PowerHouse 4-Cycle Gas Engine Plans
Plans to build the PowerHouse 4-Cycle Gas Engine The “PowerHouse” engine is a long stroke design for medium to low speed operation. By having a long stroke, it is capable driving a load such as a generator or pump at a leisurely pace. It is made from bar stock and was designed to be as easy to build as possible while retaining good looks. The frame and base plate is from aluminum alloy plate. The cylinder, piston and head are of cast iron bar stock; and the flywheel is of mild steel. The engine is air cooled by fan (belt driven or electric), although it will also operate without one. Spark advance/retard is adjustable while the engine is running. The carburetor is an easy to build type with adjustable speed control and an air cleaner. The engine will run an hour or so on 2 ounces of fuel. You will need a 6″ lathe and a small milling machine with a 6″ diameter rotary table. This engine should be as easy for beginners to build as any, and easier than most because the engine frame is so simple. The model runs from 500 RPM idle to around 1,800 RPM or so wide open and the sound is real nice with the right exhaust pipe at about 800 RPM. The plans set consists of 16 sheets of quality laser printed CAD drawings and 1 sheet of construction and assembly notes.Specifications: Flywheel Dia.: 4.7″, Cylinder Bore: 1″, Piston Stroke: 1-1/2″, Overall Length: 11-1/4″, Height: 5″ (lubricator) All of our plans projects are machined from metal bar stock (supplied by you, the builder) and no castings are required. This is the lowest cost way for you to build as the metals can usually be purchased from metal salvage yards for around $2.00 or so per pound for aluminum, brass and stainless steel. But as can be seen, most of the model engines are designed to look like they were in fact made from castings instead of rectangular blocks and round bars of metal. High precision machining is required. Experience building other types of engines from scratch is suggested.You will need a lathe and a milling machine with the usual tooling items. You will need a horizontal/vertical rotary table for your mill if you want to duplicate the visual design aspects of some of the projects – spoked flywheels, fluted columns etc., but the engines will operate just as well without those features. Please note – we do not have any ready to run engines or bolt together engine kits for sale. The plans are for model engines – the engines can be scaled to any size, but no claims of suitability for practical power generation are made.The Plans Set drawings are high quality computer generated drawings using a professional CAD (Computer Aided Design) program and printed on 8-1/2″ x 11″ sheets with a laser printer. This permits you to insert them in plastic sheet protectors so they won’t get soiled as you use them in the shop. Dimensions are in U.S. inch decimals – no fractions – which makes it easy for you to change the scale of your model to suit your machine tool capacity or the materials you have on hand or have access to. Multiply dimensions by 25.4 to obtain millimeter dimensions.
