Used for increasing the pressure of air above atmospheric pressure. Which of the following types of superchargers are not preferred.
Answer: d.Clarification: The supercharging used for an improved cold start, increased gas loading, reduced exhaust smoke, increased mechanical efficiency, etc. Answer: a.Clarification: The supercharger increases the power output of the engine by increasing the charge pressure. The engine crankshaft is coupled with the air compressor of the supercharger which drives the air compressor in the supercharger.
To elaborate: Engine is used to run mechanically driven supercharger. The engine crankshaft is coupled with the air compressor of the supercharger which drives the air compressor in the supercharger.
This gives each intake cycle of the engine more oxygen, letting it burn more fuel and do more work, thus increasing the power output. Power for the supercharger can be provided mechanically by means of a belt, shaft, or chain connected to the engine’s crankshaft. Common usage restricts the term supercharger to mechanically driven units; when power is instead provided by a…..
Supercharger, in piston-type internal-combustion engines, air compressor or blower used to increase the intake manifold pressure of the engine. In aircraft piston engines, supercharging compensates for the reduced atmospheric pressure at high altitudes. Development of the gas turbine, which requires constant flow of air and fuel, brought the introduction of the turbosupercharger, or simply turbocharger, a centrifugal blower driven by a small gas turbine powered by the exhaust gases from the engine cylinders.
supercharging air compressor is driven by mcq Related Question:
What is supercharging Mcq answer?
Supercharging increases the power output of the engine by. Solution: The method of supplying air or air-fuel mixture higher than the pressure at which the engine naturally aspirates, by means of a boosting device is called supercharger.
Which compressor is used for supercharging?
A number of compressor and blower types have been used as superchargers, including Roots blowers, sliding vane compressors, screw compressors, rotary piston pumps, spiral-type superchargers, variable displacement piston superchargers, and centrifugal compressors.
Which of the following is not an objective of supercharging Mcq?
Which of the following is not an objective of supercharging? To reduce the weight to power ratio.
What is supercharging in power plant?
A supercharger is an air compressor that increases the pressure or density of air supplied to an internal combustion engine. This gives each intake cycle of the engine more oxygen, letting it burn more fuel and do more work, thus increasing the power output.
What is supercharging exam Veda?
Solution(By Examveda Team) Supercharging is the process of supplying the intake air to the engine cylinder at a density Greater than the density of the surrounding atmosphere.
What is scavenging air Mcq?
Scavenging air in a diesel engine means air used for forcing burnt gases out of the engine’s cylinder during the exhaust period.
Which compressor is used in gas turbine?
Centrifugal compressors are used to power gas turbine engines used in jet aircraft, energy production, and other heavy industry applications. In a gas turbine, the centrifugal compressor transfers energy from impeller blades.
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.
Where is the reciprocating compressor mostly used?
Reciprocating compressors can be used in almost any compression application, but other compressor types are generally preferred for certain applications. Centrifugal compressors tend to be preferred when the power is above 2 MW, the mole weight (MW) is greater than 10, and the discharge pressure below 100 MPa.
Which of the following is correct for supercharging?
This reduces ignition delay in the CI engine, thereby the combustion becomes smooth, and the tendency for knocking is avoided. In the SI engine the short ignition delay promotes detonation. Hence supercharging is preferred in a diesel engines than in a petrol engine.
What is the purpose of employing supercharging for an engine Mcq?
the main objective of supercharging is to obtain more power by burning a larger amount of fuel or to reduce the weight and size of the engine for a given power output. It is a method of increasing the power output of the engine without increasing its weight and size.
Is a centrifugal supercharger belt driven?
Centrifugal superchargers are belt-driven superchargers that deliver forced air, or boost, into an engine. That belt drives a pulley that is connected to a set of gears that drive an impeller in a compressor housing.
What is the method of supercharging?
Basically supercharging means supplying high pressure air to the engine. When the high pressure air is supplied to the engine, the mass flow rate of fuel also increases and consequently it results in more power output. Hence the efficiency of the engine also increases.
What do superchargers 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 supercharging What are the methods for supercharging?
Supercharging is a method consisting of a preliminary compression with the aim of increasing motors’ air intake density to boost their specific power (energy by swept volume) [15].
