comfort of its suspension, and for
its powerful and progressive 4-wheel braking system.
It readily lends itself to the fitting of any type of
body from a torpedo to a landaulet, and the luxurious
enclosed drive body... See also the original

The engine was slightly under 2 litres (1,995 cc), with 4
cylinders in a single block of cast iron with inserted head housing three
supports for the camshaft controlling the interchangeable valves by rocker
arms. The engine was silenced by equalisers on the camshaft, controlled by a
vertical shaft with helical gears, also controlling the water pump, magnet,
cooling fan and dynamo. The oil pump was fitted to the gear shaft and provided
oil under pressure. A high voltage magnet was used for ignition, with manual
control on the steering wheel.
The carburettor was automatic, with pedal or manual
control. Cooling was by water pump with radiator fan. The clutch was dry and
had only one disc, with a series of springs on the disc thrust device.
The four-speed gearbox had a trains balladeurs reverse gear.
A shaft transmission was used, with single universal joint and rear torque with
spiral Grearson teeth. The back end was in stamped steel. Braking was on all
four wheels, with the handbrake applied to the rear wheels or the gearbox
pulley. The frame was in C type 3 mm steel profile with rigid axis suspension
with half-elliptic spring.

Grand
Prix 8 cilindri compressore
|
In mid-May 1924, Diatto and Maserati brothers,
constructed a Grand Prix racing car with a linear 8-cylinder 2-litre (1,995 cc) engine with 65.5 mm bore and
74 mm stroke. Initially, elektron pistons were used, by they were immediately
replaced with aluminium pistons.
The cylinder head was made of aluminium, with inserted
steel caps. The cylinder block, in aluminium, had screwed-in steel liners. The
connecting rods were tubular, with two overhead camshafts controlled by
cylindrical gears. The first tests were carried out with atmospheric feed and
two or four bronze Zenith carburettors, of 16 diameter. The engine weighed 156
kg (about 343 lb.). The engine was fitted to a 20 S Type frame and won the
Parma-Poggio di Berceto with Alfieri Maserati. Subsequently a Roots compressor
was fitted with two pressurized Memini carburettors downstream of the
compressor.
A special mix of fuel, with Avio petrol and a small quantity of
benzol, was used to deliver close to 150 HP.
