Mercedes-Benz 240 D 3.0 W115 1974-1976 80 cv 148 kmh 0-100 kmh 19,9 s
http://Carwp.blogspot.com.br (from Daimler Press Release) 40 years ago: The
240 D 3.0 was the first series-production car with a five-cylinder engine.
-Most powerful and fastest diesel car of its day
-Innovative starting technology: a turn of the ignition key was all it took
-"Stroke/8" model series set the standards in the premium middle-class
Stuttgart. -- 59 kW (80 hp) signified a quantum leap in 1974: The
five-cylinder diesel engine on board the Mercedes-Benz 240 D 3.0 produced
such an output, making the model series 115, commonly known as the
"Stroke/8", the torquiest and fastest diesel-powered passenger car in the
world. The diesel engine combined strong driving power with impressive
economy. At the same time, the 240 D 3.0 was the first series-production
car with a five-cylinder engine.
Five-cylinder diesel engines were not a totally new phenomenon 40 years ago
- they had already proven successful in trucks and as stationary devices.
Their use in a passenger car placed Mercedes-Benz in the headlines and
assured the company of a pioneering role in the field of engine technology,
however. The new engine accelerated the 240 D 3.0 from 0 to 100 km/h in
19.9 seconds, with a top speed of 148 km/h (automatic: 20.8 seconds, 143
km/h). This performance made the 240 D 3.0 the undisputed leader in the
field of diesel-powered cars at the time of its press launch. "With its
refined character, smooth running and economy (10.8 litres of diesel per
100 kilometres), the latest diesel-powered vehicle from Mercedes will
appeal to a new and broad range of customers," predicted the press
announcement, claiming: "With the 240 D 3.0, driving a diesel has become
even more attractive." From a present-day perspective, the car undoubtedly
paved the way for the continuing success of the company's diesel cars.
One more cylinder for added output
Mercedes-Benz developed the OM 617 engine in response to the fact that the
four-cylinder diesel engines used in passenger cars to date had reached
their limits in terms of output. The need for more cubic capacity from
which to coax more hp came up against the limited space available in the
engine compartment. Tests conducted by Mercedes-Benz with a six-cylinder
engine revealed it to be too long, too heavy, and too expensive. Five
cylinders appeared to represent the ideal compromise.
The engineers developed the five-cylinder in-line engine OM 617 for use in
series-production cars on the basis of a 2.4-litre OM 616 engine. The
latter's proven characteristics were retained, but the five-cylinder engine
was provided with a new Bosch injection pump which was connected via oil
ducts to the engine's oil circuit and was thus maintenance-free. A
mechanical governor replaced the pneumatic governor which was customary for
the smaller diesel engines. This benefited driving comfort -- the 240 D 3.0
with manual transmission revealed virtually no load alteration effects, and
with automatic transmission gear-changing was substantially smoother in the
partial load range.
The five-cylinder in-line engine's increased cubic capacity of 3,005 cc
produced an output of 59 kW (80 hp) at 2,400 rpm. The press reporters also
welcomed the additional output: "This added power provides a very pleasant
Boost in practice. [...] To put it
bluntly: The 240 D 3.0 is the first diesel car that can keep the pace in
fast traffic without hindering other vehicles," wrote "Auto Zeitung". And
"auto motor und sport" commented: "Despite the higher gearing, the 15 hp
more in comparison to the 240 D provide the 3.0 with a pace that will also
be to the liking of drivers who are not sworn diesel fans."
Innovative starting technology: a turn of the ignition key was all it took
Operation of the car also boasted innovative features: the use of a
pneumatic stopping mechanism rather than the mechanical variant of the
2.4-litre engine enabled the new engine to be switched off with the
ignition key. The engine of the 240 D 3.0 was also started up by turning
the key, as opposed to the previous practice of pulling a lever: when the
driver turned the ignition key, the pre-heating process was initiated and
an indicator lamp went on. After a short time, the indicator lamp duly went
off again, and the engine could be started up in the normal manner with the
key. Very much the norm today, this mode of operation was valued as a
convenient innovation in 1974, after which it successively became
established for all diesel cars from Mercedes-Benz and other makes.
Mercedes-Benz also used the five-cylinder diesel engine in other vehicles,
such as light-duty vans, and from 1978 in the S-Class 300 SD (model series
116), which was intended for export to the USA; the turbocharged engine in the S-Class had an output
of 82 kW (111 hp) at 4,200 rpm.

world's fastest diesel mercedes w123 300d
w123 mercedes custom fitted with Supercharger and turbo charger with Intercooler air to air and mobil oil
cooler toooo and look at the donuts of this beauty,,,
for the details on hwo this engine was modded go to
here u can see the pics how he modded the car and hwo he installed the
superchanger turboIntercooler clutch plate pressure plate
Exhaust piping NOS and mobil oil
so for those of you who were thinking it is my benz ,,,nopes... it is
mr.valtonen car he is from finland ,, and finland is pretty famous with
w123 modifications there they modify MYNA pump with wider plunger and set
them to deliver more diesel then stock ones..
enjoy the clip and i hope people would love to see the pics too

Pressure-testing a Mercedes-Benz injector straight out of the car with no
modifications so far. Looks to be popping at about 1550psi, but doesn't
seem to hold pressure as you can see at the start and end.
For reference, what sort of efficiency are we looking at on this particular

A rainy day with the Benz
Song: Juan Luchini - Love remix
From Cape Town, South Africa.
A rainy day with the Benz (a.k.a Mila) was not suppose to be a rainy day at
all. The weather took a turn for the worst and we decided to continue. It
didn't turn out too bad I think. Hope you can dig it.
