Abstract

Datsun Go merupakan salah satu mobil Low Cost Gren Car (LCGC) yang beredar di Indonesuia. Mobil ini sudah dilengkapi dengan sistem AVG (Average) atau pembacaan rata-rata bahan bakar yang dapat dilihat dengan mudah pada display. Namun demikian laporan terkait konsumsi bahan bakar yang disampaikan pengguna kendaraan sangat bevariasi. Tujuan studi ini adalah untuk menginvestigasikesalahan pembacaan konsumsi bahan bakar pada berbagai kondisi dan dinamika kendaraan. Metode studi ini dengan mensimulasikan berbagai kemiringan dan juga akselerasi kendaraan. Hasil investigasi menunjukan bahwa terjadi kesalahan pembacaan fuel sender karena pengaruh dinamika kendaraan Dinamika dan kondisi kendaraan sangat berpengaruh terhadap pembacaan konsumsi rerata bahan bakar.

Abstract

This article presents an overview of the technology status and market trends of LPG-fueled vehicles through the literature approach to re-evaluate their future. In the review, it is discovered that LPG vehicles are globally increasing, though with a concentration in some countries. Of the 25 countries included in the World LPG Association (WLPGA) annual report 2018, Turkey, Poland, India, Ukraine, and Mexico are the countries with the best LPG vehicle trends in average of 23%. Meanwhile, Australia, Japan, South Korea, United Kingdom, the Netherlands, France, and Germany with a long history of implementing LPG as an alternative fuel has experienced a decline in the 2013-2017 period by 17%. This was allegedly due to the penetration of diesel-fueled vehicles over the last ten years. Moreover, developed countries experiencing decline have succeeded in developing electric-based vehicles such as Hybrid Electric Vehicle (HEV), Plug-in hybrid electric vehicle (PHEV), Battery Electric Vehicles (BEV), and Fuel Cell Electric Vehicles (FCEV) due to stringent demands for emission standards.

Abstract

It has been a year after the announcement of Covid-19 outbreak in Wuhan. Activity restriction, implementation of health protocol, and lock-down are enforced to cut-off the spread of this virus. However, in the uncertainty towards a new normal, the mobility of people continues for various purposes. A rapid medical check-up at the airport or at railway stations is possible by the local authorities but it is impossible for public bus passengers due to the limitations of medical staff and a large number of bus stations. Most passengers also failed to comply with the government's recommendation to conduct a rapid test before using public buses. As anticipation, the Transportation Agency issued a regulation that all buses can only be filled with 50% (max) of their normal capacity by emptying 2 of the 4 seats in a row. As a consequence, a 32-seat bus can only be filled with 16 passengers (max) and the ticket price has doubled to cover operational costs. However, passenger interest in bus services has decreased due to high ticket prices. Therefore, this short article reports the smart actions of several bus companies in Indonesia to create a "Captain Seat", a 1-1-1 bus seat configuration to ensure physical distancing between passengers. With the captain seat model, buses with 32 seats are modified to 24 seats, the ideal distance between passengers during a pandemic can be maintained, the risk of loss to bus companies can be reduced, and passenger costs can be lowered.

Abstract

In recent years, one of the most logical efforts made to reduce the dependence on fossil energy sources is the use of a gasoline-methanol fuel blend. However, the problem in using a gasoline-methanol blend as fuel is that the methanol will eventually separate itself from the gasoline unless they are properly blended together, this is because methanol has a polar hydroxyl group called monohydric that binds water vapor together, causing the mixture to separate. Previous research showed that adding a small amount of ethanol to the gasoline-methanol blend makes it a homogeneous blend. Therefore, this research aims to identify the exhaust emissions of the homogenous gasoline-methanol-(ethanol) blend. For each blended fraction was tested on a single-cylinder four-stroke engine. The emission test is carried out in two stages which include the gasoline mode, and the alcohol mode. These two measurement modes undergo a validation process to correct the differences in the measurement results of the gasoline-methanol-ethanol blends. The test results show that increasing the methanol fraction in the gasoline-methanol-(ethanol) fuel blend results in reduced emission of carbon monoxide and unburnt hydrocarbon because methanol has a high enthalpy of evaporation, which increases both volumetric efficiency and complete combustion. In addition, the increase in the methanol fraction in the gasoline-methanol-(ethanol) blend showed a higher increase in carbon dioxide emissions. This is because methanol and ethanol have a much lower energy content than gasoline. Therefore, its energy production per unit time requires more fuel molecules.

Abstract

Although the technology of fuel injection in motorcycles has reached ports and direct injection, motorcycles with carburetors are still used. In this research, the carburetor was modified by adding a swirling vane. This study is intended to provide an explanation regarding engine performance which includes torque, power, mileage, emissions, and engine oil temperature. The study begins with a review of the shape and flow characteristics of the swirling vane based on the largest flow according to previous studies. Then, a swirling vane is built and tested to ensure its optimal shape. The findings were compared with conventional carburetor-based engines that had not been treated. Experiments were also carried out on gasoline-ethanol to obtain optimal results and use them appropriately for alternative fuel applications. A comparison of data on torque, power, exhaust emissions, temperature, and mileage reveals that vehicles modified with swirling vanes have better performance. Furthermore, based on the results of gasoline-ethanol application tests, this design is only suitable for use up to E25.
