Key words: engines.

Features are considered of TNVD suction valve construction of main marine low speed diesel engines, type 9DKRN80/160-4 on ships, type Mercur 2. Analysis of the main diesel engine operation shows the cause of the low safety conditions at sea because of impossibility to provide the maximum low speed of the ship less than 8.5 or 9 knots because of essential defect of TNVD construction: no tightness between the suction valve body and the plunger liner. New construction decisions are offered for TNVD suction valves to increase reliability and efficiency of main diesel engines, minimum stable speed of main diesel engines is going to decrease.
