Organization of the Six-Cylinder Tractor Diesel Working Process

The purpose of the work is organization six-cylinder diesel engines (with a power 116 and 156 kW) working process with exhaust gas recirculation. following systems components were used in experimental configuration engine: Common Rail BOSСH accumulator fuel injection system an pressure 140 MPa equipped electro-hydraulic injectors 7-hole nozzle 500 mm3 hydraulic flow; direct MOTORPAL pump maximum 100 MPa, AZPI five-hole injectors; two combustion chambers volumes 55 56 cm3 bowl diameters 67.5 mm; cylinder heads providing 3-4 swirl ratio for system, 3.5-4.5 mechanical system; recirculation rate was set by throttling before turbine using original design rotary valve. tests conducted at characteristic points NRSC cycle: minimum idle speed 800 rpm, torque 1600 rated 2100 rpm. It established: achievement emission standards kW engine possible use direct-acting equipment semi-open chamber; on - Low Cost type common supply open chamber.
