Chrysler Neon engine 861555 223172662 2008-07-02T21:57:30Z SpellingBot 6773085 seperate → separate, seperates → separates The '''Chrysler Neon engine''' is a small [[straight-4]] [[piston engine]] designed originally for the [[Dodge Neon|Dodge and Plymouth Neon]] [[compact car]]. It was loosely based on the [[Chrysler K engine]] and the [[Rover K engine]], sharing the same 87.5&nbsp;mm bore. The [[SOHC]] cylinder head on the 2.0 is similar to that on [[Mitsubishi Motors|Mitsubishi]]'s [[Mitsubishi Orion engine|"Orion" 4G15B]], and the [[DOHC]] head from the 2.0 and 2.4 is similar to Mitsubishi's [[Mitsubishi Sirius engine|"Sirius" 4G63B]]. The DOHC head was deveolped by Chrysler with input from the Chrysler-Lamborghini team that developed the Chrysler/Lamborghini Formula 1 V12 engine in the early 1990s<ref name="HPM Article">{{cite journal | author=McCraw, Jim| title=The Chrysler/Lamborghini Formula 1 V12: REVS R US!| journal=High Performance Mopar| year=1993| volume=7| issue=7| pages=50–55}}</ref>. The Neon engine itself is the loose basis for the [[Tritec engine]]. Beginning in 2005, the Neon engine began phasing out in favor of the new [[Global Engine Manufacturing Alliance]] joint-venture engine. The 2.0 and 2.4&nbsp;L variants were built at [[Saltillo Engine]] in [[Ramos Arizpe]], [[Coahuila]], [[Mexico]]. The 2.0 was also built at [[Trenton Engine]] in [[Trenton, Michigan]]. ==1.8== A 1.8 (1796&nbsp;cc)&nbsp;L variant is made in the [[Trenton, Michigan]] engine plant for export (non-US) [[Chrysler Neon]]s. It produces 115&nbsp;[[Horsepower|hp]] [[DIN]] (85&nbsp;kW) and 112&nbsp;ft·lbf (152&nbsp;N·m) and meets [[Euro III]] standards. ==2.0== The 2.0&nbsp;L (1996&nbsp;cc) version of the Neon engine, was the first offered. Production began in 1994 in [[Trenton, MI]], and it was used in many [[Chrysler Corporation]] vehicles. It is available in both SOHC and DOHC 4-valve versions.The engine features a cast-iron block, with pistons with shallow crowns to save weight. The block uses a bedplate featuring a perimeter wall with transverse webbings for durability and quiet operation at high RPM's. The pistons are attached to fracture-split forged powdered metal connecting rods using semi-floating press-fit pins. A gerotor oil pump is driven directly from the crankshaft on the front of the engine. A reinforced rubber timing belt is used to drive the valvetrain. Early production 2.0&nbsp;L engines used a hydraulic tensioner to tension the timing belt. 2000 and 2001 engines received a mechanical spring-loaded tensioner that tended to wear out prematurely, while 2002+ engines utilized a different mechanical tensioner. The water pump is driven from the timing belt, with the water pump housing cast partially into the engine block itself. 1995 model year engines had two features that set them apart from later model year engines. The positive crankcase ventilation (PCV) system utilized a plastic oil separator box that was vented directly to the block itself; the breather hose and [[PCV valve]] hoses attached to the box, and connected to the induction system. Later model year engines featured a PCV system that was molded to the cylinder head valve cover. The second feature was internal in nature - the crankshaft main bearings were keyed into the bedplate on the right rear of each transverse web. Later model years featured keys machined on the right front of each web. These considerations are important when considering a rebuild or replacement of this engine in a given vehicle. 2002 and earlier model year engines featured a one-piece cast nodular iron crankshaft with counterweights present on either side of each crank pin. A crankshaft tone wheel was present between number 1 and number 2 connecting rod pins, and was machined such that a Hall-effect magnetic pickup mounted to the engine block could read the position of the crankshaft as it rotates during normal operation. 2003 and later model year engines switched to a two-piece crankshaft. The tone wheel was re-engineered to attach to the crankshaft using three bolts, had a tone pattern that was substantially different from previous model year engines, and was moved to the rear of the crankshaft. For this reason, these engines are generally not interchangeable between the 2002- and 2003+ model years. Up to late 1999, this engine type suffered from oil leaks between the block and cylinder head. The threads for the head bolts near the 4th cylinder were bored too shallow at the factory, preventing the head from properly sealing. The oil restrictor in the composite gasket would separate from the gasket causing a leak. Chrysler Corporation used several different designs of composite material head gasket in an attempt to solve this problem. In 1998, a thicker multi-layer steel head gasket was introduced that eliminated this oil leak. It can be identified by a small metal tab with a hole through its center sticking out between the block and head between the 2nd and 3rd cylinders. ;General Specifications *Number of Cylinders: 4 *Cylinder Configuration: In-line *Number of Valves: 16 (4 per cylinder) *Fuel Delivery: Sequential Multi-Port [[Fuel Injection]] *Bore: 87.5&nbsp;mm (3.44&nbsp;in) *Stroke: 83.0&nbsp;mm (3.27&nbsp;in) *Displacement: 2.0&nbsp;L (1996&nbsp;cc or 122&nbsp;cid) *Redline: 6500&nbsp;rpm *Rev Limiter: 6750&nbsp;rpm ===A588=== The A588 is the [[SOHC]] version. Output is {{convert|132|hp|abbr=on}} [[SAE]] (98&nbsp;kW) at 5600&nbsp;rpm with 130&nbsp;ft·lbf (177&nbsp;N·m) of torque at 4600&nbsp;rpm. It has an aluminum SOHC cylinder head. It uses a reinforced plastic intake manifold (although a few of the 1995 & 1996 engines received an aluminum intake manifold due to a shortage of the plastic parts). They were painted black, but it's easy to see the casting marks and prints on the manifold. The aluminum version is much prized among enthusiasts as it's easy to port and polish for increased flow characteristics. Applications: * [[Dodge Neon]]/[[Plymouth Neon]] (1995-2005) * [[Dodge Stratus]] (1995-2000) * [[Plymouth Breeze]] (1996-2000) ;Specifications *Compression Ratio: 9.8:1 *Camshaft Configuration: [[SOHC]] *Power: {{convert|132|hp|abbr=on}} @ 5600&nbsp;rpm *Torque: {{convert|130|ft.lbf|N.m|abbr=on}} @ 4600&nbsp;rpm ===Magnum=== The Magnum SOHC version, code ECH, develops {{convert|150|hp|abbr=on}} [[SAE]] (111&nbsp;kW) at 6500&nbsp;rpm, and 135&nbsp;ft·lbf (184&nbsp;N·m) of torque at 4800&nbsp;rpm. Chief differences between this version and the A588 include a cast aluminum SOHC cylinder head that more easily passes exhaust gases than the base engine, a camshaft that is optimized for higher engine RPM's, a factory welded exhaust short-tube [[Manifold (automotive engineering)|header]] in lieu of a cast exhaust manifold, and a two-piece intake manifold. This manifold features unequal-length intake runners that are switched during engine operation by an electric actuator that controls butterfly-type valves in the shorter intake runners. The longer runners are always open, and provide a mild supercharging effect due to their length between 3000&nbsp;rpm and 4800&nbsp;rpm. The shorter runners, open from 4800&nbsp;rpm to redline at wide-open throttle, also provide a tuned resonance effect due to their length. The shorter runners are also opened at wide-open throttle below 3000&nbsp;rpm to provide an intake path to each cylinder that is as free-flowing as possible.

It has a cast iron engine block and aluminum DOHC cylinder heads. It uses SFI [[fuel injection]], has 4 valves per cylinder with roller rocker arms and features fracture-split forged powder metal connecting rods, a one-piece cast camshaft, and an aluminum intake manifold. The version used in the [[Chrysler PT Cruiser]] and [[Dodge Neon]] features a cylinder head with the intake ports facing the front of the vehicle, like the [[SOHC]] A588. Versions ([[420A]]) used in the dodge-designed chassis, such as the [[Dodge Avenger]] and [[Mitsubishi Eclipse]], have the intake ports facing the rear of the vehicle. Most other specifications are identical, however, and even some head components (such as the rocker cover) are compatible.

It also uses [[balance shaft]]s to smooth vibrations and is built in [[Saltillo, Mexico]]. Output was up to {{convert|140|hp|abbr=on}} when production started in 1994 for the 1995 model year. As of 2004, output is {{convert|152|hp|abbr=on}} SAE (110&nbsp;kW) at 5200&nbsp;rpm with 165&nbsp;ft·lbf (224&nbsp;N·m) of torque at 4000&nbsp;rpm. It has a cast iron engine block and an aluminum DOHC cylinder head. It uses SFI [[fuel injection]], has 4 valves per cylinder with roller followers and features fracture-split forged powder metal connecting rods, a one-piece cast camshaft cast, and an aluminum intake manifold. Like it's smaller 2.0L counterpart, the 1995-99 2.4L suffers from head gasket failures around the oil passage restricter intergral to the composite cylinder head. The Restricter typically separates from the gasket causing a leak. A Multi-Layer Steel (MLS) gasket was developed to remedy this issue. A very rare few 2000-2001 2.4L's with the MLS gasket have developed oil leaks. Other common leak points are the Camshaft oil seals and the Camshaft Position Sensor O-ring. An oil leak issue with the front crankshaft seal has developed in some 2004-2007 engines due to excessive crankshaft end-play. The excessive movement of the crankshaft pushes the seal out causing a leak.

Output is {{convert|230|hp|abbr=on}} SAE (172&nbsp;kW) at 5300&nbsp;rpm with 250&nbsp;ft·lbf (339&nbsp;N·m) of torque at 2200-4400&nbsp;rpm. The engine, code A855, has a cast iron closed deck block and split crankcase. It uses an 8.1:1 compression ratio with Mahle cast eutectic aluminum alloy pistons, forged connecting rods with cracked caps and threaded-in 9&nbsp;mm rod bolts, and a cast high-hardness steel crankshaft. The cylinder head is cast aluminum, with the cylinder heads being a 48-degree pent-roof design with a partial cloverleaf between the intake valves. The valves are actuated by hydraulically-adjusted rocker arms with roller cam followers. The [[Dodge SRT-4|SRT-4]] and [[Chrysler PT Cruiser|PT Cruiser Turbo]] use the same engine block and heads The intake manifold, turbo plumbing, and intercooler are all different. The cast-aluminum 8-row Valeo intercooler is mounted in the front, and the reverse-rotation Mitsubishi TD04LR-16Gk turbocharger has a 6 cm² turbine inlet. The turbocharger compressor housing features a built-in bypass valve, and the turbo housing is cast into the exhaust manifold with a loop-around flow pattern. The stock SRT-4 has a maximum boost level of 15psi Applications: * [[Chrysler PT Cruiser]] '''GT''' * [[Dodge SRT-4]] * [[Dodge Stratus]] '''R/T''' (Mexican) ==See also== * [[List of Chrysler engines]] ==External links== * [http://www.allpar.com/mopar/2.html The Chrysler 2.0 liter engine - used mainly in Neons] ==References== <references/> [[Category:Chrysler engines|Neon]]
