DIESEL ENGINES - TROUBLESHOOTING AND REPAIR

Paul Dempsey

There are several areas that have changed drastically during the last few years with diesel engines and will greatly affect the near future of diesel engine technologies. The highway trucking industry was the first to require these changes to meet federal EPA emissions guidelines for diesel engines back in the late 1980s. In the mid-1990s these same guidelines were required of the off-highway heavy equipment industry. Now even areas not affected in the past such as the marine, petroleum, and agricultural industries have come under these new requirements. They will change these industries in the same way they have previously changed the trucking and heavy equipment industries. During the last 20 years only certain engine horsepower sizes or industries have come under these federal guidelines. However, the 2007, 2010, and 2012 emissions guidelines will cover and affect all horsepower sizes and industries. Additionally, in most areas the current

technologies to meet the 2007 guidelines will not completely meet the 2010 and 2012 requirements without additional technological changes or improvements. These technological changes are inevitable and future technician training needs will be a reality. This is where diesel engine course books like Troubleshooting and Repairing Diesel Engines can help the technician stay current with these changing technologies. To show how rapidly these changes have taken place, information of some past and current examples of those areas affected are mentioned...
