Aside from its electric LEAF, Nissan has been relatively slow to ‘green’ its cars, but that’s about to change.
Nissan has announced a range of advanced, fuel-saving technologies that will be introduced on new models to be launched in 2010, including a hybrid system.
The company says that the technologies are the culmination of its research and development efforts based on the Nissan Green Program 2010 (NGP 2010) – Nissan’s mid-term environmental action plan that includes initiatives to reduce carbon dioxide emissions in various fields within the scope of corporate activities.
Nissan will launch hybrid technology on its luxury Infiniti brand, with its M hybrid.
The company will launch the new Nissan March in Japan, with a new 3-cylinder engine and next-generation XTRONIC CVT. The engine is smaller and lighter and has fewer moving parts compared to the more commonly used 4-cylinder engines, with a reduction in friction of 20%.
The new XTRONIC CVT is 10% smaller and 13% lighter than previous CVT designs, while also achieving a 30% friction reduction. A new Idling Stop system has also been adopted.
The automatic transmission X-TRAIL equipped with a clean diesel engine (M9R) will also be launched this month in Japan. The vehicle will be compliant with the country’s post-new long-term regulations, the most stringent emission standards in the world.
Nissan has also developed a unique hybrid system, targeted to be the most efficient 1-motor, 2-clutch parallel full hybrid system. It utilises an electronically controlled clutch positioned between the engine, motor and drive wheels. The hybrid system allows for the elimination of friction by completely disconnecting the engine from the system during motor driving or deceleration. During test demonstrations conducted in city conditions, it was found that the engine was in a halt condition for almost 50% of the driving time.
The motor is powered by a laminated lithium-ion battery featuring the same structure as the one used on the LEAF, Nissan’s electric vehicle. The hybrid system is scheduled to be available on the Infiniti M in late 2010.
The forthcoming Nissan Juke will feature the world’s first mass-produced 1.5-litre engine with dual injectors. The fuel economy has been improved by approximately 4% compared to Nissan’s conventional engines in the same class.
The Juke will also be available with a new ‘downsized’ 1.6-litre 4-cylinder engine with Direct Injection Gasoline technology – combining a turbocharger with a low displacement engine to achieve both higher power output and lower fuel consumption.
Nissan claims that the engine achieves power equivalent to that of a 2.5-litre engine, along with the fuel efficiency equivalent to a 1.8-litre engine.
