I have a different idea on idling from the arrogant I-know-everything-and-I-don't-want-other-opinions Nutrino. Final verdict first: According to a real expert from Saturn, there's no ill effect from idling for a long time, at least for the health of a car. The eexcessive stress that someone was talking about is caused by a gear-driven distributor shaking apart at idle. This could happen if the gears had too much lash. Most cars today have fully electonic designs with no distributor. Those that still have distributors use better designs and tolerances. The only bad effect from idling for a long time is that it wastes fuel and contaminates oil. Also, if ideled for a long time, it takes longer to heat up the catalytic converter, which results in excessive emission of pollutants. the mechanical stresses are governed by engine rpm, and little by load. so, in order to be good for both the car and environment, he suggests that the car be driven away immediately but slowly until the normal operating temperature is reached. I guess I'd better give the expert more credit than someone else. Acura NSX...simply the BEST... |
