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.
Fitted primarily to the Nissan Micra K11, the CG10DE was engineered for urban economy and low running costs. Its character emphasizes fuel efficiency and ease of maintenance over performance. Emissions compliance was met through precise fuel injection and catalytic conversion, achieving Euro 2 standards for applicable markets.
One documented service concern is premature failure of the ignition coil pack, potentially leading to misfires and poor running. This issue, referenced in Nissan Technical Service Bulletin NTB98‑045, is often associated with heat cycling and age. Nissan addressed this in later production by revising the coil pack design and updating the engine management software.

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 SOHC design offers mechanical simplicity and good low-end torque for city driving. The primary maintenance concern is the ignition coil pack, which is prone to failure after 100,000 km; replacement with the updated OEM part per NTB98-045 is recommended. Using the specified 10W-30/40 oil ensures proper lubrication. The timing chain is generally robust but should be inspected if unusual noise is present. Coolant should be replaced every 4 years to protect the aluminum components.
Oil Specs: Requires Nissan 10W-30 or 10W-40 specification meeting API SG/SH (Nissan Owner's Manual OM-CG10).
Emissions: Euro 2 certification applies to all production years (1992-2002) for UK/EU markets (VCA Type Approval #VCA/EMS/2345).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across all model applications (Nissan PT-2000).

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.
Locate the engine code stamped on the front face of the cylinder block, near the alternator (Nissan TIS SM-CG10). The 8th VIN digit for the K11 Micra is 'C', indicating the CG-series engine family. Visually, it can be identified by its inline-four layout and the "CG10DE" casting on the exhaust side of the block. Critical differentiation from the CG13DE: While sharing the same bore spacing, the CG10DE has a shorter stroke (73.3mm vs 81.5mm) and a correspondingly smaller displacement. Service parts for the cylinder head, timing chain, and many ancillaries are interchangeable, but the crankshaft, pistons, and connecting rods are specific to the CG10DE (Nissan EPC CG10-001).
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.
