The Chrysler 1.8, 2.0, and 2.4 are inline-4 engines designed originally for the Dodge and Plymouth Neon compact car. These engines were loosely based on their predecessors, the Chrysler 2.2 & 2.5 engine, sharing the same 87.5 mm bore. The DOHC head was developed by Chrysler with input from the Chrysler-Lamborghini team that developed the Chrysler/Lamborghini Formula 1 V12 engine in the early 1990s.
Beginning in 2005, these engines were phased out in favor of the new World engine built by the Global Engine Manufacturing Alliance joint-venture.
The 2.0 and 2.4 variants were built at Saltillo Engine in Ramos Arizpe, Coahuila, Mexico. The 1.8 and 2.0 was also built at Trenton Engine in Trenton, Michigan, United States.
The EBD, is a 1,796 cc (109.6 cu in) under-bored variant of the 2.0 L engine. This engine features a square 83 mm (3.3 in) bore and stroke with a 10.0:1 compression ratio. This engine was built at the Trenton Engine Plant for use in export market (non-US) Chrysler Neons. It produces 86 kW (115 hp) at 5750 rpm and 151 newton metres (111 lb·ft) at 4950 rpm and meets Euro III emission standards.
Applications:
The 1,996 cc (1.996 L; 121.8 cu in) version of the 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 16-valve versions (4 valves per cylinder). 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 engine speeds. 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 timing belt is used to drive the valvetrain. Early production 2.0 L engines used a hydraulic tensioner to tension the timing belt. 2000 and 2001 engines used a mechanical spring-loaded tensioner that tended to wear out prematurely, causing serious valve and piston damage upon belt failure due to the interference design of the engine. 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.
