Engine code
Engine code
While trying to look into different engine i thought i could share some info with you
4 = 4th engine design in that family
Ax= engine family (most engines at Toyota now have two family character codes, ie 2AZ-FE)
G = head design (G is a sporty head, F is an economy head - relates to horsepower performance, ie. Last gen Celica - 1ZZFE is the base engine (130hp) 2ZZGE is the sport engine (180hp)
Z = Supercharged
T = Turbocharged
E = Fuel injection
S = Direct injection (along with fuel injection - ie 1JZFSE)
C- Equipped with emissions control systems (note: The “C” is not used if the engine was originally equipped for emissions controls.)(The C notation has been associated with California’s (USA), at that time having stricter emission standards)
U- Equipped with emissions control systems for Japan. (The U notation has been associated with the introduction of Unleaded fuel available in Japan at that time)
E- Electronic fuel injection (EFI)
F- Gear coupled cam drive; dual overhead cam (DOHC) engine: timing belt or chain drives
one cam, and “scissors” gear drives the other cam. [Narrow included valve angle]. The split “scissors” gear is a unique way to eliminate gear backlash.
G- Dual overhead cam (DOHC) engine: timing belt or chain drives both cams. [Wide included valve angel]
L- Transversely mounted in vehicle
T- Turbocharged
Z- Supercharged
Also usually the same family motors have the same mounts (4age, 4afe, 4agze)
I will continue looking into info on this over the next few weeks please add info if you can help.
If you go to Wikipedia and type in toyota engines that comes up with a bti more info
