What is the most extreme valve lift you've seen on a Type 4 engine?
Thanks in advance. |

IIRC, the Miller cycle is all about asymmetric expansion/compression ratios. Where you get more effective expansion than compression, something like that. And it is good for efficiency in terms of power output per fuel burned, but not so great for specific power.
...I hope I'm not mixing that up with a different cycle... --DD |
