A large-displacement car will save fuel than a small-displacement car.

Usually, judging the fuel consumption of a car will refer to the engine displacement, but only looking at the displacement is actually amateur. To judge fuel consumption, it is mainly necessary to calculate horsepower through comprehensive torque. In automobile parameters, the performance of the vehicle is always evaluated by horsepower, because horsepower can be the most intuitive comprehensive kerb quality to judge the thrust-to-weight ratio;

Metric horsepower is commonly used in China, and its concept is that 1PS (horsepower unit) can drive 75KG objects to travel at a speed of one meter per second, so 2 horsepower can reach a moving speed of two meters per second under the premise of constant weight, and if only the speed of 1m/ 1s is needed, the engine can output 1 horsepower, so that.

It is the throttle of the car that controls the intake. Throttle does not really directly control fuel injection, but controls the opening of throttle. The larger the throttle opening, the larger the intake air and the more fuel injection.

When both of them increase at the same time, great heat energy will be generated after combustion, and the speed of pushing the piston to drive the crankshaft will also increase. The speed of the crankshaft is the speed of the engine. Bottom line: The deeper the engine throttle, the higher the speed, the higher the speed, the greater the fuel injection quantity and the higher the fuel injection frequency.

Expressway driving always requires frequent overtaking and merging, because there will always be vehicles driving at high speed on the expressway, and medium and heavy trucks and medium and large buses will also flow on the expressway.

Turtle speed vehicles will seriously affect safety, and these vehicles can ensure safety through the principle of rapid overtaking; Medium and heavy vehicles are undoubtedly steel behemoths on the road, and it will feel great pressure to run parallel with such vehicles. Moreover, if such vehicles lose control in the parallel process, they will tear up small minibuses like pieces of paper.

Of course, the horsepower of 1.5T can still be comparable to that of the mainstream 2.0L, but the performance experience must be improved, because as long as the vehicle weight (kerb quality) is the same, regardless of the influence of transmission system and drive system, the fuel injection quantity of 2.0T and 2.0L in each speed range is definitely the same.

When cruising at the same speed, the fuel consumption will be higher than 1.5T because the torque of the 2.0L engine is too small, which is also the reason why turbocharging technology is popular.
