What is the fuel consumption per 100 kilometers for a 1.8L engine?
2 Answers
Generally, the fuel consumption per 100 kilometers for a 1.8L sedan is around 8-10 liters. Below are the specific reasons for high fuel consumption in cars: 1. Temperature influence: Fuel consumption fluctuates due to temperature changes. In winter, lower temperatures lead to slightly higher fuel consumption. 2. Lack of maintenance: Dirty engine oil and air filters can also increase fuel consumption. Dirty oil reduces lubrication efficiency, increasing resistance in the engine's moving parts, which requires more energy to overcome, thus raising fuel consumption. 3. Insufficient tire pressure: Low tire pressure increases the contact area between the tires and the road, leading to higher friction and driving resistance, which increases fuel consumption. 4. Excessive carbon buildup: Carbon deposits in areas such as the throttle valve, fuel injectors, intake ducts, and piston tops can cause incomplete combustion, leading to higher fuel consumption.
To be honest, fuel consumption per 100 kilometers can't be judged solely by the 1.8L displacement figure. Having driven for over a decade, I can say larger displacement engines generally consume more fuel than smaller ones, with 1.8L cars averaging around 8 to 10 liters per 100 kilometers. But this depends on specific vehicle conditions and circumstances: in congested urban traffic, it might spike to 12 liters, while smooth highway driving can reduce it to about 7 liters. Vehicle weight and design are also crucial—SUVs are thirstier than compact sedans. I once drove a 1.8L Japanese car where the fuel gauge dropped rapidly in city traffic with frequent traffic lights, and using air conditioning added to the burden. I recommend consulting the owner's manual or real-world app data more often, as driving habits like sudden acceleration and frequent braking can skyrocket fuel consumption, while proper maintenance of tires and filters can save a lot of money.
