1893 Hornsby–Akroyd oil engine at the museum of Lincolnshire life, Lincoln, England 14 hp Hornsby–Akroyd oil engine at the Great Dorset Steam Fair in 2008. The Hornsby–Akroyd oil engine, named after its inventor Herbert Akroyd Stuart and the manufacturer Richard Hornsby & Sons, was the first successful design of an internal combustion engine using heavy oil as a fuel.
Pre-granal etioplasts, which are chloroplasts that have not matured but can be chloroplasts deprived of light, lack the active pigment. They can thereby can be considered leucoplasts.
Animation of a two-stroke engine. A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston (one up and one down movement) in one revolution of the crankshaft in contrast to a four-stroke engine which requires four strokes of the piston in two crankshaft revolutions to complete a power cycle.
The oil is dyed blue to make it easier to recognize in the gasoline. It appears black in this bottle because it is not diluted. Two-stroke oil (also referred to as two-cycle oil, 2-cycle oil, 2T oil, or 2-stroke oil) is a special type of motor oil intended for use in crankcase compression two-stroke engines, typical of small gasoline-powered ...
Hot-bulb engine (two-stroke). 1. Hot bulb. 2. Cylinder. 3. Piston. 4. Crankcase Old Swedish hot-bulb engine in action. The hot-bulb engine, also known as a semi-diesel [1] or Akroyd engine, is a type of internal combustion engine in which fuel ignites by coming in contact with a red-hot metal surface inside a bulb, followed by the introduction of air (oxygen) compressed into the hot-bulb ...
The Servi-Cycle was claimed to have a fuel economy of 100 mpg ‑US (120 mpg ‑imp; 2.4 L/100 km). [11] The Servi-Cycle used a magneto of Simplex's own design, providing 6 volt electricity for the dual ignition and for the headlight, taillight and stoplight. The engine had dual spark plugs in its cylinder head. [7]
In the two-stroke cycle, the four stages of internal combustion engine operation (intake, compression, ignition, exhaust) occur in one 360° revolution of the crank shaft, whereas in a four-stroke engine they take two complete revolutions. Consequently, in the two-stroke cycle the stages overlap through most of the engine's operation.
Joseph Day (1855 – 1946) is a little-known [1] English engineer who developed the extremely widely used crankcase-compression two-stroke petrol engine, [1] [2] as used for small engines from lawnmowers to mopeds and small motorcycles.
