Mike Brown's 20 HP Steam Engine |
|
This two-cylinder, 20-horsepower, 3 x 4-inch, double-acting, 90° "V" engine is designed in the simplest possible form for steady-state power production. It will produce 20 hp with a maximum of 200 psig @ 700 rpm. It is well balanced for those parameters and is designed for self-starting. Its low-speed torque is in the order of 200 ft-lb and should be handled carefully.
It has very large balanced piston valves that will greatly increase its efficiency and can stand a considerable amount of superheat. Its nominal cutoffs are 55% admission and 65% exhaust. Cylinder clearance volume is in the order of 12?13% and will allow for moderate compression, which helps in starting the engine from cold. Admission starts at 1% before dead centers to aid in high-speed running with the standard 55° eccentrics.
This engine is not equipped with reverse or variable valve timing. Power can be increased by changing the eccentric angle to 60- 65°, but this also decreases engine efficiency.
This engine has a drip valve on the bottom of each valve bore to augment getting rid of condensed water when the engine is started from cold. Hydraulic lock and damage can occur when a piston-valve engine is started carelessly from cold.
The two-cylinder "V" engine design was used with great success for small engines by Abner Doble and by Bill Besler in his famous steam-powered airplane. It is the simplest and lightest configuration for a two-cylinder engine and requires only two crankwebs and a crankshaft of only five parts. The intake and exhaust manifolds are not included. Motor mount brackets can be made out of 1-1/2" steel angle iron 18" to 24" long and bolted to the two bottom holes in each end plate.
WARRANTY
Brown's engines are guaranteed for two (2) years, parts and labor. The engines should last a considerable longer time than that. However, the engine bearings and the piston rings may have to be replaced after 8,000 to 10,000 hours. At full power, a modern automotive engine will last only 50 to 100 hours.
The warranty is voided if you don't lubricate the engine, if you run it at pressures and speeds beyond that specified, or if you do something else demonstrating a serious lack of intelligence--like dropping it out of a second-story window.
30-day money-back guarantee if you return the engine in undamaged condition. There is a $750.00 restocking charge.
SPECIFICATIONS:
- 20-Horsepower at 200 psi and 700 rpm.
- Approximate weight 150 pounds.
- 2 cylinders 3-inch bore, 4-inch stroke, double-acting, 90 "V".
BOILERS
Boilers are available in 6-horsepower configuration that can be added in a "gang run" system. That is, add another boiler every time you want to increase horsepower--from 6 horsepower to 12 horsepower, to 18 horsepower, etc. This adds to engine efficiency and makes it much cheaper to get started.
For example, if you only need 5 or 6 horsepower at the moment and you are running a single 20-hp steam boiler, you will waste a lot of fuel. The Titanic had only two piston steam engines and 33 boilers.
6-hp boilers are available at $6,500 each.
