Are interference engines better?
In comparison to non-interference engines, interference engines “breathe” better because the valves can open earlier, close later and open wider. Interference engines can also achieve higher compression ratios. These designs extract more power, use less fuel and generate fewer emissions.
What happens if a timing belt breaks on a non-interference engine?
If the timing belt snaps, they run into each other, causing bent valves (most common), cylinder head or camshaft damage, and possibly piston and cylinder wall damage. … In a non-interference engine, the pistons and valves don’t occupy the same space, so if the timing belt snaps, no valve or cylinder damage occurs.
