Die Daimler-Benz A. G. beweist in Hannover, daß das Bauprogramm von Mercedes-Benz-Dieselmotoren eine wesentliche Erweiterung erfahren hat. Der Hochleistungsmotor vom Typ MB 518 (20 Zylinder) mit einer Leistung von 2500 PS wurde wieder in die Produktion genommen; bisher gingen die Lieferungen ausnahmslos ins Ausland. Eine völlige Neukonstruktion stellt der 6-Zylinder-Motor des Typs MB 846 dar. Er ist für eine vielseitige Verwendbarkeit gedacht und wird sowohl in stehender als auch in liegender Ausführung gebaut. Besonders in in- und ausländischen Schiffahrtskreisen hat er als idealer Bootsmotor starkes Interesse gefunden. Die aus dem Pkw- und Lkw.-Bau bekannten Typen OM 636 und OM 312 wurden neu in das Gebiet der stationären Motoren, Einbau- und Bootsmotoren eingereiht. Schließlich wurde speziell für den Export in wirtschaftlich unentwickelte Länder der robuste 1-Zylinder-Motor vom Typ MB 821 geschaffen. Neben einer Reihe von Weiterentwicklungen sei noch erwähnt, daß die in Berlin hergestellte Motorengruppe der Typen M 202, M 203 und M 204 in wesentlichen Punkten ebenfalls verbessert wurde.

Daimler-Benz to Exhibit Cars For First Time in Ten Years

Center of Interest Will Be the Mercedes-Benz With Independent Four-Wheel Suspension

After an interruption of more than ten years, the Daimler-Benz Company will again be represented at the Salon in Paris.

The center of interest will be the new Mercedes-Benz passenger car, type 170 S. The main construction features of the 170 V were retained in the 170 S, particularly the very light but strong and X-shaped frame made of oval steel tubings, and the principle of independent suspension for all four wheels. (The present independent front-wheel suspension is a completely new development, based on the experiences gained through leng and difficult trials with Mercedes-Benz racing cars. The front wheels of the 170 S are attached to the frame by parallel “wishbones” and are sprung through frictionless coil springs which were introduced by ~ Mercedes-Benz in 1931. This was later copied by mearly all the large automobile firms of the world.

Shock Absorbers

~~ Movements of the front wheels are controlled by large telescopic shock absorbers situated inside ie) coil springs. The linkage of the front wheels makes a small movement in the horizontal direction possible, 50 that even strong frontal shocks are smoothly absorbed. The same pertains to lateral shocks as the entire system is suspended in rubber blocks. A torsion bar connecting both front wheels stabilizes the car against rolling while corner. The well-proven “swing axles” of the rear wheels were retained, but their performance was considerably improved. Springing is made softer and progressive by using a supplementary spring, thus maintaining equal springing quality regardless of the load of the car. Here, too, frictionless coil’ springs are used in combination with hydraulic telescopic shock absorbers. The differential housing is fixed elastically, so that as with the front wheels, natural shocks are hardly transmitted to the frame.

As a result of this new springing system, to the broader track and to the use of super cushion tires, the 170 S has road holding and springing characteristics which Mercedes-Benz officials say excel those of more expensive and larger cars. In its main parts the engine of the new Mercedes-Benz 170 S is the same as that of the 170 V; its output, however, has been increased while maintaining the same economy and durability. At 4,000 r.p.m. the brake horsepower is 52, which represents an increase of 37 per cent compared with the 38 HP of the 170 V. Cylinder-displacement, however, was only increased from 1,697 ccm to 1,767 com, i.e. by 4 per cent. The greater part of the increase in power must be a.tributed to the sysematic refinement of the engine itself; e.g, the substitution of the vertical carburetor by a downdraft carburetor of the most modern construction, new intake and exhaust manifolds, alterations of the valve area and of valve timing.

Increased Power

The 170 8S being only a little

heavier than the 170 V the increased power brings about an improvement of acceleration, hill climbing and maximum speed which is now 75 mp.h. Due to the carefully selected jets of the new down-draft carburetor, the driver has the choice of driving at a moderate mean speed and with maximum economy (30 miles per gallon), or of utilizing full engine power at

the cost of a slightly higher fuel]

consumption (25 miles per gal.).

All four forward gears of the]

smoothly functioning transmission

‘are silent and synchronized. Four-

‘wheel hydraulic brakes were im-

proved to fit the higher speeds

and were made more endurable by

enlargement of the brake lining

area by 38 per cent.

The 170 S body contours have

become smoother and more siream-

lined, sharp angles have been

evened out, but all extravagance

has been avoided. ;

The inside of the car has been

greatly improved with ample space

for comfort. Each front seat is.

two inches wider and the rear!

'bench-type seats are four inches;

wider. Both front seats, built in

(the form of comfortable easy!

chairs, can be adjusted individually:

while driving by a small and handy

lever. The horn is operated by the

Mercedes-Benz ring situated on the

steering wheel and which in the

new 170 S also serves as a switch

for the direction indicator: ome

Ineed not take a hand off the steer-

ling wheel. A ventilating system

free of drafts and an optional

heater make driving comfortable

in all weather and temperature

conditions.

The 170 S can be supplied as a

four-door sedan, seating four or

five people; also as a two-door convertible “B” for four or five pas-

sengers; and as a two-door conver-

tible “A” for two to three passen-

gers. The car has an all-steel body

of very light. but extremely sturdy

construction; this body is mounted

to the chassis by thick and soft]

rubber blocks, thus all disturbing]

noises and shocks are absorbed, =

Convertible ‘A’

~The convertible “A” on exhibition

ai the Paris show will satisfy the

most extravagant demands both in

style and luxurious equipment, and

it is proof of the fact that the

Daimler-Benz body manufacturing

plant has again to the dullest extent attained its former internationally recognized reputation. ~The new Mercedes-Benz passenger car with Diesel engine, type 170 D, also gained attention when it apoeared on tis market togedcher with the 170 -S.- In 1936, the Daim-

ler-Benz Company had already

started the production of Diesel-

engined passenger cars. Numerous

cars of the type 260 D with ‘a 2.6-

liter four-cylinder Diesel engine

are still in operation today, giving)

the fullest - satisfaction to their

owners,

Engineers of ‘the Daimler-Benz

Compary have created a new 1.7-

liter four-cylinder Diesel engine

which represents an outstanding

achievement with regard to eco-

nomical operation, output, reliabil-

ity, flexibility, quietness, and sim-

plicity of servicing,

~~ With a cylinder capacity "of 103.5

cu.in. and a compression ratio of

19 to 1, the engine develops 38 brake horsepower. The car runs

40 to 43 miles per Imperial gallon

of Diesels oil and uses 0.28 Imp.

pints of lubricating oil per 100 miles

(or 34 to 36 miles per U.S. gallon

and 0.34 U.S. pints per 100 le

respectively), eg. it is possible to

cover 350 miles. without. refueling.

Since Diesel oil is much cheap<r

than gasoline, the new Mercedes-

Benz Diesel passenger car 170 D

holds an uncontested wor.d ecor-

omy wrecord in its class, officials

said.

In the field of commercial vehicles the Daimler-Benz Company is building ambulances, three-ton trucks and the heavy 5-ton truck, omnibuses, and = spacial bodies. It is obvious that here, too, the sturdy and economical Diesel engine plays a conspicuous role.
