[[General Motors Corporation|General Motors]]' Generation II '''LT''' small block V8 engine debuted in 1992 on the 1992 [[Chevrolet Corvette]]. Few parts from the Generation II engine are interchangeable with the old [[Chevrolet Small-Block engine|generation I engine]]. The LT engine uses a new engine block, cylinder head, timing cover, water pump, intake manifold and accessory brackets. On the other hand, the engine mounts and [[bell housing]] bolt pattern remain the same, so the newer engine can readily be swapped into an older vehicle. One visible difference is the new "opti-spark" distributor which is located on the front of the engine behind the gear-driven water pump.
'''JTD''' (uniJet Turbo Diesel) is [[Fiat Group]]'s term for its current [[common rail]] [[turbodiesel]] engine range.  The '''MultiJet''' name is used in the second generation JTD common rail units. Most of the [[Fiat]], [[Alfa Romeo]] and [[Lancia]] range has JTD engines. Ownership of some Fiat JTD designs is shared with [[General Motors Corporation|General Motors]] as part of a settlement of the failed merger between the two auto conglomerates. [[GM Powertrain Europe]] group in [[Turin, Italy]] manages their interest in these engines. Some [[PSA Peugeot Citroën]] diesel engines are also rebadged as JTD. A new generation JTD engine, Multijet II is under development and will be available in 2009, the Fiat Powertrain Technologies sees its very important step in diesel technology. This new technology will be first available for the 1.3 litre JTD engine.<ref name="fiatgroup.com/en-us">{{Cite web|url=http://www.fiatgroup.com/en-us/innovation/crf_activities/prt/Pages/Multijet.aspx|title=Multijet II|accessdate=2009-01-26|work=fiatgroup.com/en-us}}</ref>


A key technical difference between the original Chevrolet small block V8 and the Generation II engine is the cooling system. The LT engine employs [[reverse cooling]], meaning that the coolant starts at the heads and then flows down through the block. This allows for a higher compression ratio and more spark advance since the heads are kept at a cooler temperature. A secondary benefit of reverse cooling is that cylinder temperatures are higher and more consistent.
==1.3==
A small 1.3&nbsp;L (1248&nbsp;cc) version (called the SDE, Small Diesel Engine) is produced in [[Bielsko-Biała]], [[Poland]]. The Multijet 75&nbsp;[[Horsepower#PS|PS]] version was chosen in 2005 as the [[International Engine of the Year]] in the 1-litre to 1.4-litre category.


{{SectOR|date=September 2008}}
There are four versions of this engine: a {{Auto PS|70}}, a {{Auto PS|75}} (used in the [[Fiat Punto]], [[Fiat Panda|Panda]], [[Fiat Palio|Palio / Albea]], [[Fiat Idea]], [[Opel Corsa|Opel Corsa / Combo]], [[Opel Meriva]] and [[Suzuki Swift]]), a variable inlet geometry {{Auto PS|90}} (used in the new [[Fiat Grande Punto]], [[Fiat Linea]], [[Opel Corsa]] and [[Opel Astra]]), and a {{Auto PS|105}} is available to Lancia Ypsilon. At the time of the launch this was the smallest four-cylinder diesel engine available and has a fuel consumption of {{convert|3.3|L/100 km|abbr=on}} in some applications. The engine is able to meet [[Euro IV]] pollution standards without the use of a [[diesel particulate filter]].
The intake manifolds, cylinder head castings, and other basic engine components are capable of supporting much higher power than factory-equipped engines produced. Even more readily than the typical Gen 1 small block, these aspects of the LT1 and LT4 enable their horsepower to be significantly increased by the addition of high-performance air intake ducting and exhaust systems. Further, upgrading the cylinder head porting and camshaft design with appropriate supporting modifications can enable these engines to produce in excess of 400 naturally aspirated horsepower at the rear wheels, or about {{Convert|500|hp|kW|-1|abbr=on}} at the flywheel. General assumptions for friction loss through the drivetrain are as follows: 10%-12% friction loss for manual 6-speed transmissions, and 15%-20% for automatic transmissions.  


===LT1===<!-- This section is linked from [[Chevrolet Corvette]] -->
In January 2008 [[Tata Motors]] introduced new [[Tata Indica|Indica V3]] model, which features new '''Quadra-Jet''' branded version of this engine.<ref name="tata.com">{{Cite web|url=http://www.tata.com/tata_motors/releases/20080109.htm|title=Tata Motors launches new vehicle models at the New Delhi Auto Expo|accessdate=2008-01-10|work=tata.com}}</ref>
[[Image:1993ChevroletCamaroZ28-003.jpg|thumb|right|250px|GM LT1 from a 1993 [[Chevrolet Camaro]] Z28.]]
In 1992, GM created a new-generation small-block engine called the '''LT1''', recalling the 1970 [[GM Small-Block engine#LT-1|LT-1]] moniker. It displaced {{Auto Lrev|350}} and was a 2-valve [[pushrod engine|pushrod]] design. The LT1 used a reverse-flow cooling system which cooled the cylinder heads first, maintaining lower cylinder temperatures and allowing the engine to run at a higher compression than its immediate predecessors.

There were a few different versions of the LT1. All feature a cast iron block, with aluminum heads in the Y and F bodies, and cast iron heads in the B and D bodies. Corvette blocks had four-bolt main caps, while most other blocks were two-bolt main caps.
applications:
*[[Alfa Romeo Mito]]
*[[Fiat Bravo/Brava#Second generation|Fiat Bravo]]
*[[Fiat Grande Punto]]
*[[Fiat Idea]]
*[[Lancia_Delta#Third_generation|Lancia Delta]]
*[[Lancia Musa]]


The 92-93 LT1s used speed density fuel management, batch-fire fuel injection and a dedicated engine control module (ECM). In 94 the LT1 switched to a [[mass airflow sensor]] and [[Fuel_injection#Multi-point_fuel_injection|sequential port injection]]. A new, more capable computer controlled the transmission as well as the engine and got a new name: powertrain control module (PCM). Where the ECM held its calibration information in a replaceable chip, the PCM was reprogrammable through the diagnostic port.
==1.9==
The most common JTD engine is the 1.9&nbsp;L (1910&nbsp;cc) [[straight-4]] found in the [[Fiat Punto]], [[Fiat Doblò|Doblò]], [[Fiat Stilo|Stilo]] and [[Fiat Croma|Croma]].


The early Opti-spark [[distributor]] had durability problems and a revised version was introduced on the 1994 B-Bodies and in 1995 on the Y and F-Bodies. 1996 saw major revisions for [[OBD-II]] - a second catalytic converter on the F-body cars and rear oxygen sensors to monitor catalyst efficiency. Some OBD-II features had been added to the Corvette starting in 1994 for testing purposes.{{Fact|date=September 2008}} The 1997 model year Camaro and Firebird were the last year for this engine in a GM production car.  
The first car that used this engine was [[Alfa Romeo 156]] in 1997 ({{Auto PS|105}}), making it the world's first common-rail Diesel passenger car. In 1999 it was introduced with the [[Fiat Punto]] and [[Fiat Brava]]/[[Fiat Bravo]]/[[Fiat Marea]]. The engine block weighs approximately {{convert|125|kg|lb|0|abbr=on}}.


The 1992 LT1 in the Y-body was factory rated at {{Convert|300|hp|kW|-1|abbr=on}} and {{Auto lbft|330}}. 96 LT1 Y-bodies were rated at {{Convert|300|hp|kW|-1|abbr=on}} and {{Auto lbft|340}}. The 93-95 F-bodies were rated at {{convert|275|hp|kW}} and {{Auto lbft|325}}, while the 96-97 cars were rated at {{convert|285|hp|kW}} and {{Auto lbft|335}}.
The Multijet second generation features a common-rail design and is available with four different power outputs. The 8-valve version has {{auto PS|100}}, {{auto PS|120}} or {{auto PS|130}}, the last two with [[variable geometry turbocharger|variable inlet geometry]]; and the 16-valve version has {{auto PS|150}}.
The 96-97 WS6 and SS F-bodies were rated at {{Convert|305|hp|kW|0|abbr=on}}. The 94-96 B and D-body version was rated at {{convert|260|hp|kW}} and {{Auto lbft|330}}.


===LT4===<!-- This section is linked from [[Chevrolet Corvette]] -->
[[Opel]] also uses a version of this engine. Their '''CDTI''' engine, manufactured in [[Pratola Serra]], [[Italy]] and [[Kaiserslautern, Germany]], is the product of the half-decade joint venture between GM and Fiat. It is used in the [[Opel Vectra|Vectra]], [[Opel Signum|Signum]], [[Opel Astra|Astra]], [[Opel Zafira|Zafira]], [[Cadillac BLS]] and [[Suzuki SX4]] as well as some [[Saab Automobile|Saabs]] marked as '''TiD''' and '''TTiD''' (twinturbo version).
The '''LT4''' was a special high-performance version of the new-generation LT1. With the addition of a slightly more aggressive camshaft profile, 1.6:1 roller aluminum rocker arms and better-flowing intake manifold (painted red) and cylinder heads, it was rated at {{convert|330|hp|kW}} and {{Auto lbft|340}}. It was introduced in the 1996 model year, for the last year of the C4 Corvette, and came standard on all manual transmission (ZF 6-speed equipped) C4 Corvettes. The engine was passed down to special versions of the Camaro and Firebird the next model year.


The LT4 was available on the following vehicles:
applications:
* 1996 [[Chevrolet Corvette]] when equipped with 6-speed manual transmission (includes all Grand Sports) (Production: 6,359)
*[[Alfa Romeo 145]]
* 1997 [[Chevrolet Camaro]] SLP/LT4 SS 6-speed (Production: 100 for the U.S., 6 for Canada.  There were 2 prototypes)
*[[Alfa Romeo 146]]

==LT5==<!-- This section is linked from [[Lotus Cars]] -->
===1.9 Twin Turbo===
[[Image:GMLT5.JPG|thumb|right|250px|A GM LT5 engine]]
[[Image:1.9 TT Multijet.jpg|right|thumb|250px|Engine cover of Lancia Delta´s 1.9 TT Multijet.]]
Immediately prior to the release of the second generation small block, General Motors released a largely unrelated engine which also used the LT name. The LT5 was engineered by a team headed by Terry D. Stinson.{{Fact|date=September 2008}} It was an all-aluminum {{Auto Lrev|349}} small-block V8, but was entirely different from any of the other Chevrolet 350 engines. The bore and stroke were both different at 3.9 by 3.66 in (99 by 93 mm) instead of the usual 4 by 3.48 in (102 by 88 mm) and it featured [[Lotus Cars|Lotus]]-designed 32-valve [[DOHC]] heads. It was hand built by specialty engine builder, [[Mercury Marine]]. This engine produced {{convert|375|hp|kW}} and {{Auto lbft|370}} for the 1990-1992 [[Chevrolet Corvette C4#ZR-1|Corvette ZR-1]] and jumped to {{convert|405|hp|kW}} and {{Auto lbft|385}} for 1993 to its final year in 1995, thanks to cam timing changes and improvements to the engine porting. 1993 also added 4-bolt main bearing caps and an exhaust gas recirculation system. The engine was not used in any other vehicle.
Fiat Powertrain Technologies released information about new twin stage turbo (twin turbo) version of this engine in summer 2007, engine is available with two power levels, first one is producing {{Auto PS|180}} and second one {{Auto PS|190}}, both have a maximum torque output of {{Auto Nm|400}} at 2000 rpm. 180&nbsp;PS version production started summer 2007. The engine weights approximately {{convert|185|kg|lb}}. This engine will be sold both to Fiat Group Automobiles and other brands, but the {{convert|190|PS|kW hp|0|abbr=on}} version is reserved only to Fiat Group Automobiles.<ref name="fptpowertrain.com">{{Cite web|url=http://www.fptpowertrain.com/eng/pdf/Comunicato_uk.pdf|format=PDF|title=Press release:NEW ENGINE 1.9 JTD TWIN STAGE TURBO|accessdate=2007-06-08|work=fptpowertrain.com}}</ref>


===L99 (4.3L)===
applications:
A 4.3L (263in<sup>3</sup>) version of the LT1, designated the '''L99''', was introduced in 1994 for the [[Chevrolet Caprice]]. It was externally identical to the LT1, but the bore was reduced to {{convert|3.736|in|mm}} and the stroke to {{convert|3|in|cm}}, giving it a displacement of 263&nbsp;in<sup>3</sup>. The pistons used in the L99 were the same as the ones used in the [[GM Vortec engine#5000|Vortec 5000]], and {{convert|5.94|in|mm}} connecting rods were used.
*[[Cadillac BLS]]
*[[Lancia Delta]]
*[[Saab 9-3]]


Like the LT1, it features sequential [[fuel injection]], [[reverse cooling]], and an optical crank position sensor. Output is {{Convert|200|hp|kW|-1|abbr=on}} and {{Auto lbft|245|0}}. Due to its smaller displacement, it provides better fuel economy than the 5.7&nbsp;L LT1.
==2.0==
A new 2 litre (1956 cc) Multijet diesel was introduced in third generation Lancia Delta in summer 2008. At its first version this engine produces {{convert|165|PS|kW bhp|abbr=on}}.

===2.0/2.2 (PSA)===
The 2.0 JTD (1997 cc), used on Fiat Scudo, is not actually a Fiat engine, but rather a rebadged [[PSA EW/DW engine#DW10|PSA DW10]] engine.


[[it:GM Serie LT]]
The related 2.2 M-JET (2179 cc) used on Lancia Phedra and Fiat Ulysse is rebadged version of [[PSA EW/DW engine#DW12|PSA DW12 engine]], it produces {{convert|130|PS|kW|0|abbr=on}}. In January 2008 was introduced a new version with {{convert|170|PS|kW|0|abbr=on}}.

==2.4==
[[Image:Alfa0038.jpgJTD.jpg|right|thumb|250px|Engine cover of Alfa Romeo 166 2.4 JTD.]]
 
The 2.4&nbsp;L (2387&nbsp;cc) [[straight-5]] version is based on the 2.4 {{Auto PS|124}} 5 cylinder TD engine as used in the Mk1 Fiat Marea. The JTD version benefits from the solid build of the TD block, and an improved head/injection system. There are 2 versions of the 2.4JTD, the 10-valve as used in the [[Fiat Marea]] 130 JTD and the earlier [[Alfa Romeo 156]] diesels where it was available as {{Auto PS|136}},{{Auto PS|140}}, {{Auto PS|150}} and later a 20-valve version {{Auto PS|175}} as used in the later (2003>) [[Alfa Romeo 156]] as well as some [[Lancia]] vehicles.
 
It was designed for [[transverse engine|transverse]] [[front-wheel drive]] use and was deemed too long and tall for widespread use in other GM or Fiat products. The multijet variant of this engine, capable for {{Auto PS|200}}, is currently used in the [[Alfa Romeo 159]], [[Alfa Romeo Brera]] and [[Fiat Croma]]. The latest version of this engine produces {{Auto PS|210}} and {{Auto Nm|400}} at 1500 rpm, and is used in Alfa Romeo vehicles.<ref name="fiatautopress.com">{{Cite web|url=http://www.fiatautopress.com/index.php?l=2&group=3&method=cartelle&action=zoom&id=20070219122146cfc0a108ba13361870975eb76a776295|title=Alfa Romeo at the 77th Geneva International Motor Show 2007|accessdate=2007-06-09|work=fiatautopress.com}}</ref>

JTD (uniJet Turbo Diesel) is Fiat Group's term for its current common rail turbodiesel engine range. The MultiJet name is used in the second generation JTD common rail units. Most of the Fiat, Alfa Romeo and Lancia range has JTD engines. Ownership of some Fiat JTD designs is shared with General Motors as part of a settlement of the failed merger between the two auto conglomerates. GM Powertrain Europe group in Turin, Italy manages their interest in these engines. Some PSA Peugeot Citroën diesel engines are also rebadged as JTD. A new generation JTD engine, Multijet II is under development and will be available in 2009, the Fiat Powertrain Technologies sees its very important step in diesel technology. This new technology will be first available for the 1.3 litre JTD engine.[1]

1.3

A small 1.3 L (1248 cc) version (called the SDE, Small Diesel Engine) is produced in Bielsko-Biała, Poland. The Multijet 75 PS version was chosen in 2005 as the International Engine of the Year in the 1-litre to 1.4-litre category.

There are four versions of this engine: a 70 PS (69 hp/51 kW), a 75 PS (74 hp/55 kW) (used in the Fiat Punto, Panda, Palio / Albea, Fiat Idea, Opel Corsa / Combo, Opel Meriva and Suzuki Swift), a variable inlet geometry 90 PS (89 hp/66 kW) (used in the new Fiat Grande Punto, Fiat Linea, Opel Corsa and Opel Astra), and a 105 PS (104 hp/77 kW) is available to Lancia Ypsilon. At the time of the launch this was the smallest four-cylinder diesel engine available and has a fuel consumption of 3.3 L/100 km (86 mpg-imp; 71 Template:Convert/fourmregb) in some applications. The engine is able to meet Euro IV pollution standards without the use of a diesel particulate filter.

In January 2008 Tata Motors introduced new Indica V3 model, which features new Quadra-Jet branded version of this engine.[2]

A 1.6 L (1598 cc) version of the engine, with a maximum power output of 120 PS (118 hp/88 kW) was announced for 2006.[3] The new 1.6 JTD diesel (105 PS) was released December 2007, it came in spring 2008 as 120 PS version.[4]

applications:

  • Alfa Romeo Mito
  • Fiat Bravo
  • Fiat Grande Punto
  • Fiat Idea
  • Lancia Delta
  • Lancia Musa

1.9

The most common JTD engine is the 1.9 L (1910 cc) straight-4 found in the Fiat Punto, Doblò, Stilo and Croma.
