To reduce friction, the rocker arms have built - in rollers.

• Two - lobe overhead cam and a pair of needle - roller rocker arms reduce friction by 50 percent for increased fuel efficiency and torque.

Measures to reduce friction losses and thus help enhance engine efficiency include the adoption of narrow, lightweight roller rocker arms and low - friction timing chains, while D - 4S direct fuel injection helps create optimum combustion conditions, contributing to enhanced fuel efficiency.

The NR engine family (there's also a 1.5 L version in the Avanza) comes with intake and exhaust Dual VVT - i, teflon coating for the pistons (to reduce friction and improve durability), larger water jackets (better cooling, improved combustion, lower noise), roller rocker arm (reduces friction between rocker arm and camshaft) and iridium spark plugs (the 1.0 L KR in the Bezza and Axia also uses the latter).
