Abstract. In this paper we show how the implicit filtering algorithm can be parallelized and applied to problems in parameter identification and optimization in automotive valve train design. We extend our previous work by using a more refined model of the valve train and exploiting parallelism in a new way. We apply the parameter identification results to obtain optimal profiles for camshaft l...

The research conducted in this paper is related to the Effect of Camshaft Racing on Motor Matic Performance. For Performance Testing such as power, torque, engine speed, acceleration at speed 6000 9000 rpm. testing using a dyno test tool type Super Dyno 50L. results are used compare performance an automatic motorcycle standard camshaft (STD) and (BRT). From study it was found that for (BRT) inc...

Free-piston diesel engines are characterized by freely moving pistons without any crankshaft or camshaft connected to the pistons. This allows a compact and efficient engine design, but requires automatic control of the piston motion. This paper present a dynamic mathematical model of a free-piston diesel engine, and a control oriented dynamic analysis leading to a piston motion control structu...

Arbomex S.A. de C. V. is one of the largest worldwide manufacturers ductile cast iron camshafts, produced by means phenolic urethane no-bake sand mold casting method and cold box stack molding technology. As a result development high-strength ADIs, low alloyed with vanadium, for camshaft manufacturing, previous results were published on as-cast process austempering heat treatments applied to ca...

In the present study, ductile iron camshafts low alloyed with 0.2 and 0.3 wt % vanadium were produced to study microstructural mechanical evaluation of lobes camshaft. For this purpose, in one largest manufacturers camshaft México by phenolic urethane no-bake sand mold casting method. The microstructure was studied three zones located at top, middle, bottom optical microscopy, tests performed o...

Free-piston diesel engines are characterized by freely moving pistons without any rigid crankshaft or camshaft connected to the pistons. This allows a highly compact and e cient engine design, but requires automatic control of the piston motion. This paper present a dynamic mathematical model of a free-piston diesel engine, a control oriented dynamic analysis, and a novel computer-based piston ...
