ILC

Acronym for Idle Load Compensator

ILEV

Acronym for inherently low-emission vehicle

Illuminated

Lit up

Illuminated entry system

An additional courtesy lighting system which illuminates the door entry area when the door is ajar; consists usually of lights in the lower door panels and footwells

Illumination control

A switch which dims the interior dash lights

Illuminite

Unlike reflective strips illuminite technology makes the entire garment reflective. The illumiNITE process embeds millions of microscopic satellite dishes into the weave of the fabric. These dishes act like mirrors to reflect back to the original light source. Because the dishes are embedded into the fabric, the garment remains machine washable without losing any of its reflective properties.

ILSAC

Acronym for US based International Lubricants Standardization and Approval Committee is controlled by the API. It includes the major the US vehicle manufacturers, the US engine manufacturers association and Japanese manufacturers who assemble vehicles in the US. The standards work in addition to the API SH, SJ, and SM standards for engine oils and are effectively the fuel economy version of the those oil specifications. The ILSAC GF-1 standard indicates the oil meets both API SH and the Energy Conserving II (EC-II) requirements. It was created in 1990 and upgraded in 1992 and became the minimum requirement for oil used in American and Japanese automobiles. An EC-II oil provides a 2.7% fuel economy improvement over reference used in a laboratory test engine. ILSAC GF-1 specifications apply to multigrade oils that have a 0, 5 and 10 W rating and 20, 30, 40 or 50 summer rating. ILSAC GF-2 replaced GF-1 in 1996. The oil must meet both API SJ and EC-II requirements. The GF-2 standards requires 0W-30, 0W-40, 5W-20, 5W-30, 5W-40, 5W-50, 10W-30, 10W-40 and 10W-50 motor oils to meet stringent requirements for phosphorus content, low temperature operation, high temperature deposits and foam control. GF-3 an oil must meet both API SL and the EC-II requirements. The GF-3 standard has more stringent parameters regarding long-term effects of the oil on the vehicle emission system, improved fuel economy and improved volatility, deposit control and viscosity performance. The standard also requires less additive degradation and reduced oil consumption rates over the service life of the oil. The GF-4 standard was introduced in 2004 and increases the compliance parameters over GF-3 by a significant margin.
