My CRV and engine sounds

    Hello everyone!

    I have a 2010 Honda CRV and it was made in Japan according to what the
    dealer told me, based on the VIN number. I noticed that it seems a lot
    more quiet when I rev the engine when I am driving it. I had
    previously test driven another 2010 Honda CRV at the dealer which was
    made in the US before I bought this one, and that one was a lot more
    throaty sounding, and it was also brand new, same model. Is this
    something that is a known occurrence? I was just wondering if anyone
    else has noticed this? Mine is much more quiet sounding when I drive
    it fast from a red light for instance.

    Thanks so much,

    Jill :)

    more quiet when I rev the engine

    Many possible causes.e.g.
    i) petrol used can be different : 1 brand can be thicker than another, so
    ( unless a surfactant is added ) will produce coarser vapour which can't
    burn as fast as finer vapour from another brand. Some brands have
    more detergent, so fuel injectors are cleaner, will produce finer vapour
    = less noise & more torque.
    ii) muffler used can be different : some will reduce noise > others.
    iii) spark plugs with resistors will produce smaller sparks = slower
    combustion & so more noise.
    iv) oil used can affect noise : a thinner / slipperier oil can cool cylinder
    head faster, so air intake & fuel injected & alternator are all cooler
    then sparks are bigger so combustion is faster so quieter.

    With your engineering brilliance it's a wonder you don't work for an
    automaker in the highest capacity imaginable.

    and helpful just like me!

  6. What about the influence of the clock?

    Not to mention the "voices" talking in the OP's head! I wonder how
    those tires are working out now that there's snow and if the engine
    noise helps or detracts from her traction?

    Saw that oldie pop up yesterday and wondered if my mail was messed up or
    the newsgroup just burped. Guessing it's the latter.
