Abstract: The4L18E diesel engine is developed to meet
market.Several solutions for intake swirl rate,piston combustion
chamber,injection nozzles and different nozzle number and turbocharger are
designed for the purpose of optimization.Both emission reduction and low fuel
consumption are concerned so that it can be applied in GBⅢ vehicle.The model is verified
successfully in compliance the GB/T 18352 and GB/T17691.
