In 2012, Cadillac produced the first American car using R-1234yf. [20] Since then, Chrysler, [21] GMC, [22] and Ford [23] have all begun transitioning vehicles to R1234yf. [16] Japanese automakers are also transitioning to R1234yf. Honda and Subaru began to introduce the new refrigerant with the 2017 models. [20]
The Northstar engine is a family of high-performance 90° V engines produced by General Motors between 1993 and 2011. Regarded as GM's most technically complex engine, the original double overhead cam, four valve per cylinder, aluminum block/aluminum head V8 design was developed by Oldsmobile R&D, [citation needed] but is most associated with Cadillac's Northstar series.
Polyolester oil (POE oil) is a type of wax-free synthetic oils used in refrigeration compressors that is compatible with the refrigerants R-134a, R-410A, and R-12. [1] POE oils are used as a lubricant in systems using the refrigerant HFC-134a when replacing CFC-12 , as these systems traditionally use mineral oil , [ 2 ] which HFC-134a does not ...
It has varying oil content from nil oil (synthetic coolant). This coolant can either keep its phase and stay liquid or gaseous, or can undergo a phase transition, with the latent heat adding to the cooling efficiency. The latter, when used to achieve below-ambient temperature, is more commonly known as refrigerant.
The second automotive air conditioning refrigerant invented was R-134a. R-134a is a hydrofluorocarbon refrigerant that contains fluorine and hydrogen. The successor to R-12, R-134a was a new refrigerant that no longer contained chlorine that could deplete the ozone layer. R-134a is a greenhouse gas, it has a lower global warming potential than ...
According to ASHRAE standard 34, the R-number of a chemical refrigerant is assigned systematically according to its molecular structure and has between two and four digits. If there are carbon -carbon multiple bonds , there are four digits in all: the number of these bonds is the first digit and the number of carbon atoms minus one (C-1) is next.
Cadillac's new 368 cu in (6.0 L) L62 V8 with Digital Fuel Injection was a no-cost option except in California, where the fuel-injected Oldsmobile 350 was retained for emissions purposes. [15] 1985 Seville rear, two-tone with aftermarket fake spare wheel feature 1984 Cadillac Seville (front)
HC-12a, also called ES-12a, OZ-12a, DURACOOL 12a [1] and Hydrocarbon Blend B, is marketed as a "drop-in" replacement refrigerant for R-12 and other refrigerants. HC-12a is a mixture of hydrocarbons, specifically propane (R-290) and isobutane (R-600a), and is therefore considered nearly non-ozone-depleting.
