An O2 or lambda simulator is used to send a simulated oxygen/lambda sensor signal to an engine ECU running in closed loop mode. O2 sensors generate voltages between 0.9V (rich) and 0.1V (lean). A ...

Compared with the LSF4.2, it takes half as much time to reach control mode following engine start. This significantly reduces the amount of time in which the engine’s emissions are uncontrolled.

Don't let failing oxygen sensors compromise your engine's performance. O2 sensors are critical to emissions control on your car, SUV or truck. As the name implies, the O2 sensor (also called an ...

This repository contains all code, pcb design, and verification scripts performed for the Lambda Oxygen Sensor Interface. This device uses a Bosch LSU 4.9 paired with a Bosch CJ125 to measure the ...

Alina has been enthusiastic about vehicles her entire life, and even from an early age found herself itching to get behind the wheel. Through high school and college, she could be found reading ...

With fuel prices rising, the need for accurate air/fuel mixture monitoring is more important than ever. The engine computer needs to know what the fuel mixture is with a high degree of precision so it ...

The operation of biomass treatment devices such as gasifiers is based on the control of key parameters that play an important role in product formation. These include: temperature, excess oxygen, ...

As performance enthusiasts and racers work with more sophisticated tuning tools—especially those designed for EFI engines—there's a growing debate on whether to use air-fuel ratio or Lambda in the ...
