Formel 1-motorer

Fra Wikipedia, den frie encyklopedi
Alfa Romeo 159 rekkeåtter med 317 kilowatt, brukt i racing etter Formula 1-regler fra 1946 til 1951

Denne artikkelen gir en oversikt over Formel 1-motorer, også kalt Formula 1-aggregater (engelsk: power units) siden 2014 da den bensin-elektriske hybridæraen startet.

Motorformlene har variert for de ulike tidsperiodene for sporten.[1][2][3] Helt siden starten i 1947 har Formel 1 brukt en rekke reguleringer for motorer. Før det igjen siden etter første verdenskrig (c. 1918) har mye av Grand Prix-racing generelt med jevne mellomrom hatt ulike "formler" som har begrenset motorkapasiteten.[trenger referanse]

  1. ^ 2-stroke, gas turbine, rotary, etc.
  2. ^ MGU (Motor Generator Unit)-Kinetic (brake) and MGU-Heat (exhaust) energy recovery systems allowed.
  3. ^ Displacement must be between 1,590cc and 1,600cc. Naturally aspirated engines are not prohibited. Boost pressure is not limited.
  4. ^ Lower rpm fuel flow restriction on the next column reaches the maximum of 100kg/hour at 10,500rpm. At this flow rate, further increasing rpm requires lower boost, or results in thinner air/fuel ratio. Due to this, engine manufacturers normally set the maximum engine speed at about 13,000 rpm.
  5. ^ Maximum fuel flow rate (Q) is limited in relation to engine speed below 10,500rpm. On or above 10,500rpm, the maximum fuel flow rate of 100kg/hour applies.
  6. ^ 10% ethanol content is required in pump gasoline.
  7. ^ Smaller displacement is allowed. Naturally aspirated engines are not prohibited, but were not used by any team. Boost pressure is not limited, but fuel flow rate (which was not regulated up to 2013) is limited to 100 kg per hour Mal:Citation needed span
  8. ^ 5.75% bio-sourced alcohol content is required in pump petroleum.
  9. ^ Kinetic (braking) energy recovery system (KERS) allowed.
  10. ^ For 2006 and 2007, the FIA reserved the right to give special dispensations to teams without access to new specification engines to use 2005-spec engines with a rev-limiter. This dispensation was given to Scuderia Toro Rosso only in 2006.
  11. ^ For 1952 and 1953, World Championship races were run to Formula Two rules (0.75 L with compressor, 2 L without), but Formula One regulations remained intact.
