F1-engines


The engine is the heart of every car, but while the human heart pushes blood into other body parts, primarily for the engine with air. An unwritten rule says that the overall performance of the car, not counting the driver, the engine responsible for approximately 15% to 50% of the chassis and tires for the remaining 35%.
Today's engines in Formula 1 are made from very advanced materials. Even 63% of its parts from aluminum, including the cylinder head, casing shank shafts, pistons, and some parts such as casing pumps for water. Steel is represented in nearly 30% of the crankshaft and camshaft
Titan is a very lightweight material, but very expensive and is used in approximately 5% of cases. Magnesium is also very lightweight material, used for various enclosure

Current rules limit the engine to the 2.4-liter, number of cylinders to eight, prohibits the prednabijanje and all kinds of exotic types of fuel (so that the cars actually use fuel similar to those from petrol stations.
The new rules of volume is reduced, and the number of cylinders, but the power is still impressive - about 750 horsepower 2.4 liter V8 developing the drive unit, and the FIA in 2007. froze their further development, and in late 2007. confirmed that this policy is in effect the next ten years.
One of the most powerful engine in the history of Formula 1 was BMW's 1.5-liter turbo that dominated the eighties of the last century


There are four V-angle isprobavana last year: 72 °, 80 °, 90 ° and 111 °. Narrower engine allows for easier packaging space within the motor and chassis designers more freedom, but the focus becomes more. Wider engine provides a lower center of gravity, but the Renault with its 111 ° V10 had a problem with packaging and high vibration. Cosworth has had the same problems in their experiment with wide-angle engine.


Width Renault V10 engine with a V angle of 111 ° is clearly visible, just as the extremely low altitude, which provides a low center of gravity. Compared with his successor in the picture below, which has a V-angle of 72 °

3.5 liter Formula late 1994th Ferrari had the strongest engine with approximately 800 horsepower, but the Renault with its V10 was very close with 780, while the similar Peugeot and Mercedes engines have around 770th Ford Zetec R in winning Bennetonu Michael Schumacher has evolved from 735 to 740 horses, which indicates that power is not everything.

For comparison, the closest competitor to Ferrari or their Tipo 048, with a V-angle of 80 ° angle, was developing around 775 horses and weighed 112 pounds. When BMW re-entered Formula 1 as a supplier of engines for the Williams team, the standards were raised again. BMW is already in the second season had the strongest engine and it had the next two years. Their P83 from 2003. was the most powerful 920 horsepower Formula 1, and spinning at 19 200 rpm.
