Brow Steam Car Powerplant Diagram, 2010

Here is a scanned page from my invention notebooks, page 47, volume XLVI. Explanatory text will be added gradually in the future.

If the whole jpeg doesn't load by itself, as it doesn't for me, try right-clicking on the image, then click on "View Original Image" from the pop-up menu. Well, this works for me with XP.

The basics on how this steam automobile propulsion system works are as follows:

A gasoline burner heats steel tubing in the boiler, thus heating and boiling water inside the tubing, and turning it into pressurized steam. A throttle, operated by a small hand lever on the steering wheel column, sends steam through a superheater tube, and into the main steam line, where a small oil pump adds oil to lubricate the valves, cylinders, and sliding rods in the steam engine. The oiled steam then passes through 2 steel flex-pipes to the engine, which is mounted on the rear axle.

In the engine, the steam pressure moves pistons and connecting rods, which turn a crankshaft. This action is similar to the operation of a gas engine. With this steam engine, however, no clutch or transmission is needed. The engine crankshaft has a gear on it, which meshes with a gear in the axle, thus when the engine turns the axle shafts and wheels turn too, thus propelling the car.

Exhaust steam from the steam engine passes through 4 hoses into 4 straight copper pipes suspended horizontally just below the bottom of the car. From these air-cooled pipes, in which the steam starts to cool and condense, the steam passes to the main condenser (like a radiator) at the front of the car, where it turns into water and enters the water tank.

The water pump takes water from this tank and pumps it to the boiler. When the water is low in the boiler, a control valve -- the Feedwater Automatic -- closes, and water enters the boiler. When the boiler is filled to its operating level, the Feedwater Automatic opens, bypassing water back to the main tank. On the way back to the main water tank, the bypassed water fills up, and then continuously overflows from, an automatic Refill Tank on top of the boiler.

The fuel system which supplies gasoline to the burner operates with a similar bypass-pumping control system. Like the feedwater pump and the oil pumps, the fuel pump is a plunger-type pump, driven directly from the engine via an eccentric on an auxiliary drive shaft linked to the engine crankshaft. Whenever the engine is turning, the car is also moving, and the pumps are pumping. The fuel pump sucks fuel through a hose from the bottom of the fuel tank, then through a fuel filter, then to a fuel pressure tank next to the main fuel tank in the back of the car. When the fuel pressure tank reaches its maximum pressure, a Fuel Automatic valve inside the fuel tank is opened by the pressure and bypasses fuel to the main fuel tank. Thus the fuel pressure tank can never exceed its maximum pressure, and is always kept full while the car is running.

This fuel pressure tank then supplies gasoline under pressure to the burner, via a number of control valves. It also allows the pilot light to run for up to 3 days on standby, keeping the car ready to go instantly.

There are a number of other details in the powerplant, and in this system diagram, which, by the way, is only about 90% complete.

For example, the cluster of controls to the right of the boiler in the diagram, automatically blow off and refill/restart the boiler.

Some parts in this diagram are drawn somewhat differently from how they are actually built or located, for ease of drawing.

This diagram is rather crudely drawn, because I am putting my time and effort into completing blueprints and building working equipment, rather than into good drawings and graphics. Getting out the drafting tools and drawing a tidy system diagram would take many hours, which at this point are better spent elsewhere.

More explanations of the details in this system diagram will be forthcoming. In the meantime, perhaps you can figure out how some of the freezeproofing, oil recycling, bubble-overload-condensing, and other features work. Two big omissions -- for diagram clarity reasons -- are the Levermatic control and FuelMaster control, which link together and coordinate all the controls which are shown in this current diagram.

Some of the details in this diagram are already explained on my "Latest News" page. I hope that this diagram will make some of my notes there easier to understand.
