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
