The Aixro XR-50 continues to be a revolution in the karting world. There has never been such a combination of performance, drivability and reliability in this sport before. Here's why:
The XR-50 is a 4-stroke rotary engine working on the Wankel principle and consequently has no oscillating masses due to an eccentric shaft and rotor turning at 1/3 shaft speed. During each full rotation of the shaft one of three chambers is ignited. As all the moving mass is balanced, this type of engine layout is free from vibration, extremely powerful, compact in size and produces low emissions.
The XR-50 is a carburetor engine with mixture lubrication at a ratio of 50:1, but unlike in 2-stroke engines all oil is combusted without residue. Fresh gases initially flow through one end plate, stream through the rotor, bearings and shaft cooling and lubricating, before passing into the combustion chamber through the opposite end plate. At ~5500 rpm a negative-pressure controlled butterfly valve opens a second port feeding additional gases directly into the combustion chamber. These cold gases give rise to the enormous power of the XR 50. The untypical processes in the engine result in very long control times that positively influences exhaust gas values, which are typically under 1% of comparable 2-stroke units and equal to the best 4-stroke levels.
Powerful, lightweight and efficent. The XR-50 rotary engine combines all three of these qualties to make for the ultimate powerplant for the ultimate karting experience.
