Mr. de Glehnbelieves that for a given total weight a four-cylinder com-pound may be made 15 or 20 per cent, more powerful than asimple engine. He finds that the work of the engine isbetter distributed over the working parts and that with morewearing surfaces there is less wear than with a two-cylinderengine, notwithstanding the increased mechanical complica-tion. He finds that the repairs are less than with simple en-gines. The four-cylinder compounds are balanced, which hasan important bearing upon the cost of repairs, because theengines do not shake themselves to pieces. That they haveremarkable accelerating power is illustrated in the figuresquoted from Mr. Rous-Martens records. shown in the acompanying engravin
