In one engine, which hasbeen in daily use for a year and a half, the slide has not beenrefaced or scraped up during that time. The soot and oil vaporappear to act as an excellent lubricant. The oil is pumped into the chamber by a diminutive force-pump worked by the is on,^the right-hand side of the cylinder. * The engine is on the three-cycle system, the same as theGriffin and Beck gas engines. The great advantage of thissystemfor oil engines is, that as the exhaust is completelyclearedaway from the cylinder the charge of vapor and oil ismore readily ^The governor acts in a twofold manner,firstby stoppingthe supply^of,oil]^to the vaporizing chamber,. and by preventing the valve connecting the cyliinji-i auvi vapor-izing chamber from opening, so that an explosion is cylinder is water-jacketed, the water circulating as in gasengines. No oil is required in the cylinder ; a small quantityof the vapor condenses at each stroke and acts as a slide requires a small quantity of oil. The \ H.
