VID was officially approved by KIA MOTORS for it’s commercial value and result where Mr.JS has worked as an engine electric engineer.

Figure (H-1) show two engine’s
different result per load and rpm.

A means “base engine”
B means “VID-adopted engine”
F/L means “Full Load”

We observe three facts
1. Torque improved per constant load and variable rpm
2. BSFC is improved as less fuel consumption per load.
3. Climbing and acceleration capacity must be improved.
