| Abstract: | Proper coolant flow distribution is beneficial to reduction of cylinder head thermal load,thereby improving head reliability,to minimum operation variation of each cylinder,and to cooling efficiency.Experimental study on distribution of coolant flow in a cylinder head was conducted to understand the cooling condition of head and to provide boundary conditions for later numerical simulation of coolant flow or verification.Pressure difference based on Pitot principle was adopted to measure the coolant flow fr... |
