Assertion: A judo fighter in order to throw his opponent on to the mat tries to initially bend his opponent and then rotate him around his hip. Reason: As the mass of opponent is brought closer to the fighter’s hip, the force required to throw the opponent is reduced. A. If both assertion and reason are true and reason is the correct explanation of assertion.
supercharging air compressor is driven by Related Question:
What drives the supercharger compressor?
Superchargers are typically driven via a mechanical drive—usually a belt—connected to the engine’s crankshaft. An electric motor can also be used to drive the supercharger, especially if the vehicle already has an electrical system with sufficient capacity.
How does a supercharger compressor work?
Superchargers increase intake by compressing air above atmospheric pressure without creating a vacuum. This forces more air into the engine, providing a boost. With the additional air, more fuel can be added to the charge, and the power of the engine is increased.
How is an aircraft supercharger driven?
A supercharger relies on an engine-driven air pump or compressor, while a turbocharger gets its power from the exhaust stream that runs through a turbine, which in turn spins the compressor. Aircraft with these systems have a manifold pressure gauge, which displays MAP within the engine’s intake manifold.
How is the air compressor driven in a piston engine supercharger?
supercharger, in piston-type internal-combustion engines, air compressor or blower used to increase the intake manifold pressure of the engine. Higher pressure increases the mass of air drawn into the cylinders by the pumping action of the pistons during each intake stroke.
Are superchargers belt driven?
Any supercharger is belt driven off of your accessory belts. As such its driven speed is directly connected to engine speed. If you double the engine speed the superchargers driven speed doubles.
Where does a supercharger mount?
The centrifugal supercharger is generally attached to the front of the engine with a rigid bracket and driven via a belt-drive or gear-drive from the engine’s crankshaft.
Whats a supercharger do?
A supercharger is an air compressor that increases the pressure of air supplied to an internal combustion engine. This aids in higher power output as the engine gets more oxygen in each of its intake cycles and helps it to burn more fuel.
What is meant by a supercharger?
Definition of supercharger : a device (such as a blower or compressor) for pressurizing the cabin of an airplane or for increasing the volume air charge of an internal combustion engine over that which would normally be drawn in through the pumping action of the pistons.
How is the air compressor driven in a position engine turbocharger?
A turbocharger consists of a compressor wheel and exhaust gas turbine wheel coupled together by a solid shaft and that is used to boost the intake air pressure of an internal combustion engine. The exhaust gas turbine extracts energy from the exhaust gas and uses it to drive the compressor and overcome friction.
What is a two stage supercharger?
A two stage supercharger used a compressor with two or more compression stages, often with an inter cooler between them, driven by a transmission with different gear ratios to control the compressor speed. A schematic of this type of supercharger can be seen here on a Rolls Royce Eagle engine.
What is external supercharger?
Externally driven superchargers (turbosuperchargers) are designed to deliver compressed air to the inlet of the carburetor or fuel/air control unit of an engine.
What type of pump is a supercharger?
Superchargers are mechanically, electrically, or hydraulically driven pumps, compressors, or blowers employed to boost the pressure of the charge air in diesel engines or of the intake charge mixture in spark ignited engines. Most superchargers have traditionally been built around positive displacement compressors.
Is compressor same as supercharger?
Yes. A supercharger and a turbo are both air compressors. They force air extra air into the engine by compressing it.
What is a supercharger blower?
A blower is just another name for a supercharger, particularly roots-type supercharger, which is probably one of the oldest styles of supercharger. At the heart of the roots-type supercharger are two counter-rotating meshed lobed rotors.
Does a supercharger need an intercooler?
Intercoolers are required for superchargers to ensure peak performance and longevity of your engine. The compressed air coming from the supercharger is too hot for combustion – it has to be cooled by intercoolers first.
