Saab two-stroke
Template:Short description The Saab two-stroke was a two-stroke cycle, inline, two cylinder, and later three cylinder engine manufactured by Swedish automotive manufacturer Saab that was based on a design by German manufacturer DKW.
Two-cylinder
The first version was a Template:Cvt displacement straight-twin that was transversely mounted in the 1950–1956 Saab 92. It produced Template:Cvt and the car had a top speed of Template:Cvt. For the 1954 model year the engine received a Solex 32BI carburetor and an improved ignition coil, which raised engine output to Template:Cvt. It had some modern features not found in other cars of its time period, such as one ignition coil per cylinder.
Three-cylinder
The second type of Saab two stroke engine was a longitudinally placed inline-three cylinder of Template:Cvt and initially Template:Cvt. It was used in the Saabs 93, 94 (Sonett I, with an engine tuned to Template:Cvt), Saab Sonett II, 95, 96, Saab Granturismo, the Saab Formula Junior and the Saab Quantum. The engine had a combined belt driven DC dynamo and a coolant water pump.
The Saab Formula Junior used a 'bored-out' horizontally mounted Template:Cvt version which utilized two dual Solex carburettors developing some Template:Cvt. One of these carburettors was divided in half, thus providing three chokes, one for each cylinder.
The Template:Cvt engine used in the 1966 Saab 96 used pre-mix oil and appeared with a three-throat Solex carburetor in which the center carburetor handled start, idle, and low speed functions, increasing the power to Template:Cvt. The same carburetor had been used in the Saab 96 Monte Carlo and Sport models. The use of a common throttle shaft minimized carburetor synchronization problems.
The 1958-59 Sports version of the 93B had Template:Cvt in base version and Template:Cvt in the super version. This model had triple carburetors and a motor oil injection system, rather than oil pre-mixed with the petrol.
From 1959 the displacement was raised to Template:Cvt with Template:Cvt. For model year 1966, the 'standard' 3-cylinder two-stroke engine had three individual carburetors. From model year 1967 Saab began replacing their 3-cylinder with the Ford Taunus V4 engine.
A special version known as the 'Shrike' was built for the United States 1967 and 1968 model years. It was sleeved down to Template:Cvt to avoid US emission regulations which exempted engines under Template:Convert.[1]
Saab also made some experimental V6 engines by mounting two three-cylinder two-stroke engines together at an angle. One of these experiments had carburetors mounted outside of the V, while another had a more conventional design with a carburetor in between the two blocks.
Production
Initially all two-stroke engines were built at the Saab Trollhättan plant, however in 1953 engines and gearbox production[2] was moved to an old washing machine factory in Gothenburg.[3]
When Saab discontinued production of the two stroke engine and replaced it with a four stroke V4 engine built by Ford in Germany, the plant in Gothenburg never again produced engines; the production capacity was needed for the increased demand of gearboxes due to the introduction of the Saab 99 a few years later.
