ENGINE UNIT CONTROL METHOD (VERSIONS) Russian patent published in 2006 - IPC F02D41/02 

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: invention relates to methods of control of engine units. According to proposed method, maximum value of output value or output parameter of engine unit is set and if actual value exceeds maximum value, measured are taken in response. Maximum tolerable value is formed depending on position of accelerator pedal and, at least under one mode of operation, it is filtered with account of dynamic characteristics ion intake manifold of internal combustion engine. In process of filtration, delay unit is used making it possible to take into account delay time characteristic for intake manifold. According to second control method, maximum value of output value or output parameter of engine unit is set and, if actual value exceeds maximum value, corresponding measured are taken in response. Maximum tolerable value is continuously decreased depending on receding of at least one value characterizing definite mode of operation from maximum vale. According to third method, maximum value of output value or output parameter of engine unit is set and if actual value exceeds said maximum value, corresponding measures are taken in response. Said maximum value is determined depending on minimum degree of cylinder filling and/or maximum value is determined depending on some minimum value which, in case of additional requirement for increase of torque, is formed using value which depends on engine temperature.

EFFECT: provision of optimum results at control of engine unit.
