What is the main objective of supercharging engine Mcq?
The purpose of supercharging an engine is to raise the density of the air charge, before it enters the cylinders. Thus, the increased mass of air will be inducted which will then be compressed in each cylinder. This makes more oxygen available for combustion.
What is the supercharging process?
Supercharging is the process of supplying the intake of an engine with air at a density greater than the density of surrounding atmosphere so that each intake cycle of engine gets more oxygen , which burns more fuel thus generating more power .
What is supercharging state advantages of supercharging?
Supercharging increases power output of an engine without increasing fuel consumption. Certain amount of power generated by the engine goes for the compression of air but overall power output is more. The engine which is to be used with a supercharger is made to withstand higher forces due to supercharging.
What is supercharging MCQS?
Solution(By Examveda Team)
Supercharging is the process of Supplying the intake of an engine with air at a density greater than the density of the surrounding atmosphere.
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.
Does a supercharger use more fuel?
Because a supercharger uses the engine’s own power to spin itself, it siphons power—more and more of it as engine revs climb. Supercharged engines tend to be less fuel efficient for this reason.
Which is faster supercharger or turbo?
A turbo is more efficient than a supercharger since your engine does not need to work harder to power the turbo. Because a turbo is not connected directly to the engine, it can spin much faster than a supercharger.
How much does supercharging cost?
If you charge at a supercharger, the cost is typically about $0.25 per KW if you purchased a Model S or Model X after January 2017. Supercharging is free for cars purchased before, January 2017. If you charge at home, the local cost of electricity will determine your overall charging cost.
How knocking can be reduced?
In spark ignition (SI) engines, the possibility of knocking can be reduced by decreasing compression ratio as a reduction in compression ratio will result in the generation of lower peak temperature. … High inlet temp of the air-fuel mixture will increase knocking.
Does a supercharger decrease engine life?
Assuming a properly tuned system, proper oil change and engine maintenance, and similar driving, supercharging generally will not shorten the life of an engine, just as is the case with OEM turbocharging (with proper cooldown for turbochargers.
Is a supercharger more reliable than a turbo?
Superchargers are arguably more reliable than turbochargers. They’re easy to install and maintain. They’re louder than turbochargers—they enhance the RPMs by a considerable amount—and they’re also more common as a result.
