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.
