Four-stroke cycle used in gasoline/petrol engines: intake (1), compression (2), power (3), and exhaust (4). The right blue side is the intake port and the left brown side is the exhaust port. The cylinder wall is a thin sleeve surrounding the piston head which creates a space for the combustion of fuel and the genesis of mechanical energy.
Diesel engine runaway is an occurrence in diesel engines, in which the engine draws extra fuel from an unintended source and overspeeds at higher and higher RPM, producing up to ten times the engine's rated output until destroyed by mechanical failure or bearing seizure due to a lack of lubrication. [1] Hot-bulb engines and jet engines can also ...
The Scuderi engine is a design of a split-cycle, internal combustion engine invented by Carmelo J. Scuderi. [2] The Scuderi Group, an engineering and licensing company based in West Springfield, Massachusetts and founded by Carmelo Scuderi’s children, said that the prototype was completed and was unveiled to the public on April 20, 2009.

John Deere 720. In 1956, the 70 was replaced by the John Deere 720 with freshened up styling. The 720 was the largest two-cylinder tractor to be offered by Deere and the most powerful row-crop tractor of the time. The 720's gasoline engine developed 65 horsepower (48 kW). [2] [8] [9]
A typical 6-horsepower (4.5 kW) engine weighs approximately 1,000 pounds (450 kilograms). Typically, the material for all significant engine parts was cast iron. Small functional pieces were made of steel and machined to tolerance. [1] The fuel system of a hit-and-miss engine consists of a fuel tank, fuel line, check valve, and fuel mixer
In 1940. the 14-horsepower (10 kW) LA was introduced, using a John Deere engine, and the L received a Deere engine in lieu of the Hercules. The LA introduced a power take-off to the L line. Both the L and LA were produced at the same time. Ls and LAs used only gasoline as fuel. Production ended in 1946. [1] [2] [3] [4]
The John Deere Model R tractor was John Deere's first diesel tractor. A large, heavy tractor, it had fixed wheel widths and was not produced as a row-crop tractor with adjustable axles. The R was followed in the John Deere numbered model series by the John Deere 80, 820 and 830 tractors, which represented evolutionary upgrades to the basic R.
