Replacing an engine's thermostat with Schaeffler Group's powertrain thermal management module can reduce cabin warm-up time as much as 40% and boost fuel economy as much as 4%, according to the company.
The module, which is made of fiber-reinforced polyphenylene sulfide plastic, uses sensors and internal rotary slide valves to control engine and transmission temperatures. Schaeffler says the system can immediately provide sufficient engine cooling for hard acceleration yet maintain coolant temperature within 2 C.
The module can be adapted to specific powertrains simply by customizing its sensor output signals, according to Schaeffler. Audi is already using the device in its EA888 series four-cylinder engines in Europe.
