According to its characteristics in terms of dynamics and fuel consumption, it is no different from the T18SED. Some parts and components of the engine underwent transformations: the timing drive, rollers, belt, oil filter was moved to another place, the pump, the engine received a single ignition module.
The F series also includes engines: F14D3, F14D4, F15S3, F16D3, F16D4 and F18D4.
