HR12DE Engine


Three-cylinder engine, lightweight, compact and good mileage

This three-cylinder engine is compact and lightweight, and easy to use in everyday life. It produces strong torque for medium and low speeds and also achieves excellent fuel efficiency. Further, it has the quietness equivalent to a four-cylinder engine, with only three-cylinders.

Technology Functionality

Improving fuel efficiency

One way to implement low fuel consumption is by reducing friction on movable parts. Nissan developed a three-cylinder engine with fewer parts than a four-cylinder engine. Reducing the number of parts reduces friction and as a result, achieves lower fuel consumption. At the same time, it improves combustion efficiency, achieving better mileage.

Reduction in vibration and sound

In general a three-cylinder engine tends to be louder and with more vibration than a four-cylinder engine. By employing an outer balancer to reduce vibration and noise, quietness was achieved equivalent to that of a four-cylinder engine.

Technology Configuration

Improving combustion efficiency

Occurrence of knocking was also curbed by the successful lengthy retention of tumble flow in the center of the combustion chamber by re-adjusting the combustion chamber shape and employing a deep piston. This led to the improvement of combustion efficiency and being able to curb fuel combustion.

Curbing vibration by an outer balancer

This mechanism adjusts the balance by placing weight on both sides of the crank shaft. As a result, the up-down oscillation of typical of a three-cylinder engine is reduced, achieving quietness equivalent to a four-cylinder engine.



e-POWER delivers a responsive drive with smooth acceleration like an EV.

Mild Hybrid

Mild Hybrid is a compact hybrid system that improves fuel efficiency by utilizing the energy during deceleration.


The CVT (Continuously Variable Transmission) provides smooth and "stepless" ratio changes, unlike conventional transmission systems that use sets of fixed gears.
