ETK K Series question

Hi is there a way for an ETK K Series to catch fire on it's own after crashing (not using fire debug or anything else). I found that the ETK K Series is almost impossible to catch fire naturally. Is there a specific place that the engine must be hit in order for it to catch fire ?

 

it's a modern, direct injected, turbocharged engine. no carbs and not a lot of reason for the engine to catch fire. the fuel tank may, but the engine is very unlikely.
