fitur umum dari seri ini
seri nr menggunakan blok mesin dari aluminum dengan kepala silinder dohc. mesin ini juga menggunakan injeksi bahan bakar multi-point atau langsung, dan memiliki 4 katup per silinder.
mesin 1nr, 2nr, 3nr, 4nr, 5nr, 6nr, dan 7nr memiliki dual vvt-i standar dan mesin 8nr memiliki vvt-iw, memungkinkan untuk beroperasi di otto cycle serta atkinson cycle yang dimodifikasi, memaksimalkan efisiensi termal.
the 1nr-fe is a compact straight-4 piston engine featuring "stop &
start" technology and dual vvt-i.
it was introduced into european market in late 2008 with the yaris xp9f. improved engine performance combined with low emissions and fuel consumption was the principal aim during its development.
advanced engineering has been applied throughout the 1nr-fe engine.
toyota engineers streamlined the engine's intake channel, used computer simulation to optimise airflow, smoothened all surfaces for less turbulence and rounded off all angles and sharp edges inside the engine.
one of the key elements of the 1nr-fe engine is its piston design.
smaller and lighter than on the previous 1.3 unit, they are designed with a smaller contact area and use carbon ceramide, an advanced material commonly used in formula one engineering, to reduce friction.
the engine also features cooled exhaust gas recirculation (cold area specification models only) to reduce pumping losses and reduce

the 1nr-fke is a variant of the 1nr-fe introduced in quarter 2 of 2014.
toyota press presentation of news engines - 2014-04-10 toyota claims it will have a maximum thermal efficiency of 38 percent.
major feature, this 1.3-liter gasoline engine is employing the atkinson cycle like hybrid-dedicated toyota engines.
the maximum torque is lesser, but, this time, the maximum output is not reduced.
valves are driven with variable valve timing-intelligent electric vvt-ie.
the intake port has a new shape that generates a strong vertical tumble flow.
combustion is improved, and loss reduced.
toyota says that with idling stop and other functions, it will lead to fuel efficiency gains of approximately 15 percent.
main differences between 1nr-fe :
max. output: max. torque: max. thermal efficiency : 38%
expansion ratio: 13.5:1
valve mechanism: vvt-ie

a 1.5 (1496 cc) variant of the nr series engine.
first introduced in q4 of 2010 for the toyota etios.
it is the first new engine toyota developed for over 8 years without vvt-i.
done to reduce cost for the low-cost toyota etios.
a new innovation that made its introduction on this engine is the integration of the exhaust manifold into the cylinder head toyota etios launch site to reduce emissions.
a dual vvt-i equipped version was first used in toyota avanza.
