By improving and precise fuel injection control of the anti-knock limit by this direct injection,
High compression ratio was impossible in previous turbo engines, high efficiency.
And the overwhelming sport performance that surpasses the large displacement turbo engine vehicles yet 2.0ℓ, we can achieve both low fuel consumption and low exhaust emissions that can not be imagined from its power. It is as there are customers to worry about whether to any type of vehicle in the engine and price.

In the direct-injection turbo engine, it just has to hand the appropriate performance to be called next-generation sports unit.
Although the format is the very same as the FA20 for the BRZ, common to that of the bore × stroke and the crank shaft, about fine around head parts. Others are totally different thing.

FA20 DIT also has become a direct-injection engine, but but, system adopts Subaru own in-cylinder injection system rather than D4-S. In the direct injection system, the air-fuel mixture to the intake air into the combustion chamber in order to longitudinal vortex flow (tumble), TGV (tumble generator Federated valve) and the intake port with a septum, that the tumble-oriented intake port has been adopted is the topic . TGV comprises a valve for generating positively vertical vortex flow even at low rotation region, and increase the combustion efficiency.

For the BRZ for a high-rotation type naturally-aspirated engine of, FA20DIT has become a specification that squeeze out the power and torque from the low rotation by providing a supercharger. Intake layout seems different points greatly also FA20 for the BRZ has become the conventional similar rear intake air layout in relation to the turbine and intercooler installation. By the way, FA20 but also to XT system of Forester are installed, here according to the Forrester of character is a SUV, maximum output are kept to 280ps.

Briefly, the FA20 boasts a sporty characteristics by the square bore × stroke, equipped with a direct injection system in the cylinder.

And enables optimal fuel injection for the operation range, the intake air amount increases with a high compression ratio, was significantly enhanced combustion efficiency. Further adopted a new design of twin scroll turbo and dual AVCS (variable valve timing), as well as both an overwhelming output characteristics and excellent fuel efficiency, is possible to achieve the early activation of the catalyst, also achieved excellent exhaust performance you have.

ransmission to be combined has developed a dedicated linear Toro Nick that corresponds to the high torque.
When the SI-DRIVE “I” or “S” selected in the running in the D range, equipped with a new control switching to step speed when the accelerator is a high degree of opening, provides a linear acceleration.
“S♯” When selecting a step shift control of the eight-stage cross-ratio, Masu fun Me a more sporty acceleration and direct speed.

Also Revogu, in WRXS4, In addition to increasingly improve the fuel efficiency due to the adoption of the charge control system, raising the Revurimitto up to 6500rpm, it has evolved into a further sporty engine. Linear Toro Nick also, such as the finish to the moment in which the shift operation to the sporty characteristics of the engine and the meter will react, we further enhance the joy to manipulate.
