Wide application of water-cooled engines
The feasibility of applying a water-cooled engine to a desert area focuses on the test of the long thermal performance of the engine in the harsh environment of the Shaqi area. The engine environment is dissipated. The oil resources of the Taklima Desert in the Tarim Basin of Xinjiang are extremely rich, but its exploration and development tasks are quite arduous. In addition to the special equipment needed to extract oil, the transportation of desert vehicles with transport personnel and special equipment is a key issue to be solved urgently. China's heavy-duty truck group introduced the Steyr heavy-duty truck from Austria. The vehicle has a wide range of power coverage. At present, most of the assembly components have been localized, which provides good conditions for the development of heavy-duty desert vehicles. Constant speed cylinder diameter stroke maximum torque short cylinder displacement maximum torque speed compression ratio minimum ratio fuel consumption cluster test research steps Desert climate conditions are harsh, the ambient temperature is as high as 70 surface temperature. In the first step, the original machine is tested at high ambient temperature, and the necessary data is obtained. The second step is to redesign the main part according to the first round of test results, and finally the engine can adapt to the desert environment. Simulation of the desert environment Given the geographical environment of the desert, the tests must be carried out in a laboratory with environmental simulations. However, due to limited conditions, the general laboratory was modified to simulate the desert environment. The simulated intake air simulation of the engine intake is mainly that the intake air temperature is in accordance with the working condition of the engine in the desert area. For this purpose, the intake air heating method is adopted to increase the intake air temperature to the required temperature, and the vapor from the boiler passes through the transmission pipe. The road enters the heat exchanger, and the condensed water which is heated by the air vapor heated into the heat exchanger flows into the pool, and the heated air enters the engine through the air flow controller and the air filter. After the environment simulation engine is working for a period of time, the ambient temperature is high, but the uniformity is poor. In order to ensure a realistic simulation of the environment in the desert area, two sets of radiators were installed in the laboratory, and the air was stirred by a fan to make the indoor air temperature as uniform as possible.
