RAY: So you probably need a crank angle sensor and a catalytic converter, Bob.
In Figure 5, the total mass of oil in the cylinder is presented as a function of crank angle.
In contrast, an instrument can be used to measure the actual pressure in the compressor cylinder as a function of crank angle.
For the closed cycle period, Watson recommended the following engine calculation crank angle steps: 10[degrees]CA before ignition, 1[degrees]CA at fuel injection timing, 2[degrees]CA between ignition and combustion end, and finally 10[degrees]CA for expansion.
A p-V diagram can be drawn by substituting the crank angle with the volume of the compression chamber.
The simulation has taken into account the nonlinear stiffness of rubber elements, the variation of electric motor torque regarding the instantaneous rotation speed, the variations of the crank mechanism momentum of inertia as the function of the crank angle and instantaneous compressor torque calculated with a compressor model (Pavkovi', 2001, 2002), as the function of the in-cylinder processes (without the use of perturbation harmonics).

The combustion characteristics of the engine were studied in terms of cylinder pressure and rate of pressure rise with respect to crank angle.
Cam phasing is the shifting of the valve events in the crank angle (or cam angle) domain.
The MPC5500 allows implementation of more precise control for timing based upon time or crank angle of the engine application, by utilizing the eTPU independent of the main microprocessor.
