...placed in a thick steel cylinder. An hydraulic confining pressure is applied through a liquid, or at very high pressures through lead. The highest confining pressure used are about 300,000 pounds per square inch. In addition, a direct, differential pressure is exerted on the specimen by a steel piston. Different pressure used attain more than 1.500,000 pounds per square inch...
Most Diesel engines have high compression ratios of about 16-to-1. The upstroke of a Diesel piston compresses the air above it into one-sixteenth of its volume until its heat is something like 1,000° F. A drop of fuel is then sprayed into the cylinder head, and ignited by this heat. The resulting explosion forces the piston down in the power stroke...
Further weight reductions are indicated in General Motors' development of a two-cycle Diesel, which completes the four stages of operation-intake, compression. combustion and exhaust-in each up-and-down stroke of the piston, thus making every piston stroke a power stroke whereas four-cycle motors waste a full, powerless stroke on exhaust and intake...
