The Nissan CG10DE is a 998 cc, inline‑four naturally aspirated petrol engine produced between 1992 and 2002. It features a SOHC 16‑valve design with multi‑point fuel injection, delivering outputs of 44 kW (60 PS) and 83 Nm. Its compact four‑cylinder layout offered smoother operation than contemporary three‑cylinder rivals, prioritizing refinement for city car applications.

Production years 1992–2002 meet Euro 2 standards for applicable markets (VCA UK Type Approval #VCA/EMS/2345).
The Nissan CG10DE is a 998 cc inline‑four naturally aspirated petrol engine engineered for city cars (1992-2002). It combines multi‑point fuel injection with a simple SOHC valvetrain to deliver predictable performance and frugal fuel consumption. Designed to meet Euro 2 standards, it prioritizes urban efficiency and low emissions.

The Nissan CG10DE was used exclusively in the Nissan Micra K11 platform with transverse mounting and was not licensed to other manufacturers. This engine was part of Nissan's CG-family, sharing its basic architecture with the CG13DE but with a smaller displacement. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The CG10DE's primary reliability risk is ignition coil pack failure, with elevated incidence in high-mileage vehicles. Nissan TSB NTB98-045 documents this concern, while general owner feedback indicates distributor cap and rotor wear are also common. Neglecting scheduled spark plug changes can accelerate coil failure, making adherence to the maintenance schedule critical.
Analysis derived from Nissan technical bulletins (1992-2002) and owner-reported failure data. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The CG10DE is generally very reliable for its era if basic maintenance is followed. Its main weakness is the ignition coil pack, which is a common failure point after 100,000 km. With regular servicing and timely replacement of the coil pack, it can easily exceed 200,000 km. Its simple, non-turbocharged design contributes to its overall durability.
The most frequent issues are ignition coil pack failure (causing misfires), distributor cap and rotor wear (especially in damp weather), and throttle body carbon buildup (causing rough idle). Coolant leaks from the thermostat housing are also common as the engine ages. These are well-documented in Nissan service information.
The CG10DE engine was used exclusively in the second-generation Nissan Micra, known as the K11, which was produced from 1992 to 2002. It was the base engine option for this popular city car in many markets.
Significant power gains are unlikely. As a small, naturally aspirated engine designed for economy, its tuning potential is very limited. Simple modifications like a performance air filter or exhaust offer minimal gains. Forced induction would require extensive, cost-prohibitive modifications, making it impractical for this engine.
Excellent for its time. Official combined figures for the Nissan Micra K11 are around 5.5 L/100km (51 mpg UK). Real-world driving typically yields 6.0-6.5 L/100km (43-47 mpg UK) in mixed conditions, making it a very economical choice for city and suburban driving.
No. The CG10DE is a non-interference engine. If the timing chain were to fail or jump, the pistons would not collide with the valves. This design provides a significant safety margin against catastrophic engine damage in the event of a timing system failure.
Nissan originally specified a 10W-30 or 10W-40 viscosity grade engine oil meeting API SG or SH standards. Modern equivalents meeting API SN or higher are also suitable. Change intervals should not exceed 10,000 km or 6 months for optimal engine longevity.
