The article presents the substantiation of efficiency of sea transport in the world transport system. The main condition of ensuring water safety is equipment of ships with fail-safe and effective collective life-saving equipment (CLSE). Today the standard rescue operation when using CLSE is a series-parallel action of the ship’s crew, where the ship is sinking on an even keel, or with a slight roll to one side. It has been stated that such cases are extremely rare. As a rule, the situation develops rapidly. Accident statistics disposes to developing the modern approaches to the safety of human life at sea. There are two directions for safety ensuring. One of them is the development and implementation of artificial intelligence systems for CLSE, when CLSE independently, without human control, responds to the emergency with greater probability of the ship loss and the crew death. Another direction is when there is no need to save the crew (in case of unmanned ships). There are considered the Russian diesel engines for the lifeboats: specialized marine diesels 4CHSP9.5/11 - Caspiy 30M and 4CHSP9.5/11 - Caspiy 40. Both engines are equipped with a dual start-up system - manual and electric starter, they have a reverse gear transmission, a single-circuit flow-through sea water cooling system, decompression devices and standard mounted units, ac-cording to the requirements of the International Convention of Saving Life at Sea (SOLAS) and the International Code of Life-Saving Appliances (LSA Code). In modern environment, the scientific foundations and technical solutions are being developed to ensure the reliable start-up of swirl-chamber diesel engines by exposing the fuel to physical fields, without using glow plugs

The paper considers the diesel engines as the hearts of the lifeboat power plants of all types of vessels: sea, river and mixed navigation, according to the International Convention on the Protection of Human Life at Sea - SOLAS. In the Russian Federation there are two types of engines produced for this purpose: 4-9.5/11 (“Kaspiy 30”) with vortex-chamber mixing and 4-9.5/11 (“Kaspiy 40”) with a combustion chamber in piston and volume-film mixing. The Kaspiy 40 engine is characterized by good starting properties and does not require additional acceleration of the launch. The Kaspiy 30 engine, due to the design of the combustion chamber, must be equipped with a fuel mixture heating device in the combustion chamber, which must work before the engine reaches a stable mode of operation. This device is glow plugs powered by a rechargeable battery and connected sequentially, so that failure of one plug entails the inoperability of the entire chain. If the rescue operation is necessary, the lifeboat engines must be started on deck without a coolant (sea water) in the cooling system and must work for at least 10 - 15 minutes until the crew gets into the boat and the boat is launched, after which the cooling system will take the sea water. If the glow plug system fails, especially when the ambient temperature is low, the start of the engine in the prescribed time may not take place at all. There has been studied the effect of magnetic treatment of fuel before the launch and during the launch on the activation energy of fuel molecules and their reaction in the combustion without external heat

Diesel engines is generally used for industrial and agricultural machines. Few people care about the engine temperature so it is forced to reach temperature of 100oC, which causes overheating of the diesel engine and has an impact on the performance itself. This also uses a hopper cooling system which is certainly not effective, because it's necessary to see that the water in the reservoir is still or not, also not equipped with an engine temperature display so it's difficult to ascertain the temperature inside. This study aims to monitor and control the temperature of cooling water. Operation of temperature control uses a telecontrol system that is connected to network (Internet of Things) so diesel temperature control can be done remotely. Monitoring of temperature and water level in the reserve tank using Web Mobile. In addition, there is a temperature sensor that is used to measure the temperature of the cooling water so that users can monitor the temperature of the diesel engine on Web Mobile. The test results obtained, the temperature sensor has an average temperature reading error of 0.031004%. Diesel engines with controlled solenoid valve cooling systems can produce ideal temperatures compared to when the solenoid valve is open (using the radiator continuously) or when the solenoid valve is Closed (without using a radiator). When the solenoid is controlled the engine temperature can be ideal because the solenoid valve opening and closing system has the lowest temperature of 56.34oC and the highest temperature of only 80.85oC.

In the field of diesel engine components, ceramic glow plugs assisting quick start up of chamber diesel engines had been developed in September, 1981 and ceramic swirl chambers followed in commercialization in April, 1983. These ceramic components are currently under commercial production and are installed on passenger cars on the merket. Silicon nitride (Si3N4) is the material of these components, and a lot of mass-production technique has firmly established in order to achieve competitive price and high durability in comparison with the conventional metal components. Because of its excellent heating characteristics, ceramic glow plugs have eliminated the “waiting time” before the start-up of diesel engines. As the result, drivers can enjoy quick starting of engines as they can do with gasoline fueled vehicles. Ceramic swirl chambers could drastically reduce idling noise of diesel engines and remarkably improved starting performance in the cold climate operation.

To ensure optimal temperature conditions during casting cycle the pressure casting moulds are equipped with cooling systems. These days the cooling systems used in the most of Czech foundry plants enable pre-heating of pressure casting moulds to the working temperature before start-up of production and during casting operation to keep optimal temperature balance among the casting and the mould. Pressure casting mould temperature balance is provided by system of mutually connected channels which are mostly parallel with parting line and inside those the heat transfer medium flows. However such a system allows removal only limited heat amount from the most overheated places of the casting mould and does not allow heat removal from cores of small diameters. This inhomogeneous heat removal causes porosity of the casting in certain areas and also lifetime of the pressure casting mould is dramatically reduced. Cooling by means of liquid CO2 was developed as one of the new cooling possibilities for such places in the pressure casting mould where the heat is concentrated and for standard cooling systems it is too complicated to fully control the heat processes there. The paper deals with the behaviour monitoring of the new cooling system utilizing the potential of liquid CO2. This system was applied into pressure casting mould core and its final impact on the casting quality in the close surrounding was observed.
