DETERMINATION OF SPEED AND DYNAMIC CHARACTERISTICS OF A SPORTS MOTORCYCLE ENGINE WITH A SYSTEM FOR SWITCHING FROM A 4-STROKE TO A 2-STROKE CYCLE OF OPERATION
Abstract
The article examines a prototype sports motorcycle four-stroke gasoline engine capable of switching to a 2-stroke cycle at low and medium revs under full load. The engine must be equipped with a compressor in order to ensure the best purge in two-stroke mode. The engine improves speed characteristics, namely power and torque at low speeds, as well as the dynamic performance of the motorcycle itself (acceleration from 0 to 100 km/h). According to the calculation method, it was possible to determine that the power of the motorcycle will increase by 1.5 times at a low speed, and the acceleration will decrease by 0.62 sec. The data were obtained on the basis of calculation modules developed at The Moscow Automobile and Road Construction State Technical University (MADI). The consistency of the results was tested on a prototype 2/4-Sight engine.
