摘要:随着科学技术的不断发展，工业的不断壮大，导致能源资源逐渐减少。废弃物品数量、种类不断增多。废弃物品的回收、再利用和开发新能源已经成为当务之急。我国汽车报废逐渐凸显，每年都会有很多废弃的发动机，不仅浪费了资源，也造成了环境的污染。本设计通过对小型汽车报废的四缸发动机进行研究，改装发动机气门凸轮的控制顺序，使原发动机四冲程通过改装后变为二冲程，即吸气、和排气相对应抽水机抽水时的吸水、排水，实现发动机活塞抽水的能力，达到了废物利用的目的。同时动力来源采用自适用式风力驱动系统。改装后的发动机采用风力作为动力来源，有效利用风能资源，减少对不可再生资源的消耗，降低对环境的污染。本设计适用于农田灌溉，蓄水等长期连续性工作。

ABSTRACT:Along with the development of science and technology, industrial expansion, lead to gradually reduce energy resources. Junk quantity kinds grow. Junk recovery, reuse and development of new energy has become a top priority. In China's automobile scrap gradually highlights, every year there are many abandoned engine, not only waste the resources, also caused the environmental pollution. This design through for small cars discard of the four cylinder engine for research, to modify engine valve CAM of control sequence, the four stroke engines by modified into a two-stroke, namely the suction, exhaust and corresponding pumping water pump of water supply, drainage, realize engine piston pumping ability, achieve the purpose of using the waste. At the same time using the source of power for type wind drive system. The engine after modification by wind as power sources, effective to use the energy resources, to reduce the consumption of non-renewable resources, reduce the pollution to the environment. This design practical in irrigation and water storage and work for a long time continuously.
