DAYTONA BEACH, Fla. – As it makes the switch from carburetion to fuel injection in 2012, NASCAR has announced that Bosch will be its exclusive oxygen sensor supplier beginning next year. As an exclusive NASCAR Performance partner, Bosch will supply special wide-band oxygen sensors, specific to NASCAR vehicles, which will provide essential data to the fuel injection engine management system.

 Beginning with the 2012 Daytona 500, all NASCAR Sprint Cup Series racecar engines will be fuel injected. An onboard computer will control the fuel injectors, using input from the oxygen sensors in the exhaust to determine the exact fuel provided to the airflow just as it is entering the cylinder. Several NASCAR teams have been testing fuel injected engines on-track to see how the new systems operate in actual racetrack conditions.
