Description

Technical field [0001] The invention relates to internal combustion engine technology, in particular to a dual-turbine internal combustion engine. technical background [0002] The current internal combustion engines mainly include crankshaft internal combustion engines and aircraft turbine internal combustion engines, which have three auxiliary power losses: intake, compression, and exhaust. However, because the crankshaft internal combustion engine uses the reverse torque of the torque to complete the three auxiliary actions, the loss effect is relatively large. In addition, because the piston connecting rod and crankshaft of the crankshaft internal combustion engine are connected in a zigzag structure, when the internal combustion engine is doing high pressure, the force arm is not really straightened, and it is pushed obliquely, which increases friction and pressure grinding. , The effective use of power is greatly reduced, and the residual heat of the crankshaft internal c...

AI Technical Summary

Problems solved by technology

However, since the crankshaft internal combustion engine uses the reverse force of the moment to complete the three auxiliary actions, the loss of efficiency is relatively large.

In addition, since the piston connecting rod of the crankshaft internal combustion engine and the three transmission components of the crankshaft are connected into a "zigzag" structure, when the internal combustion engine does work and explodes with high pressure, the moment arm is not really straightened, but is pushed obliquely, which increases friction and grinding , which greatly reduces the effective use of power. At the same time, the residual heat of the crankshaft internal combustion engine is high, and the heat utilization rate is low. If it is not for the heat dissipation outside the cylinder, the temperature of the residual heat will be higher, and the force arm of the crankshaft internal combustion engine is difficult to expand due to structural and space constraints.

The above reasons cause more than 50% of the energy and fuel to be discharged as exhaust gas, which not only affects the energy conversion rate, but also pollutes the environment, and its power and volume are relatively small

Although the current aircraft turbine internal combustion engine has a high speed, due to its extremely complex structure, the requirements for materials are particularly high, and the energy conversion rate is only about 20%. No matter from the perspective of energy saving or environmental protection, it is urgent to develop new Turbines to change the status quo
