The group found that using the waste heat with optimal controls consistently delivered higher oil temperatures and significantly reduced warm-up times. This translated to fuel economy improvements of almost 4% compared to conventional thermal management strategies. The largest efficiency gains occur while heating oil from a cold start, and approximately half of the improvement comes from the powertrain and transmission sides.
"We first needed to understand how much heat was available from the powertrain during various drive cycles and cold start conditions," he says. By simulating thermal components that control the powertrain heat, such as the electronic thermostat, cooling fans, grill shutters, and water valve, they determined the best way to distribute the available energy.
