The HC Percentage of two-stroke gasoline engine emmission is higher, and the main reasons are as follows: 1. More fresh gasoline-air mixture is exhausted from the chamber during operation compared with that of four-stroke engines. 2. More waste gas remains in the cylinder so that the burning efficiency is lowered. The improve methods are increasingthe air-fuel ratio A/F at idle speed, determining the best ignition advance time angle increasing idle speed, etc. After the test, it's found that the emmission...

The HC Percentage of two-stroke gasoline engine emmission is higher, and the main reasons are as follows: 1. More fresh gasoline-air mixture is exhausted from the chamber during operation compared with that of four-stroke engines. 2. More waste gas remains in the cylinder so that the burning efficiency is lowered. The improve methods are increasingthe air-fuel ratio A/F at idle speed, determining the best ignition advance time angle increasing idle speed, etc. After the test, it's found that the emmission at idle condition can be clearified by raising the air-fuel ratio. Decreasing the advance timing angle and increasing the idle speed properly assure stable idle operation after the air-fuel ratio increased. It is effective for lower the idle emmission of CY80 Motorcycle that redetermine the air-fuel ratio ignition advance timing angle and the idle speed.

二冲程汽油机怠速HC排放高的主要原因是:1)新鲜混合气的逃逸损失比四冲程汽油机的大,2)缸内残余废气较多,影响燃烧质量;可以通过增大怠速时的空燃比A/F,确定最佳点火提前角、提高怠速转速等措施改善;试验表明,在不改变原机结构的情况下,提高空燃比是降低HC和CO排放的有效措施,减小点火提前角,适当提高怠速转速是空燃比提高后怠速稳定运转的保证;重新确定空燃比、点火提前角及怠速转速,对降低CY80型摩托车的怠速排放效果显著。

Peat shaped-coal includes peat fuel brick,peat honeycomb briquet and peat stick etc. It is a new type of fuel which is processed by using the main raw material of herbaceous peat whose reserves are rich in china.The product is of good burning performance. Its burning temperature and burning efficiency are equel to the criterion of medium commercial coal. Peat coal has some advantages. for example,the resources of its raw materits are rich, its cost is cheap, its producing technology is easy, the factory building's investment is little ,its so-called two benefits are notable and there are no pollution of so-called the three wastes from it. Therefore,it is a prospect that we would apply peat coal widespreadly,and it is of great significance,especially in the region of lacking coal and forest.

泥炭型煤(包括泥炭燃料砖、泥炭蜂窝煤和泥炭棒等),是利用我国储量丰富的草本泥炭为主料加工制成的新型燃料,该产品具有良好的燃烧性能。燃烧温度和燃烧效果相当于中等商品煤的指标。泥炭制型煤具有原料来源丰富、成本低廉、工艺简单、建厂投资少、见效快、“两效益”显著,又无“三废”污染。所以具有广阔的应用前景,尤其对缺煤少木地区,其意义重大。

This paper puts forward the idea that, in the cqurse of the design of the circulation in a boiler for the most efficient burning,two factors should be taken into consideration. They are the choosing of the practical chamber-height and the setting of the circulative rates.Therefrom,this paper draws the formula of the pos-sible smallest height of the chambers of the circulative boilers and also the formula of the relation between the burning efficiency and the circulative rates.
