What all is included in engine tuning(building, not modifiying)? - engine tuning
What exactly in the setting of the engine (mechanical engineering) is involved? I know that the diameter of the cylinder, the engine speed and compression is the power relation, as the air-fuel ratio and what not. I also know that the days is akin to the crankshaft, pressure and air / fuel ratio, the couple. But I am curious what determines things such as power, torque and fuel efficiency.
In the examples of a 2.0-liter engine with a 5spd manual transmission and 135 to 130 hp lb-ft TQ and 33 mpg on the highway, when given a 4.6-liter engine with a 5spd manual transmission, 260 horsepower can and use 302 lb-ft tq and 25 mpg. I think, from the MPS, because the engine is bigger and had more power, but a 5.7-liter engine and a 6spd manual transmission 350 hp and 365 lb-ft TQ and can get 29 mpg highway. This is what puzzles me, even if there is more than 1.1 liters in displacement of 4.6, it is driven more gas, almost as much as the first machine is larger than 3.7 liters.
Why is this so?

The most important thing you must understand is that gasoline consumption is not only made by the engine, but also by the car itself. Commercial vehicle weight affects gas mileage, such as the aerodynamics of the car.
