A corroded Patent Fuel cube. Patent fuel was a 19th-century artificial fuel made in Cardiff in Wales by mixing in a hydraulic press coal and binding substances, like pitch. [1] [2] There were many factories producing this product with the same recipe, thus the only way of identifying them is their shape and imprinted logos.
By summer 1893, Diesel had realised that his initial theory was erroneous, leading him to file another patent application for the corrected theory in 1893. [12] Diesel understood thermodynamics and the theoretical and practical constraints on fuel efficiency. He knew that as much as 90% of the energy available in the fuel is wasted in a steam ...
The Akroyd engine was the first functional internal combustion engine that could use petroleum oil as fuel. [8] It was operational in 1891, six years before the Diesel engine first ran. However, after the Diesel engine had proven successful, "Diesel engine" became the synonym for an engine that ran on any sort of petroleum oil.
Thomas Midgley Jr. (May 18, 1889 – November 2, 1944) was an American mechanical and chemical engineer.He played a major role in developing leaded gasoline (tetraethyl lead) and some of the first chlorofluorocarbons (CFCs), better known in the United States by the brand name Freon; both products were later banned from common use due to their harmful impact on human health and the environment.
The 100 known most prolific inventors based on worldwide utility patents are shown in the following table. While in many cases this is the number of utility patents granted by the United States Patent and Trademark Office, it may include utility patents granted by other countries, as noted by the source references for an inventor.
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.
Drawing the retorts at the Great Gas Establishment Brick Lane, from The Monthly Magazine (1821). The history of gaseous fuel, important for lighting, heating, and cooking purposes throughout most of the 19th century and the first half of the 20th century, began with the development of analytical and pneumatic chemistry in the 18th century.
In this manner, the engine fired on every power stroke and speed and output were controlled solely by the quantity of fuel injected. Bosch later further developed this type of metered injection system. In 1890 Brayton filed a patent (granted in 1892) for another 4 stroke engine with an air blast fuel injection system ( U.S. patent# 432,260) .
