This is a list of piston engines developed, independently or with other car companies, by Toyota Motor Corporation.


Engine codes


Toyota has produced a wide variety of automobile engines, including four-cylinder and V6 engines. The company follows a naming system for their engines:

  1. The first numeric characters specify the engine block's model (usually differed by displacement)
  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.[citation needed]
CCarbureted / California Emissions Controlled
DTwin downdraft carburetors or Toyota engines manufactured by Daihatsu without VVT-i (e.g., 1KR-DE)
EMulti-point fuel injection
FNormal cylinder head DOHC
GPerformance cylinder head DOHC
HHigh compression
High pressure charged (example : 2L-THE)
ISingle-point fuel injection
JAutochoke (Early models) or pollution control for commercial cars in Japan
KOn-demand Atkinson cycle in non-hybrid engines
LTransverse
MPhilippines' market (meaning unknown)
NCNG fuel
PLPG fuel
RLow Compression (For 87 and below octane fuel)
SSwirl intake (1980s)
D4-S Gasoline direct injection
TTurbocharged
UWith Catalytic converter Japan-spec emissions
VD-4D Common rail direct injection system (diesel) or Toyota engines manufactured by Daihatsu with VVT-i (e.g., 1NR-VE)
XHybrid Atkinson cycle
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.

Examples:

The use of "G" to denote twin cam engines was decided on in 1971, with the renaming of the 10R into 8R-G. Before that, twin cams had received separate numerical codes.[1]

Note:

Dynamic Force engine series:

The Dynamic Force engine series introduced a partially different naming scheme.

Examples:


Gasoline



Flat-twin or Flat-four

V12



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.
