[0048] As a result of increased / modified by the microcontroller signals the motor power is increased. Below examples of modifications by the microcontroller M input signals in order to issue control signals modified to increase engine power.

Example 1

[0049] We consider only the fuel pressure.

[0050] We measure the fuel pressure signal 3.It is in the range of 0V to 5V. It is processed by the microcontroller M and then passed to the engine controller S - modified signal 10. After crossing the threshold of 2V begin to modify the signal by reducing its value, respectively 0%, 10%, 20% and 30% depending on the selected mode. After crossing the fuel pressure signal 4V stop editing it.

Example 2

[0051] We only consider the airflow.

[0052] We measure the fuel pressure signal 3 and the air flow first It is processed by the microcontroller M and then passed to the engine controller S - modified signal 10.Depending on the type of flow meter is an analog signal range from 0V to 5V or Digital to 15 kHz. After crossing the threshold of 100 kg / h of air masses begin to modify the fuel pressure signal by reducing its value, respectively 0%, 10%, 20% and 30% depending on the selected mode. After crossing the air mass 500 kg / h stop modify the pressure signal.

Example3

[0053] We only consider the fuel pressure, boost pressure and air flow.

[0054] We measure the fuel pressure signal 3,the boost pressure signal 2 and air flow. They are processed by the microcontroller M and then passed to the engine controller S - modified signals 8, 9 and 10. Depending on the type of flow meter is an analog signal range from 0V to 5V or Digital to 15 kHz. After crossing the threshold of 100 kg / h air mass signals begin to modify the fuel pressure, boost pressure and the amount of flowed air o reducing their value by 0%, 10%, 20% and 30% depending on the selected mode. After crossing the air mass 500 kg / h stop signals modify all signals to protect against motor overload.

Example 4

[0055] We only consider the fuel pressure and engine coolant temperature.

[0056] We measure the fuel pressure signal 3 and the signal from thermal protection 21. Fuel pressure signal is in the range of 0V to 5V. It is processed by the microcontroller M and then passed to the engine controller S - modified signal 10.After crossing the threshold of 2V begin to modify the signal by reducing its value, respectively 0%, 10%, 20% and 30% depending on the selected mode. Modification occurs only when the coolant temperature is greater than 60°C. After crossing the fuel pressure signal 4V stop editing it.

Example 5

[0057] We only consider the fuel pressure and exhaust gas temperature.

[0058] We measure the fuel pressure signal 3 and the temperature of the exhaust gases 4.Fuel pressure signal is in the range of 0V to 5V. It is processed by the microcontroller M and then passed to the engine controller S - modified signal 10.After crossing the threshold of 2V begin to modify the signal by reducing its value, respectively 0%, 10%, 20% and 30% depending on the selected mode. Modification occurs only when the temperature of the exhaust gas is less than 750°C. After crossing the fuel pressure signal 4V stop editing it.

Example 6

[0059] We only consider only the work of the injectors.

[0060] We take the signal from the injectors 7 and used to calculate the engine speed. It is processed by the microcontroller M and then passed to the injectors - signal 15.After crossing the threshold of 2000 rev / min beginning to modify the control signals to the injectors by increasing the time of opening, respectively 0%, 10%, 20% and 30% depending on the selected mode. If you exceed 4500 rev / min engine stop modify them.

[0061] If you're working on more modified signals is at least three, it is important to ensuring that the ratio of air to fuel was optimal for the diesel engine (ratio from 12.5: 1 to 14,7:1).

[0062] On the diagram of Fig.3 shows a program installed on device BOX. Figure 4 shows interaction on the supervisory program, program to maintance box, and satellite navigation.

[0063] The programs allow viewing and measurement of modified signals indicate the percentage change in the signal modification and allow you to change modes of operation:

Mode 0 - no modification of

Mode 1-modification values of all signals up to +10%,

Mode 2 - a modification of the values of all signals up to +20%

Mode 3 - modify the values of all signals up to +30%

[0064] The method of protecting the engine from overheating during tuning is that it is preferably measured periodically every 1 second by at least one temperature sensor and the temperature of engine exhaust gas temperature, and so received signals to be transmitted to the central unit J, and if the temperature exceeds the temperature threshold of 800 °C for engine temperature and 650°C for the temperature of exhaust gas, the CPU J temporarily blocks the possibility of hardware tuning of the vehicle until the engine cool below the temperature threshold to prevent mechanical damage when the car too long and intensive tuning engine parameters.

[0065] The central unit J is a microprocessor, microcontroller, engine controller or computer.

[0066] Unit J realizes how in the form of a computer program, taking a signal engine coolant temperature preferably 60°C from the engine controller S and compares it with the maximum temperature, and then if the value exceeds the maximum permissible temperature of the microprocessor stops and blocks the action of hardware tuning until the temperature drops below the maximum allowable temperature.

[0067] As shown in Fig.5 and Fig.6 pressure and temperature gases in the exhaust system simulates the use of the device BOX of the invention. This is done to the engine with diesel particulate filter removed. Simulation is done solely for the proper operation of the engine driver. The system measures the air mass drawn in by the engine through at least one meter, and measures the temperature of exhaust gases through the flue gas temperature sensor and check the operation of the injector I. The resulting data transmitted to the microprocessor M of device BOX, the microprocessor M determines the exhaust gas temperature correction factor based on the time of the injector I. For running the injector I increases the exhaust gas temperature correction factor Tk-time to the maximum limit set equal to 2, and for not acting injector I reduces the exhaust gas temperature correction factor Tk-time to the minimum limit set equal to 1 sets the correction factor gas pressure Pk on the basis of elapsed time counter, or signal the distance traveled and the exhaust gas temperature, and for temperatures lower than the threshold is increased exhaust pressure correction factor to a fixed boundary Pk maximum 1.2 and a temperature greater than the threshold is reduced exhaust pressure correction factor Pk to set a minimum limit of the first thus obtained simulated flue gas temperature increased compared to the actual exhaust gas temperature in the exhaust system. The microprocessor M calculates the pressure and temperature exhaust gases in the exhaust system, which gives signals in the form of temperature and pressure signal to the engine controller S.

[0068] The temperature is calculated using the formula: Twyj = Twej * Tk
Where: Twej - inlet temperature measured in the exhaust gas temperature sensor
Tk - correction factor

[0069] Tk exhaust gas correction factor is in the range of 1 to 2.

[0070] Pressure is calculated by the formula: Pwyj = P (air mass, temperature) * Pk.
Where: P - the function calculates the pressure in the exhaust system
Pk - correction factor

[0071] Pk gas correction factor is in the range of 1 to 1.2.

[0072] The threshold temperature is 600°C.
