Guys, just want to share the info from OBIT Engine Management System adopted in the latest car is using highly accurate sensors with the best signal coupling point, which enable to control engine with accuracy and delicately. It is for the purpose of more engine power output and less fuel . Here some example is introduced. At first, it is about the Adjustment of fuel . Fuel adjustment took place inside of engine ECU that calculates signals, such as airflow, a water temperature and r.p.m.signal, in the processing unit inside ECU, and the fuel is injected according to a situation. Respectively O2 sensor detects the mixed ratio of air and fuel of exhaust gas and the A/F signal is sent to ECU. Then this feed back signal adjusts the supply of fuel to the ideal value. Generally it is called feedback system or self study system. Or it is called Lambda control system that has two-control area, namely closed loop and open loop area. Almost all cars inclusive of Europe vehicle are contr...
