Nissan Z engine
Encyclopedia
The Nissan Z series of automobile
engines ranged from 1.6 L to 2.4 L and were produced from 1979 through August 1989. The Z series engines retained a nearly identical block to the earlier L Series
with the exception of the Z24 which utilized a taller deck height to increase engine displacement
. All Z engines were SOHC. The most notable feature of the Z-Series engine was the introduction of the crossflow cylinder head
which increased performance and reduced emissions
by moving the intake ports to the right side of the vehicle opposite the exhaust ports. This change allows the fuel
air mixture to more easily enter the combustion chamber
and also allows the exhaust port velocity to more effectively scavenge the cylinder and reduce reversion pulses. The Z series were replaced with the Nissan KA
and NA
engines.

In the US, the Z20S was only available in the 1980-81 510/A10.
The Nissan Caravan and Homy with this engine produced a maximum speed of 160 km/h. It was noted for being faster than its competitor Toyota Hiace, primarily because Z20S produced more power than the engines available in the Hiace.

Note: All Z20, Z22 and Z24 engines were known as NAPS-Z (NAPZ or NAPEZ) engines, NAPS for Nissan Anti-Pollution System. NAPZ motors had dual sparkplugs per cylinder except the pre-82 versions and later versions of the Z24 as fitted to the Pathfinder. However all NAPZ engines sold in California reportedly had dual plug heads regardless of the year.
The fuel injected version referenced above was denoted as the Z24i (Throttle Body Fuel Injection) and was first available in the Nissan Model 720 ST pickup during the 1985 model year and was replaced in 1990 by the KA24E
engine. Beside the fuel injection, a significant change for the Z24i was the addition of an optical crank angle sensor in the distributor rather than a vacuum advance and ignition module. This allowed for more precise engine management for the fuel injection system.
