Valve timings

edit

Does anyone have valve timing info for the 1NZ-FE? It might be informative to put this side-by-side with that for the 1NZ-FXE, as it would illustrate exactly how the 1NZ-FXE is different, as well as providing a good example of a specific implementation of the Atkinson cycle,.

Here are the figures for the 1NZ-FXE (source: Prius NHW20 New Car Features):

Intake valve opening 18° – −15° BTDC
Intake valve closing 72° – 105° ABDC
Exhaust valve opening 34° BBDC
Exhaust valve closing 2° ATDC

Timing diagrams might be nice too.

The following was added:

Production was stopped in 2009, at arrival of Prius III.
In 2012, at arrival of Prius C (North-America), Prius Aqua (Japan), Yaris Hybrid (Europa), a new version occurs.

I'm having trouble interpreting what it means. I assume Prius III means the XW30 generation. Does 'new version' just mean the production line was restarted (with a gap from 2009 to 2012) or was it a new generation (with new mechanical features)?  Stepho  talk  09:34, 27 April 2014 (UTC)Reply
