The boiler maintenance is alsoreduced in that it is possible to reduce the boiler pressure if theconstruction of the cylinders is such that their diameter may beincreased. By increasing the size of the cylinders withoutdecreasing the boiler pressure the engine is given a greater start-ing power and the increased boiler capacity will more than takecare of the demands of the larger cvlinders for steam.
