Smith} CHASSIS ENGINE. <s>X7771</s> X7770 X7090 This is undoubtedly distinctly more powerful and our acceleration, hill climbing, and maximum speed; should satisfy the most enthusiastic motorist, and we ought to get back some of our old friends who desire plenty of power. It makes one more satisfied with our old carburetter, whose other virtues we should like to retain. Two engine improvements appear in 19-EX. engine: (A) In spite of a cold engine(and poor slow running before warming up) the car went away extremely well on opening the throttle, (water cold, water heated throttle;) we had hoped for this with the altered induction system. (B) For no apparent reason this engine does not bang in the silencer, cutout open, and at all speeds, governor closing throttle. If this unexpected improvement is supported by other specimens it will be a great advance. A collection of such items might be useful Sales matter. It has occurred to me that we might use up showroom parts of Phantom, and replace by aero engine and 20HP. R.{Sir Henry Royce} | ||
