Today’s computerised engine control systems rely on inputs from a variety of sensors to regulate engine performance, emissions and other important functions. The sensors must provide accurate ...

This Design Idea describes a method by which you can detect and assess air or liquid fluid flow using an externally heated semiconductor diode. Airflow across the heated diode reduces its temperature, ...

Among the many methods available for air flow detection, self-heated thermal flow sensors are simple, cheap, rugged, and sensitive. They rely on the relationship between airspeed (AF) and thermal ...

There once was a time when something called a carburettor was the sole determinant of the air/fuel ratio in the internal combustion engine. No kidding. Ask the most senior member of your staff. He has ...
