Nissan announces fuel-saving technologies for FY2010
The company says its zero-emission vision is based on two key pillars, ZERO EMISSION and PURE DRIVE, which provides consumers a comprehensive range of eco-technologies from which to choose. While ZERO EMISSION is the ultimate goal, the company is committed to ongoing innovation in technologies that increase efficiency and reduce emissions. As a result, Nissan offers a range of automotive technologies, including CVT, Idling Stop, HEV and Clean Diesel.
In Japan, the first PURE DRIVE vehicle, the New March, will be launched this month equipped with idling stop technology achieving a class leading 26km/l fuel economy, followed by the Clean Diesel X-TRAIL with automatic transmission and the Fuga Hybrid (Infiniti M hybrid in US and Europe) luxury sedan.
The new technologies comprise:
Newly Developed Nissan March Compact Car Powertrain
The Nissan March uses a newly developed compact car powertrain, which is anchored by a new three-cylinder engine and next-generation XTRONIC CVT (Continuously Variable Transmission).
Developed in pursuit of lighter weight and a smaller size than previous engines in the compact car class, the new three-cylinder 1.2-litre HR12DE engine requires fewer moving parts compared to the more commonly used four-cylinder engines.
There's also a new XTRONIC CVT, which is smaller and lighter than previous CVT designs, whilst also achieving a 30% friction reduction for powerful acceleration performance, quiet operation and improved fuel economy.
A new Idling Stop system has also been adopted which, says Nissan, can be restarted on a sloping road without sliding backwards. The engine restart time has also been shortened.
Clean Diesel X-TRAIL with Automatic Transmission
The automatic transmission X-TRAIL equipped with a clean diesel engine (M9R) will 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.
Along with the use of highly precise consolidated engine control, the AT Clean Diesel X-TRAIL utilises a new "highly dispersive lean NOx trap (LNT) catalyst", which enables the use of a clean diesel engine compatible with the post-new long-term regulations in automatic transmission equipped cars.
High-Efficiency Hybrid System
Nissan has developed a new hybrid system, targeted to be the most efficient one-motor, two-clutch parallel full hybrid system. It utilises an electronically controlled clutch positioned between the engine, motor and drive wheels.
It is said to be highly energy-efficient because the battery is charged efficiently by the engine while driving, while the rotational energy of the wheels is used for energy regeneration. The motor is powered by a laminated lithium-ion battery featuring the same structure as the one used on LEAF, Nissan's electric vehicle.
The hybrid system is scheduled to be available on the Infiniti M in late 2010.
The World's First Mass-Produced 1.5-litre Engine with Dual Injectors
Another advanced fuel-efficient technology to be launched in FY2010 is Nissan's new 1.5-litre engine (HR15DE), said to be the world's first mass-produced 1.5-litre engine with dual injectors. This unit offers an improvement in fuel economy of approximately 4% compared to Nissan's conventional engines in the same class. The engine is mounted on the Nissan JUKE, which was launched in Japan in June 2010.
A Newly Developed 1.6-litre Direct Injection Gasoline Turbocharged Engine
Based on the downsizing concept, a new 1.6-litre 4-cylinder MR16DDT engine with Direct Injection Gasoline technology has been developed – combining a turbocharger with a low displacement engine to achieve both higher power output and lower fuel consumption.
The MR16DDT engine achieves power equivalent to that of a 2.5-litre engine, along with the fuel efficiency equivalent to a 1.8-litre engine. The new engine will be available in the Nissan JUKE in the second half of FY2010.
Commenting on the latest developments, Takao Katagiri, SVP for marketing & sales in Japan, said: 'The adoption of different types of low-emission technologies is a great solution as we can attend different consumer needs. PURE DRIVE vehicles will offer customers a wider selection of models fitting both their financial and environmental needs.'
