HLS Asia Interview Questions and Answers
9 Interview questions
The efficiency of an I.C. engine can vary depending on factors such as design, fuel type, and operating conditions.
Efficiency of I.C. engines typically ranges from 20% to 40%, with some high-performance engines reaching up to 50%.
Factors affecting efficiency include compression ratio, combustion process, and heat transfer losses.
Improvements in engine design, such as turbocharging and direct injection, can increas...
A circuit breaker is an electrical switch designed to protect an electrical circuit from damage caused by excess current.
Automatically interrupts the flow of electricity when a fault is detected
Can be reset manually after tripping
Protects electrical devices and wiring from damage
Commonly used in homes, buildings, and industrial settings
Diesel engines generally require more maintenance than gasoline engines.
Diesel engines have more complex systems and components that require regular maintenance.
Diesel engines require more frequent oil changes and fuel filter replacements.
Diesel engines may require additional maintenance for emissions control systems.
Gasoline engines generally have simpler maintenance requirements.
Petrol engines use spark ignition, while diesel engines use compression ignition.
Petrol engines use spark plugs to ignite the fuel-air mixture, while diesel engines rely on compression to ignite the fuel.
Petrol engines typically have higher RPM (revolutions per minute) compared to diesel engines.
Diesel engines are more fuel-efficient than petrol engines.
Petrol engines are generally quieter and smoother in operatio...
It depends on the specific engines being compared.
Engine power can vary greatly depending on factors such as size, design, and technology.
For example, a high-performance sports car engine may be more powerful than a small economy car engine.
Comparing specific engines would be necessary to determine which is more powerful.
No, diesel engines are designed to run on diesel fuel, not petrol.
Diesel engines require diesel fuel for proper combustion
Petrol has different combustion properties compared to diesel
Running a diesel engine on petrol can cause damage to the engine components
The engine may not run efficiently or may not run at all
A diode is a semiconductor device that allows current to flow in one direction only.
Diodes have two terminals - an anode and a cathode.
They have a forward voltage drop, typically around 0.7V for silicon diodes.
Diodes exhibit non-linear current-voltage characteristics.
They are commonly used in rectifiers, voltage regulators, and signal demodulation.
Examples of diodes include silicon diodes, Schottky diodes, and lig...
The earphone converts electrical signals into sound waves, the battery provides electrical energy to start the vehicle, and the mobile charges by converting electrical energy into stored energy.
Earphones work by receiving electrical signals from a device and converting them into sound waves that can be heard by the user.
The battery in a vehicle provides the necessary electrical energy to start the engine by supply...
IC engine has 4 strokes: intake, compression, power, and exhaust. Spark plug ignites fuel-air mixture. Voltage supply ensures spark plug works.
Intake stroke: fuel-air mixture enters the cylinder
Compression stroke: mixture is compressed by the piston
Power stroke: spark plug ignites mixture, causing an explosion that pushes the piston down
Exhaust stroke: piston pushes exhaust gases out of the cylinder
Spark plug crea...
