Refer … WebIn-cylinder pressure evaluation In order to get the cylinder pressure trace vs. crank angle, the raw signal for the in-cylinder pressure is evaluated and processed by the ICC part of the WECS-9520. From this data, the compression and firing pressures are determined with polynomical formulas in the software, as illustrated in Figure 5.
WebMar 20, 2024 · where n is a polytropic exponent, P is in-cylinder pressure, V is cylinder volume, and θ is crank angle position. The polytropic exponent has the same value independent of crank angle when the crank angle is correctly calibrated, and assuming constant specific heat capacity and no heat transfer. WebThe correct timing advance for a given engine speed will allow for maximum cylinder pressure to be achieved at the correct crankshaft angular position. When setting the timing for an automobile engine, the factory timing setting can usually be found on a sticker in the engine bay.
