Addressing the challenges of dust and complex operating conditions faced by agricultural machinery in the field, a domestic company recently launched a dedicated air-cooled engine for agricultural machinery. This engine features a dust filter design that effectively prevents weeds and mud from entering the cooling system. It also boasts a reinforced cylinder structure, improving impact resistance by 22%, and can withstand the high-frequency start-stop requirements of tractors, harvesters, and other equipment. Its failure rate is 45% lower than that of ordinary air-cooled engines. Based on this, the company also offers customized services, adjusting engine power parameters according to different agricultural machinery models. Currently, it has partnered with five agricultural machinery manufacturers, and its products cover major agricultural production areas in Northeast and North China. Test data shows that agricultural machinery equipped with this engine increases operating efficiency by 18% and reduces annual maintenance costs by more than 2,000 yuan. With the advancement of agricultural modernization, the annual sales of this dedicated air-cooled engine are expected to exceed 50,000 units.
