What does 1.5 naturally aspirated mean?

[OPaislee]

1.5 naturally aspirated refers to an engine intake method where air is drawn into the combustion chamber by atmospheric pressure without forced induction. Here are some key engine maintenance considerations: 1. Use high-quality engine oil: Engine oil lubricates, cleans, cools, seals, and reduces friction in the engine. Only qualified lubricants can minimize engine component wear and extend service life, so always ensure you use premium lubricants. 2. Regularly clean the fuel system: Proper engine maintenance requires fuel system care. Periodic fuel system cleaning helps control carbon buildup, keeping the engine in optimal condition. 3. Regularly descale the radiator: Rust and scale buildup in the engine radiator are common issues. These deposits restrict coolant flow, reduce cooling efficiency, potentially causing engine overheating or damage. Therefore, always select coolant with appropriate concentration ratios for routine maintenance.
