One part of improving the car infrastructure is the gradual shift toward digital technology. And by this we don’t just mean the entertainment and navigational systems that most cars carry today. This includes the analog parts that include improving the temperature control systems.

This includes addressing the critical fluid systems that will help improve the life of fluids of various engine components. With the Digital Rotary Control Valve, this can be done. The Digital Rotary Control Valve (DRCV) will provide a “true” powertrain thermal management system that, after mapping, will always allow the engine/transmission to function at their “known” optimum operating temperatures, under all driving conditions. This is sort of like implanting in the engine to have a mind of its own.

“When you think of the sophisticated systems in a vehicle today, it comes as a surprise that we still use analog systems to control the interaction of the engine with the radiator system,” said Hollis, director of Advanced Research — MileageMatrix, Inc. “After all, those fluids protect the vehicle’s most important operating systems – the engine and driveline – and running them too high or too low simply wastes energy.”

Motorists who are curious about the level of their carbon footprints can simply look at one part of their car, their O2 censor. It’s important to know that your vehicle’s O2 sensor (oxygen sensor) plays a key role in sounding the alarm if excessive harmful exhaust emissions are coming out the tailpipe.

“A properly functioning O2 sensor plays the role of a watchdog when it comes to monitoring your car’s exhaust emissions, especially hydrocarbons and carbon monoxide,” said Warren Suter, Director, Engine Management Systems for Bosch, which developed the automotive oxygen sensor in 1976. Bosch is the world’s largest supplier of automotive parts and systems.

The O2 sensor measures the oxygen in the exhaust and signals the engine’s computer to adjust the air-fuel ratio to ensure that combustion is as complete as possible. This continuous process optimizes engine performance and fuel efficiency and reduces harmful emissions. A vehicle, depending on the make, model and year, can have between one and four O2 sensors at various locations in the exhaust stream.

If an O2 sensor is worn out and fails to assess the air-fuel ratio accurately, the engine’s computer tries to accommodate the perceived variation and, in the process, may adjust the mixture to be too lean or too rich. The result? Harmful tailpipe emissions and possible damage to the catalytic converter and other engine components.
