Toyota Type A engine
The Type A engine was a straight-six engine produced from 1935 through 1947 by Toyota and is a copy of the 1933 Chevrolet Stovebolt 207 engine.
The Type B was a technically more advanced version of the Type A. There was an enlarged version of this, called the Type D, but it did not enter production.
The Type C was a straight-four engine derived from the Type A.
Many parts were interchangeable between the Type A, Type B and Type C engines (e.g. pistons, valves, rods). Many of the same parts were also interchangeable with the 1930s Chevrolet First generation Stovebolt engines, from which it was derived.
The Type E was a copy of a DKW engine.
The Type S was a straight-four engine that replaced the Type A, B and C in Toyota's passenger cars.
The Type A engine was Toyota's first production engine, being produced from 1935 through 1947.
This engine was a 3,389 cc (3.4 L; 206.8 cu in) pushrod, overhead valve, 6-cylinder, three bearing engine copied from the 1929–36 Chevrolet Gen-1 3 bearing Stovebolt L6 OHV engine. By virtue of a modified intake manifold it produced 62 PS (46 kW), while the Chevrolet engine produced 60 PS (44 kW). GM used a number of local Japanese suppliers for the smaller engine parts (e.g. carburettors) while the Osaka Assembly location was open until appropriated by the Imperial Japanese Government. Toyota was able to use the same suppliers for its cars. The parts were identical enough that pistons, rods, valves, etc. could be used in both the Chevrolet and Toyota engines interchangeably. There are several recorded instances of parts intended for one being used to repair the other.
