Abstract
This paper presents an algorithm for setting the dynamic parameters of the classic main mechanism of the internal combustion engines. One presents the dynamic, original, machine motion equations. The equation of motion of the machine that generates angular speed of the shaft (which varies with position and rotation speed) is deduced by conservation kinetic energy of the machine. An additional variation of angular speed is added by multiplying by the coefficient dynamic (generated by the forces out of mechanism). Kinetic energy conservation shows angular speed variation (from the main shaft) with inertial masses, while the dynamic coefficient introduces the variation of ω with forces acting in the mechanism. Deriving the first equation of motion of the machine it obtains the second equation of motion dynamics. From the second equation of motion of the machine one determines the angular acceleration of the motor shaft. It shows the distribution of the forces (on the main mechanism of the engine) to the internal combustion heat engines. Dynamic, the velocities can be distributed in the same way as forces. Practically, in the dynamic regimes, the velocities have the same timing as the forces. The method is applied separately for two distinct situations: When the engine is working on a compressor and into the motor system. For the two separate cases, two independent formulas are obtained for the engine dynamic cinematic (forces speeds). Calculations should be made for an engine with a single cylinder.
Highlights
In full energy crisis since 1970 until today, production and sale of cars equipped with internal combustion heat engines has skyrocketed, from some millions yearly to over sixty millions yearly and the world fleet started from tens of millions reached today the billion
An additional variation of angular speed is added by multiplying by the coefficient dynamic
One can see the engine main mechanism in motor system (Petrescu and Petrescu, 2005; 2009a; 2009b; 2013a; 2013b; Petrescu et al, 2005; Petrescu and Petrescu, 2014; 2013c; 2013d; 2011; Petrescu, 2012a; 2012b)
Summary
In conditions which started to magnetic motors, oil fuel is decreasing, energy which was obtained by burning oil is replaced with nuclear energy, hydropower, solar energy, wind and other types of unconventional energy, in the conditions in which electric motors have been instead of internal combustion in public transport, but more recently they have entered in the cars world (Honda has produced a vehicle that uses a compact electric motor and electricity consumed by the battery is restored by a system that uses an electric generator with hydrogen combustion in cells, so we have a car that burns hydrogen, but has an electric motor), which is the role and prospects which have internal combustion engines type Otto, Diesel or Wankel (Amoresano et al, 2013; Dawson, 2005; De Falco et al, 2013a; 2013b; Dieter, 2000; Eneşca, 2007; Ferguson and Kirkpatrick, 2001; Ganapathi and Robinson, 2013; Gunston, 1999; Gupta, 2006; Guzzella, 2004; Heywood, 1988; Karikalan et al, 2013; Lee, 2005; Liu, 1995; Mahalingam and Ramesh Bapu, 2013; Naima and Liazid, 2013; Narasiman et al, 2013; Petrescu and Petrescu, 2005; 2009a; 2009b; 2013a; 2013b; Petrescu et al, 2005; Petrescu and Petrescu, 2014; 2013c; 2013d; 2011; Petrescu, 2012a; 2012b; Piltan et al, 2012; Rahmani et al, 2013; Ravi and Subramanian, 2013; Ronney et al, 1994; Sapate and Tikekar, 2013; Sethusundaram et al, 2013; Zahari et al, 2013; Zhu et al, 2007)?. ⋅D where, the dynamic coefficient D takes the values of the system (4) or (5); (4) when the engine works in compressor system and (5) when the mechanism works in motor system: One keeps just the final relations (7): Dc sin2ψ
