Can a Vehicle Pass Inspection Without a Catalytic Converter?
2 Answers
The impact of not having a catalytic converter on a vehicle includes: the engine emission warning light on the combination instrument panel will illuminate, and the vehicle's exhaust emissions will severely exceed standards. Driving on the road may result in being caught for violations, facing fines and other penalties. If the vehicle reaches the annual inspection period, it will definitely fail the on-line inspection. Relevant information about the catalytic converter is as follows: 1. Introduction: The catalytic converter is the most important external purification device installed in the vehicle's exhaust system. It converts harmful gases such as CO, HC, and NOx emitted by the vehicle's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction. 2. Working Principle: When high-temperature vehicle exhaust passes through the purification device, the purifying agent in the catalytic converter enhances the activity of the three gases—CO, HC, and NOx—promoting certain oxidation-reduction chemical reactions.
As an experienced hand who often helps neighbors check their cars, I believe that failing the annual inspection without a catalytic converter is a certainty. Nowadays, emission testing during annual inspections is very strict. The catalytic converter is a crucial component for treating harmful gases in the exhaust, such as carbon monoxide and hydrocarbons. Without it, the exhaust emissions will exceed the limits, and the testing machine will immediately detect it. Not only will you fail the inspection, but you may also face fines from traffic police or even have your car impounded. I remember a friend last year who tried to save money by not installing a catalytic converter, and the inspection station flagged it immediately, costing him double to fix it later. Just go to a repair shop and buy a new catalytic converter to install. Aftermarket ones can be done for a few hundred yuan, while OEM ones are more expensive but more durable. Driving without it usually leads to increased engine carbon buildup and higher fuel consumption, which is more costly in the long run.
