Denso is an example of world-class engineering and are true innovators in electronic fuel injection technology. Denso introduced the 12-hole fuel injector design in 1999. This breakthrough design reduced fuel droplet size to 65 microns which provided superior atomization for improved engine efficiency. This was followed in 2002 with the UC injector which reduced droplet size down to 50 microns, about one-half the width of a human hair
Denso fuel injector is not just another injector but rather a precision instrument and features like welded seals allow DENSO fuel injectors to meet the most rigorous emissions requirements in the world, including those for Super Ultra Low Emissions Vehicles (SULEV) and Partial Zero Emissions Vehicles (PZEV).
