Chronology
Predecessor Z series

The Nissan NA family of straight-four engines is a series of engines manufactured by Nissan (Nissan Machinery). It is the replacement of the Z series, on which its design is based, and is mostly used in commercial vehicles due to its use of Liquefied petroleum gas for fuel on engines with a "P" suffix code. It is entirely unrelated to the 1950's NAK engine.

Applications

NA20P

In 1998 the NA20P was updated, with redesigned combustion chambers which increased power and torque while lowering fuel consumption. A new catalyst reduced emissions, making it the first LPG-engined passenger car to be designated a low-pollution vehicle in several Japanese cities and prefectures. [2]

Applications

NA20PE

This fuel injected, LPG-powered variant was introduced in September 2010 and met new, stricter emissions regulations.
