Diagram of how a Buoyancy Engine works. A buoyancy engine is a device that alters the buoyancy of a vehicle or object in order to either move it vertically, as in the case of underwater profiling floats and stealth buoys, or provide forward motion (therefore providing variable-buoyancy propulsion) such as with underwater gliders and some autonomous aircraft.
Float chamber (left) of an updraught carburettor, showing the float (4) and valve (5). A float chamber is a device for automatically regulating the supply of a liquid to a system. It is most typically found in the carburettor of an internal combustion engine , where it automatically meters the fuel supply to the engine.
The common valve spring system is satisfactory for traditional mass-produced engines that do not rev highly and are of a design that requires low maintenance. [1] At the period of initial desmodromic development, valve springs were a major limitation on engine performance because they would break from metal fatigue.
Kart racing or karting is a motorsport discipline using open-wheel, four-wheeled vehicles known as go-karts or shifter karts. They are usually raced on scaled-down circuits , although some professional kart races are also held on full-size motorsport circuits.
Unlike the float-type carburetor fuel system that relies on venturi suction to draw fuel into the engine, a pressure carburetor only uses the venturi to measure the mass airflow into the engine and manages the flow of fuel that is continuously under pressure from the fuel pump to the spray nozzle.
Rupp karts featured single- or dual-engine models with behind-seat-mounted fuel tanks. Rupp would eventually introduce a kart with four-wheel independent suspension. [3] The first Rupp karts introduced were called Dart Karts. Rupp also produced the A-Bone, A-Bone Deuce (both pictured to the right), Lancer, Monza Jr. and later the J Dart Kart.
A float carburetor uses the venturi effect to supply fuel into the engine intake; this depends upon a constant level of fuel in the float bowl to maintain the desired fuel/air mixture. The float operates a valve which keeps the fuel level in the carburetor consistent despite varying demands by means of a linked float valve. As the fuel level ...
Original Kart, commonly abbreviated as OK, is a kart racing class for drivers aged 14 and over, sanctioned by the CIK-FIA. OK is the primary direct-drive class in FIA championships . The class was originally called Intercontinental A ( ICA ), first introduced in 1981 at the European Championship as a secondary direct-drive class to Formula K .
