Is Nitrous Oxide Modification Illegal?
2 Answers
Nitrous oxide modification is not illegal. Here are the details: Reason: Vehicle owners do not need to apply for modification registration if the changes do not affect safety or license plate recognition, such as installing front and rear anti-collision devices on small and micro passenger vehicles, or adding windshields, water tanks, toolboxes, spare tire racks, etc. to freight vehicles. Introduction to Nitrous Oxide: The so-called nitrous oxide acceleration for car engines actually uses nitrous oxide (N2O), not nitrogen. Working Principle: The principle involves injecting nitrous oxide from an onboard cylinder into the working cylinders, increasing the oxygen content in the engine's intake air while also increasing the fuel injection volume from the fuel supply system. This temporarily boosts the engine's output power without altering the engine's structure.
As someone who frequently studies automotive modification regulations, I believe nitrous oxide (NOS) modifications are indeed illegal in most places. The NOS system uses nitrous oxide to instantly boost horsepower, which sounds exciting but carries significant legal risks. In China, the Road Traffic Safety Law strictly prohibits any unapproved modifications, including NOS systems, as they can cause engine knock or loss of control, endangering safety. Some U.S. states allow its use under specific conditions, but it must still comply with emissions standards. Illegal modifications may result in fines, penalty points, vehicle confiscation, or mandatory restoration to factory condition. I also recommend car owners prioritize legal alternatives, such as ECU upgrades or turbocharger installations, which are safer and more reliable. Ultimately, if you want to race, track days or professional circuits are the smarter choice to avoid trouble on public roads.
