- Summary:
- Toyota Motor Corporation has developed a new 2.0L Inline 4- Cylinder (I4) Gasoline Direct Injection Engine, the second Naturally Aspirated (NA) engine of the Toyota New Global Architecture (TNGA) engine series, to meet our customers' expectations for drivability, performance, and fuel economy. The high speed combustion technologies adopted previously in our 2.5L NA conventional and Hybrid Vehicle (HV) engines for the 2018 Toyota Camry are necessary for high engine power and thermal efficiency. To adopt our high speed combustion technology on engines with different displacements, the turbulence intensity has been defined as the target index of combustion speed. The basic engine structure has been revised by using Computational Fluid Dynamics (CFD) analysis to achieve the combustion target.Additionally the Toyota dual injection system D-4S (Direct injection 4 stroke gasoline engine Superior version) has been improved by our new multi-hole injector design to reduce fuel wetting due to the smaller displacement.With these new technologies, and further optimization, the new 2.0L I4 gasoline direct injection engine achieved top level specific power and thermal efficiency in its class.As a result the new 2.0L Gasoline Direct Injection Engine, in combination with the newly developed Continuously Variable Transmission (CVT), allow our vehicles to achieve top acceleration, vehicle performance, and fuel economy
