The output of a piston engine is measured in brake horsepower. To find brake horsepower, you take the brake mean effective pressure(BMEP) times the displacement times the engine speed and divide it by 792, 000... The BMEP is not the actual pressure within the cylinder, but an effective pressure representing the mean gas load acting on the piston during the power stroke. As such, BMEP is a convenient index for a majority of items of reciprocating engine output, efficiency and operating limitations. 3, record 14, English, - brake%20mean%20effective%20pressure

On emplit le récipient par une quantité de produit mesurée au préalable. Le cycle de fonctionnement comprend une phase d'aspiration et une phase de refoulement. Pendant l'aspiration, le piston monte et prélève une quantité de produit dans le réservoir grâce à une vanne à boisseau tournant et transfert le produit dans le cylindre de mesure calibré. Lorsque le cylindre est rempli la vanne à boisseau tournant obture la liaison avec le réservoir et met en relation le cylindre avec le récipient à remplir. Le piston refoule alors le produit dans le récipient. 1, record 16, French, - dosage%20et%20remplissage%20volum%C3%A9trique%20par%20piston
