Engine heating is caused by the combustion process generating heat that is not dissipated quickly enough.
Combustion process generates heat
Heat is not dissipated quickly enough
Can be caused by low coolant levels, malfunctioning thermostat, or clogged radiator
Can lead to engine damage if not addressed
BS4 and BS6 are emission norms set by the government to regulate the amount of pollutants emitted by vehicles.
BS4 stands for Bharat Stage 4 and BS6 stands for Bharat Stage 6.
BS6 is the latest emission standard set by the government, which is more stringent than BS4.
BS6 compliant vehicles emit lower levels of pollutants such as nitrogen oxides, carbon monoxide, hydrocarbons, and particulate matter compared to BS4 vehicl...
SCR system is a technology used in diesel engines to reduce nitrogen oxide emissions.
SCR stands for Selective Catalytic Reduction
It uses a catalyst to convert harmful nitrogen oxides into harmless nitrogen and water
Requires a urea solution to be injected into the exhaust system
Commonly used in heavy-duty vehicles and industrial equipment

The list count of a vernier caliper typically includes the main scale and the vernier scale.
The list count of a vernier caliper is usually 2, consisting of the main scale and the vernier scale.
The main scale is typically graduated in millimeters or inches, while the vernier scale allows for more precise measurements.
The vernier scale has divisions that are slightly smaller than those on the main scale, enabling measure...
I study drawing by practicing regularly, taking classes, studying anatomy, observing real life objects, and seeking feedback from others.
Practice regularly to improve skills and develop a personal style
Take drawing classes to learn new techniques and receive guidance from instructors
Study anatomy to understand the structure of the human body and improve figure drawing
Observe real life objects to improve observational s...
The question is asking for the name of a part used in vehicle servicing.
Provide the specific name of the part used in vehicle servicing
Examples: oil filter, spark plug, air filter
Four stroke diesel and petrol engines operate on the principle of internal combustion, but with different fuel types.
Both diesel and petrol engines are internal combustion engines that convert chemical energy into mechanical energy.
In a four stroke diesel engine, the four strokes are intake, compression, power, and exhaust. Diesel fuel is ignited by compression alone.
In a four stroke petrol engine, the four strokes are...
Types of gear boxes include manual, automatic, CVT, DCT, and sequential.
Manual gear box requires the driver to manually shift gears using a clutch pedal.
Automatic gear box shifts gears automatically without the need for manual input.
CVT (Continuously Variable Transmission) provides seamless gear shifts without distinct gear ratios.
DCT (Dual Clutch Transmission) combines the efficiency of manual transmission with the co...
Parts of chassis frame include rails, cross members, and brackets.

I applied via Walk-in and was interviewed in Feb 2022. There was 1 interview round.
Two stroke engines have a power stroke every revolution, while four stroke engines have a power stroke every other revolution.
Two stroke engines have a simpler design and are lighter than four stroke engines.
Four stroke engines are more fuel efficient and produce less emissions than two stroke engines.
Examples of two stroke engines include chainsaws and dirt bikes, while examples of four stroke engines include cars and...
Petrol engines use spark ignition while diesel engines use compression ignition.
Petrol engines have higher RPMs and are more suitable for high-speed driving.
Diesel engines have higher torque and are more fuel-efficient.
Petrol engines are lighter and quieter while diesel engines are heavier and noisier.
Petrol engines emit more CO2 while diesel engines emit more NOx and particulate matter.
Examples of petrol engines: Hond...
EGR system reduces NOx emissions by recirculating a portion of exhaust gas back into the engine intake.
EGR valve controls the flow of exhaust gas into the intake manifold
Recirculated exhaust gas reduces combustion temperature and lowers NOx emissions
EGR system can cause carbon buildup in the intake manifold and reduce engine performance
EGR system is commonly used in diesel engines
EGR system can be disabled or removed f...
