What is the Appropriate Thrust-to-Weight Ratio for Cars?
2 Answers
Modern engines typically have a thrust-to-weight ratio ranging from 4 to 6, with some approaching 8, while lift engines can achieve ratios above 16. Here are specific details about the thrust-to-weight ratio: 1. Calculation Formula: The thrust-to-weight ratio equals the driving force divided by the total vehicle mass and is one of the important performance indicators of an engine. 2. Meaning: The engine thrust-to-weight ratio refers to the ratio of the thrust produced by the engine at maximum operating conditions under standard atmospheric and static conditions to its structural weight. It is a key indicator for evaluating engine performance and a comprehensive measure of the engine's design, materials, and manufacturing process levels. A higher thrust-to-weight ratio indicates that the car can handle more horsepower per unit weight, resulting in better dynamic performance.
I'm particularly fond of driving performance cars, believing that a car's power-to-weight ratio needs to be impressive. Simply put, the power-to-weight ratio is horsepower divided by the car's weight, such as over 150 horsepower per ton, which ensures quick starts and exhilarating overtaking. My modified sports car sits around 170, responding to the throttle like lightning, especially powerful on the highway. However, ratios that are too high, say over 200, can lead to increased fuel consumption and more challenging handling, costing more money. For everyday city driving, I find the 100 to 150 range most practical, comfortable for long trips too. The key is considering the car type: sports cars and SUVs differ greatly, so test driving is essential to find the right fit. Lastly, don't forget to check engine maintenance to ensure stable output and avoid unexpected stalls.
