[6] CENTER DIRECT INJECTION SYSTEM (E-CDIS)
The 07 series DI engine adopts the Center Direct
Injection System (E-CDIS), in which the injector (3) is set
upright at the center of the cylinder.
This system serves to inject fuel directly at the center
of the cylinder. By so doing, injected fuel and suction air
can be mixed more uniformly, leading to more stable,
higher combustion performance. In other words, cleaner
emission, higher power output, lower fuel consumption,
lower operating noise and higher start-up performance
have been achieved.

The 07 series DI engine has two intake valves and
two exhaust valves per each cylinder.
The rocker arm (1) contacts a valve bridge arm (2)
instead of the valves stem tip.
The valve bridge arm (2) then contacts both intake
valves or both exhaust valves and causes two valves to
open simultaneously.

[7] GEAR TRAIN CONFIGURATION
The 07 series DI engine employs gear train located
at flywheel side. The following benefits are in the rear
gear train configuration.
1. Flexibility of auxiliary parts arrangement.
2. Reduction of gear chattering noise from crankshaft
of torsional and bending vibration.
