Automakers are working on the research and development of engines to allow vehicles to run as far and as strongly as possible with less fuel. This involves an engine's combustion efficiency, or how efficiently fuel can be converted into power for a car to run.
In a car, gasoline explodes inside cylinders, and the force of this explosion is conveyed to the wheels, making the car move. However, if combustion is incomplete, gasses like CO (carbon monoxide) and HC (hydrocarbon) will be emitted. In other words, having less CO or HC in a car's exhaust gas means better combustion efficiency, which results in better mileage and more power. Therefore, it is possible to tell how efficiently a car's engine is working by measuring the amount of CO and HC in the car's exhaust gas.
Take the F1, the world's greatest racecar. Each F1 team makes a desperate effort to develop technologies that enable the cars to run faster. HORIBA's car exhaust emission measuring devices are used as essential mechanisms for such strict engine development, where even the slightest energy inefficiency is prohibited.
In this way, HORIBA's car exhaust emission measuring devices assist automakers all over the world, for their research and development of powerful engines with great fuel efficiency.
