NGK provides tips on broadband sensors

currently, the attention of vehicle manufacturers is focused on reducing pollutant emissions and energy efficiency. within this context, in the last years, we had a great technological evolution in national engines. The lambda probe is one of the components that has received significant improvement., becoming of the linear type, that many mechanics know as a broadband probe and its function is to identify the correct air/fuel ratio, providing more accurate adjustment of the electronic injection system. But, and at repair time? How is it possible to review? What is the main sign of failure? Check out NGK's tips, world reference in the automotive sector, to check and replace the product correctly. The component only equipped premium segment vehicles, although, now, is standard on most popular models, starting with Volkswagen up! which uses the EA211 turbo engine line, extending to other vehicle applications. According to Hiromori Mori, NGK Technical Assistance Consultant, a characteristic of this sensor is that it works associated with a controller chip that is normally inside the injection module. "Thus, it is recommended to use the same brand as the original probe. Check the correct application in the NGKNTK table”, Mori explains. In this injection system, the operation is a little different from conventional systems. According to the injection module work strategy (rich mixture, estequiométrica, poor, homogeneous or stratified). The system defines an ideal lambda and compares it with the lambda read by the probe, there is usually a margin of tolerance that is usually small.. A point of attention is when the vehicle is calibrated for a non-Brazilian fuel. How Local Fuel Contains Ethanol, sometimes it gets too close to the tolerance limit without the vehicle having any problem. Diagnosis of this system is much more complex.. when there is a breakdown, it is necessary to make a complete diagnosis of the injection system and follow the test procedures stipulated by the vehicle manufacturer, normally probe diagnosis is by exclusion. In order to facilitate diagnosis and testing, some diagnostic equipment manufacturers, known as scanners are already working to make testing procedures for these systems available on their platforms.. Where to find? Commercially known as linear sensor or A/F sensor (air/fuel, in Portuguese), the original product can be purchased by the customer using a code available in the NGK do Brasil application catalog.
