This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1905 edition. Excerpt: ...will permit without dependence on such means when forming the cam face curves.. 107. Valve-setting and Inlet-cams.--Inlet-valves should not / open till exhaust-valves have closed or a back-fire may result by opening of the connection between exhaust-pipe and mixing chamber, especially with several cylinders on the same exhaust. Exhausts close on center or slightly after center, hence in the latter case inlets open still later. Inlet Opens. Engine. About 50 after centre, large slow-speed engines, 100-250 R.P.M. "30" " medium-or slow-speed small engines. "6" " small high-speed engines, 500-800 R.P.M. Suction should continue till after center has been passed, especially in high-speed engines where the gas has considerable inertia. Inlet Closes. Engine. About io0 for large slow-speed engines. "40 for medium or slow-speed small engines. ' 150 for small high-speed engines. To secure a retardation equal at both ends and still retain the form of the roller center-line curve the same in form as the piston velocity curve for constant admission velocity, it might seem at first glance feasible to retard the whole cam, as in Fig. 135, the full line showing the original position and the dotted line the retarded position. A glance will show that the valve-lifts will not now be proportional to the piston speed, but on the rise opening will be smaller, while on the fall larger, than before retardation at the same crank-angles. It is more.important that the end of the curve give full opening with a decrease in gas velocity, perhaps, than that the rise of the curve be exact. For this reason the result of the process, while not securing the result desired, is not exactly detrimental. By making, however, a circular crest mm' and...
