New apparatus to raise the performance of engine cooling water cycle [electronic resource]

Internal combustion engines consider as a power source of all machines in agricultural operations. To obtain the optimum performance of these engines there temperature must be maintained at the optimum level. To achieve the previous aim, the engine cooling system must be responsible for the absorption of excess heat from the engines particularly in hot regions. Therefore, -this study was conducted in order to solve a problem of failure engine water cooling cycle in warm areas by appending an additional unit to the engine cooling water circuit consisting of an additional thermally insulated tank of water cooled by two pieces of peltier sheets and electric cooling fans. When engine temperature rise above the allowed level, the cooling water path throw the assistant cooling appanitus (peltier cooling unit) to maintain the engine temperature at the ideal level. Four main parameters were taken in this study, five levels of electric current intensity CI (1, 2, 3,4 and 5 Ampere), four levels of water flow rate FR (0.5, 1, 1.5 and 2 liter/min.), four levels of temperature of inlet water WT (75°. 80°, 85° and 90°C). and two types of flow water FT (free flow and inserpentine).
