Measurements of the piston temperature of high-speed internal combustion engines

Abstract

1. By means of this device, with impact contact, it is possible to measure piston temperatures with an error of±2.5°C, which is satisfactory for engine testing. 2. The device works reliably at high engine speeds (n=1500 rpm). The high reliability is ensured by the fact that,at transitional periods of the engine operation, the contacts can be placed in a nonoperating position. 3. The design of the device makes it possible to measure piston temperatures not only on experimental portions of engines, but on complete engines as well, which is very important, since the operation of a complete engine (especially a supercharged one) differs considerably from that of an experimental portion. 4. The basic elements of the device can be successfully used in designing and adjusting devices for measuring piston temperatures of complete high-speed engines, piston high-pressure compressors and piston gas generators.
