摘要：A high precision, high antijamming multipoint infrared telemetry system was developed to measure the piston temperature in internal combustion engine. The temperature at the measuring point is converted into corresponding voltage signal by the thermo-couple first. Then after the V/F stage, the voltage signal is converted into the frequency signal to drive the infrared light-emitting diode to transmit infrared pulses. At the receiver end, a photosensitive audion receives the infrared pulses. After conversion, the voltage recorded by the receiver stands for the magnitude of temperature at the measuring point. Test results of the system indicate that the system is practical and the system can perform multipoint looping temperature measurements for the piston.

摘要：分析了内燃机升功率对活塞热负荷及机械负荷的影响，明确了活塞变形是造成活塞机械应力集中的主要影响因素的观点，提出了采用大内冷油道薄壁框架结构并配合短活塞销，以减小活塞变形并强化活塞顶部冷却，从而降低并协调活塞热负荷及机械负荷的新设计思路。将此设计思路应用于高升功率柴油机铸铁活塞的结构设计中，并对新设计活塞进行了三维接触问题的有限元计算分析。
