Founded in 1995, China Dongda Power Industry Co., Ltd. is one of the few internal combustion engine, ic engine manufacturer and distributor in China that has patents on the generator, motor, power supply, engine, alternator, diesel and gearmotor design, supply and sale. Our custom internal combustion engines, ic engines has obtained the certifications of ISO9001-2000, GS/TUV, CE, VL, EPA, QHS, SON, CAP and SRS and we have won EPA 2005 Motor Year Certification. Our 30 QC staff carefully performs inspections at every stage of production, from the time we receive raw materials to packaging. Noise, power, and stability are tested to ensure that our engines can endure 580 hours of constant use. We also can design and deliver OEM/ODM samples in one month.

For the forty years following the first flight of the Wright brothers, airplanes used internal combustion engines to turn propellers to generate thrust. Today, most general aviation or private airplanes are still powered by propellers and internal combustion engines, much like your automobile engine. On this page we will discuss the fundamentals of the internal combustion engine using the Wright brothers' 1903 engine, shown in the figure, as an example.

Overall dimensions (LxWxH) (mm): 670x589x644. Type: in line 4-Cylinder, Water-cooled, DOHC, TB/Gear drive, 16 valve mechanism, Pentroof combustion chamber, EIS, Multi-point sequential injection
Bore x Stroke (mm): 80.5x78. Total displacement (L): 1.588. Compression ratio: 9.5. Max. net power (kW/rpm): ≥68kW/6000rpm. Max. torque (N.m/rpm) (net): ≥130N.m/2600-3000rpm. Min. fuel consumption ratio under full load (g/kW.h): ≤285. When discussing engines, we must consider both the mechanical operation of the machine and the thermodynamic processes that enable the machine to produce useful work. The basic mechanical design of the Wright engine is remarkably similar to modern, four-stroke, four cylinder automobile engines. As the name implies, the combustion process of an internal combustion engine takes place in an enclosed cylinder. Inside the cylinder is a moving piston which compresses a mixture of fuel and air before combustion and is then forced back down the cylinder following combustion.
