hello:
i want to design a circuit using microcontroller for watching a disel engine parameters as (temperature,presure and its generator) .
what is the better choiseIC or AVR for working near an engine

Go to the Atmel website. Theu have a whole series of AVR chips, specifically for automorive applications. I never read anything on them, as have no need at this time.
I just started last December, done a few abusive things in the learning process, and yet to destroy my first MCU. AVR chips are pretty tough.
Like it's stated above, you need to protect any circuit placed in the engine compartment from heat, elements, and vibration. All the components, not just the MCU have an operating temperature range.
For heat, get a MCU with an extended temperature range. The PIC16F628 extended temperature range device works up to 125C whereas the industrial temp range ones only are spec'd to 85C. The support components also have to be spec'd to the max temp you'll expect as it is always the weakest link that fails.
