Vector With Turbo Diesel
Technology

Greater Power For Future Needs

Export Power

Fleets requesting power provided by Vector generator to be used for value-added, (non-refrigeration) functions

Natural Refrigerants

Low Global Warming Potential (GWP) refrigerants such as Carbon Dioxide (CO2) operate at higher pressures, requiring more power

Higher Capacity

Fleets pushing for longer, lighter weight trailers (i.e. less well-insulated) to improve freight efficiency

Higher Performance

In “intensive use” applications using auto start/stop, systems with higher performance will better control temperature while also reducing run time, emissions and overall costs

Engine Detail

  • Kohler Engine
  • 1.9 liter
  • 3-cylinder
  • Turbocharged
  • Up to 56 horsepower (42kW)
  • High pressure common rail
  • Diesel oxidation catalyst
  • Exhaust gas recirculation
  • Geared timing
  • CAN BUS electronic controls

Turbo Benefits

  • More power
  • Smaller displacement
  • Better fuel efficiency
  • More complete combustion (i.e., lower emissions)
  • Greater than 25 horsepower Tier 4 Final compliant (i.e., indefinite use in California)
  • ~5 year development & testing
  • ~100,000 hours field operation

Advanced Technology Engine

  • Hot exhaust gas passes from exhaust manifold into cylinder head to be partially cooled by engine coolant
  • If EGR is needed, EGR valve opens and allows EGR into cooler, then into engine
  • No maintenance to EGR cooler due to EGR valve being placed before the cooler
  • Hot exhaust gas passes from exhaust manifold into EGR cooler
  • EGR valve opens when EGR is needed, allowing cooled EGR into the engine
  • EGR cooler fouls over time (clean every 3,000 hours) due to EGR valve being placed after EGR cooler (allows exhaust cool in EGR even when not needed in engine)
