Tokyo, Aug 31, 2004 - (JCN Newswire) - Nissan Motor Co., Ltd. (TSE: 7201) today announced the development of two new 4-cylinder gasoline engines and a new continuously variable transmission (CVT). The new hardware units will be successively adopted on various small passenger cars, beginning with a new model scheduled for release in Japan this autumn.
(1) New 4-cylinder gasoline engines
The two newly developed engines, the 1.5-liter HR15DE and the 2.0-liter MR20DE, are both in-line 4-cylinder units, jointly developed by Nissan and Renault for use in both companies' passenger cars.
Application of the HR15DE engine will begin with Nissan's all-new Tiida model which will go on sale in Japan this autumn, while the MR20DE engine will first be applied to a new minivan scheduled for release later this year. Both engines incorporate a host of new shared technologies and are designed to provide excellent fuel economy combined with improved acceleration under the conditions most commonly encountered in everyday driving.
Specifically, the adoption of the following new technologies has substantially improved fuel economy and torque under ordinary driving conditions.
--The combustion period has been shortened and thermal efficiency improved by strengthening the gas flow in the combustion chamber.
--Some of the world's most advanced technologies have been employed to reduce friction, including the use of a new machining method for the cylinder bores and the application of a mirror-like finish to the crankshaft and cam bearing surfaces.
--The load imposed on the engine to drive the air conditioner and other auxiliary units has been reduced by enhancing their efficiency and improving the control program.
(2) New XTRONIC CVT
The newly developed CVT further enhances the benefits that characterize this type of transmission, including excellent fuel economy, smooth power delivery without any shift shock and outstanding acceleration performance. In particular, shift response has been improved by tuning the hydraulic and electronic controls. The shift response improvement combined with a wider gear ratio range contributes significantly to the acceleration and fuel economy under ordinary driving conditions.
