THE INERTIA COLLECTION SYSTEM UTILIZATION IN MODERN ENGINE RESEARCH AND SUPERVISION

Since the emission legislation was introduced during the nineteen sixties in the U.S., followed by other countries, there has been an intense discussion of how to check, in a simple way, the emission status of a car population. To carry out complete tests according to the federal test procedure or other legally based tests on a large population is economically impossible. Simplified chassiedynamometer test sequencies have not proved themselves worthwhile and idle tests give rather limited equivalents with the official test procedures. The simple and accurate short-test has been looked for not only by the administrators enabling them to enforce the Clean Air Act in a simple way, but also by the car industry in order to find safe and stable technical solutions to meet the legal limits. In the U.S. Clean Air Act, which is more or less a model for most other legislations, it is required that a short test should be in some agreement with the certification tests regarding the HC, CO and NOx emissions. Any short test, which in a simple way define those emissions, has not yet been introduced. The INertia COLLection method, which will be described more in detail here, should have realistic possibilities to comply with even rather high expectations on a short test.
