Complicated New Work Trucks Are Testing Many Mechanics' Skill
Many people familiar with the dramatic changes taking place in work trucks powered by diesel engines are groaning, grumbling and complaining about what those changes are doing to their businesses. Federal air-quality regulations for new highway trucks, the latest round in effect since January, are driving engine manufacturers to add on complex emissions reduction and electrical systems that also must protect power, torque and fuel economy. Whats more, petroleum companies are reformulating lubricants to match the new engines needs and truck manufacturers, dealers and body fitters also are working to offset the added repair and component costs of these vehicles with ancillary features to make the complete package worthwhile for construction end-users.
The added costs are clear, but some of the benefits to the owners have yet to be seen. And the changes coming all at once seem like enough chaos to make a construction mechanic blow a head gasket.
