With 2 stroke saws the mix needs to travel through bottom end first, unlike a 4 stroke car. So I am guessing direct injection for that would be a injector in the crankcase?
I try to explain it:
On the TS 500i: The injection valve is bolted onto the cranckcase. On the MS 500i it is a little bit different.
On the MS 500i:
First, there is the air filter sitting on the air filter base. After the air filter base comes the throttle shutter. If you push the throttle trigger, the throttle shutter is opened and air (more air) can flow through it. This throttle shutter is based onto the tank housing and after that there comes the air intake manifold. That manifold goes through the air guide shroud on to the injection housing. The fuel injector is bolted onto this injection housing and injects the fuel into it. This injection housing is bolted on the cylinder intake. The incoming air into the injection housing takes the injected fuel and goes together with the fuel into the cranckcase.
