  • Device for modifying the amount of fuel combusted for an electronically fuel injected combustion engine
    Patent number: 11047330
    Abstract: A device that enables gasoline internal combustion engines to efficiently use fuel with higher ethanol content. The device measures various data such as ethanol content, RPM, temperature, intake air pressure, mass airflow, exhaust gas, crank sensor, among other data, to determine to an ideal enrichment pulse duration to apply to the fuel injector.
    Type: Grant
    Filed: November 26, 2019
    Date of Patent: June 29, 2021
    Assignee: StepOne Tech Ltd
    Inventors: Risto Harkonen, Miika Holtta, Tuomo Isokivijarvi, Pekka Salo
