Reasons for high engine temperature at idle include installation issues, maintenance problems, and certain component failures. Below are the relevant explanations regarding high engine temperature at idle: Installation Issues: High temperature caused by installation issues. If the radiator is too far from the engine or the fan is outside the air duct, adjusting the radiator's installation position can resolve the issue. Maintenance Problems: High temperature caused by maintenance problems. Due to the engine's compact structure and narrow water passages, in southern regions, it is necessary to use soft water or distilled water to prevent scaling inside the water passages. In northern regions, it is essential to refill with genuine coolant (antifreeze) at authorized service stations or repair shops to avoid cylinder head corrosion.

Are Motorcycles Subject to National Emission Standards?

Motorcycles are required to comply with National IV standards. Implementation Plan for National IV Emission Standards: From May 1, 2018, the declaration of National III products was discontinued, with only National IV product declarations being accepted. After July 1, 2018, no further announcements for National III models were issued. When declaring National IV model announcements, new specifications and model numbers should be used to distinguish them from National III models. As the new standards have already specified technical pathways, National IV models no longer require separate recommended technical solutions and should strictly adhere to standard requirements. Starting from July 1, 2019, all National III products must complete product upgrades and transitions, with all National III product announcements revoked. All products sold and registered must comply with National IV emission standards. Background of National IV Implementation: Given that motorcycle emission control still has significant room for improvement, the Ministry of Environmental Protection established the National IV standards for motorcycles and mopeds to effectively control motor vehicle pollution, thereby promoting technological progress and structural optimization in the motorcycle and related industries.
