Title: Direct injection type two cycle diesel engine
Inventor: SATO TAKESHI
IPC: F02B75/02
Filed: 1990-09-06
Abstract: PURPOSE:To perform a loop scavenging while to generate a swirl in a cavity by connecting a fresh air guide groove formed on a piston top face into the cavity as a tangent-line to a cavity peripheral wall surface. CONSTITUTION:A fresh air guide groove 15 is formed on a top face 2a of a piston 2 so as to guide a part of fresh air flowing in a loop form into a cavity 14. The fresh air guide groove 15 is connected to the cavity 14 as a tangent-line of a peripheral wall surface of the cavity 14. A swirl around an axis of the cavity 14 is generated by a part of the fresh air guide by the fresh air guide groove 15. The remaining fresh air flows inside a combustion chamber in a loop form to scavenge combusted gas. It is therefore possible to perform a loop scavenging so as to generate a swirl in the cavity 14.

Abstract: PURPOSE:To attain synchronization by applying masking to a composite synchronizing signal when a specific signal is added between horizontal synchronizing signals and fetching a composite synchronizing signal not through a mask circuit when a noise signal is included. CONSTITUTION:In the case of the synchronizing circuit in which a horizontal synchronizing signal and a vertical synchronizing signal are obtained from a composite synchronizing signal, masking is applied to the composite synchronizing signal to obtain a masked composite synchronizing signal from which a specific signal is eliminated when the specific signal is added between the horizontal synchronizing signals of the composite synchronizing signal and the added period of the specific signal is limited to a prescribed period with respect to the vertical synchronizing signal.
