What is it like being a diesel mechanic?

Mechanic is an interesting trade and skill to have. Especially how Diesel engine works and where we use it. The challenge we have today is less reliance of fuels like petrol and diesel. Diesel technology is best used in heavy transport and shipping companies. The future of diesel mechanic is to make eco-friendly engines that does not pollute the environment and become more cost efficient. I personally have studied the diesel engine for motor vehicles and it is interesting.
