Engines from theToyota Dynamic Force family feature high-speed combustion technologies and variable control systems. They achieve greater thermal efficiencies up to 41% resulting in a high output, due to a reduction in energy loss associated with exhaust and cooling systems, the movement of mechanical parts, and other aspects.[1] The engines have been introduced with the Toyota New Global Architecture (TNGA) platforms.[2]
Common Key Technologies
- High speed combustion technologies:
- Long stroke (Stroke/Bore≒1.2)
- Wider angle between the intake and exhaust valve
- High efficiency intake port with Laser cladded valve seat
- High Compression Ratio up to 14:1
- High energy ignition coil
- New D-4S
- Multi-hole direct injector
- Variable cooling system
- Motor driven water pump
- Heated Thermostat
- Continuous variable-capacity oil pump
- Low viscosity engine oil
- Water jacket spacer
- Piston with Laser Pit Skirt
- Drilled passage between cylinder bores
- VVT-iE
- Small-concave-profile camshaft
- Compact HLA
- High strength connecting rod
- High response intake air control
- Fuel injection control (Multi-injection)
- Cylinder heads with built-in EGR cooler function
- New catalyst
- Exhaust manifold layout change
- Piston oil jet control
