Detroit Diesel

The history of this family of diesel engines began even before World War II, when the 71-series 6-cylinder in-line diesel engine was introduced as the
flagship product of the Detroit General Motors diesel engine division. Then, in 1957, a wider version appeared.

 Interestingly, the 71 series designation refers to the cubic capacity of one cylinder, measured in cubic inches. It was
exactly 70.93 cubic inches or 1162.4 cubic centimeters. Knowing the number of cylinders and their power, it is very easy to calculate the total cylinder capacity of the entire engine. For
example, 8V71 had 8 times 1152.4 cubic meters. cm (about 71 cc) or 9296 cc Cm (9.29 liters).

In-line engines had one, two, four or six cylinders and were marked 1-71, 2-71, 4-71, 6-71, respectively. The blade blocks had 6, 8, 12, 16 or 24 cylinders and were
designated as 6V71, 8V71, 12V71, 16V71 and 24V71. In addition, the two largest units used many smaller engine heads to maintain reasonable sizes and weights. Therefore, in a 16-cylinder engine,
four 4-71 engine heads were used, and in a 24-cylinder engine there were up to four 6-71 engine heads. This solution also significantly reduced construction and maintenance costs, as many parts
were common for small engines.

 An interesting feature of the row units was their symmetry, which meant that individual parts of the equipment could be
installed on both sides of the engine, depending on the application. Many models can also work clockwise or counterclockwise. Engines operating “left” were commonly used in boats and
buses.

 All 71 Series engines use the so-called Blower Roots in the rinse cycle.

 They are installed on the outside of the air pump with pistons that prevent rotation and block, for pumping air at low
pressure into the cylinders, through the core channels in the block and openings in the cylinder walls.

Engines had two or four valves per cylinder and a fuel injection unit (one injector per cylinder). They were available both in naturally aspirated versions
(designation N) and turbocharged (T) and additionally equipped with an intercooler (TA). Trucks and buses also featured Jake’s famous brake (described here on DAF 95.500).

Series 71 vane engines reach 10 to 1800 hp In trucks, the most common were 6-, 8- or 12-cylinder units. The smallest of them, in their characteristic work, were
called “Screaming Jimmy” or “Screaming Jimmy” (Jimmy as short for General Motors). They reached 238 or 304 hp. in a turbocharged version. The V8 variant developed a power of 318 or 384 hp,
and the model with 12 cylinders was nicknamed “Buzzin Dozen”, and in the case of trucks, it developed a power of 450 to 550 hp.

There were more powerful options for the 12-cylinder version, reaching up to 900 hp. However, they were used in other vehicles than trucks or as industrial engines.
Interestingly, each of these units reached maximum power after it exceeded the limit of 2000 rpm.

Series 71 was very popular in the United States. These engines powered almost everything. In the 1960s and 1970s, almost every intercity bus was equipped with
such Detroit Diesel engines with 6 or 8 cylinders. The characteristic sound of six-cylinder in-line vehicles was also often mentioned by soldiers involved in World War II. Indisputable
advantages, with simplicity at the forefront, made Detroit in various configurations a mass for infantry and tanks.

What did the civil engineers appreciate, what did the builders of military vehicles appreciate. There were many cars on American construction sites equipped with 71
series two-stroke diesel engines. Pollution of the environment, obviously, did not impress the engines — it was only important that the engine had oil and fuel.

 After writing this article, I came across a lot of memories of people who used the 71 series engines. Almost everyone
emphasized the same features. They had a characteristic sound of work, as well as a high level of noise. Low repair costs were significant — for example, replacing a full piston cost no more than
$ 70, and an injector up to $ 20. Also mentioned were low power consumption in a lower rotation range and … problems with compaction of earlier versions. Apparently, this problem was so big
that in the 1960s, dark traces of motor oil could be seen on whole concrete sections of motorways (improvement was achieved through the use of o-rings). At the same time, this is evidence of the
popular Detroit Diesel 71 series engines.

Detroit Diesel is an American manufacturer of automotive, stationary and industrial diesel engines, bridges and gearboxes. Since its founding in 1938, Detroit Diesel has produced more than 5 million units, of which at least 1 million is still in operation.

The company was born as a division of General Motors, focused exclusively on the development of diesel equipment. In 1965, Detroit Diesel went into “free swimming”, and in 1970 entered a new stage of development, merging with the developer of gas turbines Allison Division. In 1987, the company revolutionized the market by launching a series of power units with electronic control system (DDEC). The innovation allowed to reduce the consumption of oil and fuel, and automate the work of engines.

Detroit Diesel works closely with the German developer Bosch – together with it the company has released a series of engines with the technology of supply and injection of common rail fuel. The brand also has its own novelties: a water pump with electronic control, generators with water cooling (one hinged, the other – built into the cylinder block).

Today, Detroit Diesel is part of the Daimler AG concern and is focused on the production of diesel units for heavy trucks, buses, construction equipment. Some series (for example, S50, S149) are no longer produced, but the company continues their service. The most popular among the manufacturers of equipment are the following product lines:

S60 – started in 1987, the power range of 400-600 hp, the working volume of 12700-14000 cm³.
S40E – production began in 1991th. The series immediately received electronic control and is characterized by economy and low level of vibration. The maximum power is 175-250 hp, the working volume is 7600 cm³.
S4000 – the most powerful series, developed in conjunction with specialists MTU. The power range is 951-5846 hp.

Detroit Diesel closely cooperates with manufacturers of Volvo Penta, Daimler Chrysler, Koler, and invests huge funds in researching new technologies. For this purpose, the company has about 200 dynamometer stands in Europe and the USA. Priority of the brand has not changed since 2000 – these are engines for heavy trucks. In this segment, Detroit Diesel achieved phenomenal success.
