Diesel Technology

Diesel engines have been in commercial use for over a century and in fact, are the dominant source of power for commercial trucks, trains, ships, and stationary power sources. Because of this, diesel mechanics have long been a vital part of the economy and their importance continues to grow as the popularity of diesel engines increases.

From the small diesel engines used for portable generators to gigantic diesel power plants driving ocean-going freighters, diesel engines are a central part of the world’s transport and industrial infrastructure.

For this reason, a career as a diesel mechanic is an extremely attractive option for individuals seeking a well-compensated and dependable source of employment.
