Stihl Ms500i & Ms462 - What’s the latest ?

[Bustergasket]

I have heard a few things WRT 500i, similar weight to 462 but more power, it looks like 462 is happening but not so much info on 500i, any ideas ?

They made a TS500i cut off saw years ago but the technology has not got as far as chainsaws yet it's still in development. Petrol tech is being phased out in favour of battery power so they are probably not pushing it as much.

For injection to offer real benefits it needs to be high pressure. Crankcase injection doesn’t offer much over a auto tune carb for example. It is however a very good marketing tool!

I would have thought it would do away with the inlet port duration being dictated by port timing . 

The reed valve engines I have played with have had much more torque due to this!

Thanks for that great info, pleased it looks like they are stihl working towards it !, good point re reed valves, i guess when they go injection it will save the cost of a carb and all the associated pn’s, albeit a fancy mtune one, i think reed and rotary valve 2 strokes behave very different to piston port units, and as spud says torque can be beneficial and they seem to be able to achieve higher rpm.
