Another interesting engine, oi a type which may usefully be compared with the other one described on this page, is the 105 lip., sixcylinder, sleeve-valve Daimler, an example of which is shown under going test. The Daimler Co., Ltd., is, of course, only using this for its heavy work, principally on tractors and the Daimler road trains.
This engine has both a bore and stroke of 150 mm., and its constructional features are similar to standard Silent-Knight practice. There are two sleeves, as usual, to each cylinder, only in this case the sleeves are driven from two eccentric shafts, which are placed symmetrically on each side of the engine, and are actuated by two raw hide pinions of large size. One of these eccentric shafts drives the outer sleeves, whilst the other one operates the inner ones.
Special features of this design are the ample bearing surfaces which are arranged for throughout the unit, and these, in conjunction with special oil-pumping arrangements, should insure efficient lubrication. The illustration in this instance shows the engine on a composite brake of the rope and drum type. That of the Commercar engine shows a Froude water dynamometer in operation: the two methods form an interesting comparison. We are happy to have been able to record the production of these two interesting machines at the same time.
