正确说法

• 该发动机标称输出功率为五百马力，但在实际路况中，受驾驶条件和油耗限制，有效输出通常低于这一数值。(The engine has a rated output of 500 horsepower, but under real road conditions the effective output is usually lower due to driving conditions and fuel consumption constraints.)
• 新生产线安装调试完毕后，工厂立即开足马力运转，力求在季度末前完成所有积压订单。(After the new production line was installed and commissioned, the factory immediately ran at full capacity, striving to complete all backlogged orders before the end of the quarter.)

错误说法

• 将马力与千瓦混用而不注明换算关系 — 马力 (HP) and 千瓦 (kW) are both units of power but not interchangeable without conversion; 1 HP ≈ 0.746 kW — always specify the unit clearly in technical writing
