ELECTROMAGNETIC NOZZLE CONTROL DEVICE

FIELD: mechanical engineering; diesel engines. SUBSTANCE: invention relates to electronic control of delivery of liquid or gaseous fuel into cylinders of diesel engine. Proposed device contains supply source, four active electronic switches, pulse generator whose input is coupled with input of pulse generator with two control inputs one of which is connected with load current pickup and other with on-off time ratio setter. Output of pulse generator is coupled with input of first active switch, output of pulse generator with control inputs is coupled with input of second active switch. It has also three electronic switches, single square pulse generator, reservoir capacitor and inverting unit. Input of single pulse generator is coupled with input of pulse generator, and output is coupled with input of third active switch and input of inverting unit whose output is connected with input of fourth active switch. Third active switch is connected in parallel with first electronic switch. reservoir capacitor couples outputs of second and fourth active switches, and third electronic switch whose output is connected with supply source, is connected in parallel with fourth active switch. EFFECT: provision of quick response owing to formation of demagnetizing current pulse. 2 cl, 6 dwg
