• Response speed improvement: The improved cylinder block and piston alignment accuracy reduce engine lag, making the throttle response more rapid, and allowing the driver to control the power output.
• Ensuring the product can operate stably for a long time under high temperatures, high pressures, and heavy loads.
• The key parts of the cylinder block are reinforced to increase its compressive strength and fatigue resistance, capable of withstanding greater engine power and torque output.
• It can effectively reduce friction between the piston and the cylinder wall, while improving the piston's high-temperature resistance, preventing the piston from deforming or damaging in high temperatures.
• Lightweight design: While ensuring performance and strength, through optimized structural design and the use of lightweight materials, the weight of the cylinder block and piston is reduced, lowering the vehicle's center of gravity, and enhancing handling performance.
