【Abstract】 The variable displacement
simulation models of the stop-valve for 1015 diesel engine are established
based on GT-POWER while determining the cylinder deactivation
strategy,pressurization system scheme,oil injection models and calculation
conditions.The calculation results show that using of the variable displacement
technology can improve the economy of 1015 diesel engine at low load.The range
of corresponding optimal working is found and Advantages and disadvantages of
the variable displacement...
