This is also why nearly all diesel engines are interference engines—by their nature diesels are very high compression engines. The benefits of high compression are so good that many engine designers decide it’s worth the risk to have an interference design.
Are diesel engines non interference?

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.15 мая 2018 г.
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.
What are non interference engines?
An interference engine is a type of 4-stroke internal combustion piston engine in which one or more valves in the fully open position extends into any area through which the piston may travel. By contrast, in a non-interference engine, the piston does not travel into any area into which the valves open.
Do I have a non interference engine?
The difference between an interference and non-interference engine is whether there is a gap between the valve that is fully open and the piston that is in the top position. If there is a gap, the engine is called a non-interference engine. If there is no gap, it is an interference engine.
Will a broken timing belt destroy my engine?
If a timing belt breaks, the engine will no longer work. … This may result in a heavy damage to the engine with broken or bent valves, damaged pistons and, possibly, destroyed cylinder head and block.
Are Toyota engines interference engines?

Why do interference engines exist?
It broke while the engine was running, so the pistons are in motion. Because the timing chain/belt is broken, the valves aren’t moving, which means some of them are stuck in the open position. If the piston travels far enough in the cylinder to actually hit the open valves, that’s an interference engine.
Does a VW TDI have a timing belt?
