About steam driven cars
Stem driven cars were the first cars ever built. The first steam cars were built early in the 1800ths, but these were very heavy and unpractical devices. Around 1900 the steam engines for cars, the boiler and other equipment had evolved som much that the steam car was a very practical vehicle.
The internal parts in a stem driven car consists of the engine, the boiler, the fuel tank, the water tank and equipment to controle the combustion process in the boiler.
In addition to the throttle that controles the steam output, there are also automatic throttles for feeding of water to the boiler and feeding of fuel so that the pressure in the boiler is allways high enough.
Advanced steam cars also have a condencer so that the water can be reused continually.
Advanced steam cars have small boilers that continually produce the steam used so that very little steam is stored. This construction improves security and holds the boiler at a low weight.
A steam car do not need a gearbox or a clutch, since the steam engine have a torque allready from a low turning frequency and operates smoothley at all turning speeds.
Steam cars were actually more practical to use and more powerful than internal combustion engine cars up to around 1925 and in many parts of the USA, steam cars were prefered a long time.
A stem engine with a size to be fit into a car where and still is more powerful than a combustion engine of the same size. A main reason for this is that a steam engine can be constructed for double action and thus be driven by steam pressure both above and belove the piston and because steam engines will get new steam to drive the piston at each cycle.
The problem with steam cars is a bad utilization of the fuel, a high weight that increases fuel consume and that it takes a fairly long time to start it. These are the main reasons why steam cars went out of fashion. The boiler, water tank and condencer are the parts that add weight.
Beacuse of the power an agility of steam engines, there are however still projects going on to construct new steam cars for commercial sale. If the problems of fuel econimics is solved, stem car might get into fashion once more. The problem of long time to start is however practically solved technically.

If Your Car Engine is Starved For Coolant, it Will "Seize Up", Another Way of Saying "I Quit"
By Ralph Hoffmann
Most of us know from watching the old Western
movies that the old steam locomotives had a big cylinder full of water; when it
started to boil and the pressure began to rise, the space above the water filled
with “steam”, which is really not accurate; it was really full of hot water
vapor. Actual steam is invisible. What we call steam is really hot water vapor.
The engine and coolant system is really a simple boiler
Car engines operate on the same principal as a locomotive steam engine boiler. The difference is that instead of heating the water (coolant) with firewood or coal, we heat it with the hot engine where ignition is taking place inside of the cylinders at 2,000oF.
Modern car engine coolant systems are operated at about 220o F; which is above the 212oF that causes water to boil at sea level
As the coolant temperate exceeds 212oF, it begins to turn to steam and the pressure rises.. That means empty areas or volumes above the coolant levels will be filled with pressurized “steam”. The hot engine continues to add heat to the coolant until the coolant reaches about 220oF. The water pump continually moves the coolant around the engine cylinder block until the coolant temperature reaches about 212oF
Now the radiator starts to function
A temperature sensitive value now opens in the radiator, allowing the hot coolant to be pumped into the radiator where the air being pushed out of the way by the moving car will hopefully be enough to cool down the coolant enough to limit its temperature to 220oF. But the pressure in the entire coolant system now is greater than the outside air we are breathing. That means the coolant wants to get out, and it will, through any tiny crack it can find. Eventually some will get out and the coolant supply will decrease. If it decreases enough, the engine cannot be cooled enough and engine parts will expand and “seize”, ruining the engine.
How to avoid an overheated engine
To avoid this problem, the engine system has a clever makeup coolant tank connected to it through a check valve.`
What’s a check valve?
Here’s how to make one in your kitchen and see how one works. Take a throwaway plastic cup and make a round hole in its bottom. Take a round marble bigger than the hole and dump a lot of kitchen cleanser around the hole in the cup; then take the marble and rub it around the hole until it really make a nice round seat in the hole.
Now fill the cup half full of water. If you did a good job no water will sneak around the marble and drip out of the bottom of the cup. Hooray!
Now take your finger and slightly lift up the marble from beneath the cup, raising it slightly above the seat you created by scrubbing with cleanser (do it over the sink) and water will leak out on your finger.
You have just made a
one-way check valve
The coolant makeup tank has such a check valve in it but also has a spring to keep the ball pressed down on the valve seat. That side is toward the radiator, so that coolant under pressure cannot push back into the coolant makeup tank, which is under atmospheric pressure.
What happens when the car cools down?
When the coolant in the engine and radiator cools down to below boiling temperature, the steam that was above the liquid coolant will condense (turn back to water or coolant) and the coolant system will have a pressure that is less than the outside pressure of the air you are breathing………………a vacuum will form in the coolant system. Now it gets exciting.
The cycle reverses
While the engine was running, the hot coolant wanted to get out; but now that it has cooled down, the outside pressure (what you’re breathing) is more than the pressure in the coolant system (that includes the entire engine, the radiator and all the connecting hoses).
When this happens, the check value in the coolant is pushed by atmospheric pressure (the radiator side of this valve is simultaneously being “sucked” on by the vacuum in the coolant system), and fresh makeup coolant is pushed into the radiator, thereby replenishing coolant to normal.
So every time you stop and car and let the engine cool down, the whole system automatically restores the coolant level to normal without any driver assistance. Magic? You bet.
Always keep the coolant makeup reservoir at least half full. It’s usually under the hood in a plastic tank, nestled against the inside of one of the front fenders, and the coolant is always colored (in winter) so the level can be easily monitored.
Something to think about: The hot air you arrange to below on your feet, inside the car, is really inside air blowing across a very small radiator, just like the big job in front. It too goes through the same pressure increases and decreases as does the whole coolant system, since it is part of it.
So don’t ever kick with a sharp toe if you’re mad at it while the engine is running, or you will get a free bath of really, really hot, coolant water sprayed all over your feet.
