When the turbocharger spins rapidly due to high exhaust gas pressure, the wastegate valve opens, allowing some exhaust gas to bypass the turbine wheel. By adjusting the opening and closing of the wastegate valve, the system ensures the desired boost pressure is achieved and maintained.
Excess exhaust gas is redirected to the exhaust system, preventing excessive pressure buildup in the intake manifold and the engine. The wastegate actuator controls the wastegate valve's movement based on signals received from the engine management system.
Proper functioning of the wastegate turbocharger is essential for maintaining optimal engine performance, fuel efficiency, and preventing potential damage caused by excessive boost pressure.
