Guaranteed not to let water into the bores.

Edit: indicative pricing.... £3000

Have been following this with interest, it's technically pretty incredible.

Though I'll stick with the time honoured method of a weber throwing some fuel and air in the general direction of the ports. Seems more fitting.

I was dreaming about doing the same thing a while ago - seeing it in the flesh is pretty good

So how is this going to help `charge robbing' on a 5 port head? You will just have air charge robbing, instead of air/fuel mixture robbing.
2 cylinders will still get better volumetric efficiency (cylinder filling) than the other two do. Yes? No? Maybe?

IMO they should have done it with a 7 or 8 port head.

they're talking about the charge robbing problem you get when trying to do multipoint sequential injection

Even with the charge robbing that will happen with siamesed port you could now go to extremes and build an engine that takes that into account since you don't have to worry about what the fuel is doing.
I see the possibility of using different compression ratios for different cylinders.

maybe i should have used electronics for my DI A-series engine instead of a mechanical diesel pump.
but Mitsubishi was the only one with such a system back then and parts were expensive

very good video from Bosch about direct injection... https://www.youtube.com/watch?v=LjJSbHxIvnM

I'm not keen on how they make out that they invented port scavenging though!

I'm always glad to see people still putting time and effort into the old A-series engine!

very basic set up. i read some articles about direct injected plane engines and the story about first DI car engines and came up with this quite stupit idea.
belt driven injection pump from a 1.7l Opel diesel engine, cheap as hell over here, fitted to a 998ccm engine. some, modified for lower pressure, DI diesel injectors.
had some problems. hard to start when hot, if running it won't run very well, had some leakage problems.
sure if you invenst more time and money it could work much better. maybe using a non-diesel pump, purpose designed injectors, and so on.
i lost interest as cost start to increase to iron out the faults. and as the price for "regular" EFI dropped i went this route.
