DEF system is responsible for reducing harmful emissions in diesel engines by injecting a urea-based solution into the exhaust stream.
DEF system helps convert harmful nitrogen oxides (NOx) into harmless nitrogen and water vapor.
The urea-based solution is stored in a separate tank and injected into the exhaust stream before it reaches the selective catalytic reduction (SCR) catalyst.
Proper maintenance of the DEF system ...
The temperatures at the exhaust Air Treatment System (ATS) vary depending on the specific system and operating conditions.
The temperatures at the exhaust ATS can range from 200 to 800 degrees Celsius, depending on the type of system and the treatment process being carried out.
Higher temperatures are often required for processes such as thermal oxidation, while lower temperatures may be sufficient for processes like ads...

I applied via Naukri.com and was interviewed before Nov 2022. There were 2 interview rounds.
Electronic components work based on Ohm's Law, which relates voltage, current, and resistance.
Ohm's Law states that V = I * R, where V is voltage, I is current, and R is resistance.
Electronic components such as resistors, capacitors, and inductors follow Ohm's Law in their operation.
Understanding Ohm's Law helps in designing and troubleshooting electronic circuits.
For example, in a circuit with a 12V battery and a 4 oh...

I applied via Referral and was interviewed in Sep 2020. There were 4 interview rounds.
IGBT stands for Insulated Gate Bipolar Transistor. It is a power semiconductor device used for switching and amplifying electrical signals.
IGBT combines the advantages of both MOSFET and bipolar junction transistor.
It has a high input impedance like a MOSFET and a low on-state voltage drop like a bipolar transistor.
IGBTs are commonly used in applications such as motor drives, power supplies, and renewable energy system...
To test a battery, you can use a multimeter to measure voltage, perform a load test, and check for any physical damage or leaks.
Use a multimeter to measure the voltage of the battery. A healthy battery should have a voltage close to its rated voltage.
Perform a load test by connecting a known load to the battery and monitoring its voltage drop. A healthy battery should maintain a stable voltage.
Inspect the battery for a...
A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a type of transistor used for amplifying or switching electronic signals.
MOSFET is a three-terminal device that consists of a source, a drain, and a gate.
It is made up of a metal gate electrode separated from the semiconductor channel by a thin insulating layer of oxide.
MOSFETs are widely used in various electronic devices such as computers, smartphones, a...
