There are other possibilities leading to a malfunction of the pneumatic circuit: It would help if you then replaced the solenoid valve. Malfunctions in the pneumatic circuitĭo you notice that the turbocharger stops and that the engine management computer limits the speed? It is undoubtedly because the core no longer performs its air valve function. Solenoid valve malfunctions can be electrical or pneumatic. What are the malfunctions of the turbocharger solenoid valve? Thus, in the event of accidental vacuum suppression, the wastegate opens, neutralizing the turbocharger. When there is a vacuum in the system, the valve is closed, and the turbo is driven. The air valve, connected on one side to a vacuum source (vacuum pump, also used for braking assistance), controls the wastegate via a rubber tube. As it moves, it opens the pneumatic circuit and controls the wastegate. The engine ECU sends an electrical impulse to an integrated coil creating an electromagnetic field that activates a core (or spool). The solenoid valve is a plastic block consisting of an electromagnetic coil and an air valve. To do this, it is electrically controlled by the engine control unit, which manages the turbo pressure regulation. The role of the turbocharger solenoid valve is to control the wastegate pneumatically (with a vacuum). What is the role of the turbocharger solenoid valve? When the pressure reaches its maximum value, this valve diverts the exhaust gases to no longer drive the turbo, thus lowering the intake pressure. The pressure is regulated by a bypass valve (called a wastegate) integrated into the turbo. It is necessary to limit this air intake pressure to avoid the risk of turbo failure caused by excessive rotation speed.
The turbocharger compresses the intake air for better filling and combustion of the engine. It is placed at the engine outlet, driven in rotation using exhaust gas flow from the engine’s combustion.
The turbocharger is intended, like the positive displacement compressor, to increase the engine’s specific power and, therefore, the vehicle’s power. Turbocharger solenoid valve: what is the purpose of the turbocharger? Thus, the displacement is smaller (with the appearance of 3-cylinder engines), and the power/liter ratio becomes better, allowing a reduction in CO2 emissions. If you like to tinker with your car, it’s best to know how the solenoid valve works.ĭownsizing allows the specific power of a displacement (power per 1 liter (1,000 cm³) to increase from 50 horsepower for older generations of engines to 130 horsepower. The current trend of engine manufacturers to exploit an engine’s maximum performance makes the turbocharger a crucial element for a vehicle’s downsizing the turbocharger solenoid valve controls it.
