🔧 Technical Insights
The piston moves inside the engine cylinder, creating the necessary compression for combustion. Because it is forged from high-strength alloy, it handles the intense heat and force generated during the combustion process. Moreover, the piston rings form a tight seal between the piston and cylinder wall, which helps maintain engine power and lowers emissions. Together, these features improve fuel efficiency and engine durability. Additionally, the design balances strength and weight, allowing the engine to run more smoothly and reduce vibration.
