Product Description

Product Introduction

The Deutz Air Cooled Diesel Engine F4L912 is a four-cylinder air-cooled diesel engine engineered for high reliability and extreme environments, delivering exceptional performance in industrial power applications. Its modular design with individually arranged cylinders ensures high parts commonality, significantly reducing maintenance complexity and costs. With a compact structure, it saves installation space and adapts seamlessly to integration in compact equipment. The air-cooling system eliminates the need for coolant circulation, fully avoiding issues like leaks, freeze cracks, and scaling, enabling stable operation across a wide temperature range of -40°C to +50°C. This makes it ideal for water-scarce or harsh climates, such as deserts and plateaus. Technically, it features a 3.77L displacement, with the naturally aspirated version delivering a maximum power of 51kW at 2500rpm and a peak torque of 270N·m at 1650rpm. Its low-speed high-torque characteristics excel in heavy-load conditions. Additionally, an integrated air heater ensures reliable cold starts, while an optimized shock-absorbing housing and low-noise design (noise level below 85dB at one meter) enhance operational comfort.

 

The F4L912's adaptability and durability make it a core power solution across diverse scenarios. In agriculture, it powers tractors and harvesters, meeting the high-load demands of field operations. In construction, it equips small excavators, loaders, and other machinery for flexible and efficient performance. Its high-altitude capability (stable operation in oxygen-deficient environments) makes it a top choice for civil air defense projects and generator sets in remote areas-for example, 30kW air-cooled generator sets that provide continuous power without relying on water sources. The engine also sees wide use in industrial pumps, marine auxiliary power, and similar applications, such as in generator sets by BeiNei Deutz and construction equipment by Weifang Aofeng Power. Its modular design supports rapid adaptation to different devices, while its compliance with China Stage II emission standards ensures competitiveness in markets with lower regulatory requirements. Whether delivering stable performance in extreme climates or powering complex workloads, the F4L912 exemplifies Deutz's technical expertise in air-cooled diesel engines.
