The direct injection technology has been used for a few years now on snowmobiles and a select few outboard two stroke boat motors. Its actually quite slick.
Kind of off topic.......but Mazdas 16x wankel rotary (to me) is more like a two stroke motor than a fourstroke in the sense that it uses ports instead of valves. The efficiency increase seen on that motor if it ever gets released in a vehicle will have vast improvements over the current renesis rotary.
Another good example is BRP's two stroke snowmobiles. They can get up to 26+ mpg (pretty impressive) on the trail and the tuning potential is greatly increased when compared to carbs or efi. It also allows them to run a really lean oil mixture since no oil is injected into the combustion chamber, it is injected into the crankcase.
Just some food for thought.
