diesel motors run because the fuel they use is a "combustable" fuel. the pressure exerted on the atomized fuel in the cylinder by the piston causes a rapid rinse in temperature causing the fuel to ignite but under such pressure it is more liken to a "detonation", driving the piston down and thus rotateing the crank. steam is atomized water built up to high pressure by the boiler where the steam is stored and fed to the pistons by valves and release valves to keep the 2-way piston in continuous motion. the water can not be built up in a piston and heated to steam fast enough to work, plus the loss of pressure on the piston would be so fast as it started to move that i would not have enough inertia to keep it moving.
