Concentrated power in a triple pack - the HELLA exhaust trio

In the wake of global warming, the question of how to deal with exhaust gases is becoming increasingly important. As a global player, HELLA has outstanding OE expertise in the independent aftermarket. And thus also has the right answer to lower emissions at high performance. In our HELLA product video, we explain how the products involved in the exhaust gas consumption of a vehicle work: Mass air flow sensor, exhaust gas recirculation valve and lambda sensor. And explain when replacement of these three products may be necessary. The HELLA exhaust trio enables optimum performance and low emissions.

How does the air mass sensor work?

How does the air mass sensor work?

The air mass sensor is located between the air filter housing and the intake manifold. It measures the intake air flow of the engine, which is crucial for the real-time adjustment of the air/fuel mixture. It also serves as a control gateway for the functionality of the EGR system. The air mass sensor therefore plays a decisive role in modern combustion engines and makes a significant contribution to the optimum performance and efficiency of the engine.

When does the air mass sensor need to be replaced?

Incorrect air flow and temperature values delivered by the sensor reading head could be one of the reasons. Among other effects, this can result in a loss of power, increased fuel consumption, bad driving experience and increased emissions. Driving with a defective mass air flow sensor can also have a negative effect on the reliability of other related emission and engine management components. Therefore, it is very important to recognise a faulty air mass sensor at an early stage and replace it with the best suitable product to the specific application. It is recommended not to clean a dirty mass air flow sensor, but to replace it for a reliable long-term result.
