2.5.2.7. Management of the mechanism of change of phases of a gazoraspredeleniye

Management of the mechanism of change of phases of a gazoraspredeleniye of Mazda 3 (GG) is in essence taken from the modern MX-5 (NB) model, except for a mode of cleaning and a mode of the maximum delay for coordination with vehicle characteristics.
Conditions of a mode of cleaning following:
– reduction of frequency of rotation of the engine when closing by a butterfly valve;
– frequency of rotation of the engine – between 2250 mines-1 and 3500 mines-1;
– the temperature of cooling liquid – is higher than 80 °C the maximum delay;
Besides, any of the following conditions should be executed:
– start;
– frequency of rotation of the engine – is lower than 970 mines-1;
– the temperature of cooling liquid – is lower than 18 °C;
– the target moment of opening or valve closing – 0;
– torque reduction.
