    Toyota Engines

    Post by dp on Sat Mar 21, 2009 6:15 pm

    Toyota Motor Corporation has produced a wide variety of automobile engines. The company follows a simple naming system for their modern engines:

    The first numeric characters specify the engine block's generation
    The next one or two letters specify the engine family

    The suffix (separated by a dash) specifies the features of the engine:
    Suffix Feature

    A Valvematic variable lift intake head
    B Twin SU-style side-draft carburetors
    C Carburated / California Emissions Controlled
    D Twin Downdraft carburetors
    E Electronic Fuel injection
    F Economy narrow-angle valve DOHC
    G Performance wide-angle valve DOHC
    H High compression like 9.8:1 (example: 5E-FHE)
    High pressure charged (example: 2L-THE)
    I Single-point fuel injection
    J Autochoke (Early models) or unknown pollution control
    L Transverse
    M Philippines' market (meaning unknown)
    N CNG fuel
    P LPG fuel
    R Low Compression (For 87 and below octane fuel)
    S Swirl intake (1980s)
    SE Direct injection (1990s)
    T Turbocharged
    U With Catalytic converter Japan-spec emissions
    V Common Rail Diesel Injection (D-4D)
    X Atkinson cycle (typically also indicates a Hybrid engine, as Toyota only uses the Atkinson cycle with hybrids)
    Z Supercharged

    For Example

    4 - 4th Generation Engine In The A Engine Family
    A - The Engine Family it is in
    G - Wide-angle dual camshaft
    E - Electronically Fuel Injected

    22 - 22nd Generation Engine In The R Engine Family
    R - The Engine Family it is in
    T - Turbocharged
    E - Electronically Fuel Injected
    C - California Emission Controlled

    (Note: Toyota, in 1987, began assigning dual letter engine codes to some of the "engine family" categories in some engine lines, particularly six cylinder models. This can create potential confusion. Eg. 1UZ-FE - This is not a supercharged, narrow angle, fuel injected U-series engine, but a narrow angle, fuel injected UZ-series engine. Confusion is easiest to avoid when using the dash to separate between the engine series and its own characteristics: for instance, 1UZ-FE rather than 1U-ZFE)
