Internal combustion engine yes, as an external combustion engines sounds more like of an explosion engine in progress!
I was brought up motors were electric. But American will call there gasoline engine under the hood not the bonnet as motor!
Hydraulic motor is an odd one but still is hydraulic usual driven by a hydraulic pump. Why have the two in the same system! I worked for over twenty years on this system driving a large pinion and gear 20 foot diameter turn table via a two speed gearbox. The reason given gave a greater toque range from zero to 25 rpm almost at instant speed. Then used as a brake to stop rotation movement by reversing the hydraulic fluid in the pump. Stop a five ton load in one second with out any friction brakes been used. Course azimuth movement within in two degrees of the compass followed by fine azimuth movement of 0.5 degree accuracy of one degree. All within two half second. Running 24 hours 7 days a week. All Electronic controlled to.
Very tricky to set up to run smoothly but when running right poetry in motion.
I would of thought the azimuth pod propeller on today ships used a electric motor to drive the propeller blades and a similar hydraulic system to turn the pod clock or anti clock wise.
Steam is generated by boilers were the high pressure is used in the high pressure cylinder first then the exhausted steam still with heat and pressure is recycle into the next cylinder intermediate, then recycle again in to the lower pressure cylinder and final into a condenser.
in a triple expansion engine the exhausted steam recycled drops in temperature and pressure coursing the steam to expand in volume. Hence the three different diameter cylinder bores. High pressure cylinder 54" diameter. Intermediate cylinder 84" diameter and lower cylinder 97" diameter times twice.
You can see a fine sample of the worlds largest working triple-expansion been steamed up next March 16-17 followed by another six times this year, at Kempton Steam Museum south east of London near Heathrow airport. The engine is 800 tons as against Titanic 1000 tons. But still give you a good impression how big this engines were. A fine sample the workings of a steam turbine can be seen to without steam. High pressure steam turbines also recycle there exhausted steam to.
