There are two main types of stock: common stock and preferred stock.
Common stock represents ownership in a company and typically comes with voting rights.
Preferred stock usually does not have voting rights but has a higher claim on assets and earnings.
Stock can also be classified based on market capitalization (small-cap, mid-cap, large-cap) or sector (technology, healthcare, finance).
Thermostats can be categorized into mechanical, electronic, programmable, and smart thermostats.
Mechanical thermostats use a bimetallic strip to control temperature.
Electronic thermostats use electronic sensors to detect temperature changes.
Programmable thermostats allow users to set schedules for heating and cooling.
Smart thermostats can be controlled remotely via smartphone apps and may have features like learning al...
The question is asking about the engine specifications of a specific model.
Identify the specific model being referred to
Provide details about the engine specifications of that model
Include any unique features or upgrades of the engine
Cooling system is a mechanism used to remove heat from a space or substance to maintain a lower temperature.
Cooling systems can be found in various applications such as air conditioning units, refrigerators, and computer systems.
They typically involve the circulation of a coolant or refrigerant to absorb and transfer heat away from the desired area.
Cooling systems can be either air-cooled or liquid-cooled, depending on

I applied via Referral and was interviewed before Apr 2023. There was 1 interview round.
Pumps, fans, gearboxes, compressors, motors, and generators are essential components in various mechanical systems.
Pumps are used to move fluids, such as water or oil, through a system.
Fans are used to create airflow for cooling or ventilation purposes.
Gearboxes are used to transmit power from one component to another at different speeds or torques.
Compressors are used to increase the pressure of a gas, such as in air ...
Data collection process involves gathering, recording, and storing information for analysis and decision-making.

Two easy level and one medium level code
I applied via Naukri.com and was interviewed in Jul 2023. There were 2 interview rounds.
Technical and field related questions. Safety related questions were also included.
Pumps are mechanical devices used to move fluids by creating pressure.
Pumps work by converting mechanical energy into fluid energy.
They use impellers or rotors to create centrifugal force or positive displacement to move fluids.
Different types of pumps include centrifugal pumps, positive displacement pumps, and reciprocating pumps.
Examples of pumps include water pumps, fuel pumps, and hydraulic pumps.
I applied via Naukri.com and was interviewed in Jun 2020. There was 1 interview round.
Yes, I have worked on HHP Engines.
HHP stands for High Horsepower.
HHP Engines are commonly used in heavy-duty applications such as mining, construction, and marine industries.
Power ratings of HHP Engines can vary depending on the specific model and application.
For example, the Caterpillar C175-20 HHP Engine has a power rating of up to 4000 horsepower.
Other HHP Engines may have power ratings ranging from 1000 to 5000 hor
Engine derate refers to the reduction in engine power output due to various factors.
It can be caused by high altitude, high temperature, or poor fuel quality.
Derating can be temporary or permanent depending on the cause.
It is a safety feature that prevents engine damage and ensures reliable operation.
Derating can be indicated by warning lights or reduced performance.
Proper maintenance and monitoring can help prevent en
Turbocharger increases engine power by compressing air and increasing oxygen supply. Boost pressure improves engine performance.
Turbocharger is a device that uses exhaust gases to compress air and deliver it to the engine
It increases the density of air entering the engine, allowing more fuel to be burned and increasing power output
Boost pressure refers to the amount of pressure above atmospheric pressure that the turbo...
A lubrication system diagram shows the flow of oil or grease through the engine or machinery.
The diagram typically includes a pump, filter, oil cooler, and various lines and fittings.
It may also show the location of oil pressure sensors and switches.
The diagram can help identify potential issues with the lubrication system, such as blockages or leaks.
Examples of lubrication system diagrams can be found in service manua
The torque on cylinder head depends on the make and model of the engine.
The torque specification can be found in the engine manual.
It is important to use a torque wrench to ensure proper torque.
Over-tightening can cause damage to the engine, while under-tightening can cause leaks.
Different engines may have different torque specifications for the same cylinder head.
The torque may also vary depending on the type of bolts
A battery is a device that stores chemical energy and converts it into electrical energy. Charging circuit is used to replenish the energy in the battery.
A battery is composed of one or more electrochemical cells that convert stored chemical energy into electrical energy.
The charging circuit is responsible for supplying the necessary electrical current to reverse the chemical reactions within the battery and restore it...
