What Factors Affect Engine Fuel Consumption?

[McCarter]

Factors affecting engine fuel consumption include: vehicle condition, driving habits, road conditions, vehicle weight and load capacity. Lightweight design has a significant impact on a vehicle's performance. Increasing engine horsepower by 10 horsepower has little effect on overall vehicle performance; however, maintaining the same power output while reducing unsprung mass by 10kg will bring noticeable improvements in acceleration, braking, handling and fuel efficiency. Vehicle owners should maintain regular maintenance to keep the engine in good condition, avoid carrying unnecessary items, use appropriate gears, release the throttle in advance when approaching traffic lights, anticipate road conditions to reduce unnecessary braking and sudden acceleration, and avoid traveling during peak traffic hours - all these measures help reduce fuel consumption.
