Newer designs are OPOC, Goole, Pinnacle, Achates Power, Laukötter among others. Almost all engines were, or are, two-stroke diesel engines.
The presented model engine is a four-stroke engine with two cylinders and crankshafts which are connected by a toothed belt. The pistons run opposite to each other and therefore run smoothly.
Thanks to hardened pistons and cylinder liners the engine needs little lubrication; lighter gas is used as fuel and therefore the engine is almost free of exhaust gases. The piezoelectric ignition is driven by the camshaft or flywheel shaft. Starting takes place by rotation of the flywheel.
The engine consists largely of anodized aluminium and nickel-plated brass.
The model engine comes complete and ready to run. Gas is not supplied but it can run off any butane or propane source. Click here for a supplier of butane in the uk.
