Regeneration of zirconium oxygen sensor signal is made by analyzing the signals of mass airflow sensor (MAF) and fuel nozzle with their subsequent comparison with the table. Basic table is recorded by the manufacturer or during emulator self-learning (Fig. 2). Correction of fuel mixture can be made with the help of emulator features.
By agreement the emulators for titanium oxygen sensor with signal 0….5 Volts may be delivered.
It is possible to switch the emulation tables of oxygen sensor with external switch. It is necessary, for example, when going into high-power or economy mode, propane or petrol (for autogas system).
Regeneration of analogue signal is made according to the three-dimensional map. The table (map) contains voltage values at the emulator output, which are connected to rotation speed, injection time or airflow. This function may be used for MAF signal emulation of sensor even if it is absent. Such an approach allows to remove this sensor. Regeneration of MAF signal is made by converting MAP signal, which is installed is necessary (price of MAP sensor of Daewoo Lanos is around 25$).
SK-04 emulator is completed with the software, which allows to connect it to the computer, to read and record all parameters in real time, to read the fuel consumption, to make setting without engine stopping. The graphical output of data is provided. There is an opportunity to keep and record signal emulation tables (Fig. 1).
Due to the fact that there is a possibility to correct the tables, it is possible to correct the fuel mixture at different engine run modes.
The device can work with MAF, having with an analogue and pulse output.

Program of emulator of oxygen sensor and MAF may display (graphically) and save the following parameters in the file:
Rotation speed, injection time, MAF voltage (MAP readings is converted into relative amount of air), oxygen sensor voltage, instantaneous and overall fuel consumption.

This graph and table determine the ratio of fuel and air to emulate the oxygen sensor signal.
If MAP is used, its voltage is converted into relative airflow.
If MAF is used, the current amount of fuel is compared with MAF voltage.

Output signal is produced on the basis of:
1. Crankshaft rotation speed;
2. You can select one of the preferences:
а) Input voltage;
b) Estimated airflow (is calculated based on the rotation speed and readings of external MAP sensor);
c) Fuelinjectiontime.

Output signal is produced on the basis of the estimated airflow or input emulator voltage.
Also it is possible to indicate to produce signal on the basis of fuel consumption.

What does the emulator allow?
· Allows to remove zirconium or titanium oxygen sensor;
· Allows to replace regular MAF sensor with cheap MAP sensor (MAP - 25$);
· Availability of fuel economy or power increase under due setting of the fuel mixture;
· Receipt as per the table of any signal with level of 0 to 5V, which may be used for almost any purposes.
