We have an exciting video to share with you! I’m delighted to share this video because it reminds me of the work we used to do with Quaternium a few years back, showing off the capabilities of hybrid drones. In this case,there is a 77-mile flight made by the company Valmont Industries, Inc. with a …
The electronic fuel injection or EFI is an electronic system that manages the fuel injection autonomously in a dynamic way, compared to the manual setting of the carburetor. The EFI injects fuel directly into the throttle body. The amount of fuel required is calculated using a series of electronic sensors as input. What are the …
It is an interesting project of a very powerful, reed valve engine. It uses as base engine the robust and reliable Zenoah 32cc engine with a completely new billet machined crankcase and a new crankshaft with longer stroke. The Zenoah 32cc is an engine with which we have a lot of experience, it is an …

Honda GX25 and GX35 are 4-stroke, overhead cam single cylinder engines designed for garden equipment, agricultural equipment, water pumps… however they can also be used as powerplants for fixed wing and VTOLs drones and it have benefits over commonly used RC engines. They burn pure gasoline, without oil. Better fuel consumption. Reliable. The fundamental difference …
Small two-stroke engines usually come with Walbro carburetors, Löweheiser injection bodies have the same pattern as walbro carburetors to be bolt on. Not all walbro carburetors have the same bolt pattern, small series have 31 mm bolt spacing and larger WG and WB series have 46 mm. The carburetor size is not constant throughout the …

The origin of the heavy fuel engines is the military logistical need of “a single fuel on the battlefield”. This concept benefits both logistics and security. Today the technical conditions allow their application on small UAV engines. The idea here is to use a single fuel for all types of vehicles, both ground and air. …

BSFC is a measure that is used to express the consumption of the engine regardless of the size of the engine, so that the data can be used to compare the consumption of engines of different powers. In the international system, the BSFC is expressed as the mass fuel consumption (gr.) divided by the mechanical …

The following table shows a list of engines from popular RC manufacturers that can be converted to EFI engine systems to use as power plants for UAVs. Löweheiser throttle bodies have the bolt pattern of Walbro carburetors, and therefore installation on an engine that originally came with Walbro carburetors is straightforward without requiring any engine …

Last week, we announced a new partnership with the pioneer UAV manufacturer Quaternium, which led to the achievement of a new world record of multirotor endurance with an outstanding flight of 10h and 14 min with their drone. After years of research we developed a state-of-the-art fuel injection system and, combined with a world-leading drone like …
