context_page_description: The GM Ecotec engine, also known by its codename L850, is a family of all-aluminium inline-four engines, displacing between 1.4 and 2.5 litres. While these engines were based on the GM Family II engine, the architecture was substantially re-engineered for the new Ecotec application produced since 2000. This engine family replaced the GM Family II engine, the 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.
context_section_description: 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, New York and Kaiserslautern, Germany, and was also manufactured for Saturn in Spring Hill, Tennessee until Saturn's discontinuation. In North America this engine replaced both the Quad-4 and the GM 122 engines and first appeared in the 2000 Saturn L-Series.
  The L61 is a 2.2 L (2,198 cc) version with a lost-foam cast aluminum cylinder head and block; it features an 86 mm (3.4 in) bore and 94.6 mm (3.72 in) stroke  and either a 9.5:1 compression ratio or a 10.0:1. The engine is 665 mm (26.2 in) in length, 642 mm (25.3 in) in width, 655 mm (25.8 in) in height and approximately 139 kg (306 lb).
  The Ecotec 2.2, model L61 first appeared in the 2000 Saturn LS1; the L61-powered Saturn Ion also replaced the 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 2004–2008 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 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:
  This engine also powered the Japanese-market Subaru Traviq, a badge-engineered Opel Zafira A.
  Following the GM-Fiat agreement, the 2.2 L engine is also used in
  Fiat Croma unmodified
  Alfa Romeo 159 heavy modified with Gasoline direct injection
