Diesel engines are internal combustion engines. The main difference compared to other internal combustion engines is how the fuel is ignited. Hot air from the compressor is transferred to the combustion chamber, but instead of requiring an ignitor, the air is hot enough that when the fuel is injected, it spontaneously combusts. Spontaneous combustion is the result of two things, the self-ignition temperature of diesel and the compression ratio of diesel engines.  Read more >>

A Swiss engineer, Alfred Buchi, patented the turbocharger in 1905, but it wasn’t used until 1923 when it was incorporated into large marine engines used in the construction of two passenger liners. This was commissioned by the German Ministry of Transport. Turbochargers were first used in production aircraft engines in the 1920s but were kept out of widespread use due to the need for high-temperature metals for the turbine. Using turbochargers can improve an engine's fuel efficiency, reduce emissions, and generate more power. Read more >>

Aircraft bearings require a special grease in order to operate properly and ensure longevity. Automotive grease can be used as a cheap alternative, but it is not recommended if you want all your parts to stay reliable and in pristine condition. After all, the needs of an automobile and the needs of an aircraft are entirely different. In terms of aircraft maintenance, there are three types of grease that are highly recommended: Mobil SHC100, Braycote 622, and ROYCO 22CF. Read more >>

It’s always easy to mistake two similar things as the exact same thing. Jam and jelly, weather and climate, and pumps and compressors. While sometimes misunderstanding the difference is no big deal, other times it means that you just bought the wrong mechanical device for your project.   Read more >>

Humans travel a lot. Whether by car or by plane, as a collective, humans travel a lot. And in doing so, we’ve driven an entire industry without even knowing it. To be specific, the wheels and brakes industry. From manufacturing to maintenance and servicing, the wheels and brakes of aircraft and ground vehicles alike have begun to develop at alarming speeds.  Read more >>
