbon buildup from affecting compression efficiency. If the power feels weaker than before, it might indicate a change in compression ratio, so it's best to get it checked immediately to avoid engine damage. Overall, this design emphasizes economy, making it very reliable for daily commuting.
