How To Change Fuses Chevy Traverse 2011

The GM Ecotec engine, as well known past its codename L850, is a family of all-aluminium inline-four engines, displacing between 1.four and ii.five litres. While these engines were based on the GM Family II engine, the architecture was substantially re-engineered for the new Ecotec awarding 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 Colina Manufacturing, in Spring 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 Ii engines (2000 in Due north America) . The name was already used for the Opel GM Family 2 engine, Family 1 and Family 0 ranges. GM intended this new Ecotec to get 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 bandage aluminum block and caput (L850 for 86 mm bore applications, and L880 for 88 mm bore^{[ citation needed ]}), designed for displacements from ane.viii to two.4 Fifty. Development began in 1994, past an international team of engineers and technicians from Opel'south International Technical Evolution Center in Rüsselsheim, Federal republic of germany, GM Powertrain in Pontiac, Michigan, and Saab in Södertälje, Sweden.^[2] Much of the development piece of work on this project was carried out by Lotus Engineering, Hethel, U.k.. The engine uses aluminium pistons and cast atomic number 26 cylinder liners. Vibration is reduced with twin remainder shafts.

The get-go engine in the Ecotec Gen I line-upwardly was Ecotec 2.ii L61, introduced in May 1999.

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

LSJ [edit]

The LSJ is a supercharged version of the LK9 Ecotec 2.0 Fifty (1,998 cc) with an Eaton M62 Roots-blazon 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] It is rated at 205 hp (153 kW) at 5600 rpm and 200 ft⋅lb (271 N⋅m) at 4400 rpm with a compression ratio of 9.5:1 and a 6450 rpm redline. With the end of the Chevy Cobalt Southward/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 Fifty Ecotec for their Ariel Atom. The engine came in various ratings from 205 hp (153 kW) to 300 hp (224 kW).

The LSJ was on the Ward'southward 10 All-time Engines listing for 2006.

L61 [edit]

2003 Pontiac Sunfire Ecotec engine

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

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 residual shafts were integral to the design, the power-steering pump was mounted directly to the cylinder caput and driven by the intake camshaft, the water-pump housing was bandage into the block, and the A/C compressor and alternator were mounted direct on the cake without brackets. The oil filter housing was cast into the cake with a removable cover and replaceable paper element. Information technology did non use an EGR valve. The Ecotec line is manufactured in Tonawanda, New York and Kaiserslautern, Germany, and was also manufactured for Saturn in Leap Hill, Tennessee until Saturn'south 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.^[2]

The L61 is a 2.2 L (2,198 cc) version with a lost-cream bandage aluminum cylinder head and cake; it features an 86 mm (3.4 in) diameter and 94.vi mm (3.72 in) stroke ^[2] and either a 9.5:one compression ratio or a x.0:ane. The engine is 665 mm (26.2 in) in length, 642 mm (25.3 in) in width, 655 mm (25.8 in) in acme and approximately 139 kg (306 lb).^[2]

The Ecotec 2.ii, model L61 showtime appeared in the 2000 Saturn LS1; the L61-powered Saturn Ion too 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 college (ten:1) compression and more aggressive camshaft. The 2004–2008 Chevrolet Malibu uses a version with electronic throttle control and a special unitized frazzle manifold and catalytic converter. The Malibu and Saturn versions besides utilize return-less fuel injection. The 2002 Saturn VUE was the first Due 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 forth with modified software in the ECM, can create a 2.two supercharged version of this engine.

The L61 was used in the following cars:

2.0 LNF (Z20NHH Opel) [edit]

A turbocharged direct injected (redubbed Spark Ignition Straight Injection) Ecotec was introduced in the 2007 Pontiac Solstice GXP and Saturn Heaven Red Line. In these applications, the engine is mounted longitudinally. Displacement is two.0 Fifty (ane,998 cc) with a square 86 mm (3.4 in) bore and stroke. Compression is 9.two:i and maximum boost is 20 psi (1.four bar), delivering 260 hp (190 kW) at 5300 rpm and 260 ft⋅lb (350 Northward⋅g) of torque from 2500 to 5250 rpm. Engine redline is at 6300 rpm and premium fuel is recommended. The sodium filled exhaust valves were based on engineering developed for the Corvette V8 powertrains. The sodium fuses and becomes a liquid at idle, which improves electrical conductivity and draws estrus 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 directly injection systems pressurizes the fuel to 450 psi (31 bar) at idle, and upwardly to two,250 psi (155 bar) at wide-open throttle. The "Gen Ii" block is like to the ii.4 L and also features VVT engineering science. The Gen II block was developed using data from racing programs and computer simulations. The bore walls and bulkheads were strengthened with a weight increment of ii.5 lb (1.1 kg). The coolant jackets were expanded to improve heat transfer, resulting in a coolant chapters increase of 0.5 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 up to 340 ft⋅lb (460 N⋅m), depending on the model. The kit retailed for $650 and includes remapped engine calibration and upgraded three MAP sensors. The kit is covered by the cars' existing GM warranties.^[6] Heave force per unit area was increased from 18psi (ane.24 bar) to 21psi (one.44 bar).

L61 [edit]

In 2007, the L61 received a multitude of changes, that originated from the LE5. It switched to the higher-force Gen II block and received a revised cylinder caput (enlarged exhaust ports) and camshaft design (increased exhaust valve duration). The engine also switched from wasted spark ignition to individual coil-on-plug ignition; this forced the cam cover to exist redesigned. It was also switched to an E37 engine controller with new creepo and cam sensors (replacing timing sensor previously found in ignition cassette). These changes increment horsepower slightly and allow the engine to meet PZEV standards.^[10] Compression ratio is x.0:1.

The L61 was used in the post-obit cars:

2.v [edit]

LCV [edit]

Commencement 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 depression-end torque.^{[sixteen] [eighteen] [nineteen]} LCV is scheduled to supervene upon the directly-injected 2.4 L throughout North American GM products inside a year.^[20] Engine product started in April 2012 at GM'due south Tonawanda Engine plant.

The new combustion organization developed with GM'southward proprietary computational fluid dynamics (CFD) analysis software features a college pinch ratio which helps improve fuel efficiency and has improved knock resistance. The engine features dual overhead camshafts with continuously variable valve timing and increased-potency cam phasing (increased phase rotation angle), a high-pressure returnless direct-injection fuel organization 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 caput, 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-piece steel-aluminum oil pan features in-pan integrated oil-pump assembly driven past the balance shaft with a shorter inverted-tooth chain. Other improvements include inverted-molar chain driving the camshaft, forged steel crankshaft, bandage aluminum bedplate with main bearing cap inserts made of atomic number 26, high-pressure fuel track with rubber-isolated associates, acoustically shielded plastic comprehend for the intake manifold, and structurally enhanced aluminum camshaft cover and front comprehend. These improvements helped reduce noise intensity by 40% compared to the ii.4 Fifty engine and change the noise signature into a higher frequency above 2,000 Hz. The engine also uses a variable-displacement oil pump and an actively controlled thermostat. Directly 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 2.5 L engine is 2,457 cc with an 88.0 mm (3.46 in) diameter and 100.eight mm (iii.97 in) stroke. Compression ratio is 11.three:i.

LKW [edit]

Same as the LCV but features Intake Valve Lift Control (IVLC) system provides ii-stage variable valve lift in addition to continuous variable timing. Continuously commanded by engine control unit of measurement, the valve rocker arm switches betwixt high-lift and low-lift profiles on the camshaft, actuated by an oil control valve through a ii-feed stationary hydraulic lash adjuster, allowing for either 4.0 or ten.5 mm elevator.^[26] It also features a beginning-stop arrangement. Maximum engine speed is listed at 7000 rpm.

HCCI [edit]

At Tech Show Torino 2008, GM Powertrain Europe announced the ignition-less HCCI (Homogeneous Charge Compression Ignition) mode of the directly injection version of ii.2 L engine.^[27] HCCI version is equipped with two-step adjustable valve lift with variable cam phasing and advanced ECU with cylinder force per unit area sensors, uses lean burn cycle similar to that of a diesel fuel engine, and is claimed to further reduce fuel consumption by xv%.^[28]
