What are the measures to improve the efficiency of gasoline engines?
2 Answers
Improving the efficiency of gasoline engines can be achieved through the following measures: Reducing Weight: Remove excess weight from the car by taking out unnecessary heavy items, such as tools stored in the trunk that are not needed, and keep them at home instead. Additionally, having fewer passengers in the car will also reduce its weight, thereby decreasing fuel consumption. Minimizing Resistance: If roof boxes or bicycle racks are not frequently used, remove all items from the roof that obstruct airflow. These items create additional wind resistance, forcing the car to work against the wind. Furthermore, keeping the windows closed while driving can also reduce resistance and improve the efficiency of the gasoline engine.
To improve gasoline engine efficiency, there are several key measures I often discuss with friends. The most straightforward is optimizing engine design, such as increasing the compression ratio to ensure more complete fuel combustion, though this requires higher-octane gasoline. Turbocharging forces more air into the engine, boosting power output. Direct injection technology is also effective, as it directly sprays fuel to minimize waste. Variable valve timing adjusts according to engine speed, reducing fuel consumption. These modifications typically require professional tuning, which may be costly upfront but saves fuel and is more eco-friendly in the long run. Additionally, hybrid systems with electric motor assistance reduce engine load. Regular maintenance to prevent carbon buildup is also crucial to maintaining stable efficiency.
