A Look at Detroit Diesel Series 60 14L
Detroit Diesel, or just Detroit as it's more commonly known now, is one of the best known names in diesel engines. Beginning in 1938, it used to be part of GM, before being sold to DaimlerChrysler AG in 2000. Its first engine was the two-cycle Series 71, which found its way into tanks and other equipment, particularly with the onset of WWII.
As you may know, Detroit Diesel often releases its engines in series (except for the DD line, of course). One of the more popular series is the Series 60, which includes three different engine applications, a 11.1L, a 12.7L, and a 14L. The first engine in the Series 60 line was produced in 1987 as a more fuel efficient choice than what was commonly available for heavy-duty at the time. Despite Detroit discontinuing production of the Series 60, many engines from this line are still around. In fact, a large number of city buses use these engines, especially the smaller two versions.
Series 60 engines are also Detroit Diesel's first engine to be fully electronically controlled. Their DDEC (Detroit Diesel Electronic Control) systems helped revolutionize engine controls and gave many fleet and owner-operators greater control over the management of their engines. It included engine diagnostics, as well as warning lights for the driver. The DDEC system has gone through several versions throughout the years, with changes including horsepower rating and different ECM voltages.
The later version of the Series 60 engine, the 14L, is the focus of this blog post. More than just being larger, it's a fair bit different from the 11.1L and 12.7L. It has a larger crankshaft and increased horsepower, which also led to higher fuel consumption. The 14L completely replaced the 12.7L when the smaller engine was discontinued in 2007.
Like all Series 60 engines, the 14L features complete electronic controls in the form of the later DDEC versions. While this version of the Series 60 may not have been as popular with buses as its smaller counterparts, it did dominate the Freightliner over-the-road applications. Freightliner and Detroit even collaborated on some engine road testing.
With the 14L, engine displacement increased, leading to its increased horsepower. It was also more efficient, as it was modified several times to keep up with increased emission standards and regulations. This included changes to the ECM, particularly the move to a multiple ECM system. The 2007 changes to the engine in particular led to cleaner emissions in an effort to comply with the harsher EPA rules regarding NOx.
In 2011, the Series 60 engines were phased out, and this included the 14L. They have been replaced in production with the well-known DD line, although Series 60 as an engine line remains extremely popular. It's durability and power help keeps its place in the diesel engine history.
