DICTIONARY OF AUTOMOTIVE TERMS - "Vr"

VR
  1. Acronym for Variable reluctance sensor
  2. Acronym for Voltage Regulator
VRA
Acronym for Voluntary restraint agreement.
VRDV
Acronym for Vacuum retard delay valve
VR engine
A new engine design a combination of in-line and V-engine, the V-angle being reduced (VR) to about 15°. This results in a block which is shorter than a four-cylinder unit of similar capacity. Unlike conventional V-8 engines, the VR engine is topped by a single cylinder head
VREF
Acronym for Reference Voltage (from PCM) The power supplied by the computer control unit to some sensors regulated at a specific DC voltage
VRESER
Acronym for Vacuum reservoir
VREST
Acronym for Vacuum restrictor
VRIS
Acronym for Variable Resonance Induction System
V RMS
Voltage root mean square; average voltage equal to the maximum voltage multiplied by a constant.
VRS
  1. Acronym for Variable reluctance sensor
  2. Acronym for Vacuum Regulator/Solenoid (Ford)
VRV
