Summary

The global Air-cooled Diesel Engines market size was US$ 691 million in 2025 and is forecast to reach a readjusted size of US$ 853 million by 2032 with a CAGR of 3.1% during the forecast period 2026-2032.
Air-cooled diesel engines are diesel engines that rely on air flow for cooling instead of a liquid cooling system. Unlike water-cooled engines, they do not require a complex coolant system; instead, heat dissipation is achieved through air circulation around the engine. This design simplifies the structure, reduces maintenance costs, and increases reliability. Air-cooled diesel engines are known for their high-temperature resistance, low maintenance needs, compact design, and reliability, making them widely used in agricultural machinery, construction equipment, generator sets, and some vehicles, particularly in areas with harsh conditions or limited access to stable water sources.
In 2025, the North America Air-cooled Diesel Engines market was US$ million, while the Europe market stood at US$ million. North America accounted for % of the global market in 2025 and Europe for %. Europe’s share is expected to reach % by 2032, corresponding to a CAGR of % over the analysis period.
Major global manufacturers of Air-cooled Diesel Engines include Yanmar, Kohler Power, Kubota, Generac, Changchai, Hatz, Chongqing Fuchai, Mitsubishi Heavy Industries, Greaves Cotton, Golden Fiying Fish Diesel, among others.
