INTERNAL COMBUSTION ENGINE AND CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2013/179935
Kind Code:
A1
Abstract:
In order to avoid a surge state of the compressor (5b) of a turbocharger (5), an ECU (20) is configured to be provided with a surge avoidance means (process) which, during vehicle deceleration, determines whether or not the compressor (5b) of the turbocharger (5) enters a surge state; if the compressor (5b) is determined to enter a surge state, then, as surge avoidance control, the surge avoidance means acquires a first target opening degree (TAn) of the nozzle vane (5c) of a turbine (5a) of the turbocharger (5) based on the driving state and a first opening degree map (M1); if the first target opening degree (TAn) is less than a pre-set surge avoidance first target opening degree (TAx), then the surge avoidance means controls the nozzle vane (5c) to the surge avoidance first target opening degree (TAx), and if the first target opening degree (TAn) is greater than or equal to the surge avoidance first target opening degree (TAx), controls the nozzle vane (5c) to the first target opening degree (TAn).
