It would lead to reduction of the engine emissions every year sharply.
Thirdly, considering there are several hundreds of petrol stations in a city, lower inspection rate can reduce the load of data transmission and the server calculation, making the whole inspection system more efficient. (3)Backend server: When the RFID reader receives information from a tag, the way of data transmission to the backend server may use wireless telecommunication technology such as GPRS or 3G.
After forwarding to the backend server through 3G transmission, the lambda signal is interpreted as the real λ value according to some predefined calibration data for checking any failed cases [7].

Since engines were not provided with any on-board system for monitoring its vibrations and no previous amendments were made to technical objects of that type, the following points of preparation were indispensable:
- the execution of the kinematic analyses of the engine under tests to identify its characteristic frequencies that could have occurred in the spectrum of the vibroacoustic signal;
- the acquisition (from engineering and operation documentation as well as from direct contacts with the engine manufacturer) and analysis of all available information related to vibration measurements already carried out by the manufacturer, measurement points, current and maximum allowed vibration levels;
- the development and calibration of necessary instruments suitable for the application of measuring vibrations in individual data recording paths;
- the execution of measurements themselves with the further analyses of variations demonstrated by the vibroacoustic signal.
The second rotor in embedded into a slow-speed turbine that transmits torque, via a reduction gear, to the airscrew shaft the rpm of which is reduced to the limits that enable the smooth operation of the airscrew.

A set of components used for making up measuring paths for engine vibrations (data processing and analysis) The assumption made was to measure vibration accelerations within the bandwidth from 2 [Hz] to 10 [kHz] with the amplification factor that guaranteed the maximum level of these accelerations up to 100 [mm2/s].

If we could combine the biogas with sewage, it would play a significant role in the work of energy saving and emission reduction.
In this context, we can show locations, factors and sizes of exergy losses clearly with the exergy analysis of system or process, finding out what is the real energy loss, looking for the methods of energy conservation, so that we will get reliable data in improving system efficiency [9-12].
Based on the above data, the pressure-enthalpy diagram is given by fig. 2.
The data are as table II.
