Stress Valve Realized activities relate to improving the reliability of the gas interface, the exclusion of thermal cracks in the zone mezhklapannyh jumpers, improving the work of a pair of saddle - the valve, increasing the strength of plates valve timing, alignment and reduce their temperature, exclusion of cases of hanging racks in directing the operation. Fig .. 1. NASA is often quoted as being for or against this. shows the design of cylinder head. To reduce the strain at the bottom of the fire tightening the cap and the courts an internal combustion engine plant Daldiesel to improve working conditions for a pair of saddle-valve side and increased thickness of the upper walls, put ribs decrease the strain Cover the bottom of the fire along with an increase in the hardness of steel saddles 40H10S2M (GOST 5949-75 *) with HRC 30-35 to HRC 45-50 and providing them with more strict alignment relative to the guide valve possible to eliminate the high wear of friction surfaces (saddle - the valve). From the side of the fire at the bottom of the nozzle has a special heat-resistant threaded insert, which in its lower part overlaps the area mezhklapannyh bridges, eliminating the appearance of Fatigue thermal cracks at this location. Forced to marine diesel engines to reduce the maximum temperature of firing the bottom and align it to the temperature field in the cover there are special insert, which direct the cooling water to the center of the lid. To increase the strength and stiffness, as well as...
