M136 Engine Technical Data
The
Mercedes M136 engine family was composed of two versions with production
beginning before the outbreak of the Second World War, temporarily ended
during the war, and then resumed after the war.
The M136 1.7 L (1,697 cc) motor was introduced in 1935 for the W136 sedan, model 170 V. It was enlarged in 1950 to 1.8 L (1,767 cc) and installed in the W136 170Va 170Vb 170S, W120 180, and W191 170S, remaining in production until 1955 when it was replaced by the 1.9-litre M121.
The M 136 is a water-cooled motor (thermostat without short circuit) with valves arranged standing in a row on the right side. The triple bearing crankshaft and connecting rods are forged from steel. The camshaft is driven by a double roller chain. The engine initially had a riser carburetor (Solex 30 BFLVS), and later in the models 170 S / Sb (W 191) and 180 (W 120) a downdraft carburetor (Solex 32 PBJ).
Prior to the war in 1939, the M136 powered the 170V selling over 75 000 units by 1942. Production tooling survived world war II bombing and by 1947 it was again Mercedes top-seller until production ended in 1953. The V stands for ‘vorn’ (‘front’) to differentiate it from the previous W28 170H – ‘heck’ meaning (‘rear’) indicating engine location.
The initial capacity was 1697 cm³ (bore 73.5 mm, stroke 100 mm), and in 1950 it was increased to 1767 cc (75 mm bore, stroke 100 mm), increasing power from 38 to 45 hp.
