Compression ratio |
Compression ratio refers to the ratio of the total volume of the cylinder to the volume of the combustion chamber, which indicates the degree to which the gas in the cylinder is compressed when the piston is moved from bottom dead center to top dead center. Compression ratio is an important parameter to measure the performance index of automotive engines. In general, the greater the compression ratio of the engine, the higher the pressure and temperature of the mixture gas at the end of the compression stroke, and the faster the combustion rate, the greater the power of the engine and the better the economy. However, when the compression ratio is too large, not only can it not further improve the combustion condition, but it will cause abnormal combustion phenomena such as detonation and surface ignition, which in turn will affect the performance of the engine. In addition, the increase in engine compression ratio is also limited by exhaust pollution regulations. |
Description:
Ammonia is a kind of alkaline substance, it has corrosion and irritation effect on the skin .When we breathe, the Ammonia can enter the alveoli ,and through the alveoli into the blood. It combined with hemoglobin,destroy the oxygen flow capacity in the body,it can be irritating and Corrosion of the upper respiratory tract of the animal or human,weaken the body's resistance to disease. The ammonia in air comes mainly from the following two aspects:
1.Additive containing urea and ammonia which in Anti-freezing concrete wall of Construction
2.Additives and bleaching agent of interior decoration materials
The feature of our Self-developed ZF Ammonia removal is we add Non-volatile ion into adsorbent,it made the ZF ammonia removal combined with ammonia to generate solid inorganic salt, then release hydrocarbon anion ,to catch NH4+ in the air,it overcomes the drawback of pure activated carbon adsorption
