DLE 130 DLE130 LUTAN EFI 13HP Engine for Rc Fixed Wing

In the EFI system, the amount of fuel required by the engine is provided by the injector controlled by the ECU. The Electronic Control Unit (ECU) performs the calculations required to optimize the fuel supply and ignition timing based on the information provided by various sensors, including intake temperature sensors and cylinder temperature sensors, crankshaft position sensors, atmospheric pressure and manifold pressure sensors, and throttle position sensors. The EFI system can maintain the air-fuel ratio required for the good operation of the engine according to the working conditions and engine requirements.

Advantages of Electronic Fuel Injection (EFI):

Lower fuel consumption

EFI systems have lower fuel consumption than carburetor engines. This is due to a sophisticated electronic control system that continuously calculates and adjusts the air/fuel ratio to maintain ideal combustion conditions. Small carburetors tend to make the engine mixture too rich (oil-rich) at both low and high power outputs. Carburetors are particularly inefficient when used under continuously changing conditions because it is difficult to set the ideal air-fuel ratio for all throttle opening positions. Effective height compensation is difficult to achieve with carburetors, while with EFI, height compensation is built into the system and works seamlessly. Although the fuel consumption reduction will vary depending on the engine and various conditions, the fuel consumption will be reduced by 5% to 25% compared to a carburetor engine.

More power

Engines equipped with EFI systems typically provide higher power and torque than carburetors of the same engine. While it is difficult to optimize power and/or torque within the carburetor engine rpm range, EFI systems are able to optimize air-fuel ratio and ignition timing over the entire operating rpm range, while compensating for other factors to maintain continuous engine performance. Typically, an engine equipped with EFI produces 5% to 10% more power than a carburetor version of the same engine.

Higher reliability

An engine equipped with an EFI system is inherently more reliable than a carburetor engine. This is due to the fact that the EFI control system maintains an ideal air-fuel ratio during all phases of flight. Compared to a carburetor, an EFI system is less prone to freezing. The problems of random engine stops, spark plug oil immersion, and unsatisfactory air-fuel ratios are eliminated. Carburetors are prone to malfunctions. This requires constant adjustment, and there is a great risk of stopping during long periods of continuous operation due to drift in the settings. On the other hand, the EFI engine is always in the same tuned state. This not only increases reliability, but also reduces the amount of daily maintenance required.

Good startup

One of the main advantages 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 oil droplets produced by the fuel injection compared to the carburetor. The engine can be started in a variety of conditions, whether it is a hot summer or a cold winter, sea level areas or high altitudes, the engine can be easily started.

Full altitude compensation

The EFI system has a highly compensated system. Continuously monitoring the atmospheric ambient pressure, 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.). It is difficult to achieve height compensation with a carburetor engine, especially if it needs to be operated at different altitudes. This always requires a compromise carburetor needle adjustment, which means that at least part of the time the air/fuel mixture is not ideal, which can lead to excessive fuel consumption when the mixture is too thick, and may damage the engine when the mixture is too thin.

Aimed at the throttle body designed for the drone, the structure is compact, and the wiring harness of the integrated design, the ECU adopts the J30J aviation plug.

The ECU integrates atmospheric pressure sensors and negative pressure sensors, automatically adjusting the fuel injection volume in real time according to the flight altitude. In the actual test at an altitude of 5000 meters above sea level, all states are normal, and the full throttle speed of the engine is basically the same as that in the plain area (the static pull force is 60% in the plain area).

Adopting self-developed small-scale automatic pressure control oil pump, it only needs to be connected to YouTube and the fuel injector to exit YouTube, without returning to YouTube, easy installation and high reliability. The oil pump power consumption is only 3 watts (12V, 250ma).

The electric start version of the DLE60 EFI adds a set of reduction gears, the starting motor is a customized brushless motor, the installation part of the propeller is made of 7075 aviation aluminum, and the reduction gears are all nitriding.

The engine has been tested and basically run-in for two hours before leaving the factory, and can be directly installed and used without adjustment.
