Nissan Motor Co. says it has developed a new turbocharging system that provides improved torque and engine
response at low speeds in city driving.Nissan says the new system will give a 2.5 - liter engine the same fuel efficiency as a 2.0 - liter engine and the same low - speed torque as a naturally aspirated 3.5 - liter engine.The new system will be introduced in new models for the Japanese market later this year.The system is based on what Nissan calls a «linear charge concept,» which allows boost pressure to rise gradually with acceleration, increasing on a linear level from low to high speeds.
