Title: 2-cycle engine
Inventor: HIRATA MAKIZOU
IPC: F02B75/02
Filed: 1982-08-19
Abstract: PURPOSE:To improve combustion efficiency by the formation of strong swirling flow, by effectively discharging the combusted gas in the concaved part on the upper surface of a piston by the swirling flow in the space formed with said concaved place and with a guide groove when the piston approaches top dead center, thus increasing the scavenging efficiency. CONSTITUTION:A spherical concaved place 16 is formed on the upper surface 5a of a piston 15, and a combustion chamber 22 is set in nearly semispherical form having a spark plug 23 as center, and thus flame propagation distance, namely combustion time is reduced, and combustion efficiency is improved. When the piston 15 rises and comes close to the concaved place the top dead center, a compression force is generated, and the mixed gas flow A which flows towards the bottom part of the concaved place 16 from the outer peripheral part of the piston 15 and the mixed gas flow B which is directed upward the concaved place 16 from the outer perhiphery of the piston 15 are formed in a guide groove 25. Thus, a strong swirling flow 29 is formed on ignition time, and agitation of the mixed gas is accelerated, and combustion efficiency is improved.

Abstract: PURPOSE:To give warning to the user so that no exposing error due to the erroneous displaying of the aperture value occurs by providing a discriminating means, an abnormality detecting means, a displaying means, etc. CONSTITUTION:From the output of the photometric cell at the time of the preview mechanism operation, a certain constant value DELTAPv is subtracted as a preview correcting quantity, and the error of the displaying and exposing control during the preview mechanism operation is minimized as much as pos sible. The result of the correction is a curve C. The curve D shows the relation of an F value and an output Pa of the photometric cell when the interchange able lens of an open aperture value (F value) 2.8 is loaded. Usually, for the cell output Pa in the open aperture photometry when the interchangeable lens is loaded, compare with the case the reference lens is loaded, both are different only by an open aperture photometry error Wvi. Consequently, this is corrected, the automatic exposing adjustment is executed by the open aperture photometry and the correcting result is a curve E. At the time of the open aperture photome try, the error Wvi is corrected, and during the preview mechanism operation, a preview correcting quantity DELTAPv is corrected, but the error Wvi is not corrected.
