At the US Department of Energy’s (DOE’s) Annual Merit Review meeting in Washington, DC last week, Michael Ruth from Cummins noted that the DOE program target for the project is a fuel economy (CAFE) target of 26 mpg (9.05 Exhaust system configuration. Earlier post.). l/100 km) for a vehicle of that size.

A team at Monsanto and colleagues at AVL Powertrain have successfully designed and demonstrated an onboard low-temperature ethanol reformer that can be driven by exhaust heat. Many papers have described high-temperature steam reforming of ethanol at around 600 °C but.this temperature is too high to be driven by engine exhaust.

The VEMB system uses a concentric camshaft, blow-down manifold and scavenge manifold to separate the exhaust event into two phases: high-energy blow-down to the turbo without pumping losses, and high-hydrocarbon scavenge to the EGR system. to 2 ratio points and maintain the same knock limit for an additional 3-4% improvement in fuel economy.

Unlike exhaust-driven turbochargers, electric superchargers are driven by an electric motor. Highly efficient at low engine revolutions, electric superchargers make it possible to downsize engines. version of the vehicle but with fuel economy and CO 2 emissions approaching those of a Prius.
