Air-injection engines use a blast of highly compressed air to blow the fuel into the cylinder. 空气喷射发动机利用一股高压气体将燃料吹到气缸内。
Diesel engines are divided into air-injection engines and solid or mechanical injection engines. 柴油机分为空气喷射发动机和固定喷射或者机械喷射发动机。
Air-injection displacement experiments on the crude oil of Hu-12 block have been conducted at different pressures and temperatures. 针对胡12块油藏原油,研究了不同压力、温度下注空气动态驱油情况。
The results of experiment showed that the time of gas breakthrough was shortened, and oil displacement efficiency and oxygen content in produced gas were reduced with increase of air-injection pressure at the same temperature. 实验结果表明,在同一温度下,随着注入压差的增大,气体突破时间缩短,突破驱油效率及含氧量降低;
Because the oxygen was consumed to form CO 2, the CO 2 content was up to 8% in the produced gas; an indirect flue-gas drive was realized in the process of air-injection; 氧气在油层中被消耗,生成了CO2,采出气中CO2含量高达8%,注空气过程实现了间接的烟道气驱;
New purifying apparatuses, such as air filter in constant-temperature inlet, second air-injection system, catalytic converter, exhaust recycling system, crankcase ventilation apparatus and gasoline vaporization control system can reduce the forming of harmful emissions to purify automobile emissions. 恒温进气空气滤清器、二次空气喷射系统、催化转换器、排气再循环系统、曲轴箱通风装置及汽油蒸发控制系统等新型排气净化装置,可以抑制有害排放物的产生,使汽车排气得到净化。
