What do you mean by that?? :confused:

did you read the article?

"by the development of a new breed of fuel injectors by the Australian company Orbital"

 

"Two-strokes are of interest to the automotive industry due to their simplicity and high power-to-weight ratio - if only they weren't so dirty and fuel inefficient. Both these phenomena are caused by the two-stroke principle of using fresh, fuel-rich intake air to clean or scavenge the cylinder of exhaust gases. The tuned exhaust systems try and prevent much of this charge from escaping out of the cylinder with the exhaust gases, but a lot still does. With direct injected fuel, this is no longer a problem as air can be used to expel the exhaust gas, and the injectors only fire at the moment the exhaust ports have closed. Result is nice clean exhausts, free of unburned hydrocarbons, and un-polluted clean fresh charge waiting for the big bang of the next ignition pulse. Two-stroke heaven. "

 

"The fuel injection system will be linked into an engine management system that checks many of the factors that influence the amount of fuel to be injected, including air temperature, water temperature, exhaust gas temperature and airbox pressure"

 

"Another major contribution to the clean exhaust of the Due is the use of the gearbox oil to lubricate the main bearings, rather than relying on the fuel/oil mist of regular two-strokes. Cylinder and crankshaft lubrication is still performed by two-stroke oil, flowing down small galleries into the guts of the engine. There is a two liter oil tank partition to the fuel tank that will need very infrequent topping up"

 

"with a hydraulically-actuated dry clutch and 6-speed side-loading cassette gearbox that will come in handy if you want change your gearing for your favorite set of curves"

 

nothing against the RZ 500, but this thing is just so impressive, a 2 stroke that meets EPA standards and still hauls balls.
