-
Z'ed
- When a frame is cut,
usually in front of the rear wheels, and a section is welded in to raise the
axle so large tires can be used at stock body heights, racers say their car
has been z'ed [pronounced ZEED, not ZED], referring to the new
appearance of the frame.
-
Zener diode
- A
semiconductor used on British Motorcycles
for many years as a Voltage regulator. When the Voltage
across the Zener Diode
reached a certain point, the element
would begin to conduct Current,
routing it to ground, thus preventing the Battery
from overcharging.
- Zephrr
- Pearl Izumi's highly wind resistant, water repellent, lightweight fabric that keeps the
cold wind out and maintains breathability.
-
Zerk fitting
- A
small valve that allows grease to be added to a Ball joint
with a Grease gun
and prevents the grease
from leaking out when pressure is placed on the area. Incorrectly
pronounced zert. Also called Grease fitting
- Zero
-
An amount or reading (often set arbitrarily) where there is an absence of value or which is the beginning of something.
- Zero absolute
pressure
- A total vacuum. Zero on the absolute pressure scale
-
Zero-emission vehicle
- (ZEV)
- A vehicle which itself produces no emissions, such as electric powered
vehicles. The concept does not take into account the fact that electric cars
use the electric power of batteries that are normally charged by power
supplied by electric power plants (which generally do produce certain
emissions); Californian laws require that from 1998, 2% of new cars must be
ZEVs.
- A vehicle meeting either
EPA's CFV ZEV
standards or CARB's California Low-Emission Vehicle Program ZEV standards.
ZEV standards, usually met with electric vehicles, require zero vehicle (not
power plant source) emissions. ZEVs earn more Clean-Fuel Fleet Vehicle
Program credits than
ULEVs. ZEVs may also
meet ILEV
standards.
- A vehicle that is certified to meet the most stringent emission standards
established by the California Air Resources Board (CARB). These standards
require zero regulated emissions of nonmethane organic gases (NMOGs), carbon
monoxide (CO) and nitrogen oxides (NOx). A ZEV is most likely powered by
electricity, fuel cells, or hydrogen.
-
Zero governor
- A regulating device that is normally adjusted to deliver gas at atmospheric pressure within its flow rating.
- Zero ice
- Trade name for dry ice.
-
Zero offset
-
-
Zero-offset steering
- A Steering
system
whose geometry has a Scrub radius
of zero. This
configuration minimizes the steering effects produced during acceleration
(with front drive) or braking on varying Traction
surfaces.
-
Zero-velocity spreader
- A spreader that uses air flow to dispense chemicals (liquid and/or dry deicers) in a continuous
controlled pattern with material blown onto the road in one direction at approximately the same speed
the truck moves in the other direction. The deicing materials strike the pavement at zero velocity and
stay where they fall.
