How to Calculate Exhaust Emissions?

[MiaRose]

Actual exhaust emissions = Emission rate x Production days x Daily working hours x 10-3 or Actual exhaust emissions = Emission concentration x Benchmark flow rate x Production days x Daily working hours x 10-9. Below is relevant information about vehicle exhaust emissions: 1. Meaning of vehicle emission standards: Vehicle emission standards refer to harmful gases emitted from vehicle exhaust such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), PM (particulate matter, soot). In China, commonly used terms like Euro I and Euro II standards refer to emission directives issued by the EEC in those respective years. 2. Hazards of vehicle exhaust: When there are few vehicles, the atmosphere's self-purification capacity can still neutralize toxins emitted by vehicles. However, with the dramatic increase in vehicle numbers and traffic congestion becoming commonplace, excessive vehicle exhaust has become significantly harmful, seriously affecting human health.
