We are a team dedicated to the hobby of internal combustion engines, and the R&D personnel in the team are all engine enthusiasts. By reading a large amount of engine information and referring to relevant literature, we are familiar with the advantages and disadvantages of some engines, and develop our engines based on the optimal performance and most reliable combination.
   At the same time, we also process some core parts ourselves (such as crankshafts, cylinder blocks, piston rings, cylinder liners, etc.), while some non core parts are processed through our partners.
   After all the spare parts are processed, we begin to measure the accuracy and size of the parts, select the parts that meet the accuracy requirements, and assemble them uniformly. During assembly, we use tools such as torque wrenches to ensure the precision of engine assembly (we have uploaded a video of the assembly process).
  Our team also supports various engine customization and mass production for engine enthusiasts.
