Sujit Jain, Regional President, Gasoline Systems North America, Robert Bosch LLC, talked to Lou Ann Hammond, CEO, www.drivingthenation.com, about the internal combustion engine using gasoline and how long it will be around. The new CAFE regulations and requirements are going to play havoc for the auto makers to get an average 54.5 miles per gallon from a gasoline engine, but Bosch is working on it. It is called Axle split hybrid topology. The technology uses a gasoline internal combustion engine.
Bosch says that they are able to use the existing engine, transmission & drivetrain. An electric motor on the rear axle allows zero emission driving. The axle split architecture hybrid benefits include improved drivability and eAWD, and improved fuel economy by using the efficiency of the internal combustion engine over its optimum operating range.
Jain says this technology could give the gasoline internal combustion engine 30 percent better fuel efficiency. Bosch sees gasoline direct injection (GDI) continuing to grow in the future, as it is a link needed to increase the fuel efficiency of gasoline internal combustion engines. Jain forecasts that by 2020, GDI will be on 50 percent of the light duty vehicles in North America. Hybrids and electric vehicles will make up 25 percent of all propulsion systems. The port fuel injection (PFI) is quickly being converted into higher technology systems.
Jains uses the Ford Escape as an example of what GDI and turbocharging can do and why it will be so popular.
