All Cummins engine questions
Cummins engines are available in various types including diesel, natural gas, and hybrid options.
Cummins diesel engines are commonly used in heavy-duty trucks and construction equipment
Cummins natural gas engines are popular for use in buses and other transportation vehicles
Cummins offers hybrid engines that combine diesel and electric power for increased efficiency
Other types of Cummins engines include marine engines
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

The weight of plates can be calculated by multiplying the density of the material by the volume of the plate.
Determine the density of the material the plate is made of (e.g. steel has a density of 7850 kg/m^3)
Measure the dimensions of the plate (length, width, thickness)
Calculate the volume of the plate using the formula: volume = length x width x thickness
Multiply the volume by the density to get the weight of the pla
There are various types of mechanical tools used in construction and maintenance work.
Hand tools (e.g. hammer, screwdriver, wrench)
Power tools (e.g. drill, saw, grinder)
Heavy equipment (e.g. excavator, bulldozer, crane)
Measuring tools (e.g. tape measure, level, calipers)
There are mainly three types of beams: Simply supported beam, Cantilever beam, and Overhanging beam.
Simply supported beam is supported at both ends and carries load in the middle.
Cantilever beam is supported at one end and carries load at the other end.
Overhanging beam has one or both ends extending beyond its supports.
There are several types of flanges used in piping systems for connecting pipes, valves, and other equipment.
Weld Neck Flange
Slip On Flange
Socket Weld Flange
Threaded Flange
Blind Flange
Lap Joint Flange
Orifice Flange

To look for a short circuit, check for any abnormal connections or damaged wires causing a direct path for current flow.
Inspect all wiring and connections for signs of damage or wear
Use a multimeter to test for continuity and resistance in the circuit
Look for any burnt or melted components indicating a short circuit
Check for any loose connections or exposed wires that could be causing a short circuit
Casting solidification time is the duration it takes for molten metal to solidify in a casting process.
Casting solidification time depends on factors like material type, mold temperature, and casting geometry.
Higher pouring temperatures generally result in shorter solidification times.
Thicker sections of the casting will take longer to solidify compared to thinner sections.
Aluminum alloys typically have shorter solidif
Casting design considerations include material selection, part geometry, draft angles, surface finish, and shrinkage.
Material selection is crucial for the desired properties and performance of the final part.
Part geometry should be designed to minimize stress concentrations and ensure proper flow of molten metal.
Draft angles are necessary for easy removal of the part from the mold.
Surface finish requirements should be ...

Motor converts electrical energy into mechanical energy. It starts by applying a voltage to the motor windings.
Motor converts electrical energy into mechanical energy
Motor starts by applying a voltage to the motor windings
Motor working principle involves the interaction between magnetic fields and current flow
Different types of motors include DC motors, AC motors, and stepper motors
Pneumatic symbols represent components used in pneumatic systems, with arrows indicating the direction of air flow.
Pneumatic symbols are used to represent components like valves, cylinders, and pumps in pneumatic systems.
Arrows in the symbols indicate the direction of air flow through the component.
Common symbols include a circle for a valve, a rectangle for a cylinder, and a triangle for a pump.
Understanding these sym...

I applied via Naukri.com and was interviewed in Jul 2024. There was 1 interview round.
A turbocharger is a device that increases the efficiency and power output of an internal combustion engine by forcing extra air into the combustion chamber.
Turbochargers use exhaust gases to spin a turbine, which in turn drives a compressor to force more air into the engine.
This extra air allows more fuel to be burned, resulting in increased power output without the need for a larger engine.
Turbochargers are commonly u...
The gases in engine exhaust typically include carbon dioxide, carbon monoxide, nitrogen oxides, hydrocarbons, and particulate matter.
Carbon dioxide (CO2) is a greenhouse gas produced during combustion.
Carbon monoxide (CO) is a toxic gas formed by incomplete combustion.
Nitrogen oxides (NOx) are pollutants that contribute to smog and acid rain.
Hydrocarbons are unburned fuel molecules that can react in the atmosphere to f...
