  • Publication number: 20210324810
    Abstract: The present subject-matter provides a method to inject a non-combustible fluid, most preferably water, into an internal combustion engine, as well as a corresponding controller 12 and a computer program product for carrying out the method by means of a computer. It is a particular technical advantage of the claimed subject-matter that it allows for suppressing knocking in an internal combustion engine without any drawbacks regarding exhaust gas emissions. This advantage is achieved by avoiding collision of fuel and water spray when injecting both fluids directly into the cylinder 100.

  • Patent number: 10823104
    Abstract: The purpose of the present invention is to detect variations between the quantities of fuel injected into cylinders by fuel injection devices and correct the fuel injection quantity variation while minimizing the computational load on a drive device and the level of performance required of a pressure sensor. A drive device for fuel injection devices according to the present invention performs control wherein movable valves are driven so that predetermined quantities of fuel are injected by applying, for the duration of a set energization time, a current that will reach an energization current to solenoids of a plurality of fuel injection devices which open/close fuel flow paths. The drive device is characterized in that the set energization time or energization current is corrected on the basis of a pressure detection value from a pressure sensor that is attached to a fuel supply pipe disposed upstream of the plurality of fuel injection devices.
