Due to the fact that the main engines sold on the market are two-stroke engines, which lack simulation and sound unpleasant, I began to pay attention to four stroke multi cylinder internal combustion engines. However, there was no high-performance internal combustion engine on the market that I wanted. Therefore, I began to try making four stroke multi cylinder internal combustion engines myself and created the "RUIFEIYA" brand. I started making inline twin cylinder four stroke engines "NR-200" and inline four cylinder four stroke engines "L4-172", which received high praise. After accumulating certain experience, I began to develop and research pure gasoline multi cylinder high simulation internal combustion engines.
