A 1.8l direct injection petrol engine, matched to its latest continuously variable transmission has been launched by Nissan. The company claims the combination gives a 50% improvement in fuel economy and a 35% reduction on CO2 emissions over a conventional engine of the same capacity, while at the same time improving driving performance.
It is capable of recognising a driver’s acceleration as demand torque and responds by smoothly alternating between stratified and homogenous charge combustion. Stratified charge combustion creates an overall lean mixture consisting of a highly combustible mixture around the spark plug surrounded by a layer of air without fuel, while homogenous charge combustion is a method similar to a conventional gasoline engine in which mixture is uniformly mixed to a stoichiometric ratio and combusted.
Making its debut at the Birmingham Motor Show, Nissan’s Hypermini is designed for short trips around the city, the ultra-small, two-seater electric vehicle with a top sped of 62mph and an 80 mile range, occupies minimal parking space. Its safety features are equal to those of a conventional small car, while its ‘no contact’ electromagnetic battery charging system allows safe charging in all weather conditions.
In addition, the Hypermini only requires 25% of the energy of a conventional car.
