Dynamic Cylinder Deactivation(DCD) Could be a Good Soltion to This Thread.
I installed DCD Controller in my 4-cylinder 1.6L AT vehicle like Chevy Aveo,
and tested it in stop-and-go mode around the city block, yielding some 10%
to 13% fuel savings. DCD reduces the engine displacement as well as the
engine power when you don't need too much power during city-driving mode,
resulting a limited accelaration when you start from stop. Such kind of saving
is even larger than that of driving under steady speed, which is around 5% to
9%. So DCD could be best suitable for city-driving. Trying is believing. I have
made a 4-cylinder engineering sample called DCD-440 for you guys to try.
