Engine codes

Toyota has produced a wide variety of automobile engines, including three-cylinder, four-cylinder, V6 and V8 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:
SuffixFeature
A Valvematic 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 (e.g., 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
L Transverse
MPhilippines' market (meaning unknown)
N CNG fuel
P LPG fuel
RLow Compression (For 87 and below octane fuel)
SSwirl intake (1980s)
D-4S gasoline direct injection
T Turbocharged
UWith catalytic converter Japan-spec emissions
VD-4D diesel common rail direct injection system
Toyota engines manufactured by Daihatsu with VVT-i (e.g., 1NR-VE)
XHybrid Atkinson cycle
Z Supercharged

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 the engine 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]

In 1987, Toyota 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.

Starting in 2015, the designations after the dash have a maximum combination of three letters, even though there are more suffixes applicable, especially when newer engine technologies are introduced. For example, both the 2GR-FKS and 8AR-FTS engines have electronic multi-point fuel injection, but the "E" suffix is not included in the code.

Dynamic Force engine series

The Dynamic Force engine series introduced in 2017 uses a naming scheme similar to that used by Honda and Suzuki. The two numbers between the first and second letters denote the displacement of the engine in liters. The suffix denoting the features of the engine is still used, as with prior engines.

Examples:

Some engines don’t share the same displacement as with the one found in the engine code. For example, the displacement of the V35A-FTS is closer to 3.4 L despite being marketed as a 3.5 L engine. Moreover, there are a few engines that use the naming scheme of the Dynamic Force family of engines but are not actually part of them, such as the diesel-powered F33A-FTV and the Gazoo Racing G16E-GTS.

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 Motor Corporation's M family of engines were a longitudinally mounted straight-6 engine design. They were used from the 1960s through the 1990s. All M family engines were OHC designs. While the M family was born with a chain-driven single camshaft it evolved into a belt-driven DOHC system after 1980. All M family engines used a cast-iron block with an aluminum cylinder head, and were built at the Toyota Kamigo plant in Toyota City, Japan.

<span class="mw-page-title-main">Multi-valve</span> Type of car engine

A multi-valve or multivalve engine is one where each cylinder has more than two valves. A multi-valve engine has better breathing, and with more smaller valves may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power.

The GM Family I is a straight-four piston engine that was developed by Opel, a former subsidiary of General Motors and now a subsidiary of PSA Group, to replace the Vauxhall OHV, Opel OHV and the smaller capacity Opel CIH engines for use on small to mid-range cars from Opel/Vauxhall. The engine first appeared in the Opel Kadett D in 1979, and shortly afterwards in its Vauxhall badged sister – the Vauxhall Astra Mk.1 in 1980. Despite this, the previous Opel OHV engine continued to be sold in entry level versions of the Opel Kadett/Astra and Corsa throughout the 1980s.

<span class="mw-page-title-main">Fiat 128 SOHC engine</span> Reciprocating internal combustion engine

Designed by Aurelio Lampredi, the Fiat SOHC engine first appeared in the front-wheel drive (FWD) Fiat 128 of 1969. The in-line four-cylinder engine comprised an iron block with an aluminium cylinder-head containing a single overhead camshaft operating directly on both the inlet and exhaust valves in a reverse-flow cylinder-head configuration. The camshaft was driven by a toothed belt rather than chain. The engine remained in production until about 2010 and grew in capacity over the years from 1100 cc to an eventual 1900 cc. The Fiat 130 2.9 L (2,866 cc) V6 engine, also appearing in 1969, although having crossflow cylinder head, is directly related to the 128 SOHC engine, but with a 1.20 upscale in bore and stroke. The 128 SOHC engine was gradually replaced by the Pratola Serra engine series starting from 1995, and in the 1100 cc guise, by the FIRE unit of comparable displacement. It was also converted to use a multivalve DOHC head, giving birth to the Torque engine, used until 2005.
