In Depth Look At The Detroit Diesel Series 60 14L Engine: Overview And Part Options

You probably recognize the name: Detroit Diesel. Or, Detroit as it's known now. They've built some of the most popular diesel engines.

Detroit Diesel Series 60 EngineBeginning in 1938, the manufacturer was a part of GM, but, in 2000, it was sold to DaimlerChrysler AG. 

Its first engine was the two-cycle Series 71, which found its way into tanks and other equipment, particularly with the onset of WWII.

Since then, Detroit has manufactured a lot of very popular diesel engines, including the Series 60 engines. This post is taking a closer look at one of those Series 60 engines: the 14L.

Overview of the Detroit Diesel Series 60

Detroit Diesel is known for releasing 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. 

What Makes the Series 60 Different?

The first engine in the Series 60 line was produced in 1987. It was a more fuel efficient choice than what was commonly available for heavy-duty at the time. 

Despite Detroit having since discontinued 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. 

These systems 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. It's not just bigger than the 11.1L and the 12.7L. Detroit made a few changes to its design. 

It has a larger crankshaft and increased horsepower, for example, which also led to higher fuel consumption. 

The 14L completely replaced the 12.7L when the smaller engine was discontinued in 2007.

Series 60 14L Application Uses

Like all Series 60 engines, the 14L features complete electronic controls, using 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.

Changes in the 14L Diesel Engine

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. 

These modifications included changes to the ECM. More specifically, Detroit moved to a multiple ECU design. 

The 2007 changes to the engine in particular led to cleaner emissions in an effort to comply with the harsher EPA rules regarding NOx.

What Replaced the 14L Engine?

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. Its durability and power help keeps its place in the diesel engine history.
