The CG engine is a 1.0 L, 1.3 L or 1.35 L straight-4 piston engine from Nissan's Aichi Kikai division. 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 1.35 Litres
D - Double Overhead Cam (DOHC)
E - Multi-port Fuel Injection

CG10DE

The 1.0 L (998 cc) CG10DE was built from the introduction of the Nissan Micra K11 in January 1992^[1] ^[2] until it was replaced by the K12 series in 2002.

CG13DE

The 1.3 L (1,275 cc) CG13DE was built from 1992^[1] ^[2] and continues to power the current (2007) model K11 in Taiwan.^[3] In 2000 it was replaced by the CGA3DE in most countries.

CGA3DE

The 1.3 L (1,348 cc) CGA3DE was built between November 1999^[4] 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 1.3 L (1,348 cc). The x-alpha spec Z10 Nissan Cube was made from May 2001 to September 2002.

In October 2002 the CG engines were replaced with CR engines in Japan.^{[citation needed]}
