Puffwagon Gold Donating Members 16,348 Member For: 10y 5m 21d Gender: Not Telling Posted 13/09/16 05:10 AM Share Posted 13/09/16 05:10 AM Ay so I was just reading some stuff about atkinson cycle engine operation and I wondered if we could implement this on our cars? We have access to cam tuning and obviously we can have custom cams made. I haven't done any maths at this point so I can't confirm if it would work and there are a multitude of reasons why it may not work. Surely I'm not the only person to consider this, has anyone put some time and thought into seeing if it could work?

It's quite easy to turn a engine by hand with the plugs out but difficult or impossible in some cases with the plugs in. Easier to turn means less fuel needed to overcome the cylinder pressure. Potato version: Use less fuel when cruising.

Can't wait for the next few days off and get my g6 sorted. then I might be able to tackle the celica 3 Link to comment https://www.fordxr6turbo.com/forum/topic/44361-the-off-topic-thread/page/8187/#findComment-1611691 Share on other sites More sharing options...

I think that would be detrimental to a turbocharged engine though? only good for a motor that runs a high compression ratio? have you heard of this technology? I think this is what we want Link to comment https://www.fordxr6turbo.com/forum/topic/44361-the-off-topic-thread/page/8187/#findComment-1611692 Share on other sites More sharing options...

I think this is what we want Most motors aren't "charged" when they are cruising so I don't think it would matter. Obviously some form of intake cam timing is necessary to make it happen later. Maybe the cam timing is already set like that? I have no idea but I'll have a look eventually.

Experience , sure, but they're closer to alzheimer's than anything truly useful.
