Engine codes

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
After 2000 indicates E85 Ethanol fuel.[citation needed]
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
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 D-4 Gasoline 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

Note: Other manufacturers may modify the engine after it has left the Toyota factory but the engine still keeps the original Toyota designation. For example, Lotus added a supercharger to the 2ZZ-GE in some versions of the Lotus Elise and Exige but it is still labelled 2ZZ-GE, not 2ZZ-GZE.

For Example
4A-GE
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

22R-TEC
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

The use of "G" to denote twin cam engines was decided on in 1971, with the renaming of the 10R into 8R-G. Before, twin cams had received new numerical codes.

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. E.g. 1MZ-FE - This is not a supercharged, narrow angle, fuel injected M-series engine, but a narrow angle, fuel injected MZ-series engine. Confusion is easiest to avoid when using the dash to separate between the engine series and its own characteristics: for instance, 1MZ-FE rather than 1M-ZFE.
