The Toyota NR engine family is a series of small inline-four piston engines designed and manufactured by Toyota, with capacities between {{convert|1197|and|1498|cc|L|1|order=flip}}.

Common features of this series

The NR series uses an aluminium engine block and cylinder head. The valve mechanism is equipped with 4-valves per cylinder, DOHC, and implemented Toyota's Dual VVT-i and VVT-iW. It also uses multi-point or direct fuel injection. The 1NR, 2NR, 3NR, 4NR, 5NR, 6NR, and 7NR engines have Dual VVT-i standard and the 8NR engine has VVT-iW, enabling it to operate in the Otto cycle as well as a modified-Atkinson cycle to improve thermal efficiency.

1NR-FE

The 1NR-FE is a compact 1.3-litre inline-four piston engine featuring Stop & Start technology and Dual VVT-i. It was introduced into the 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 optimize 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 {{convert|1297|cc|L|order=flip|abbr=on|1}} 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 {{NOx}} emissions.

Technical specifications of the engine:

  • Displacement: {{convert|1329|cc|L cuin|order=flip|abbr=on|1}}

1NR-VE

File:1NR-VE.jpg]]

The new 1NR-VE engine was improvised by Daihatsu for the Toyota Avanza and Daihatsu Xenia, and then later used by Perodua for the Perodua Bezza, which is based on the 1.3-litre 1NR-FE. It has ECE fuel consumption figures of {{convert|21.7|km/L|L/100km mpgus mpgimp|abbr=on|}} for the manual variant and {{convert|21|km/L|L/100km mpgus mpgimp|abbr=on|}} for the automatic. The engine produces {{convert|69-73|kW|hp|0|abbr=on}} and {{convert|121|Nm|0|abbr=on}} of torque.

The Perodua Bezza Advance variant and all variants of the new third generation Myvi are capable of {{convert|22|km/L|L/100km mpgus mpgimp|abbr=on|}}, courtesy of the new Eco Idle stop-start system and regenerative braking better than the previous generation engines.

1NR-FBE

Fitted to the Toyota Etios and Yaris hatchback made in Brazil, available only as a flexfuel, 1.3 litre, with VVT-i. Replaced by a flexfuel version of the 1NR-FKE in 2016.

1NR-FKE

The 1NR-FKE is a variant of the 1NR-FE introduced in the second quarter of 2014.{{cite press release |url=http://newsroom.toyota.co.jp/en/detail/1693527/ |title=Toyota Develops Engines with Improved Thermal, Fuel Efficiency |publisher=Toyota |location=Japan |date=2014-04-10 |access-date=2018-06-23}} Toyota claims it will have a maximum thermal efficiency of 38 per cent. This 1.3-litre petrol engine is employing the Atkinson cycle like hybrid-dedicated Toyota engines. The maximum torque is lower, 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 per cent.

Main differences between 1NR-FE :

  • Max. output: {{cvt|73|kW|PS bhp|0|}} at 6000 rpm
  • Max. torque: {{convert|121|Nm|lbft|abbr=on|0}} at 4400 rpm
  • Max. thermal efficiency : 38%
  • Expansion ratio: 13.5:1
  • Valve mechanism: VVT-iE
