The CG engine is a 1.0 L, 1.3 L or 1.4 L straight-4 piston engine from Nissan. It is an aluminum DOHC 16-valve design. The engine was developed for use in the Nissan Micra/March K11 series. All engines featured multi-point fuel injection. Redline is at 7300 rpm.
This compact, reliable, lightweight and fuel-efficient motor has also found life in many Nissan Forklift models.
The breakdown of the engine code is as follows:
- CG - Clean Green
- 10, 13 or A3 - 1.0, 1.3 or 1.4 Litres
- D - Double Overhead Cam (DOHC)
- E - Multi-port Fuel Injection
The 1.0 L (998cc) CG10DE was built from the introduction of the Nissan Micra K11 in January 1992  until it was replaced by the K12 series in 2002. The engine originally produced 58 PS (43 kW) @6000 rpm and 79 Nm @4000 rpm. In 2000, Nissan removed the distributor and replaced it with coil packs & increased the compression ratio from 9.5:1 to 9.8:1, increasing the reliability, efficiency and performance of the engine to 60 PS (44 kW) @6000 rpm and 84 Nm @4000 rpm.
The 1.3 L (1275cc) CG13DE was built from 1992  and continues to power the current (2007) model K11 in Taiwan. The engine produces 79 PS (58 kW) and 105.91 N·m (78.12 lb·ft) @4000 rpm. In 2000 it was replaced by the CGA3DE in most countries.
The 1.4 L (1348cc) CGA3DE was built between November 1999 and 2002. The engine produced 85 PS (63 kW) @6000 rpm and 120 N·m (89 lb·ft) @4000 rpm. This engine, although considered a 1.4 in the European market, was still marketed as a 1.3 engine in Japan due to the cubic capacity being 1,348 cc. The x-alpha spec Z10 Nissan Cube was made from May 2001 to September 2002. It's CGA3DE produced 101 PS (74 kW) @ 6400 rpm and 12.5 kg*m (123 Nm) @ 4400 rpm, CR 10:1. In October 2002 the CG engines were replaced with CR engines in Japan.
