Does the car use engine brakes to increase fuel consumption?
That is, "drag the file to go" - hanging file does not give oil, the engine has no traction on the car.
On the contrary, due to the rotation of the wheel drive the drive system, the engine under the idle speed of the car to produce the reaction of the resistance, the higher the engine the role of the smaller car, the greater the contrary.
2, the use of engine brake is to lift the accelerator pedal, but do not step off the clutch, the use of the engine compression stroke compression resistance, internal friction and intake and exhaust resistance to the drive wheel to form a braking effect.
1, now most of the vehicles are EFI, so the use of engine braking, as long as the speed is reasonable, it will not increase fuel consumption, of course, not to say that no oil, but rarely very little.
