The Chrysler ECD is a 2,213 cc, inline‑four petrol engine produced between 1981 and 1983. It featured a single overhead camshaft (SOHC) design and two valves per cylinder, delivering modest outputs for its era. Equipped with a carburettor for fuel delivery, it produced approximately 75 kW (101 PS) and 162 Nm of torque, prioritising reliability and cost‑effective manufacturing over high performance.
Fitted primarily to the European‑spec Chrysler Horizon and Simca 1307/1308 models, the ECD was engineered for dependable, everyday commuting and light family use. Emissions compliance for its time was managed through basic engine tuning and the carburettor's design, meeting the prevailing Euro 1 standards without the need for complex after‑treatment systems.
One documented concern is premature wear of the timing belt tensioner pulley, which can lead to belt slippage or failure if not inspected. This issue, highlighted in Chrysler Service Bulletin TSB‑82‑07‑81, is often linked to the original pulley bearing design. The ECD was phased out after 1983 in favour of more modern and efficient engine designs.
Chrysler
Production years 1981–1983 meet Euro 1 standards as per the applicable regulations of the time (EU Directive 70/220/EEC).
The Chrysler ECD is a 2,213 cc inline‑four petrol engine engineered for compact hatchbacks (1981-1983). It combines a simple SOHC valvetrain with carburetted fuel delivery to deliver adequate power for urban and highway driving. Designed to meet Euro 1 emissions standards, it prioritised mechanical simplicity and owner affordability.

The carburetted fuel system provides straightforward maintenance but requires periodic adjustment and cleaning for optimal running. Timing belt replacement is critical at 60,000–80,000 km intervals to prevent catastrophic engine failure, as failure can cause valve damage. The original tensioner pulley (per Chrysler TSB 82-07-81) is prone to bearing wear; replacing it with an updated unit during belt service is strongly advised. Use of high-quality 10W-40 oil helps maintain engine longevity, particularly in older units where sludge buildup can be a concern.
Oil Specs: Requires SAE 10W-40 specification (Chrysler Owner's Manual 1982). API SF/CC or equivalent recommended.
Emissions: Euro 1 certification applies to all 1981–1983 models (EU Directive 70/220/EEC). No market-specific variations.
Power Ratings: Measured under SAE J1349 standards. Output is consistent across all model applications (Chrysler TIS Doc. ENG-81-01).

The Chrysler ECD was used across Chrysler's Horizon platform with transverse mounting. This engine received no major platform-specific adaptations during its short production run. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the front face of the cylinder block, just below the exhaust manifold (Chrysler TIS ENG-81-01). The code will read "ECD". Visually, it is identifiable by its single-barrel carburettor and distributor-based ignition system. Critical differentiation from the smaller ECA engine: The ECD has a larger displacement (2.2L vs 1.6L) and a visibly longer engine block. Service parts for the timing system require verification against the service bulletin TSB-82-07-81 for the correct tensioner pulley.
The ECD's primary reliability risk is timing belt system failure, with elevated incidence in high-mileage or poorly maintained examples. Chrysler service data indicates a significant number of failures occurring beyond the 80,000 km service interval, while owner reports frequently cite carburettor issues as a secondary concern. Neglecting the tensioner pulley update and extended service intervals make catastrophic engine damage likely.
