The Monosoupape, was a rotary engine design first introduced in 1913 by Gnome Engine Company. It used a clever arrangement of internal transfer ports and a single pushrod-operated exhaust valve to replace the many moving parts found on more conventional rotary engines, and made the Monosoupape engines some of the most reliable of the era. British aircraft designer Thomas Sopwith described the Monosoupape as "one of the greatest single advances in aviation".
A hit-and-miss engine or Hit 'N' Miss is a type of stationary internal combustion engine that is controlled by a governor to only fire at a set speed. They are usually 4-stroke, but 2-stroke versions were also made. It was conceived in the late 19th century and produced by various companies from the 1890s through approximately the 1940s. The name comes from the speed control on these engines: they fire ("hit") only when operating at or below a set speed, and cycle without firing ("miss") when they exceed their set speed. This is as compared to the "throttle-governed" method of speed control. The sound made when the engine is running without a load is a distinctive "Snort POP whoosh whoosh whoosh whoosh snort POP" as the engine fires and then coasts until the speed decreases and it fires again to maintain its average speed. The snorting is caused by the atmospheric intake valve used on many of these engines.
The following outline is provided as an overview of and topical guide to automobiles:
The Lorraine 12H Pétrel was a French V-12 supercharged, geared piston aeroengine initially rated at 370 kW (500 hp), but later developed to give 640 kW (860 hp). It powered a variety of mostly French aircraft in the mid-1930s, several on an experimental basis.
High-speed steam engines were one of the final developments of the stationary steam engine. They ran at a high speed, of several hundred rpm, which was needed by tasks such as electricity generation.
The Austin 15-20 is the smaller-engined of the almost identical pair of new cars announced by Herbert Austin in February 1906. A very complete catalogue with detailed specifications was issued at the same time. As well as the engine's smaller bore the 15-20 differed from the 25-30 by being only available with a live rear axle and not chain-drive. Otherwise the specifications were the same, the very minor differences are detailed below.
The Potez 8D is the largest member of the Potez D series of air-cooled piston aircraft engines which share several common features. It is a supercharged eight cylinder inverted engine with a take-off power of 373 kW (500 hp).
The Renault 6Q, also called the Renault Bengali 6, is an air-cooled inverted in-line six-cylinder, aircraft piston engine, producing about 160 kW (220 hp) continuous power. It was designed and built in France and produced for more than ten years after its homologation in 1936, with large numbers built during World War II.
Their new Daimler 22 horsepower full-size luxury car was first displayed by Daimler in April 1902 at The Automobile Club’s Exhibition in London's Agricultural Hall. Daimler had elected to drop their multiple old low powered designs and restrict themselves to this 22 horsepower and a pair of 9 or 12 horsepower cars to the same design as the 22 but more lightly constructed. The King’s not quite finished new Daimler 22 was reported to be the chief attraction of the show.
The 4 VD 14,5/12-1 SRW is an inline four-cylinder diesel engine produced by the VEB IFA Motorenwerke Nordhausen from 1967 to 1990. The engine was one of the standard modular engines for agricultural and industrial use in the Comecon-countries. Approximately one million units were made.
The Mercedes-Benz OM 138 is a diesel engine manufactured by Daimler-Benz. In total, 5,719 units were produced between 1935 and 1940. It was the first diesel engine especially developed and made for a passenger car. The first vehicle powered by the OM 138 was the Mercedes-Benz W 138. The light Mercedes-Benz trucks L 1100 and L 1500 as well as the bus O 1500 were also offered with the OM 138 as an alternative to the standard Otto engine.
The Renault 100 hp, or 12B, aircraft engine from 1912 was a twelve-cylinder, air cooled 60° vee engine built by the French Renault company.
The Renault 130 hp V-12 aircraft engine is a twelve-cylinder, air cooled 90° vee engine built by the French Renault company.
The De Dion-Bouton 78 hp, typically referred to as De Dion-Bouton 80 hp, was an eight-cylinder, air cooled vee aircraft engine that has been built by De Dion-Bouton.
The De Dion-Bouton 130 hp aircraft engine, also referred to as De Dion-Bouton 12B, was a twelve-cylinder, air cooled vee aircraft engine that has been built by De Dion-Bouton.
The Renault 50/60 hp aircraft engines were a series of air cooled 90° V-8 engines with a bore and stroke of 90 mm × 120 mm built by the French Renault company in the years from 1908 to about 1911.
The Peugeot 8Aa, or L112, is a water-cooled V8 aircraft engine that equipped the 1,123 Voisin VIII bombers and fighters built during WW1. The 8Aa was the first engine designed by Peugeot for airplane use and the only one that saw service in WW1. In publications the engine is often referred to as the Peugeot 200 hp, or 220 hp. Voisin VIIIs formed the bulk of the French night bomber force through 1916-17 before being replaced in front line service by the Voisin X which was fitted with the more powerful and reliable Renault 12Fe.
