Cascaded Charge Air Cooling for PC Diesel Engines

Regulation and control in cooling systems of internal combustion engines

“…The amount of heat given off by the cooled surfaces of the parts to the coolant is determined by the Newton-Richman equation (1) where -heat transfer coefficient, -area of the cooled surface of the part, -average temperatures of a part and coolant, respectively. The heat transfer coefficient depends on the nature of heat transfer at the wall-liquid interface, the temperature of the wall and the liquid , the pressure in the system and the speed of the liquid relative to the wall .…”

“…Maintaining the optimum temperature level of marine diesel engines can be achieved by improving regulation methods and introducing regulation and control systems that implement these methods. When creating such systems, it is necessary to take into account the tendency to increase the temperature level of ICE cooling [1,2] and the ever-wider introduction of high-temperature cooling systems (HTCS), which provide an increase in the economic and resource indicators of diesel engines [3][4][5][6]. The work [7] provides information on engines of such manufacturers as MAN B&W Diesel Ltd, Caterpillar, General Motors, Wartsila/Sulzer, Deutz AG, Barnaultransmash OJSC, in the power range from 110 to 3680 kW, with cylinder diameters from 146 to 457 mm, and a crankshaft speed of 277 to 2200 rpm.…”
