Summary
 Preliminary teardown of Nissan Note (Versa Note) performed on August 22, 2014 * Click on the photo for a larger image. |
The Nissan Note teardown was conducted in August 2014 by the Automotive Technology Innovation Center of the Hiroshima Industrial Promotion Organization. The teardown of the major safety technologies, such as the Around View Monitor with Moving Object Detection (MOD) function and emergency braking, and the advanced driver assistance systems is reported in Nissan Note (Versa Note) Teardown (Part 1).
This report (Part 2) describes teardown of the supercharger, engine, and the Xtronic CVT with auxiliary gearbox. It focuses specifically on the air flow to the engine, the supercharger drive method, and engine components. In addition to the photos taken at the teardown event venue, the report will make use of the photo of the cutaway model of the CVT displayed by Jatco at the Automotive Engineering Exposition 2014 held in May.

| Engine | 1.2-liter (1,198cc) inline 3-cylinder direct-injection supercharged gasoline engine (72kW/98ps maximum output, 142Nm/14.5kgf-m maximum torque) manufactured by Aichi Machine Industry, Type HR12DDR | |
|---|---|---|
| Supercharger | Four-lobed Roots type supercharger manufactured by Eaton. * The 1.2-liter 3-cylinder engine has smaller displacement than the 1.5-liter 4-cylinder engine that is used in the previous Nissan Note. This leads to higher fuel efficiency and lower travelling performance. The supercharger is used to make up for the poorer driving performance. * When compared to the turbocharger, the supercharger responds faster to the accelerator pedal operation and can be engaged and disengaged by a clutch. |

| CVT | Xtronic CVT with auxiliary gearbox manufactured by Jatco. | |
(Note) A supercharger takes power from the engine's crankshaft to drive its compressor. A turbocharger takes off power from the engine's exhaust gas to drive the turbine connected to the compressor.
