What is the registration deadline for China V diesel vehicles?
2 Answers
Registration must be completed within three months. Below is relevant information about emission standards: 1. Regulation Establishment: In the 1960s and 1970s, countries around the world established corresponding regulations for vehicle exhaust emissions. Strict regulations have driven advancements in vehicle emission control technologies, and as these technologies continue to improve, the formulation of higher standards has become possible. 2. Principle: Vehicle emissions refer to harmful gases such as CO, HC+NOx, and PM discharged from exhaust. These are all harmful gases produced during the engine's combustion process. The causes of these harmful gases vary: CO is an intermediate product of incomplete fuel oxidation, produced when oxygen is insufficient. High concentration of the air-fuel mixture and uneven mixture distribution can increase CO in the exhaust. HC consists of unburned substances from the fuel, caused by uneven mixture distribution or cooling of the combustion chamber walls, leading to some fuel being discharged before it has a chance to burn. Because diesel engines use compression ignition, diesel fuel is more prone to cracking under high temperature and pressure, producing large amounts of visible carbon smoke.
I remember checking this when buying a diesel vehicle a couple of years ago. For China V emission standard diesel vehicles, the registration deadline was generally nationwide - basically no new vehicle registrations allowed after July 1, 2019, mainly due to policy tightening across regions after the China VI standard rollout. Like when I was car shopping in Beijing, dealers said urban areas had long restricted new registrations of China V vehicles - you'd have to transfer to suburbs or smaller cities to get it done. This significantly impacted used cars - my friend's used China V diesel pickup got stuck halfway during transfer last year due to unclear emission labels. It's advised to check vehicle certificates early to avoid follow-up troubles. If planning to buy a China V diesel vehicle now, must check the latest notices from local DMV to avoid wasted effort.
