Static System Pressure

The pressure of a vapor or liquid in a system under ambient temperature conditions with no load imposed.

Static Tension

The tension in the belt when the drive is at rest, a factor that determines drive efficiency, service life, or other operating characteristics.

Static Timing

To set the ignition timing on an engine that is not running.

Static Voltage

Voltage at rest or stored, not moving in the circuit.

Statically Balanced

A tire or other rotating device that is balanced at rest so that it will not turn when free to do so because its weight mass is distributed evenly around the circumference of the tire or the axis of rotation.

Station Wagon

An enclosed two- to nine-passenger vehicle which is characterized by it's roof, extending for the length of the vehicle, allowing a spacious interior cargo area in the rear and having a rear door or hatch to provide access.

Stationary Fifth Wheel

A non-movable fifth wheel whose location on the tractor frame is fixed.

Statistic Filtering

The control module internally charts the results of diagnostic testing over a period of time and creates a baseline for testing.

Statistical Filtering

The PCM internally charts the results of diagnostic testing over a period of time and creates a baseline for testing. By doing this, the PCM is able to filter out information that could cause a false DTC to set.

Stator

1. A reaction device or member unit inside the torque converter, mounted on a one-way roller or sprag clutch, having vanes to redirect the fluid flow that discharges from the turbine center back toward the impeller at an angle most advantageous to torque multiplication. 2. A stationary field having three windings to provide overlapping, three-phase electrical pulses to smooth the current flow.

Stator Assembly

The reaction member or torque multiplier that is supported in a free-wheel roller race splined to the valve and front support assembly.

Stator Gain

The increase in voltage, amperage, or wattage in the alternators stator.

Stator Support

A part of the transmission pump housing in which the stator assembly in a torque converter locks.

Steady Rest

A journal support on a camshaft or crankshaft grinder to prevent vibration.

Steam Engine

An external-combustion engine operated by steam generated from a boiler.

Steam Holes

Passages designed to permit the flow of steam in an engine cooling system in hot spot areas where steam is expected to collect.

Steam Rollers

Huge drag-racing slicks.

Steel

Refined iron metal with most of the carbon removed.

Steel Ship Gasket

The same as corrugated metal gasket.

Steelies

Wheels made of ferrous material.
