Diesotto engine - any details ?

[rev-erend]

I've seen the recent release from Merecedes about the diesotto
petrol engine.

It's supported to be the next big thing (according to their own PR)..

Offering benefits of petrol and diesel but I cannot find many details.

Such as CR - it says variable displacement - so I'm presuming the CR changes based on hydraulic rams - I presume.

Other stuff like ignition is either convetional spark plug or diesel compression
- I guess based on load / engine speed.

Anyone know more details.

Bit risky Mercedes adding more technology to their cars. You'd think they would try and make the current ones reliable first, before adding more crap !!!!

Yes - I thought it strange.

The generally seem to have quiet old tech engines .. big V8 loads of bhp and torque.. poor mpg etc..

I'm sure they probably paid someone like Ricaro pretty handsomly for the R & D..

Well - I would think they would need to change the CR and not the displacement anyway..

Running at 11:0 in poor area's and 15 ~ 18 : 1 if you want to be a diesel..

Looks like HCCI, variable compression, direct injection, VVT and a variable geo turbo! My god that's a hell of a shopping list they've got there.

I imagine it cruises along at 11-12:1 running in hcci, getting crazy economy - then you plant your foot and it simultaneously drops the compression, switches to spark ignition and changes the turbo vanes to wallop some boost in there.. awesome

Thanks - did not think of wicks pedia..

I would think the cruise cr would be a lot higher . more like 15 to 1 or even 18 to 1 like a diesel..

Hope they put it in a A class to really show us what it can do.
