    Honda's F1 Engine

    Fascinating tech.



    Honda has split its turbo, but the way it has done so is different to Mercedes, as the turbo sits within the tight confines of the 'V' of the engine, along with the MGU-H.

    To fit a turbo into this space, it appears that Honda has pioneered the use of an axial flow compressor.

    Rather than a large centrifugal fan, there are a series of smaller fans along a shaft.

    This design spins up quicker, although it may lack the maximum possible boost, which is not such an issue in this fuel-limited formula.

    Aligned on the same shaft as the compressor is the MGU-H and the exhaust-driven turbine; the latter appears to sit behind the engine and is of a more conventional design. Honda hopes to improve driveability and reduce the size of the envelope of the engine with this layout.

    Above the turbo is a compact, low-line aluminium inlet plenum chamber. Inside, the inlets are turned through 90 degrees to reduce the height of the chamber, while still allowing for variable-length inlet trumpets.

    More conventionally, the oil tank and MGU-K are located at the front of the engine and under the left-hand cylinder bank respectively.

    Finally, and again unconventionally, the ERS module ahead of the motor combines the battery and both control electronic boxes (one each for ERS-K and ERS-H) into one unit.

    Doesn't look like it's been a super successful result though?
