In 1896 they built lamp start oil engines. The Lamp or hot-bulb engine (also hotbulb or heavy-oil engine) is a type of internal combustion engine. It is an engine in which fuel is ignited by being brought into contact with a red-hot metal surface inside a bulb, followed by the introduction of air (oxygen) compressed into the hot-bulb chamber by the rising piston. There is some ignition when the fuel is introduced, but it quickly uses up the available oxygen in the bulb. Vigorous ignition takes place only when sufficient oxygen is supplied to the hot-bulb chamber on the compression stroke of the engine. Most hot-bulb engines were produced as one-cylinder, low-speed two-stroke crankcase scavenged units Historic - Industrial - single cylinder, horizontal, 4 stroke, hot-bulb ignition oil engine Blackstone 8HP Oil Engine made from steel, wrought iron and brassOval Plate with Black Stones and Clutter Buck Brass Plaque engine number 71076blackstone, oil engine, clutter buck, black stone, puffing billy, hit and miss, engine, blackstone & co
