The Nissan CA18 engine is an in-line 4-cylinder gasoline engine and LPG engine developed and manufactured by Nissan Motors from 1981 to 1993. 

History

As a successor to the Z-type engine, it was installed in passenger cars and commercial vehicles. The initial SOHC head specification was positioned as a direct successor engine to the Z type the SOHC head specification used twin plugs (per cylinder), and the DOHC head specification used direct ignition as the ignition system. The fuel supply system is combined carburettor  and this electronically controlled engine was later given the nickname Plasma or a Nissan ECCS controlled fuel injection system., inheriting the technology of the twin plug rapid combustion mechanism and given the nickname NAPS-X. Using computer analysis, it is 35kg lighter than the Z18 engine. 

This CA type Engine is the first DOHC engine in Nissan's Front engine front wheel drive car. The diesel of the same generation is the CD engine, and the successor is the SR engine.

Production for the CA type Engine has now ended.
