Our engine parts

Engine connecting rod
The mechanical strength belongs to the density of ADC12 aluminum alloy cast aluminum, and the weight monitoring can ensure the consistency of structural tensile strength and processing CPK

Engine piston
Adopt Z109 material to increase the wear resistance and reduce thermal deformation, to ensure the weight of the piston and the accuracy of machining

Engine case
Using high-precision fixtures, machining center equipment to ensure precision, and high-density material strength, BISON's box can meet the durability test for 125 hours, and can meet emission standards

Intake and exhaust valves
The valve is made of 40Cr10SiMo material. The exhaust valve can withstand high combustion temperature. When the load is heavy or the combustion condition is abnormal, the temperature limit will not be affected if the temperature limit is lower than 700-780°C.
Engine testing

Dedicated to engine testing, and equipped with quality control for sampling testing. BISON verifies and confirms the performance and reliability of each batch of engines to avoid possible product failures.
Guarantee the sealing performance of the crankcase body structure and installation. Through professional instrument testing, poor sealing defects of installation and materials can be found, so as to avoid oil leakage and oil leakage of the engine and ensure the actual power efficiency.
The load output stability of the power can be confirmed online, and the configuration can be locked after stabilization to ensure high product consistency
