Re: Engine design
The advantages of interfering engines is that you allow pistons to come
up very close to the valves thus getting more compression and thus higher
HP output from the same volume. However, you need to syncronize things so
the piston doesn't actually hit the valves.
When the timing belt brakes, the valves are left in the position that
they were prior to breakage, while the pistons continue to move through
the cylinder for a brief period of time. Bang! The piston hits and bends
This very expensive to fix...
This a very simplified explanation, but gives basic understanding.
