How to make a routemaster comply to euro IV emission standard?

Is there engine that can fit into the beautiful routemaster AND satisfy the EU IV emission standard?

The law is strict in my country. Thanks a lot!

Talk to Cummins. You won't just need the engine, but the ecu as well. With no idea of what is currently in your bus I expect you will probably need a lot of other expensive modifications as well.

What country are you in? Most countries have an exemption for historic vehicles.

My bus number (if any): RML2532,GS67,MLL721,MLL738 and an RT.
