motus

Motus is a collection of procedures that can be used within a Delphi program, which allows you to study floors kinematic systems. Motus uses the Mekin2d library, which is a library born for old versions of Pascal. On the contrary, Motus, it is compilated to an environment of the Delphi. From Mekin2D he inherits part of the calculation procedures, while all the graphic procedures have been rewritten from scratch. I also added the management of motion laws and the calculation of the flat cams.

Calculation of Cam Cinematics

Throughout my professional life I’ve had to write several programs to aid me in calculating cam cinematics. The following images show examples of an aspiration cam for a 4-stroke engine.

Calculation of Cam Cinematics

This software calculates the torque and power curves of a 4-stroke engine given the dimensions and specifications of its components. The program also calculates the cams’ law of motion.
The curves of torque and power are obtained by applying the laws of thermodynamics to the aspiration and exhaust conduits as well as to the cylinder where the combustion process is simulated.
Observing the pressure curve inside the conduits it is possible to deduce the *portate istantanee* in the valve section and therefore the instantaneous torque of the engine. The model also takes into account the chemical composition of the gas in every section of the conduit and the cylinder
