Concepts and Technologies for Minimum Emissions and Maximum Efficiency
IAV is paving the way to zero-emission driving – with state-of-the-art exhaust gas aftertreatment and hybrid systems as well as all-electric drives. A modified topology for the exhaust gas aftertreatment system in conjunction with IAV’s new hybrid transmission is helping to cut emissions while enhancing driving dynamics. For all-electric vehicles, IAV has developed a modular electric drive unit that permits local zero-emission driving.
We presented all three solutions at the Vienna Engine Symposium on April 27 and 28.
Innovative Close-Coupled Exhaust Gas Aftertreatment
Diesel engines will only be capable of meeting the EU6 standard if exhaust gas aftertreatment (EAT) continues to be improved. To this end, IAV is moving the EAT system closer to the engine and positioning some or all of its components upstream of the turbocharger, leaving exhaust gas in DOC and SCRF between 100 and 150 degrees kelvin hotter than with the classic approach of positioning EAT downstream of the turbocharger. This shortens the time the exhaust gas aftertreatment system takes to reach optimum operating temperature – and the vehicle complies with emission requirements in all situations. (...) More
Optimized Efficiency of Hybrid Transmissions
Adding a modern hybrid transmission further reduces fuel consumption. IAV has developed a hybrid eight-speed dual-clutch transmission guaranteeing maximum combustion engine efficiency in all driving situations and across the operating map. Factoring in the benefit from hybridization and innovative hydraulic system produces a potential fuel saving of 18.1 percent over a conventional six-speed transmission. (…) More
Modular, electric drive concept
The new generation of electric drive units from IAV provides the key to an all-electric car. The modular concept comprises an electric motor and transmission with one to three gear speeds. This solution delivers a high level of torque over a wide speed range, while also taking up little package and permitting cost-efficient volume production. The modular electric drive unit provides high hill-climbing ability in conjunction with maximum efficiency. It can also be used flexibly and lends itself to a variety of powertrain configurations, e.g. for battery-powered electric or fuel cell vehicles. (…) More
