Engine codes[edit]

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

  1. The first numeric characters specify the engine block's generation
  2. The next one or two letters specify the engine family
  3. 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.[1]

  • 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.

Diesel[edit]

Starting in 1957 until 1988, Toyota established a separate dealership in Japan dedicated to cars and trucks installed with diesel engines, called Toyota Diesel Store. When the dealership was disbanded, diesel products are now available at all locations, with commercial products exclusive to Toyota Store and Toyopet Store locations.
