Miller timing vs F timing

Miller timing vs F timing

Miller timing vs F timing

(OP)
Hi guys,
Can any one explain the different between miller timing and f-timing.

RE: Miller timing vs F timing


What's "f-timing"?

RE: Miller timing vs F timing

I think I know what Miller time is.

RE: Miller timing vs F timing

Miller Time = Feier Abend! thumbsup2 cheers

FOR ENGINEERING PROFESSIONALS That's the motto of this forum.
With the said i deal the electrical side of diesel generator and someone said that this generator don't have miller timing, it have f-timing,because i never heard of the timing i decide to asking and do my own research but it came up negative.

RE: Miller timing vs F timing

Let your own research in future include Google, which produced some interesting hits on "timing a Diesel miller" without the quotes.

Let your own first questions here in future include a context, e.g. Diesel engines,
and some indication of what you have done to help yourself,
and core results from your research.


... else you will be mocked.

... for which I will not apologize.

The back and forth joking does occasionally break loose enough detritus to fill in the holes in the original question, and allow generation of an answer. ... which is very occasionally correct.

RE: Miller timing vs F timing

Here is a link with an excellent paper regarding applying a miller cycle to a diesel engine,

Here is another paper describing comparison between Miller, Otto and Diesel cycle engines.

I have no idea what you mean by "f-timing".

Perhaps some more detail like what engine make and model you're referring too, as a number on manufacturers are starting to offer 4 stroke miller cycle gas and diesel engines as emissions regulations become more strict.

RE: Miller timing vs F timing

Redline - certainly no mock intended on my part. I take quite an interest in novel engine cycles and strategies and I have never heard of "f-timing" - neither has the internet from what I could see.

RE: Miller timing vs F timing

More details on what F-Timing is......This post lacks necessary info if you want an "Intelligent.....Professional" discussion.

RE: Miller timing vs F timing

I would ass-u-me that since Miller timing uses variable valve timing that f-timing would be Fixed timing. :)

RE: Miller timing vs F timing

That is a not-entirely-unreasonable guess ... except that it is not strictly necessary to use variable valve timing in order to implement Miller/Atkinson!

Most production implementations do use VVT in order to minimize the bad side-effects of Miller/Atkinson, e.g. the VVT is used to reduce the Miller/Atkinson effect near full load so that the engine will actually have a decent torque output, instead of a hamstrung torque output, and increase the effect at part load when the driver is not asking for the torque anyways.
