Before the invention of precombustion chamber injection, air-blast injection was the only way a properly working internal air fuel mixture system could be built, required for a Diesel engine. During the 1920s, [2] air-blast injection was rendered obsolete by superior injection system designs that allowed much smaller but more powerful engines. [3]
A Med-E-Jet vaccination gun from 1980. A jet injector, also known as a jet gun injector, air gun, or pneumatic injector, is a medical instrument that uses a high-pressure jet of liquid medication to penetrate the skin and deliver medication under the skin without a needle.
The injection scheme is always intermittent (either sequential or cylinder-individual). This can be done either with a blast of air [4] or hydraulically, with the latter method being more common in automotive engines. Typically, hydraulic direct injection systems spray fuel into the air inside the cylinder or combustion chamber.
The fuel pump is mounted above the cylinder head and driven by the camshaft, [21] the air-blast pump is cast onto the cylinder and driven via a lever by two connecting rods from the engine's piston rod. [26] Like all air-blast injected diesel engines, the Motor 250/400 has a compressed gas bottle for the injection air.
During January that year, an air-blast injection system was added to the engine's cylinder head and tested. [38] Friedrich Sass argues that, it can be presumed that Diesel copied the concept of air-blast injection from George B. Brayton, [32] albeit that Diesel substantially improved the system. [39]
Of all the drugs discussed, this one generally provides the best results for appropriate candidates. Though complications rarely arise, they are often the result of the injection rather than the drug.
Brayton air blast injection system 1890 Brayton direct injection 1887. In 1887 Brayton constructed a 4 stroke engine that used a glowing platinum igniter as a source for ignition and a metered pressurized injection system with an oil atomizing direct fuel injector (U.S. patent #432,114).
The ad cost $14 million to air in the first half, according to tech publication The Verge. "It's understandable given that, with the amount of money invested in the spot, the audience really was ...
