Few points have aroused such discussion among users and engineers as that of the desirable number of cylinders in an engine. A large part of the work of the author has been in the direction of attaining the same ends as those achieved by the multi-cylinder engine but by different means. He discusses the relations between torque at clutch and number of cylinders and multicylinder engines and uniform torque, the factors governing torque recoil, torque recoil as a function of car weight and engine balance.
His conclusion is that the multi-cylinder engine now so widely used exceeds the real requirements and obtains its smoothness of operation at the expense of more desirable qualities.
A reduction in car weight would in his opinion enable existing standards of performance to be maintained and even improved by the use of four cylinders for the heavier type, with all that this means in tremendous advantages to the automotive industry and to the user. In the near future the chassis will probably be designed to conform to the body work of the car, and there will be two types of chassis, one suitable for heavy closed and open bodies, and the other for bodies of the roadster type.
