Intake valve open on compression stroke??
I was reading the Civic review in the Jan 06 edition of Autocar India.
In it, the writer mentions that Honda have adopted a new tech in their VTEC system. Apparently, it leaves the intake valve open a little during the compression stroke to help reduce strain on the engine or something like that.
Wouldn't leaving the intake valve open during compression lead to a loss of compression? How does this work?

This is done only during part throttle to reduce pumping loss. The throttle is opened more to compensate for this. Remember, in a flyby wire system there is no connection between your foot and the throttle plate.
