The '''Toyota NZ engine family''' is a [[straight-4]] [[piston engine]] series. The NZ series uses aluminium open deck [[engine block]]s and [[DOHC]] cylinder heads. It also uses sequential [[multi-point fuel injection]], and has [[Multi-valve#Four valves|4 valves per cylinder]] with [[VVT-i]].

The engines are produced by Toyota's Kamigo Plant in [[Toyota, Aichi]], [[Japan]];<ref name="Kamigo" /> by Siam Toyota Manufacturing in [[Chonburi (city)|Chonburi]], [[Thailand]] ([[#1NZ|1NZ-FE]] for [[Toyota Yaris|Yaris]] and [[Toyota Vios|Vios]]);<ref name="Asia plants">{{cite web |url=https://www.toyota-global.com/company/history_of_toyota/75years/data/automotive_business/production/production/overseas/overview/asia.html |title=Overview of Overseas Production Affiliates: Asia |archiveurl=https://web.archive.org/web/20121206012223/https://www.toyota-global.com/company/history_of_toyota/75years/data/automotive_business/production/production/overseas/overview/asia.html |archivedate=December 6, 2012 |publisher=[[Toyota Motor Corporation]] |url-status=live}}</ref><ref>{{cite web |url=http://www.siamtoyota.co.th/about.aspx#product |title=About STM |archiveurl=https://web.archive.org/web/20140219213006/http://www.siamtoyota.co.th/about.aspx#product |archivedate=February 19, 2014 |url-status=live |publisher=Siam Toyota Manufacturing}}</ref> and by [[Indus Motors Company|Indus Motor Company]] in [[Karachi]], [[Pakistan]] ([[#2NZ|2NZ-FE]] for [[Toyota Corolla|Corolla]]).<ref name="Asia plants" />

From the second half of 2003, the [[valve train]] mechanism of the [[Japanese domestic market|Japanese market]] 1NZ-FE engine was changed from a [[tappet|direct acting]] type to a indirect type with roller [[rocker arm]]s and [[Hydraulic tappet|hydraulic lash adjuster]] (HLA).<ref name="toyotaclub">{{cite web|url=https://toyota-club.net/files/faq/05-07-10_faq_nz_eng.htm|title=Toyota NZ series engines|website=toyota-club.net}}</ref><ref>{{cite web|url=https://www.youtube.com/watch?v=AMgyUmxljIs|title=Отличия двигателей 1NZ FE|language=Russian|date=16 May 2017|first=Andrey|last=Toskin|via=YouTube}}</ref> The post-2006 [[#Turbo|1NZ-FE Turbo]] and LPG-hybrid [[#1NZ-FXP|1NZ-FXP]] engines are also using this valve train mechanism.
