Abstract

The disclosure of the invention belongs to the technical field of exhaust gas turbocharging, and specifically relates to an exhaust gas turbocharging control system and a control method thereof, including: an intake manifold sensor assembly, a sensor assembly in a turbine, an engine speed sensor, a microprocessor, a turbine Start-stop circuit, the turbine start-stop circuit is connected to the output end of the microprocessor, the specific control steps of the control method of the exhaust gas turbocharging control system are as follows: S1: monitoring the situation in the intake manifold, the turbine and the engine speed , S2: judge whether to start the turbo according to the monitoring data results, S3: start the turbo, and use the pressure and temperature values ​​in the intake manifold, the pressure and temperature values ​​in the turbo, and the engine speed to determine whether the turbo system is turned on Based on the basis, the turbocharging system can be turned on in a suitable environment to ensure the service life and improve its working efficiency; reduce misjudgments and ensure driving safety to a certain extent.

Description

technical field [0001] The invention relates to the technical field of exhaust gas turbocharging, in particular to an exhaust gas turbocharging control system and a control method thereof. Background technique [0002] The maximum power that the engine can emit is limited by the fuel that can be burned in the cylinder, and the amount of fuel is limited by the amount of air that can be absorbed by the cylinder per cycle. If the air is compressed before entering the cylinder to increase its density, the same cylinder working volume can accommodate more fresh charges, so that more fuel can be supplied and greater output power can be obtained. [0003] Exhaust gas turbocharging is a method of using the exhaust energy of an internal combustion engine to drive an exhaust turbocharger to achieve supercharging of an internal combustion engine. Exhaust gas turbocharger (referred to as turbocharger) consists of two main components: turbine (see turbine) and compressor (see compressor...
