In an EFI system, the amount of fuel required by the engine is supplied through injectors controlled by the ECU. The Electronic Control Unit (ECU) performs the calculations required to optimize fuel supply and ignition timing based on information provided by various sensors, including intake and cylinder temperature sensors, crankshaft position sensors, atmospheric and manifold pressure sensors, and throttle position sensors, and the EFI system maintains the air-fuel ratio required for good engine operation based on operating conditions and engine requirements.
Benefits of Electronic Fuel Injection (EFI).
Lower fuel consumption
EFI systems have lower fuel consumption than carbureted engines. This is due to a sophisticated electronic control system that constantly calculates and adjusts the air/fuel ratio to maintain ideal combustion conditions. Small carburetors tend to over-rich (fuel rich) the engine mixture at both low and high power outputs. Carburetors are particularly inefficient when used under continuously varying conditions because it is difficult to set the ideal air/fuel ratio for all throttle opening positions. Effective altitude compensation is difficult to achieve with carburetors, whereas with EFI, altitude compensation is built into the system and works seamlessly. While fuel consumption reduction will vary depending on the engine and various conditions, fuel consumption will be reduced by 5% to 25% compared to carbureted engines.
More Power
Engines equipped with EFI systems typically deliver higher power and torque than carbureted engines of the same engine. While it is difficult to optimize power and/or torque over the speed range of a carbureted engine, EFI systems are able to optimize air-fuel ratio and ignition timing over the entire operating speed range, while compensating for other factors to maintain continuous engine performance. Typically, engines equipped with EFI produce 5% to 10% more power than carbureted versions of the same engine.
Higher reliability
Engines equipped with EFI are inherently more reliable than carbureted engines. This is due to the EFI control system's ability to maintain the ideal air-fuel ratio during all phases of flight. EFI systems are less prone to icing than carburetors. Problems with random engine stops, oil-soaked spark plugs, and suboptimal air-fuel ratios are eliminated. Carburetors are prone to failure. This requires constant adjustment and a large risk of stopping during long periods of continuous operation due to drift in the setup. On the other hand, EFI engines always remain in the same tuning. This not only increases reliability, but also reduces the amount of routine maintenance required.
Good startability
A major advantage of the EFI system is the greatly improved cold and hot start performance. This is due to the system's ability to calculate the ideal air/fuel mixture and the better atomization of the fuel droplets produced by fuel injection compared to carburetors. The engine can be started in a wide variety of conditions, whether it is hot in the summer or cold in the winter, at sea level or at high altitude.
Full altitude compensation
The EFI system has an altitude compensated system. The ambient atmospheric pressure is continuously monitored and the ECU continuously calculates the ideal air/fuel ratio for that altitude, while optimizing the air/fuel ratio for other variables (temperature, throttle position, etc.). Altitude compensation is difficult to achieve with carbureted engines, especially if they need to run at different altitudes. This always requires a compromise carburetor fuel needle adjustment, which means that at least some of the time the air/fuel mixture is not ideal, leading to excessive fuel consumption when the mixture is too rich and possible engine damage when the mixture is too lean.
The throttle body designed for UAVs has a compact, integrated design wiring harness and the ECU uses J30J aviation plugs.
ECU internal integrated atmospheric pressure sensor and negative pressure sensor, according to the flight altitude automatically adjust the fuel injection amount in real time. In the actual test at 5000m altitude ground height, all states are normal, the engine full throttle speed is basically the same as the plain area (static tension is 60% of the plain area)
Adopt self-developed small automatic pressure control oil pump, only need to connect the oil inlet pipe and oil nozzle outlet pipe, no oil return pipe, easy installation and high reliability. The power consumption of the oil pump is only 3 watts (12V,250ma).
The electric start version of the DLE60 EFI has an additional set of reduction gears, the starter motor is a custom brushless motor, the propeller mounting part is made of 7075 aircraft aluminum, and the reduction gears are treated with nitriding process.
The engine has been tested and broken in for two hours before leaving the factory, so it can be installed and used directly without any adjustment.
