The latest technical state of the on-board exhaust emissions measurement system is described. The capability of the system of measuring the low emissions down-stream a catalyst under real-time conditions is pointed out. With a number of vehicles the efficiency of closed-loop catalysts was investitated. The test results show that also under real traffic conditions the mass emission levels of the regulated exhaust gas components are very well below the standards.
