emissions reducing systems

what is the process that allows a DPF to clean itself out

• Restoration

• Regeneration

• Reconditioning

• Reclamation

What is the purpose of the precious metals in a catalytic converter

• to make it more expensive so car companies can charge more

• to make the cars more valuable to thieves

• to chemically react with the exhaust gases to convert some of them to less harmful gases

• to clean the air coming into the engine

what does an EGR valve do (multiple)

• increases combustion temperatures

• decrease combustion temperatures

• reduces the number of NOx particles within the reburned exhaust gases

• makes the engine run faster

when were DPF's made mandatory

• Euro 2

• Euro 3

• Euro 4

• Euro 5

where is the catalytic converter placed within the exhaust system

• front near the exhaust manifold

• middle of the car

• rear near the tailpipe

• in the bin because you get more power without them

what are the emissions that the government are trying to reduce

• Carbon monoxide

• Hydrocarbons

• Nitrogen oxides

• Oxygen

what cars have adblue as a emission regulation system

• petrol

• diesel

• electric

• hybrid

what does "EVAP" stand for

• Evaporative Emission Control System

• Evaporative emission cleanup system

• Emission from vehicles atmosphere protection

at around what temperature does a catalytic converter need to be to work properly

• 600C

• 1000C

• 3000C

• 20C

which of these are physical filters for the exhaust gases to pass through

• catalytic converter

• DPF

• GPF

• O2 sensors
