Gm Holden X22se 2.2l L4, Family Ii Engine

The GM Ecotec engine, besides known past its codename L850, is a family of all-aluminium inline-iv engines, displacing between i.iv and ii.v litres. While these engines were based on the GM Family Two 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 Leap Hill Manufacturing, in Jump Hill, Tennessee while the engine block and cylinder heads are bandage at Saginaw Metal Casting Operations in Saginaw, Michigan.

The 'Ecotec' name was adopted in 1994 for the new generation of Family Two engines (2000 in North America) . The name was already used for the Opel GM Family Two engine, Family 1 and Family 0 ranges. GM intended this new Ecotec to go its global four-cylinder, and it has already fully replaced their OHV I4 line.

The Ecotec engine is a DOHC 4-valve design with a lost foam cast aluminum block and head (L850 for 86 mm bore applications, and L880 for 88 mm bore^{[ commendation needed ]}), designed for displacements from one.eight to 2.four Fifty. Development began in 1994, past an international squad of engineers and technicians from Opel'south International Technical Development Centre in Rüsselsheim, Federal republic of germany, GM Powertrain in Pontiac, Michigan, and Saab in Södertälje, Sweden.^[2] Much of the development work on this project was carried out by Lotus Engineering, Hethel, United Kingdom. The engine uses aluminium pistons and bandage iron cylinder liners. Vibration is reduced with twin balance shafts.

The kickoff engine in the Ecotec Gen I line-up was Ecotec two.two L61, introduced in May 1999.

The current Ecotec line is manufactured in Tonawanda, New York,.^[2]

LK9 [edit]

This engine is also known equally B207 when used by Saab and Z20NET by Opel for apply in the Vectra C and Signum.

LK9 is a turbocharged two.0 L (one,998 cc) version of the L850 (86 mm bore) series Ecotec utilizing an all-new reinforced sand bandage aluminum cylinder head and upgraded internal components. The engine features a five-begetting forged steel crankshaft, strengthened connecting rods, redesigned pistons, piston oil cooling jets, reprofiled camshafts and an integrated oil cooler.^[iii] The exhaust valves are liquid sodium-cooled. All vehicles using this engine feature Saab's Trionic 8 (T8) engine management system too as a revised valve train. The timing chain and timing gears are besides new, along with Saab'south Direct Ignition system. The reinforcements, turbocharging, intercooling, internals, dual overhead camshaft, and such were developed past GM Powertrain Sweden (Saab Machine Powertrain). Information technology features an 86 mm (3.4 in) diameter and stroke and a nine.5:1 compression ratio. Maximum power is 210 hp (160 kW) at 5300 rpm and 221 ft⋅lb (300 N⋅thousand) of torque at 2500 rpm. Maximum boost is 12.iii psi (0.85 bar).

LSJ [edit]

The LSJ is a supercharged version of the LK9 Ecotec 2.0 Fifty (1,998 cc) with an 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.^[4] Information technology is rated at 205 hp (153 kW) at 5600 rpm and 200 ft⋅lb (271 N⋅k) at 4400 rpm with a compression ratio of 9.v:1 and a 6450 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 bargain with GM for the Supercharged ii.0 Fifty Ecotec for their Ariel Atom. The engine came in diverse ratings from 205 hp (153 kW) to 300 hp (224 kW).

The LSJ was on the Ward's x All-time Engines list for 2006.

L61 [edit]

2003 Pontiac Sunfire Ecotec engine

This engine is likewise known every bit a Z22SE in other countries such as the United Kingdom, Commonwealth of australia, and Europe.

The basic Family Two compages was essentially re-engineered in 2000 to become the Ecotec Gen I. Unlike its notably harsh predecessor, the engine was designed for smoothness. Dual in-cake 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 bandage into the block, and the A/C compressor and alternator were mounted directly on the block without brackets. The oil filter housing was bandage into the cake with a removable cover and replaceable paper element. Information technology did not employ an EGR valve. The Ecotec line is manufactured in Tonawanda, New York and Kaiserslautern, Germany, and was also manufactured for Saturn in Spring Loma, 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 Fifty-Series.^[2]

The L61 is a 2.2 L (2,198 cc) version with a lost-foam cast aluminum cylinder caput and block; it features an 86 mm (iii.4 in) bore and 94.6 mm (three.72 in) stroke ^[2] and either a nine.five: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).^[2]

The Ecotec ii.two, model L61 showtime appeared in the 2000 Saturn LS1; the L61-powered Saturn Ion also replaced the Saturn-powered Saturn S-Serial.

In that location 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 render-less fuel injection. The 2002 Saturn VUE was the outset North American variant of the L61 to be equipped with electronic throttle command, whereas other applications did non arise until 2005 in the Saturn ION and Chevrolet Cobalt. For 2007, introduced an updated version of the L61 based on the Gen Ii blueprint.

The supercharger and inlet manifold from the ii.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.ii supercharged version of this engine.

The L61 was used in the post-obit cars:

ii.0 LNF (Z20NHH Opel) [edit]

A turbocharged direct injected (redubbed Spark Ignition Direct Injection) Ecotec was introduced in the 2007 Pontiac Solstice GXP and Saturn Sky Crimson Line. In these applications, the engine is mounted longitudinally. Displacement is 2.0 L (1,998 cc) with a foursquare 86 mm (3.4 in) diameter and stroke. Compression is 9.2:1 and maximum boost is xx psi (1.4 bar), delivering 260 hp (190 kW) at 5300 rpm and 260 ft⋅lb (350 N⋅yard) of torque from 2500 to 5250 rpm. Engine redline is at 6300 rpm and premium fuel is recommended. The sodium filled frazzle valves were based on applied science developed for the Corvette V8 powertrains. The sodium fuses and becomes a liquid at idle, which improves conductivity and draws rut 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 450 psi (31 bar) at idle, and up to 2,250 psi (155 bar) at wide-open throttle. The "Gen Ii" cake is similar to the 2.4 Fifty and likewise features VVT technology. The Gen Two block was adult using data from racing programs and computer simulations. The bore walls and bulkheads were strengthened with a weight increment of 2.5 lb (ane.1 kg). The coolant jackets were expanded to improve heat transfer, resulting in a coolant chapters increment of 0.v liters.

In December 2008, GM released a Turbo Upgrade Kit for the LNF engine which increases horsepower to 290 hp (220 kW) and torque to upward to 340 ft⋅lb (460 N⋅m), depending on the model. The kit retails for $650 and includes remapped engine calibration and upgraded MAP sensors. The kit is covered by the cars' existing GM warranties.^[6]

L61 [edit]

In 2007, the L61 received a multitude of changes, that originated from the LE5. It switched to the higher-force Gen 2 block and received a revised cylinder head (enlarged frazzle ports) and camshaft design (increased exhaust valve duration). The engine also switched from wasted spark ignition to private scroll-on-plug ignition; this forced the cam encompass 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 let the engine to see PZEV standards.^[10] Pinch ratio is 10.0:1.

The L61 was used in the following cars:

2.5 [edit]

LCV [edit]

First appearing in the 2013 Chevrolet Malibu and 2013 Cadillac ATS, the 2.5 L Gen III cake has been reworked to reduce engine noise and vibrations, while improving fuel economy and low-stop torque.^{[xvi] [18] [xix]} LCV is scheduled to supersede the direct-injected 2.four Fifty throughout North American GM products within a year.^[20] Engine production started in April 2012 at GM's Tonawanda Engine found.

The new combustion organization developed with GM's proprietary computational fluid dynamics (CFD) analysis software features a college compression ratio which helps amend fuel efficiency and has improved knock resistance. The engine features dual overhead camshafts with continuously variable valve timing and increased-say-so cam phasing (increased phase rotation angle), a high-pressure returnless direct-injection fuel system with camshaft-driven fuel pump delivering 750 psi (52 bar) at idle and 2,250 psi (155 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 rpm.

The balance shafts are relocated from the cylinder block to oil pan module. The two-slice steel-aluminum oil pan features in-pan integrated oil-pump assembly driven by the balance shaft with a shorter inverted-molar chain. Other improvements include inverted-tooth concatenation driving the camshaft, forged steel crankshaft, cast aluminum bedplate with main begetting cap inserts made of iron, high-pressure fuel rail with rubber-isolated assembly, acoustically shielded plastic cover for the intake manifold, and structurally enhanced aluminum camshaft comprehend and front cover. These improvements helped reduce noise intensity by twoscore% compared to the 2.four 50 engine and change the dissonance signature into a college frequency higher up 2,000 Hz. The engine besides uses a variable-displacement oil pump and an actively controlled thermostat. Direct injection reduces emissions by 25%, while continuous cam phasing eliminates the need for an EGR system. Maximum engine speed is listed at 7000 rpm.

Displacement for the two.5 Fifty engine is 2,457 cc with an 88.0 mm (3.46 in) bore and 100.8 mm (three.97 in) stroke. Compression ratio is xi.three:1.

Same equally the LCV but features Intake Valve Lift Command (IVLC) arrangement provides two-stage variable valve lift in improver to continuous variable timing. Continuously commanded past engine control unit, the valve rocker arm switches betwixt high-elevator and depression-lift profiles on the camshaft, actuated by an oil command valve through a two-feed stationary hydraulic lash adjuster, allowing for either 4.0 or 10.5 mm lift.^[26] Information technology also features a beginning-cease system. Maximum engine speed is listed at 7000 rpm.
