Military Tracked Diesel Engine with Boost Control Device

摘要

The utility model relates to mechanical engineering, in particular to engine building, and can be used to improve the efficiency of a turbocharger of a diesel engine of military tracked vehicles.;The technical result of the proposed utility model is to increase the throttle response of a diesel engine with a gas turbine supercharging while maintaining acceptable parameters of the overall power of the power plant.;The technical result of the proposed utility model is achieved by the fact that in a diesel engine of a military tracked vehicle with a boost control device containing inlet and outlet manifolds, a turbine, a compressor driven by it, an air filter connected through an air duct to a compressor, a bypass valve control unit, according to the utility model, two bypass valves are installed on the intake manifold, one of which redirects the air compressed by the compressor through the pipeline connecting the compressor discharge pipe with the exhaust manifold to the inlet of the turbine nozzle apparatus, and the second supplies the engine with air through the pipeline connecting the intake manifold with the air filter, the wastegate control unit is electrically connected to the accelerator pedal position sensor and the crankshaft speed sensor.;In comparison with the prototype, the proposed technical solution allows to increase the throttle response of a diesel engine with a gas turbine supercharging, and, as a consequence, to improve the main indicators of the mobility of a military tracked vehicle, while maintaining acceptable parameters of the overall power of the power plant.
