Abstract:

A 1.0 liter 3-cylinder turbocharged gasoline direct injection (TGDI) engine was designed and developed by Dongfeng Motor Corporation. In design and development, computational fluid dynamics (CFD) simulation, port flow test, transparent engine investigation and a series of advanced technologies were used
to optimize the combustion system to improve the comprehensive performances. An efficient and low inertia turbocharger was selected, to ensure performance output and transient responsiveness. Effective technical measures including friction reducing, thermal management, variable oil pump and dual variable valve timing (DVVT) were applied to achieve the good fuel economy. Engine structure design, mass balancing strategy and mounting system optimization were made to achieve excellent noise vibration and harshness (NVH) performance. Bench tests and vehicle carrying tests were done. The results show that benefited from the modular design concept, the engine size is minimized with the advantages for packaging, especially for hybrid vehicles, therefore meeting the design goals of the engine performances.
