This 300 N cryogenic propellant engine has a vacuum Isp of 415 seconds - the highest value ever achieved in Europe for an engine of such small size. Being pressure-fed‚ the engine assembly is relatively simple and avoids the need for a turbo-pump. The thrust chamber and throat region of the engine are regeneratively cooled using hydrogen propellant. The nozzle extension is radiation cooled. The engine incorporates a splash-plate injector having a star shaped configuration. Ignition and subsequent

Parts of the marine diesel engine Below is a cross-sectional view of a Sulzer Main Diesel Engine and the names of the component parts. The starting air valve is used to lead highly compressed air to push the piston for turning the engine when starting. In this 2-stroke engine‚ the air intake and exhaust are taken into the engine cylinder liner through scavenging ports and exhaust ports. The cylinder head covers the top of the cylinder and houses the starting air valve‚ fuel valve or injector

Matt Bagley English 110 Process Essay Process of a 4-stroke Internal Combustion Engine A common phrase that is heard whilst growing up is "curiosity killed the cat". This phrase might be true but; "ingenuity brought the cat back". Having a mindset in which giving up is never an option has plagued most inventors of the modern day‚ especially a high school drop out named Nikolaus August Otto‚ born in 1832. Otto was responsible for the development and improvement of the 4-stroke motor that

in inches of mercury (in. Hg). A quick snap of the throttle plate should drop the vacuum to around 5 in. Hg (inches of mercury)‚ and then it should recover to a steady 21 in. Hg. When this air is mixed with atomized fuel from the fuel injectors‚ engine speed is increased. It’s important to remember for every 1000 ft. of increase in altitude 1 in. Hg is subtracted from the reading. For instance‚ if specifications required 21 in. Hg at an altitude of 3000 ft. above sea level‚ a reading of 18 in. Hg

This car is powered by a two cylinder compressed engine. This engine can run either on compressed air alone or act as an IC engine. Compressed air is stored in glass or fiber tanks at a pressure of 4351 psi. [pic] Within the next two years‚ you could see the first air-powered vehicle motoring through your town. Most likely‚ it
