Development of CVT for 2008 Model Year FIT

Article of Honda R&D Technical Review Vol.20 No.2

Summary

A newly developed 1.3 L, 1.5 L class CVT with a torque converter was mounted in the second generation FIT, which is aimed at realizing both higher fuel economy and exhilarating acceleration performance. The main technologies used in the new CVT are the changeover of the start-off method from the conventional start-off clutch to a torque converter, the increase of the pulley distance from 143 mm to 156 mm, the adoption of a high gear ratio, and the adoption of an oil pump driven with a small radius rotor via a chain, a creep control system, and a start-off lockup clutch (L/C) control system.
As a result of these technologies, the transmission efficiency was 1.7% higher than that of the previous FIT CVT, and the torque amplification effect of the torque converter during launch enabled the achievement of higher fuel economy and exhilarating acceleration performance.
