Editing General Motors 122 engine (section)

==Generation II==

===2.0===

====LL8====
This engine replaced the '''LQ5''' and was used from 1987 until 1989. It featured throttle-body fuel injection and produced {{cvt|90|hp|kW|0}} and {{cvt|108|lbft|Nm|0}} of torque.

Applications:
*1987–1989 [[Buick Skyhawk]]
*1987–1989 [[Chevrolet Beretta]]
*1987–1989 [[Chevrolet Cavalier]]
*1987–1989 [[Chevrolet Corsica]]
*1987–1988 [[Oldsmobile Firenza]]
*1987–1989 [[Pontiac Tempest]]

====LM3====
For the 1990 model year, GM replaced the 2.0-liter engine with a stroked version displacing 2.2 liters and using [[throttle-body fuel injection]] (TBI). Commonly called the '''2.2''', it produced {{cvt|95|hp|0}} and {{cvt|120|lbft|Nm|0}} of torque.

Applications:
*1990–1991 [[Chevrolet Beretta]]
*1990–1991 [[Chevrolet Cavalier]]
*1990–1991 [[Chevrolet Corsica]]
*1990–1991 [[Pontiac Tempest]]

====LN2====
For 1992, the '''2.2''' received [[multi-port fuel injection]] (MPFI), replacing the [[Throttle-body injection|TBI]] version in the J-body cars and increasing power to {{cvt|110|hp|0}} and {{cvt|130|lbft|Nm|0}} of torque. In the L-body cars, it was converted straight to Sequential Fuel Injection. In 1994, all 2.2-liter engines were updated to [[sequential multi-port fuel injection]] and power increased to {{cvt|120|hp|0}}, with torque increasing to {{cvt|140|lbft|Nm|0}}. The MPFI and SFI versions produced enough power to allow the '''2.2''' to replace the old [[Pontiac (automobile)|Pontiac]] [[GM Iron Duke engine|Iron Duke]] engine as the 4-cylinder offering in the S/T trucks and A-body cars. For 1996, it became known as the '''Vortec 2200''' in the S/T trucks.

For 1998, the engine was revised for emissions regulations and became known as the '''2200'''. This revision lowered power to {{cvt|115|hp|kW|0}} at 5000&nbsp;rpm, and torque to {{cvt|135|lbft|Nm|0}} at 3600&nbsp;rpm. The engine was discontinued in 2003, replaced by the 2.2-liter DOHC [[L850 engine|Ecotec]] engine. Although it displaces 134 cu. in, the 2.2-liter OHV is still commonly referred to as the GM 122 today, and has been reputed for its simplicity, reliability, and ease of maintenance in the J-body cars and S-series trucks, and a few L-body cars. The 2003 model '''LN2''' is equipped with [[secondary air injection]].<ref>{{cite web|url=http://archives.media.gm.com/division/2003_prodinfo/03_powertrain/03_truck_engine/index.html|title=2003 Truck Engines|publisher=[[General Motors]]|accessdate=16 April 2014}}</ref>

*1995–2002 [[Pontiac Sunfire]]

====L43====
The '''Vortec 2200''' (RPO code '''L43''') is an OHV [[straight-4]] [[truck]] engine. This engine is equipped with [[secondary air injection]], and is [[flex-fuel]] capable. It is entirely different from the [[GM Iron Duke engine|Iron Duke]], and was the last North American iteration of the [[GM 122 engine]]. The 2200 uses an iron block and aluminum two-valve cylinder head. Output is {{cvt|120|hp|kW|0}} at 5000 [[revolutions per minute|rpm]] and {{cvt|140|lbft|Nm|0}} at 3600&nbsp;rpm. Displacement is {{cvt|2189|cc|L cuin|1|order=flip}} with an {{cvt|89x88|mm|in|2}} bore and stroke. 2200s were built at [[Tonawanda Engine|GM's Tonawanda engine plant]] in [[Buffalo, New York|Buffalo]]. This engine was replaced by the '''LN2''' in September 2002.<ref>{{cite web|url=http://archives.media.gm.com/division/powertrain/products/engine/truckengines/2003/truck_benefits/ln2.doc|title=Vortec 2200 2.2L L4 (LN2) Truck Engine, 2003 model year|format=doc|publisher=General Motors|accessdate=16 April 2014}}</ref> This engine did not commonly come with an EGR valve from 1998-2002 on the S-series trucks despite earlier versions using one. Instead a block off plate is on the back of the cylinder head. The camshaft on the 1998 model year uses a higher lift design. (0.288 inches intake and exhaust.) Meanwhile the 1999 and newer trucks use a lower lift camshaft. (0.263 inches intake and exhaust.) This was pulled from the Haynes automotive manual for the S series trucks. 

Applications:
*1998–2002 [[Chevrolet S-10|Chevrolet S-10, GMC Sonoma, and Isuzu Hombre]]
