There seems a Mr. TCD who keeps saying that DCD is not as good as TCD.
But his knowledge seems coming from thermodynamics only, not from control
electronics. Moderm engine is controlled by ECU, by oxygen sensor, by closed
loop. DCD needs even more controls, by DCD controller, by WBO2 sensor, by
high-lambda loop, by multiple lambda set points. If you don't know all of the
basic knowledges, your comment on DCD could become unreasonable. I won't
teach you everything related to DCD. You may wish go to read some
textbooks before making qualified speach.

I'm talking about the benefits of DCD because I invented DCD, I did my
contribution to this world. What about you, Mr. TCD? Did you join the actions
in 1970s and 1980s in TCD invention? Or you had made any TCD controller
by which TCD aftermarket retrofitting can be implemented. How many TCD
engines have you implemented or retrofitted? Show all of us your qualification.
You sound like a professor of thermodynamics, yeilding top score in this field.
But you should know that's only 1/3 of the engine related knowledge.

DCD technology is chanllenged by TCD and Mr.TCD. DCD is not afreid of TCD.
Let's wait to see who will beat who? who has more installation? who has
higher utilization? who has higher overall fuel savings? Mr.TCD should know
overall fuel savings comes from the contribution of these factors, not the
single one from thermodynamic analysis.
