Advantages of Cooling Airflow Control Devices Using by Internal Combustion Engines 2001-01-1703

The cooling airflow control devices are news in automotive engineering. The authors of this paper have achieved some patents in this field, with car engines application. The purpose was to improve engine performances. In the paper the construction of the cooling airflow control, as they are patented, tests made on some cars and corresponding experimental date are presented. Analyzing the experimental results an improving of combustion process could be observed. The cooling airflow devices are patented in mechanical and electronic form, and a prototype of mechanical device was made. The efficiency of these devices is significant below 5°C environmental temperature.
