FL513 series air-cooled diesel engine structure introduction Deutz FL513 series diesel engine (as shown in Figure 1-8) marks the beginning of a new era of air-cooled diesel engines. This series of diesel engines uses independent cylinder liners with heat sinks and a one-cylinder-one-head modular structure. The parts are highly versatile and have a wide range of uses.

With the gradual application of electronic technology, the environmental adaptability of diesel engines has gradually increased. Compared with the FL413F series diesel engines, the technical progress of the FL513 series diesel engines mainly includes the following aspects.
(1) Improvement of combustion chamber The FL513 series air-cooled diesel engines have undergone major changes in the structural shape of the combustion chamber (compared with the FL413F model). The combustion chamber of the non-supercharged model has been improved from an oblique cylindrical (U) combustion chamber to a W-shaped combustion chamber; although the supercharged models all have W-shaped combustion chambers, their structural dimensions have changed significantly, as shown in Figure 1-9.
Through the improvement of the combustion chamber, the diesel engine’s combustion system has been improved and the combustion has been more complete, thus greatly improving the various performance indicators of the diesel engine.

(2) Improvement of the fuel supply system
①The A-type pump was changed to a P-type pump, which increased the pump oil pressure (the plunger diameter was increased).
②Injector nozzle improvement. The nozzle holes of the non-supercharged diesel engine were changed from 2 holes to 4 holes, and the injection pressure was increased.
③Reduced fuel consumption and improved torque characteristics, as shown in Figure 1-10.
(3) Improvement of output power
The FL513 model basically retains the basic structural features of the FL413F model: V-type 90° angle, also divided into inline 5, 6 cylinder, V-type 6, 8, 10, 12 cylinder supercharged and non-supercharged models. The turbocharged diesel engine has reduced its rated speed (from 2500r/min to 2300r/min) by improving the combustion mode and the injection pump system, while the non-turbocharged diesel engine has reduced its rated speed (from 2500r/min to 2300r/min) by increasing the cylinder diameter (from 125mm to 128mm), improving the fuel supply system (injection pump) and the combustion mode. The rated power has not only remained unchanged, but also widened the power output range of the diesel engine, thereby greatly improving the adaptability, reliability and service life of the diesel engine. In addition, the overall noise of the diesel engine has also been reduced. The power comparison curve of the BF8L513 and F8L413F diesel engines is shown in Figure 1-11. (4) Improvement of exhaust emission indicators After a series of improvement measures, the exhaust indicators of the FL513 model have been greatly reduced compared with the FL413F model, as shown in Figure 1-12. The emission indicators of the FL513 model have been greatly improved and can meet the requirements of the Euro II standard.
