{{Redirect|LNF}}
The '''GM Ecotec engine''', also known by its codename '''L850''', is a family of [[inline-four engine]]s, displacing between 1.2 and 2.5 litres. Confusingly, the ''Ecotec'' name was also applied to both the [[Buick V6 engine|Buick V6 Engine]] when used in [[Holden]] Vehicles, as well as the final DOHC derivatives of the previous [[GM Family II engine]]; the architecture was substantially re-engineered for this new Ecotec application produced since 2000. This engine family replaced the GM Family II engine, the [[General Motors 122 engine|GM 122 engine]], the [[Saab H engine]], and the [[Quad 4 engine]]. It is manufactured in multiple locations, to include [[Spring Hill Manufacturing]], in [[Spring Hill, Tennessee]], with engine blocks and cylinder heads cast at [[Saginaw Metal Casting Operations]] in [[Saginaw, Michigan]].

The "[[Ecotec]]" name was adopted in 1994 for the new generation of Family II engines (2000 in North America) . The name was already used for the Opel GM Family II engine, [[GM Family 1 engine|Family 1]] and [[GM Family 0 engine|Family 0]] ranges. GM intended this new Ecotec to become its global 4-cylinder, and it has already fully replaced their [[GM 122 engine|OHV I4]] line.

The Ecotec engine is a [[DOHC]] [[multivalve|4-valve]] design with a lost foam cast aluminium block and head (L850 for 86&nbsp;mm bore applications, and L880 for 88&nbsp;mm bore{{Citation needed|date=August 2014}}), designed for displacements from 1.8 to 2.4&nbsp;L. Development began in 1994, by an international team of engineers and technicians from [[Opel]]'s ''International Technical Development Center'' in [[Rüsselsheim]], Germany, [[GM Powertrain]] in [[Pontiac, Michigan]], and [[Saab Automobile|Saab]] in [[Södertälje]], Sweden.<ref name="Auto Channel 2.2">{{cite web|title=GM's Ecotec 2.2-Liter 4-Cylinder Engine Delivers|url=http://www.theautochannel.com/news/2002/02/07/035471.html|work=[[The Auto Channel]]|access-date=15 March 2013|location=Pontiac, Michigan}}</ref> Much of the development work on this project was carried out by [https://web.archive.org/web/20060227023927/http://www.grouplotus.com/eng/ Lotus Engineering], Hethel, United Kingdom. The engine uses [[aluminium]] pistons and cast [[iron]] cylinder liners. Vibration is reduced with twin [[balance shaft]]s.

The first engine in the Ecotec Gen I line-up was [[#L61|Ecotec 2.2 ''L61'']], introduced in May 1999.

The current Ecotec line is manufactured in [[Tonawanda (town), New York|Tonawanda, New York]].<ref name="Auto Channel 2.2" />

The '''LSJ''' is a supercharged version of the LK9 Ecotec {{cvt|1998|cc|L|1|order=flip}} with an [[Eaton Corporation|Eaton]] M62 [[Roots-type supercharger]] and air-to-liquid [[intercooler]]. The LSJ shares many of its components with the LK9 such as: piston cooling jets, oil cooler, pistons, connecting rods, crankshaft, oil pan, sodium-filled exhaust valves and cylinder head.<ref>{{cite web|url=http://archives.media.gm.com/division/2005_prodinfo/powertrain/index.html|access-date=16 April 2014 |title=Site Maintenance }}</ref> It is rated at {{cvt|205|hp|0}} at 5600&nbsp;rpm and {{cvt|200|lbft|Nm|0}} at 4400&nbsp;rpm with a compression ratio of 9.5:1 and a 6450&nbsp;rpm redline. With the end of the Chevy Cobalt S/C SS and Saturn Ion Red Line, the LSJ was discontinued after 2007. In late 2005 [[Brammo Motorsports]] struck a deal with GM for the [[Supercharged]] 2.0&nbsp;L Ecotec for their [[Ariel Atom]]. The engine came in various ratings from {{cvt|205|hp|0}} to {{cvt|300|hp|0}}.

The LSJ was on the [[Ward's 10 Best Engines]] list for 2006.

The basic Family II architecture was substantially re-engineered in 2000 to become the ''Ecotec'' Gen I. Unlike its notably harsh predecessor, the engine was designed for smoothness. Dual in-block balance shafts were integral to the design, the power-steering pump was mounted directly to the cylinder head and driven by the intake camshaft, the water-pump housing was cast into the block, and the A/C compressor and alternator were mounted directly on the block without brackets. The oil filter housing was cast into the block with a removable cover and replaceable paper element. It did not use an EGR valve. The Ecotec line is manufactured in [[Tonawanda (town), New York|Tonawanda, New York]], and [[Kaiserslautern, Germany]], and was also manufactured for [[Saturn Corporation|Saturn]] in [[Spring Hill, Tennessee]], until Saturn's discontinuation. In North America, this engine replaced both the [[GM Quad-4 engine|Quad-4]] and the [[GM 122 engine|GM 122]] engines and first appeared in the 2000 [[Saturn L-Series]].<ref name="Auto Channel 2.2" />

The '''L61''' is a {{cvt|2198|cc|L|1|order=flip}} version with a [[Lost-foam casting|lost-foam cast]] aluminium cylinder head and block; it features an {{cvt|86|mm|in}} bore and {{cvt|94.6|mm|in}} stroke<ref name="Auto Channel 2.2" /> and either a 9.5:1 compression ratio or a 10.0:1. The engine is {{cvt|665|mm|in}} in length, {{cvt|642|mm|in}} in width, {{cvt|655|mm|in}} in height and approximately {{cvt|139|kg|lb}}.<ref name="Auto Channel 2.2" />

The '''Ecotec 2.2''', model '''L61''' first appeared in the 2000 [[Saturn L-Series|Saturn LS1]]; the L61-powered [[Saturn Ion]] also replaced the [[Saturn I4 engine|Saturn]]-powered [[Saturn S-Series]].

There are a few variations to the standard L61. The 2003 [[Saturn L-Series]] has a high output version with higher (10:1) compression and more aggressive [[camshaft]]. The 2004&ndash;2008 [[Chevrolet Malibu#Seventh generation (2008)|Chevrolet Malibu]] uses a version with [[electronic throttle control]] and a special unitized [[exhaust manifold]] and [[catalytic converter]]. The Malibu and Saturn versions also use return-less [[fuel injection]]. The 2002 [[Saturn VUE]] was the first North American variant of the L61 to be equipped with [[electronic throttle control]], whereas other applications did not arise until 2005 in the [[Saturn ION]] and [[Chevrolet Cobalt]]. For 2007, introduced an [[#L61_2|updated version]] of the ''L61'' based on the Gen II design.

The supercharger and inlet manifold from the 2.0 Ecotec LSJ engine can be purchased as an official kit from GM and along with modified software in the ECM, can create a 2.2 supercharged version of this engine.

The L61 was used in the following cars:

[[File:Car show 013.jpg|right|thumb|250px|Ecotec LNF in a [[Pontiac Solstice]]]]
A turbocharged [[Gasoline direct injection|direct-injected]] (redubbed ''Spark Ignition Direct Injection'') Ecotec was introduced in the 2007 [[Pontiac Solstice|Pontiac Solstice GXP]] and [[Saturn Sky|Saturn Sky Red Line]]. In these applications, the engine is mounted longitudinally. Displacement is {{cvt|1998|cc|L|1|order=flip}} with a square {{cvt|86|mm|in}} bore and stroke. Compression is 9.2:1 and maximum boost is {{cvt|1.4|bar|psi|order=flip}}, delivering {{cvt|260|hp|kW}} at 5300&nbsp;rpm and {{cvt|260|lbft|N.m}} of torque from 2500 to 5250&nbsp;rpm. Engine redline is at 6300&nbsp;rpm and premium fuel is recommended. The sodium filled exhaust valves were based on technology developed for the Corvette V8 powertrains. The sodium fuses and becomes a liquid at idle, which improves thermal conductivity and draws heat away from the valve face and valve guide towards the stem to be cooled by the engine oil circulating in this area. The camshaft-driven direct injection systems pressurizes the fuel to {{cvt|31|bar|psi|order=flip}} at idle, and up to {{cvt|155|bar|psi|order=flip}} at wide-open throttle. The "Gen II" block is similar to the 2.4&nbsp;L and also features [[Variable valve timing|VVT]] technology. The Gen II block was developed using data from racing programs and computer simulations. The bore walls and bulkheads were strengthened with a weight increase of {{cvt|2.5|lb}}. The coolant jackets were expanded to improve heat transfer, resulting in a coolant capacity increase of 0.5&nbsp;liters.

In December 2008, GM released a Turbo Upgrade Kit for the LNF engine which increases horsepower to {{cvt|290|hp|kW}} and torque to up to {{cvt|340|lbft|N.m}}, depending on the model. The kit retailed for $650 and includes remapped engine calibration and upgraded 3 MAP sensors. The kit is covered by the cars' existing GM warranties.<ref>{{cite web|author= Chris Shunk |url=http://www.autoblog.com/2008/12/18/gm-releases-turbo-upgrade-kit-for-solstice-gxp-sky-redline-and/ |title=GM releases turbo upgrade kit for Solstice GXP, Sky Redline and HHR SS |publisher=Autoblog.com |access-date=2012-01-24}}</ref> Boost pressure was increased from 18psi (1.24 bar) to 21psi (1.44 bar).

===2.2===
====L61====
In 2007, the '''L61''' received a multitude of changes, that originated from the ''LE5''. It switched to the higher-strength Gen II block and received a revised cylinder head (enlarged exhaust ports) and camshaft design (increased exhaust valve duration). The engine also switched from [[wasted spark]] ignition to individual [[Direct ignition|coil-on-plug]] ignition; this forced the cam cover to be redesigned. It was also switched to an E37 engine controller with new crank and cam sensors (replacing timing sensor previously found in ignition cassette). These changes increase horsepower slightly and allow the engine to meet [[PZEV]] standards.<ref>{{cite web|title=2008 Ecotec 2.2L I4 ( L61 )|url=http://g5.wrath.org/08_L61.doc|access-date=30 July 2014}}</ref> Compression ratio is 10.0:1.

The L61 was used in the following cars:

====LAF====
[[File:Chevrolet ecotec 2.4.jpg|thumb|GM Ecotec 2.4]]
The '''LAF''' is a direct injected 2.4&nbsp;L. It uses technology based on GM's other four-cylinder direct-injection applications, but with unique features designed for its specific application. This includes an 11.2:1 compression ratio that helps build power, slightly dished pistons that increase combustion efficiency and injectors with an application-specific flow rate.<ref>{{cite web|url=http://www.gminsidenews.com/forums/f63/naias-09-2010-ecotec-2-4l-sidi-73038/ |title=NAIAS 09: 2010 ECOTEC 2.4l SIDI |date=22 January 2010 |publisher=Gminsidenews.com |access-date=2012-01-24}}</ref><ref name="GMpress20081217">{{cite news |last=Roth |first=Dan |date=2008-12-17 |title=DI FTW: GM unveils new direct-injection 2.4&nbsp;L EcoTec and 3.0&nbsp;L V6 |work=autoblog.com |url=http://www.autoblog.com/2008/12/18/di-ftw-gm-new-direct-inject-2-4l-ecotec-and-3-0l-v6 |access-date=2008-12-17}}</ref>

First appearing in the 2013 [[Chevrolet Malibu]] and 2013 [[Cadillac ATS]], the 2.5 L ''Gen III'' block has been reworked to reduce engine noise and vibrations, while improving fuel economy and low-end torque.<ref name="2.0T_genIII_PR">{{Cite web|url=http://media.gm.com/media/us/en/gm/news.detail.html/content/Pages/news/us/en/2012/Sep/0920_malibu_turbo_eng.html|title = New 2.0L Turbo Engine Gives the 2013 Chevrolet Malibu Enhanced Performance and Refinement|date = 20 September 2012}}</ref><ref>{{Cite web|url=http://media.gm.com/media/us/en/gm/news.detail.html/content/Pages/news/us/en/2011/Sep/0919_ecotec_25_efficient|title = New Ecotec 2.5L Engine More Efficient, Refined and Powerful|date = 19 September 2011}}</ref><ref>{{Cite web|url=http://media.gm.com/media/us/en/chevrolet/news.detail.html/content/Pages/news/us/en/2011/Sep/0919_malibu_noise_vibration|title=All-New Ecotec 2.5L Powers Chevrolet Malibu's Quest for Quietness|date=19 September 2011}}</ref> LCV is scheduled to replace the direct-injected 2.4 L throughout North American GM products within a year.<ref>{{cite web |url=http://blog.caranddriver.com/gm-to-replace-2-4-liter-fours-with-2-5-liters-across-the-range/ |title=Car and Driver Blog » GM to Replace 2.4-liter Fours with 2.5-liters Across the Range |website=blog.caranddriver.com |url-status=dead |archive-url=https://web.archive.org/web/20120113054212/http://blog.caranddriver.com/gm-to-replace-2-4-liter-fours-with-2-5-liters-across-the-range |archive-date=2012-01-13}} </ref> Engine production started in April 2012 at GM's [[Tonawanda Engine]] plant.

The new combustion system developed with GM's proprietary computational fluid dynamics (CFD) analysis software features a higher compression ratio which helps improve fuel efficiency and has improved knock resistance. The engine features dual overhead camshafts with continuously variable valve timing and increased-authority cam phasing (increased phase rotation angle), a high-pressure returnless direct-injection fuel system with camshaft-driven fuel pump delivering {{cvt|750|psi|bar}} at idle and {{cvt|2250|psi|bar}} at full load, higher-flowing intake and exhaust ports in the cylinder head, electronic throttle control and pistons with jet-spray oil cooling. The engine redline is 7000&nbsp;rpm.

The balance shafts are relocated from the cylinder block to oil pan module. The two-piece steel-aluminium oil pan features in-pan integrated oil-pump assembly driven by the balance shaft with a shorter inverted-tooth chain. Other improvements include inverted-tooth chain driving the camshaft, forged steel crankshaft, cast aluminium bedplate with main bearing cap inserts made of iron, high-pressure fuel rail with rubber-isolated assembly, acoustically shielded plastic cover for the intake manifold, and structurally enhanced aluminium camshaft cover and front cover. These improvements helped reduce noise intensity by 40% compared to the 2.4&nbsp;L engine and change the noise signature into a higher frequency above 2,000&nbsp;Hz. The engine also uses a variable-displacement oil pump and an actively controlled thermostat. [[Gasoline direct injection|Direct injection]] reduces emissions by 25%, while [[continuous cam phasing]] eliminates the need for an EGR system. Maximum engine speed is listed at 7000&nbsp;rpm.

Displacement for the 2.5&nbsp;L engine is 2,457&nbsp;cc with an {{cvt|88.0|mm|in}} bore and {{cvt|100.8|mm|in}} stroke. Compression ratio is 11.3:1.

Same as the LCV but features Intake Valve Lift Control (IVLC) system provides two-stage [[variable valve lift]] in addition to continuous variable timing. Continuously commanded by the [[engine control unit]], the valve rocker arm switches between high-lift and low-lift profiles on the camshaft, actuated by an oil control valve through a two-feed stationary [[hydraulic lash adjuster]], allowing for either 4.0 or 10.5&nbsp;mm lift.<ref>{{Cite web|url=http://media.gm.com/media/us/en/gm/news.detail.html/content/Pages/news/us/en/2012/Sep/0917_intakevalve.html|title = 2014 Impala Engine Gets a High-Tech Lift|date = 17 September 2012}}</ref> It also features a [[start-stop system]].
