In the design and construction of the diesel engine noise reduction program should be considered the minimum necessary to the normal operation of the unit into and out of the air volume and emission standards must not exceed the rated allowable backpressure backpressure values ??and other factors, otherwise it will seriously affect the unit power output, so that a higher temperature maintenance unit diesel engine, frequent failure or shorten the life of the diesel generator set. White Dragon BLZH190 Diesel Products: Type: Water-cooled horizontal single-cylinder direct-injection four-stroke cylinder diameter (mm); 90 of the piston stroke (mm): 90 Starting method: hand start four-stroke diesel engine works by the compression stroke of the second stroke - - compression. When compressed between the piston from the bottom dead center dead center, the stroke of the function has two, one is to increase the air temperature, fuel combustion to prepare themselves: the second is to create conditions for gas expansion work. When the piston up, after the intake valve closes, air within the cylinder is compressed as the volume of the continuous small, the air pressure and the temperature will continue to rise in the price of diesel engines, the compression pressure and compression end of the air humidity and about , i.e. the compression ratio, generally the compression end pressure and temperature as: Pc = 4 ~ 8MPa diesel engine parts, Tc = 750 ~ 950K. Diesel auto-ignition temperature of about 543-563K, compression end temperature than the temperature of the high number of spontaneous combustion diesel engine, enough to ensure their own fuel injected into the cylinder ignition combustion.
