MARINE PROPULSION SYSTEMS
THE GREAT FUTURE OF SMALL ENGINES
ARENS MOTORS is a specialist for internal combustion engines that are smaller, lighter and less polluting than other engine technologies, with the same performance. The use of proven mechanical design concepts in conjunction with state of the art materials and injection technology enables a new class of ultra-compact drives. ARENS RVI boxer motors are characterized by maximum reliability, simple design and easy handling. ARENS MOTOR breaks away from the four-stroke paradigm. ARENS RVI boxer engines do not require camshaft, valve tappets, oil change, oil sump or separate forced induction systems. Whether as direct drives or range extenders ARENS RVI boxer engines can be installed in all configurations and in the narrowest engine compartments.

SYPROP
Next Generation Drive Systems
SYPROP – THE FIRST FULLY SYMBIOTIC MARINE PARALLEL HYBRID
A combustion engine operable like an e-drive, an e-drive with the range of a combustion engine. Drive silently and emission-free and experience power and endurance when it counts.
MARINE PROPULSION SYSTEM
RVI SAIL 15
READY-TO-INSTALL PROPULSION SYSTEM
ARENS RVI SAIL 15 // Most compact inboard engines on the market
The ARENS RVI SAIL 15 is suitable for small runabouts and sailing boats. The engine, foundation and Saildrive are designed as a complete system which, at 45 kg, is only half the weight of comparable systems and requires 40% less installation space. A real innovation is the plug-and-play principle, which allows the engine to be removed quickly and easily when maintenance is required.

Our Mission
The current environmental crisis requires new drive technologies that are characterized in particular by resource efficiency and minimal pollutant emissions. At the same time, the advantages of using known technologies should not be lost. These include, in particular, a high range and reliability as well as low costs. There is a growing awareness that the electrification of drives has a long way to go. Vehicles and mobile systems that have to be operated autonomously for long periods of time require a clever compromise between weight, installation space and low emissions. Neither electric nor established combustion engine drive technologies can meet this compromise in all fields of application.
In the field of small land, air and water vehicles, as well as of mobile generators, it is increasingly difficult to meet future requirements with established engine technologies. The almost exclusively used four-stroke technology makes downsizing of the engines to less than one litre of displacement difficult.
The limited power density of the four-stroke engines requires additional auxiliary units, which make the construction of the engines more complicated and thus more expensive. By contrast, the space and weight gains achieved are low. The long-range drive systems of the future will require innovative combustion engines that are significantly smaller, lighter and simpler. This is precisely ARENS MOTOR’s mission.Engine variants for different fuels and performance requirements can be derived from the ARENS RVI engine platform. ARENS RVI boxer engines are ideally suited for use as drive machines for small vehicles, plug-in hybrids or mobile generators. In addition to the attractive motor characteristics, ARENS RVI boxer motors meet the requirements for the digital future. ARENS RVI motors are equipped with electronic interfaces that enable networking via the Internet of Things (IoT).
