A model of a flat triple pendulum with obstacles imposed on its position is used for the modelling of a piston-connecting rod-crankshaft system of a mono-cylinder four-stroke combustion engine. The introduced selfexcited system can be only treated as the first step in more advanced modelling of real processes, but some examples of numerical simulations exhibit well known six stages of the pisto...

The Stirling cycle and related terminology is defined. Selected contemporary research involving the cycle in environmentally friendly applications is cited. Three conventional engine configurations that utilize a reciprocating power piston and crank shaft (the Alpha, Beta, and Gamma) are characterized, in terms of minimum number of components, advantages, and disadvantages. A new type of Stirli...

The widespread use of biodiesel in internal combustion engines promotes frequent lubricant drain intervals which in turn affects lubricant sustainability and engine performance. In this research two endurance tests were carried out to evaluate the novel approach of strong base oil filter with palm biodiesel (PME) fueled single-cylinder diesel engine. The effects of strong base filter on lubrica...

Portable powered devices such as construction tools and orthotics require a power supply that is light and compact. Hydrocarbon fuel has exceptionally high energy density compared to batteries but must be converted to mechanical power to be useful. We designed, constructed and evaluated a tiny internal combustion air compressor that uses a free-piston configuration combined with homogeneous cha...

The automobile engine connecting rod is a high volume production, critical component. It connects reciprocating piston to rotating crankshaft, transmitting the thrust of the piston to the crankshaft. Every vehicle that uses an internal combustion engine requires at least one connecting rod depending upon the number of cylinders in the engine. As the purpose of the connecting rod is to transfer ...
