Reduce control system of diesel engine transient state operating mode smoke intensity

The utility model belongs to internal-combustion engine transient state operating mode emission control technique, concretely relates to reduce control system of diesel engine transient state operating mode smoke intensity and control method. It by engine, air cleaner, compressor, with coaxial continuous turbine, the intercooler that admits air of compressor, set up and press the sensor at epaxial high response speed sensor of output and high response torque sensor, the jar that sets up in the cylinder block, the automatically controlled unit of ECU, charge amplifier, the singlechip that is equipped with CA50 calculation program, the bent axle position sensor who sets up on the engine flywheel form, based on this system to smoke intensity and CA50 (the diesel oil burning bent axle corner that 50% mass fraction corresponded) are control objective, adopt three-section broken line loading tactics adjustment fuel delivery rate to realize the change of loading rate. Realize simultaneously reducing diesel engine transient state operating mode smoke intensity and improve the engine torque response, overcome both shortcomings that can not compromise of prior art.
