208. 触媒コンバーター
触媒コンバーターは、車両の排気系統に装備される排出ガス制御装置です。化学反応によって有害な排気汚染物質を、より有害性の低い物質へ変換してから大気へ放出します。
エンジンとシステムにより、一酸化炭素、未燃焼炭化水素、窒素酸化物などを低減します。効果的に作動するには適切な温度が必要で、汚染、過熱、エンジン故障で損傷することがあります。
Is the catalytic converter checked during technical inspection in Belgium?
Yes. The vehicle's emissions-control equipment and exhaust emissions form part of roadworthiness inspection. A catalytic converter that is missing, modified or obviously defective can therefore cause an inspection problem.
Can you remove a catalytic converter from a vehicle in Belgium?
No. Where a catalytic converter forms part of the vehicle's required emissions-control system, it must remain present and functional. Removing or improperly modifying required emissions equipment can make the vehicle non-compliant.
Can a faulty catalytic converter cause excessive emissions?
Yes. A catalytic converter that no longer works correctly may fail to reduce exhaust pollutants sufficiently. This can lead to excessive emissions and an unfavourable result during the applicable emissions test.
