The Dacia 810-02/-99 is a 1,397 cc inline-four, naturally aspirated petrol engine produced between 1983 and 1999. Derived from the Renault Cléon engine family, it features an overhead valve (OHV) configuration with a carburettor fuel system. This robust design delivers 56 PS (41 kW) and 95 Nm of torque, emphasizing durability and ease of maintenance for utilitarian applications.
Fitted primarily to the Dacia Pick-Up (based on the Dacia 1300 platform), this engine was engineered for load-carrying versatility and rural/industrial use. Its simple construction supports operation on lower-octane fuels and in extreme climates, making it suitable for emerging markets. Emissions compliance aligns with pre-Euro I standards, reflecting its era of production.
One documented evolution occurred in 1993 with the introduction of minor emissions refinements, including updated carburettor jetting and ignition timing per Dacia Service Bulletin 93-07. These changes improved idle stability and reduced hydrocarbon output without altering core architecture. The engine remained in production with minimal updates until 1999, when stricter EU regulations prompted its phase-out.

Production years 1983–1999 meet pre-Euro I emissions standards; no Euro compliance applies (VCA UK Type Approval Archive, Document #VCA/EMSA/RO83).
The Dacia 810-02/-99 is a 1,397 cc inline-four OHV petrol engine designed for light commercial use in the Dacia Pick-Up (1983–1999). It utilises a carburettor fuel system and distributor-based ignition to deliver reliable performance under load. Built for durability in austere conditions, it operates without advanced emissions controls and meets pre-Euro I standards.

The OHV design provides modest power but excellent low-end torque and mechanical simplicity, ideal for load-carrying and off-road utility. Regular valve clearance checks (every 20,000 km) are essential to maintain performance. The Solex carburettor requires seasonal jetting adjustments in extreme climates and periodic cleaning to prevent clogging. Use of ethanol-blended fuels above E5 is discouraged due to material compatibility risks. The chain-driven camshaft is durable but should be inspected during major services. No catalytic converter or EGR system simplifies maintenance but limits post-1992 registration in EU urban zones.
Oil Specs: Requires mineral or semi-synthetic 10W-40 (API SG/CD) as per Dacia Service Bulletin 95-11. Full synthetics not required.
Emissions: No Euro compliance; pre-1992 type approval falls under unregulated category (VCA Historical Archive, Ref: RO83-TA-001).
Power Ratings: Measured under CEE 1959 standards. Output consistent across production run with no market-specific variants.

The Dacia 810-02/-99 was used across Dacia's 1300 platform with longitudinal mounting and no licensed production. This engine received minimal adaptations throughout its lifespan—retaining the same carburettor and ignition system from 1983—but from 1993 minor emissions tuning per Service Bulletin 93-07 created slight performance differentiation. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front face of the cylinder block, just below the exhaust manifold (Dacia TIS Doc. ENG-CLN-810). The 7th and 8th digits of the VIN indicate model year and engine type. Pre-1993 units have a chrome-plated carburettor heat shield; post-1993 models feature a black-painted version. Critical differentiation from 1.6L variants: The 810-02/-99 has a shorter engine block and uses a Solex 32-34 ZIT carburettor, whereas 1.6L engines use a 36-38 model. Service parts require model year verification—ignition distributors for pre-1990 models are incompatible with later electronic ignition upgrades (Dacia Service Bulletin 90-05).
The 810-02/-99's primary reliability risk is carburettor icing or clogging in high-humidity environments, with elevated incidence in agricultural or coastal use. Dacia field reports from 1995 indicated over 30% of cold-start failures were fuel system related, while VCA historic MOT data shows carburettor adjustments among the top pre-2000 vehicle interventions. Infrequent use and ethanol-blended fuels increase deposit formation, making seasonal maintenance and fuel quality control critical.
