Product Description
Functional Features
● Integral cylinder head and roller rocker arms: The integral cylinder head enhances the stiffness of the camshaft bearing bracket, ensuring more stable coordination among the valve-train components; at the same time, assembly accuracy is improved, reducing abnormal noises and vibrations, thereby delivering smoother and quieter engine operation. The use of roller-bearing rocker arms significantly reduces friction on the cam lobe contact surfaces, lowering mechanical losses and extending the service life of both the rocker arms and the camshaft.
● Secondary oil filtration: The secondary filtration system components further filter the oil after it has undergone primary filtration, thereby ensuring the engine’s durability and reliability.
● Advanced camshaft pressure-reducing valve technology—highly efficient and reliable. Featuring a brand-new camshaft pressure-reduction mechanism, this design delivers significantly improved pressure reduction, durability, and reliability. It makes starting easier and faster while effectively extending the service life of the starter motor and battery.
● Piston Spraying Technology: An innovative technological advancement that enhances efficiency. This new engine piston spraying cooling system uses a spray-based approach to cool both the piston and the piston pin, significantly improving the cooling performance of these critical components.
