Additional elements are new costs, and what kind of businessman will voluntarily go for them!
But the law is the law, it will have to be implemented - and it is not as difficult as it seems at first glance.
We will deal with the new engine management system and the features of its diagnosis.
The controller located in the engine compartment does not suffer from water and dirt - its body is sealed.
For full-fledged “communication” with the latest MIKAS-10 controller, you need your own scanner. The software module for previous blocks is not suitable. Up to 70% of the capabilities of the new unit are intended for self-diagnosis of the control system. It has become “smarter”: it does not immediately respond to a random deviation of a parameter, but waits for the next failure, compares the data, analyzes it, and when the error is repeated, it will write its code into memory.
The previous controllers (MIKAS-5, MIKAS-7) were a weak help for the diagnostician - the parameters they recorded were not enough to search for many malfunctions. MIKAS-10 has non-volatile memory: this “black box” stores facts and engine operating time in critical conditions - for example, exceeding the permissible crankshaft speed or the allowed speed during the break-in period, exceeding the maximum coolant temperature, and an unacceptable decrease in the ignition timing due to low octane fuel detonation and other information that helps establish the causes of engine damage.
The new HFM62C19 DFID is not interchangeable with the previous Siemens-HFM62C11, and they have different electrical connectors, so the error is practically eliminated.
Modern DMRV is made using new technology, its measuring film is very sensitive, but at the same time not as tender, vulnerable as the previous sensors. Its thickness is 150 microns, three times more than that of other DMRVs, and is applied not to ceramics, but to glass, which is less polluted.
DPKV - the crankshaft position sensor is the same, but the modern controller makes wider use of the information received from it, comparing it with information from the camshaft position sensor, etc. It, for example, captures the misfires of flashes in the engine cylinders - and when their number exceeds the permissible, the “Check Engine” lamp flashes on the dashboard. Most often, candles, high-voltage wires, ignition coil are to blame. If the malfunction is not resolved, the controller will turn off the nozzle in this cylinder after a while, which will reduce harmful emissions into the atmosphere and protect the converter from overheating and destruction. At the same time, the temperature of the converter is controlled - it should not exceed 900 ° C. Based on the data on fuel consumption, the controller calculates the temperature of the exhaust gases - if it deviates from the norm, it changes the fuel supply so that the gas temperature is not excessive. Fuel consumption may increase slightly, but the converter will be saved. (The warning lamp in this case does not light up, but information will be recorded in the "black box".)
The speed sensor in the MIKAS-10 control system not only informs the driver about the speed of the car. Its signal is taken into account in the engine control algorithm. When braking it, the controller more precisely controls the idle speed controller. Comparing the speed of the car and the crankshaft speed, it “recognizes” the transmission in the gearbox. Recommended rotational speeds are recorded in the program for each transmission - when “twisting”, the controller sequentially disables the engine nozzles. MIKAS-10 also has an “anti-jerk” function: when trying to accelerate too sharply, the controller does not allow an unjustified “throw” of revolutions, makes acceleration smoother, and eliminates shock in the transmission.
