Technical features of the Avadi MA-250
The Avadi MA-250 is a four-stroke engine that works without conventional valves. Instead, it uses an old principle of the rotary valve in a modern way. Inside the engine, an oscillating piston moves in a cylinder. Unlike traditional engines, however, there is no classic crankshaft. Instead, the piston is connected to a fixed ring gear via two connecting rods, which converts the reciprocating motion directly into a rotary motion.
The connecting rods are offset at an angle of 180 degrees and connected to the ring gear via a pinion gear. This enables regular ignition every 360 degrees and ensures that the engine functions run smoothly. The cylinder itself also rotates and uses a control disk with ceramic seals to control the gas exchange.
Performance data and efficiency
The prototype of the Avadi MA-250 has a displacement of 250 cubic centimeters and produces 15 hp (15.8 hp, 11 kW) at 3,700 revolutions per minute. The maximum torque is 30 Newton meters (22.3 lb-ft) at 3,500 rpm. With a weight of only 11 kilograms (23 lbs), this engine is extremely light and compact. By comparison, a conventional Honda GX240 engine delivers 8 hp (6 kW) at 3,600 rpm and 17 Nm (12 lb-ft) at 2,500 rpm, but weighs 35 kilograms (77.2 lbs).
Advantages of the design
The Avadi MA-250 offers several decisive advantages:
- High efficiency: with an efficiency of 42 percent, the engine is on a par with modern diesel engines. Conventional motorcycle engines usually only achieve 30 to 35 percent.
- Low friction: The special design of the piston and cylinder, which rotate slightly offset to each other, minimizes friction. This reduces wear and increases efficiency.
- Easier cooling: The engine does not require water cooling or an oil pump, as lubrication is mainly provided by centrifugal force. This reduces the number of moving parts and therefore potential friction losses.
Potential applications
Due to its compact design and efficiency, the Avadi MA-250 is particularly suitable for applications that require continuous performance at low speeds. These include:
- Lightweight motorcycles and scooters: especially in urban environments, these vehicles could benefit from the low weight and high efficiency.
- Delivery vehicles and range extenders: The motor could be used in light commercial vehicles or as an auxiliary drive in electric vehicles.
- Power and cooling units: Stationary applications such as generators or cooling units could also benefit from the new technology.
- Light aircraft: The combination of low weight and high efficiency also makes the Avadi MA-250 interesting for use in aviation.
Outlook and further development
Although the Avadi MA-250 is currently still in the prototype phase, the test results to date show promising approaches. According to CEO Landon Wilkinson, the compression results are positive and further tests are imminent. If these tests are successful, the Avadi MA-250 could play a significant role in the further development of combustion engines.
As the world increasingly turns to electric mobility, the Avadi MA-250 offers an innovative alternative that combines the advantages of traditional and modern engine technologies. It remains to be seen how this technology proves itself in practice and what new possibilities it opens up for the future of mobility.
