abstract

A new turbo-charging system, named AVIEIT (automatically variable intake exhaust injection timing), is proposed. Its main purpose is to improve the performance of low speed high torque operating conditions and improve the economy of high speed operating conditions for high-speed supercharged inter-cooled diesel engines. The principle of the AVIEIT turbo-charging system is presented. A control mechanism for the proposed AVIEIT system used for a truck diesel engine is introduced. An engine simulation code has been developed. In this code, zero-dimensional in-cylinder combustion model, one-dimensional FVM-TVD (finite volume method-total variation diminishing) model for unsteady gas flow in the intake and exhaust manifold, and turbocharger model are used. The developed code is used to simulate the performances of diesel engines using the AVIEIT system. Simulations of a military use diesel engine “12V150” and a truck diesel engine “D6114” using the AVIEIT system have been performed. Simulation results show that the in-cylinder charge air amount of the diesel engine with the AVIEIT system is increased at low speed high torque operating conditions, and the fuel economy is improved at high speed operating conditions. In order to test the idea of the AVIEIT system, an experiment on a truck diesel engine “D6114” equipped with an AVIEIT control mechanism has been finished. The experiment results show that the AVIEIT system can improve economy of high speed operating conditions. Both the simulation and experiment results suggest that the AVIEIT system has the potential to replace the Waste-Gate and VGT turbo-charging systems.
