List of Toyota engines

Engine codes

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
AValvematic variable lift intake head
BBefore 2000 indicates twin SU-style side-draft carburetors
After 2000 indicates E85 Ethanol fuel.
CCarbureted / California Emissions Controlled
DTwin downdraft carburetors
EElectronic fuel injection
FEconomy narrow-angle DOHC
GPerformance wide-angle DOHC
HHigh compression
High pressure charged (example : 2L-THE)
ISingle-point fuel injection
JAutochoke (Early models) or unknown pollution control
KAtkinson cycle
LTransverse
MPhilippines' market (meaning unknown)
NCNG fuel
PLPG fuel
RLow Compression (For 87 and below octane fuel)
SSwirl intake (1980s)
D-4 Gasoline direct injection
TTurbocharged
UWith Catalytic converter Japan-spec emissions
VD-4D Common rail direct injection system (diesel)
XHybrid
ZSupercharged

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

2NR – 2nd generation engine in the NR engine family
F – Economy narrow-angle DOHC
E – Electronic fuel injection

1ND – 1st Generation Engine In The ND Engine Family
T – Turbocharged
V – D-4D common rail direct injection (diesel)

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]

Diesel

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.

Toyota has not published an explanation of the codes used for engine features. Matti Kalalahti derived a list of engine feature codes and published them on his "Engine codes explained" web page in Oct 1999.
