Spark plugs/injectors

[Gary Derian]

The Mercedes direct injection engines injected onto the combustion chamber
during the intake stroke.  This was so there would be sufficient time to
properly mix the air and fuel.  They were definitly not stratified charge.
The injector timing was set to end at 60 degrees after top dead center.  The
injector duration changed with intake vacuum but since they were mechanical,
the duration remained constant in engine degrees as rpm changed.

-> There are already some direct petrol engines on the market!!!!
->
-> Mitsubishi was the first one! The have the GDI-Engine ready, it's
-> sold even here in Germany at least for 6 - 7 months now!

Mercedes built direct-injection automobile gasoline engines from the
1950s through the 1970s, and they weren't the first to do it.

Bosch timed/metered rig, what they call sequential nowadays.  Worked
just fine, too.  Of course, these were all mechanical rigs, not
electronic.
