Continental has introduced the Active Purge Pump (APP) as a new solution to meet stricter hydrocarbon evaporation legislation around the globe. Gasoline fuel is not only highly combustible, it also evaporates easily. The fumes - which contain benzene - pose a health hazard when inhaled and in combination with sunlight and exhaust gases they can cause photochemical smog which is a concern in large cities. This is why modern gasoline cars have a system onboard to minimise hydrocarbon emissions.
