Increased reliability
Remember,t that this increase in risk has to be offset by the fact that diesel engines are inherently more reliable than petrol.
No spark plus to fail, no carb to ice up (although a throttle, but less change due to no evaporation taking place) less chance of overheating, lower change of fire, no explosive vapours when refueling......
If we are to make sweeping statements about these engines being 'unsafe' I think that it could easily be argued that traditional engines are also 'unsafe'
Any chance of a highly informed comment from Ghengis on this subject?
