抄録

An optically accessible small DI diesel engine has been developed, which enable the shadowgraph observation with an elongated piston under high speed and heavy load conditions. The tolerable maximum engine speed and in-cylinder pressure are 4000rpm and 12MPa, respectively. The key techniques of this engine are sapphire window, ceramic coated upper piston and seamless resin oil-scraper-rings. The sapphire window decreases the weight of the elongated piston while keeping the enough strength. The ceramic coating realizes non-lubricating operation for the upper piston. The seamless resin ring prevents the lube oil in the crank case from dispersing on the optical mirrors.
