Automotive Type Electronic Fuel Injection System
EnergyStorm EFI computer-controlled fuel and ignition system
This generator has a computer-controlled fuel and ignition system. An on-board computer, referred to in this
manual as an ECU (
Engine Control Unit
) utilizes a series of virtual maps (
lookup tables
) that provide values for
various aspects
of engine performance. The ECU analyzes data provided through the various engine sensors to
determine the best combination of values from these lookup tables to provide optimum performance. This is
communicated to the generator components through the use of digital signals. This is in contrast to non-
computer-controlled ignition systems that rely on mechanical feedback, and sometimes vacuum, to control the
motion of the various components.
The Electronic Fuel Injection (EFI) system provides increased efficiency over carbureted fuel systems. In a
carbureted fuel system, the fuel and air are mixed in a carburetor that relies on a mechanical choke system
controlling the rate of air intake to maintain the vacuum necessary to mix the fuel with air for combustion.
In a fuel injection system, the ECU calculates and adjusts the fuel mixture directly, based on real-time feedback,
allowing for greater fuel and emissions efficiency. The ECU also controls the timing for the spark plug,
dynamically controlling the speed of the engine depending on requirements for power generation.
When there is a problem reported by a generator component (such as an engine sensor), the ECU stores a fault
code for it. These fault codes can be read in the
Wattage (P)
field of the digital display, and then used to identify
the issue and correct it. For more information on fault codes and how to access them, refer to the
Fault codes
section of this manual. For more information on the digital display and its use, refer to the
section
of this manual.
