As one of the world's oldest engine manufacturers, DEUTZ occupies an important position in the field of diesel engines thanks to its profound technological accumulation and continuous innovation. Deutz 4-cylinder engine series has become the core power choice for construction machinery, commercial vehicles and power generation equipment due to its efficient performance, reliability and wide applicability.
1. Technical characteristics: a model of engineering that balances performance and efficiency
The Deutz 4-cylinder engine is designed around the three core concepts of efficiency, reliability and environmental protection. The BF 4 M 2011, for example, achieves a high power output of 68 kW/2,800 rpm and a 15% improvement in fuel economy through advanced combustion chamber design and optimization of the fuel injection system. Its turbocharging technology (as in the TCD 2.9 L4 model) delivers a maximum torque of 300 N-m at low speeds (1,600 rpm), which significantly enhances the vehicle's acceleration and hill-climbing ability.
In terms of environmental protection, DEUTZ four-cylinder engines generally comply with Euro IV and higher emission standards. For example, the BF 4 M 2011 reduces NOx emissions by more than 30 percent through exhaust gas recirculation. In addition, the modular design simplifies the maintenance process and increases the efficiency of component replacement by 40%, significantly reducing downtime.
2. Product range: Diverse models to meet segmented needs
The DEUTZ four-cylinder engine family covers a power range from 25 kW to 68 kW, adapting to the needs of different scenarios:
F 4 L 2011: Focusing on the construction machinery sector, the 26 kW/1500 rpm power rating and 94 x 112 mm bore stroke design ensure high pressure resistance and stability.
TCD 2.9 L4: with turbocharging technology, the combination of 55.4 kW/2600 rpm power and 92 x 110 mm bore stroke is suitable for commercial vehicles with high power requirements.
G2.9 L4: Compact design (dimensions not disclosed), 54 kW/2800 rpm output and 215 N-m torque for space-constrained power generation and light machinery.
BF4L913: air-cooled design, optimized for gensets, with 50 kW power rating and air-cooling system for continuous operation in high-temperature environments.
The technical characteristics are also reflected in the model designation rules. Taking BF6M1013-28E4 as an example, “B” stands for exhaust gas booster, “F” for four-stroke high-speed engine, “M” for water-cooled. M” is water-cooled, and ‘28’ corresponds to 280 horsepower.
3. Application scenarios: cross-industry adaptability
Deutz four-cylinder engines are widely used in many fields due to their flexibility:
Commercial vehicles: FAW Jiefang J5/J6 series are equipped with DEUTZ four-cylinder engines, which can meet the needs of urban transportation and medium- and long-distance freight transportation.
Construction machinery: Loaders and excavators rely on the high pressure resistance and low-speed torque output of models such as the F 4 L 2011.
Power generation equipment: The BF4L913 air-cooled engine, with its 50 kW output and IP22 protection rating, has become the first choice for emergency power and power supply in remote areas.
Agricultural machinery: The small size and low vibration characteristics of the G2.9 L4 make it suitable for combine harvesters and tractors, enhancing operational comfort.
Deutz's core competence is not only based on technology, but also on its global service network. As the world's first engine manufacturer (founded in 1864), its products are available in more than 130 countries through 13 distribution companies and more than 800 service locations. 4-cylinder engines from Deutz realize a multi-dimensional balance of performance, efficiency and reliability through technological innovations and scenario-based design. From the power of commercial vehicles to the core of gensets, its products not only meet the needs of diversified markets, but also respond to the trend of sustainable development with a global service network and environmentally friendly technologies.
