    2. The FA20 uses the Direct injection 4-stroke gasoline engine Superior version (D-4S) system to achieve high performance while also achieving fuel economy and clean emissions. The features of the D-4S system are as listed below:


      1. The D-4S system is a system which combines a direct injection system which injects fuel into the combustion chamber and a port injection system which injects fuel to the intake ports. This system optimally controls the 2 types of fuel injectors in accordance with the driving conditions.

      2. When the engine is running under a medium or high load at lower speeds, both the direct and port injection systems are used. This control creates a homogeneous air-fuel mixture to stabilize combustion, improve fuel efficiency, and reduce emissions.

      3. When the engine is running under heavy load, the direct injection system is used. This achieves an intake cooling effect by injecting fuel directly to the combustion chamber. As a result of this cooling effect, the compression ratio of the engine can be made higher as the tendency of the compressed mixture to preignite or detonate is reduced. The increased compression ratio improves engine output and performance.

      4. The slit nozzle type direct injection injectors atomize fuel so that the fuel spreads out widely and finely in a fan shape. Fuel is mixed with intake air efficiently and homogeneously, aiming at ideal combustion under any driving conditions.

      5. When the engine is cold, fuel is injected from the injectors (for port injection) to create a homogenous lean air-fuel mixture in the combustion chamber. Fuel is also injected from the injectors (for direct injection) during the latter half of the compression stroke to adjust the air-fuel mixture around the spark plug to allow stable combustion under retarded ignition timing, thus increasing exhaust gas temperature. This promotes rapid warming of the catalysts and achieves cleaner emissions.
