[0046] The conventional internal combustion engines are reviewed. The fundamental tasks of an internal combustion engine are to induce flows of fuel and air into the engine proper, conduct the releasing of hidden heat energy of fuel by combustion, manoeuvre the media, products of combustion bearing the released effective heat energy, and transform the released effective heat energy flow into the power output of the engine. This is the working processes to be followed by any internal combustion engines. The working processes of conventional internal combustion engines were invented a century ago. There are two inherited defects: extremely low overall therno efficiency and very high weigh/power output ratio. It has limited the advance of transportation devices powered by conventional internal combustion engines. The OFHE internal combustion engine is a heat power unit. The overall thermo efficiency is much higher than that of conventional internal combustion engines, and the weight/power output ratio is much lower than that of conventional internal combustion engines. There are other advantages of OFHE TPH, internal combustion engine as power provider for transportation devices than the conventional internal combustion engines. Two methods are developed as foundation for the design and construction of OFHE internal combustion engine. TPHmax The first method provides the maximum power output T I" of OPHE internal combustion engines. The rational overall thermo efficiency of internal combustion engine TPHmax should be the ratio of actual power output of engine versus TP I . Under this criterion the overall thermo efficiency of conventional internal combustion engine is extremely low. The second method is the optimal feedback TPH,. of OFHE internal combustion engine, which makes the power output of OFHE internal combustion engine much greater than any comparable conventional internal combustion engines. The OFHE internal combustion can be applied in every transportation devices. The renovated transportation devices powered by OFHE internal combustion engine will have better performances, safety and convenience for passengers. The applications of OFHE internal combustion engine in transportation devices will initiate the new generation transportation system. OFHE internal combustion engine and renovated transportation devices powered by the OFHE internal combustion pollute less environment than comparable conventional internal combustion engines.
