The exoskeletal engine (ESE) is a concept in turbomachinery design. Current gas turbine engines have central rotating shafts and fan-discs and are constructed mostly from heavy metals. They require lubricated bearings and need extensive cooling for hot components.
The AJD is a family of V6 and V8 turbodiesel engines with a clean-sheet architecture and variable valve timing developed by Ford of Europe for its then-subsidiaries Jaguar and Land Rover, as well as for its partner PSA Group working under the Gemini joint development and production agreement.
1928-1942 Indian Four straight-4 motorcycle engine. Straight engines (also known as "inline engines") have all cylinders aligned in one row along the crankshaft with no offset. When a straight engine is mounted at an angle, it is sometimes called a "slant engine". Types of straight engines include: Single cylinder; Straight-2, also known as ...
The engine performance deteriorates with use as parts wear, meaning the engine has to use more fuel to get the required thrust. A new engine starts with a reserve of performance which is gradually eroded. The reserve is known as its temperature margin and is seen by a pilot as the EGT margin. For a new CFM International CFM56-3 the margin is 53 ...

Reduced engine weight – The mass of the connecting rods and overall materials used in building the engine frame is reduced, which helps the engine gain better power and fuel efficiency. [ 6 ] The i-VTEC technology is also integrated into Honda's hybrid vehicles to work in tandem with an electric motor .
Seen on the runways of Max Mara, Louis Vuitton, and Christian Dior, the fanny pack—once considered solely functional for hands-free convenience—has transformed itself into a signifier of style ...
Engine balance refers to how the inertial forces produced by moving parts in an internal combustion engine or steam engine are neutralised with counterweights and balance shafts, to prevent unpleasant and potentially damaging vibration. The strongest inertial forces occur at crankshaft speed (first-order forces) and balance is mandatory, while ...
