Cold inflation pressure is a gauge pressure and not an absolute pressure. This article focuses on cold inflation pressures for passenger vehicles and trucks. The general principles are, of course, applicable to bicycle tires, tractor tires, and any other kind of tire with an internal structure that gives it a defined size and shape (as opposed ...
Carburetor heat (usually abbreviated to 'carb heat') is a system used in automobile and piston-powered light aircraft engines to prevent or clear carburetor icing. It consists of a moveable flap which draws hot air into the engine intake. The air is drawn from the heat stove, a metal plate around the (very hot) exhaust manifold.
Later systems used electric chokes or exhaust-heat chokes for cold enrichment, although these had issues of their own. Additionally, the vapor pressure of modern pump gasoline may not be appropriate to prevent percolation in the Ramjet fuel distribution spider. [5] The cranking signal valve was also the source of reliability issues.
In supercharged engines which use a carburetor, a partially-open throttle reduces the air pressure within the carburetor. In cold conditions, this low pressure air can cause ice to form at the throttle plate. Significant quantities of ice can cause engine failure, even with the engine operating at full rated power.
Goodyear Auto Service also provides free air pressure checks at any of their five locations in the Phoenix metro area and one in Tucson. They are open from Monday to Saturday from 8 a.m. to 7 p.m.
The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark.
