Here’s something to keep that’ll excite the 2 stroke fans

Patents by Honda have just been published showing the factory is working on an all new design for a fuel injected two-stroke engine which will release less emissions, easier to maintain and less expensive than some of the other players in the game, at the same time delivering the power the other modern 2 stoke bikes are producing.

On the drawing above, tagged with the numbers 71, 70 and 74 can be seen a fuel injection system. The unit is mounted low-down in the cylinder and angled upwards – this is so that the fuel ‘cone’ that is sprayed into the chamber as an atomised mist is launched over the second scavenger port in the cylinder.

Because the fuel is sprayed so finely and can be directed into the chamber so accurately, plus be timed so expertly, the burn is very clean and efficient meaning that emissions are very low indeed. The fuel is used as a cooling element inside the cylinder to further increase overall engine efficiency.

Compared to the old two-stroke feed technology this is light-years ahead and clearly Honda is confident that is can build a modern, light and powerful two-stroke motor that will be compliant with various legislation around the world.
