“…They are characterized by favourable mechanical parameters, they have smaller mass than steel and cast iron, and their impact strength does not decrease with lowering the temperature. Moreover, they have good thermal conductivity, low thermal expansion, low friction coefficient and high resistance to corrosion and operational wear [9,10,13].…”

The subject of the investigations are cast pistons used in air compressors. The goal of this work was characterization of the wear of pistons made by aluminium-silicon alloys and showed differences in material characterisation for different aluminium-silicon alloy. A few kinds of pistons were chosen for investigationspistons made by an aluminium-silicon alloy AK12 and AK7. The scope of the work included the observation of pistons using light microscopy and scanning electron microscopy with X-ray microanalysis of chemical composition (EDS -energy dispersion spectrometer). Next the measurements of hardness were carrying out with the Vickers method. The research shows that the wear resistance increases depending on the amount of silicon. Microscopic examinations confirmed the presence of chemical elements which are part of the castings of AK12 and AK7 alloys.

This article concerns the method of material consumption assessment of the cylinder-piston group of diesel engines in the biodiesel environment. The obtained experimental dependences of the wear coefficients on the example of the tribounit cylinder liner and the piston ring can be used to forecast the resource use during operation under specific conditions of the engine and the environment as a whole. The article systematizes the types of biofuels, depending on the type of raw materials from which they were made, taking into account the process and application. The physical and chemical aspects of the catalysts used for biofuels were indicated. The applied experimental methods for tribological wear of the piston-cylinder pair were analyzed. B70 biodiesel was used in the research, i.e., 70% mineral diesel oil and 30% methyl esters of rapeseed oil. Experimental tribotechnical studies of the influence of biofuels on the behavior of various materials have shown that when using this type of fuel, it is necessary to replace the materials from which some parts of the cylinder-piston group are made. To solve this problem, research has been carried out on a specially designed friction machine. The novelty in the article concerns the association, based on the literature, of hydrogen consumption causing material wear in friction contacts. The mechanism of the interaction of various construction materials during such friction has been disclosed.

“…Gerakan sekunder piston [12,13] dan perpindahan panas inilah yang menyebabkan keausan pada pin piston [14], dan berdampak negatif terhadap pin, sehingga sulit dikeluarkan dari rumah piston. Keausan pin piston juga diakibatkan adanya konstur dari dinding silinder yang berubah [15,16], baik itu mengalami deformasi maupun transformasi perubahan bentuk akibat beda potensial suhu [17], yang dihasilkan dari pergerakan piston yang bergerak dari Titik Mati Atas (TMA) ke Titik Mati Bawah (TMB) atau sebaliknya [18]. Faktor usia pin maupun piston juga berpengaruh signifikan [19], terhadap sulitnya pin piston dikeluarkan dari rumah piston.…”

Jigs and fixture merupakan alat perkakas bantu yang berfungsi untuk memegang dan atau mengarahkan benda kerja sehingga proses manufaktur suatu produk dapat lebih efisien. Dalam proses melepas pin dari rumah piston, masih terdapat industri otomotif mikro yang melepas pin piston secara manual, dengan cara memukul pin piston menggunakan palu. Hal ini, mengakibatkan kerugian waktu dan kecelakaan kerja yang tinggi terhadap pekerja. Paper ini, bertujuan untuk meminimalisir kerugian waktu dan melakukan simulasi uji tekan pada jigs pin piston. Penerapan metode simulasi digunakan dalam menentukan kekuatan material dan metode empiris untuk menentukan tingkat efisiensi waktu. Jigs pin piston diperuntukan untuk melepaskan pin Ø 13 mm dari rumah piston dan jenis material jigs piston yang digunakan adalah Aluminum 5052 H32. Simulasi uji tekan dilakukan pada tekanan 0,32 N, 0,44 N, 0,55 N, 0,72 N dan 0,86 N, hasil simulasi dengan pemberian tekanan 0,86 N memberikan Safety Factor 1,90 Kgf dengan kategori aman. Hasil perhitungan secara empiris efisiensi waktu penggunaan jigs piston sebesar 59.49% dan estimasi peningkatan produktivitas sebesar 83.59%, maka dapat dinyatakan layak untuk digunakan.
