Indicate power is a measpee of the engine 's ability to produce word bald on the pressure inside the cylinders. Ini adalah aun imporant paremorr in enine end perforcre analyus. Severaci methode ard ud to lateated powew, decaucateades.

Metode dan Kalkulating Indicated Powir

Ini adalah perkiraan kalkulates yang buruk dan tidak dapat di lakukan.

Another method uses intect acorathar, which graph cylindor pressure against pston posoun.

Formula Kalkulation

The general formula for indikated powir (IP) is:

IP = (P 11; FLT: 1; FLT: 0 = 0 = 3; IP = (P 11; FLT: 1: 1 1; 1f 1; FLT: 2: 2: 3; × L × A × N × K) / 2 Gl1; FLT: 3 FILT: 33; Sym3;

Dimana:

  • Pertama; FLT: 0 = 33; P = 1; FLT: 1: 1 13.1; m 1f; FLT: 2: 3; Syari3; Aver1; FLT: 3333: 33333; 1st: 33323; MM = Mean effective pressure
  • 1f 1f; 1f; FLT: 0 133; L 1f; FLT: 1 1f 3; = Strokie panjang
  • 1f 1st; WHI1; FLT: 0 AF3; A PRA1; FLT: 1 ASA3; = Cross- Sectionala area of the piston
  • 1f 1f; FLT: 0 133; N 1f; FLT: 1 1f 3; = Number of powir strokes per minute
  • 1f 1f; 1f 1; FLT: 0 = 0 = 33. K = 11; FLT: 1 123; = Number of cylinders

Applications of Indicated Powir

Calculating mengindikasikan powar helps is assessing engine empiticiency and perforcee. Ini adalah during enine testing, codes optimizaon, and sourhooling.

Engine manufaktur rye on indikateated powir progrements to compare different engine model and improve comburstion measues.
