Authors Abstract
Content
A concept for a new engine drivetrain control system that can attain improved exhaust emissions and fuel economy was investigated. The system integrates direct-injection stratified engines with high-pressure charge, a sophisticated continuously variable transmission, and hybrid systems such as electric motor drives. The system is composed of two three-cylinder engines, which are used singly or in combination according to the circumstances. During a traffic jam, the vehicle is driven by the electric motor, at partial load, it is driven by three cylinders, and at full load, by six cylinders with brake energy stored in a battery. The battery is charged at partial and full loads. The system has an expert subsystem that controls the charge and discharge of the battery according to driving data from a car navigation system. Some simulation results of fuel economy gain and exhaust emissions were evaluated using optimum control strategies.
