OH.... I meant NO way...

And regaring the 2nd question- the deciding factor on the design of engine parts are the peak firing pressures. (The pressures after combustion) Increse in injection duration does not do much to increase that. (I've to check this up.. but if I'm wrong I'll post here). But turbo charging and cylinder head shaving does. So that is why you see more failures there and not much mechanical failures with petes.

The issues with the higher power- in my opinion- is higher load for the cooling system, which always has much higher safaty factors.

And JK- the MS thesis is on gasoline Engines- Using the spark plug as a sensor to characterise various in cylinder parameters viz, Air fuel ratio, pressures, Knock etc. I miss diesel now.
