    Low Fuel Consumption

    Bro ..
    bantuin gue donk, gue ada yang gak ngerti dari penggalan artikel di sebuah web nih:

    """""
    Note that the manifold pressure increases as the air/fuel ratio is made leaner. To obtain the same power output with a leaner mixture, you have to use more throttle. Generally, fuel consumption decreases as the mixture is made leaner. Eventually the increase in manifold pressure offsets the reduction in fuel flow and fuel consumption increases once the mixture is leaned past 15.7:1.

    At the stoichiometric air/fuel ratio, fuel consumption is around two percent higher than optimum. Air/fuel ratios richer than stoichiometric sharply increase fuel consumption so that running 13.5:1 results in eight percent more fuel consumption than stoichiometric. This is why it's important to have a correctly functioning oxygen sensor.
    """""

    Yang dimaksud manifold pressure itu apa yah ?
    ada yang tahu informasinya ?

    Gw cuman bisa nangkep dikit yg paragraph pertama sih.
    Manifold pressure mnurut gw yah pressure dari throtte (intake pressure). Jadi kalo ratio air dan fuel dibikin lebih lean, inlet pressure nya itu yg harus dinaekin. Trus fuel consumption akan lebih sdikit.

    Maap nih kalo2x salah. Tap mestinya engga sih. hehehehe.

    yg dimaksud tuh pressure dari IM(intake manifold)temen deket nya TB.
    more throttle=more air=more pressure in the manifold.

    TB itu apaan yak ?

    more throttle = more air, gue setuju ..
