An experimental bench rig has been devised at Southwest Research Institute (SwRI) that uses engine-like conditions to accumulate intake valve deposits. There is no combustion, so the intake valve is heated by an induction heater. This arrangement allows independent control of such variables as manifold depression, speed, air and fuel flow rates, and most importantly, valve temperatures.
The primary objective of the bench test rig was to produce intake valve deposits in the laboratory capable of causing driveability problems without the expense of conducting lengthy automobile driving tests. SwRI accomplished this objective by determining in laboratory tests the combination of engine operating conditions (i.e., manifold vacuum, airflow, speed, injection timing, and valve temperature) that would produce the desired deposits.
