Apco Motors Interview Questions and Answers

The EGR system reduces emissions by recirculating exhaust gases back into the engine.

• The EGR valve controls the flow of exhaust gases into the intake manifold.

• The EGR system can become clogged with carbon buildup, causing engine performance issues.

• Proper maintenance and cleaning of the EGR system can improve fuel efficiency and reduce emissions.

• Some vehicles have EGR coolers to reduce the temperature of the recirculate...read more

The EGR system is an emission control technology that reduces nitrogen oxide emissions in diesel engines. BS6 technology is a stricter emission standard implemented in India.

• EGR system recirculates a portion of exhaust gases back into the engine to reduce NOx emissions

• BS6 technology requires vehicles to emit significantly lower levels of pollutants compared to the previous BS4 standard

• BS6 technology uses advanced engin...read more

Regeneration system is a process to clean the exhaust gases in diesel engines. BS6 is a stricter emission standard.

• Regeneration system uses a diesel particulate filter (DPF) to trap soot and ash particles.

• The DPF needs to be cleaned periodically through a process called regeneration.

• Regeneration can be passive (done automatically during normal driving) or active (done through a special process).

• BS6 emission standard is...read more
