"Two-stroke engines are far simpler than four-stroke engines from a physical perspective. For a given brake output, two-stroke engines are lighter, easier to work on, and provide higher power-to-weight ratio than four-stroke engines, making them suitable for small platform applications. However, conventional two-stroke engines have a reputation for generating smoke and unburned fuel, meaning they may not meet many emissions regulations, now enforced around the world. Thus, for many decades two-stroke engines have not been not favored, giving way to four-stroke engines for dominant applications, especially for mobile power-generation purposes. In the quest to improve the potential of such an engine, a group of researchers from the Automotive Development Centre (ADC), Universiti Teknologi Malaysia (UTM), has developed a 125 cc, air-cooled stepped-piston engine to demonstrate the higher power-to-weight ratio feature, apart from overcoming emission reduction. The engine is designed to mitigate the problem of mixture short circuiting, which is the major hindrance to combustion efficiency. To this end, they have incorporated a three-port stratification strategy into the engine. This paper provides an overview related to the earlier work done to integrate the necessary features and highlights some of the performance features of this unique engine design"

"This volume of the Lecture Notes in Mobility series contains papers written by speakers at the 22nd International Forum on Advanced Microsystems for Automotive Applications (AMAA 2018) "Smart Systems for Clean, Safe and Shared Road Vehicles" that was held in Berlin, Germany in September 2018. The authors report about recent breakthroughs in electric and electronic components and systems, driver assistance, vehicle automation and electrification as well as data, clouds and machine learning. Furthermore, innovation aspects and impacts of connected and automated driving are covered. The target audience primarily comprises research experts and practitioners in industry and academia, but the book may also be beneficial for graduate students alike. "

"This volume gives an overview on recent developments for various applications of modern engineering design. Different engineering disciplines such as mechanical, materials, computer and process engineering provide the foundation for the design and development of improved structures, materials and processes. The modern design cycle is characterized by an interaction of different disciplines and a strong shift to computer-based approaches where only a few experiments are performed for verification purposes. A major driver for this development is the increased demand for cost reduction, which is also connected to environmental demands. In the transportation industry (e.g. automotive or aerospace), this is connected with the demand for higher fuel efficiency, which is related to the operational costs and the lower harm for the environment. One way to fulfil such requirements are lighter structures and/or improved processes for energy conversion. Another emerging area is the interaction of classical engineering with the health and medical sector. In this book, many examples of the mentioned design applications are presented."

"Mesin pembakaran dalam yang irit bahan bakar dipengaruhi oleh desain dan material yang digunakan. Semakin ringan bobot dari mesin maka akan semakin ringan pula bobot dari kendaraan sehingga kendaraan tersebut menjadi irit bahan bakar. Desain mesin yang sederhana dan ringan tanpa melupakan fungsinya merupakan landasan terciptanya mesin irit bahan bakar. Cylinder head dan camshaft assembly merupakan salah satu komponen penting yang mempengaruhi kinerja mesin. Berdasarkan hasil perhitungan analitik pada penelitian ini diperoleh dimensi dari tinggi cylinder head (L) sebesar 24 mm, diameter camshaft (d) adalah 6 mm, tinggi(h) dan lebar (b) rocker arm adalah 8,44 mm dan 4,22 mm, dan nilai konstanta pegas (K) berdasarkan rekayasa balik adalah 10300,5 N/m. Selain itu pada penelitian ini dibahas mengenai kekuatan cylinder head, camshaft, rocker arm, dan pegas dengan membandingkan nilai Von Mises stress yang didapat melalui perhitungan analitik dengan perhitungan numerik dengan bantuan software ANSYS 14. Nilai Von Mises stress menggunakan perhitungan analitik pada cylinder head adalah 49,029 MPa, pada camshaft titik C dan titk D adalah 206,63 dan 297,16 MPa, pada rocker arm adalah 21 MPa, dan untuk pegas adalah 451,8 MPa. Sedangkan menggunakan perhitungan numerik pada cylinder head adalah 48,519 MPa, pada camshaft titik C dan D adalah 65,288 dan 406,58 MPa, pada rocker arm adalah 66,078 MPa, dan pada pegas adalah 844,49 MPa. Analisis fatigue digunakan untuk mendapatkan lifetime dari cylinder head adalah 2 tahun, camshaft adalah 4 tahun, rocker arm adalah 1,7 tahun, dan pegas 1 tahun.

Combustion engine in which fuel economy is affected by the design and materials used. The lighter weight of the engine will also be light weight of the vehicle so that the vehicle to be fuel efficient. A simple design and lightweight machines without forgetting its function is the main idea to create fuel efficient engine. Cylinder head and camshaft assembly is one of the important components that affect engine performance. Based on the results of analytical calculations in this research were obtained from a height of cylinder head (L) is 24 mm, diameter of the camshaft (d) is 6 mm, height (h) and width (b) of rocker arm is 8.44 mm and 4.22 mm , and the value of the spring constant (K) based on reverse engineering is 10300.5 N / m. In addition, this study discussed the strength of the cylinder head, camshaft, rocker arm, and spring by comparing the value of Von Mises stress obtained through analytical calculations with numerical calculations with the help of ANSYS software 14. Von Mises stress values using analytic calculations on the cylinder head is 34.29 MPa, the camshaft on points C and D are 206.63 and 297.16 MPa, the rocker arm is 21 MPa, and for spring is 260.85 MPa. While using numerical calculations on the cylinder head is 48.519 MPa, camshaft on point C and D are 65.288 and 406.58 MPa, rocker arm is 66.078 MPa, and the spring is 844.49 MPa. Fatigue analysis is also used in simulation using ANSYS 14 to obtain the lifetime of the cylinder head is 2 years before failure, camshaf is 4 years, rocker arm is 1.7 years, and spring is 1 year."

"ABSTRAKDalam pengoperasian suatu kapal diperlukan suatu sistem yang mengatur tentang perawatandan pemeliharaan bagian-bagian utama pada kapal tersebut. Hal ini diperlukan untukmenghindari terjadinya masalah yang dapat menghambat kerja kapal, seperti breakdown padamesin dan sebagainya. Selain itu sistem pemeliharaan yang dilakukan secara terencana danberkala, juga dapat memperpanjang usia pakai suatu kapal sehingga dapat menambahproduktifitas kapal tersebut. Hal-hal yang berkaitan dengan pemeliharaan pada semuakomponen yang terdapat di suatu kapal, juga telah diatur dalam International SafetyManagement Code (ISM Code). Atas dasar itu maka pembuatan suatu sistem perawatanterencana atau biasa disebut Planned Maintenance System (PMS) pada suatu kapal sangatlahdiperlukan. Dalam hal ini komponen-komponen yang terdapat pada kamar mesin suatu kapalBulk Carrier 13601 DWT akan dijadikan objek penelitian untuk pembuatan sistem perawatantersebut.

ABSTRACTIn the operation of a ship, it is essential to have a system that regulates the maintenance of themain parts of the ship. This is necessary to avoid the problems that can inhibit the shipperformance, such as the breakdown in machinery and so on. Moreover, a maintenancesystem that is done in a well-planned and regular manner can also extend the life of a ship soas to increase the productivity of the ship. Matters related to the maintenance of allcomponents contained in a ship also have been regulated in the International SafetyManagement Code (ISM Code). On that basis, it becomes necessary to arrange a PlannedMaintenance System (PMS) on a ship. In this case the components contained in the engineroom of a 13601 DWT Bulk Carrier ship will be the object of research for the preparation ofthe maintenance system."
