Simplified transient emissions testing system for gasoline vehicles

The simplified transient operating condition (VMAS) emission testing system for gasoline vehicles consists of a chassis dynamometer that simulates acceleration inertia and road resistance, a dedicated five-gas analyzer, a gas flow analyzer, and a computer control system.

It can analyze the emission quality of vehicles under road load conditions in real time, with results in g/km. This system is crucial for comprehensively evaluating vehicle emissions, estimating total vehicle emissions, and developing practical vehicle pollution control plans.

The system has computer networking capabilities, allowing it to connect to environmental protection department data processing centers, facilitating statistical analysis of emission data by government authorities.

The system is suitable for VMAS-based emission testing of in-use gasoli vehicle with dedicated gasoline engines and a maximum gross vehicle weight not exceeding 3500kg, using dual-idle conditions.
