Compression ratio is one of the most important design parameters of compression-ignition engines, directly affecting the combustion process, engine performance, fuel consumption, and emissions. In this study, the effect of compression ratio on the performance of a single-cylinder Ruston & Hornsby 1YWA diesel engine was investigated using the GT-SUITE software. First, a one-dimensional engine...

Naturally aspirated engines provide adequate performance in urban and highway driving conditions where high power and acceleration are not required. However, when greater acceleration and power are needed, mechanical supercharging can be used to increase engine torque and power. This study investigates the effects of mechanical supercharging on a four-cylinder engine. First, the engine was...

Valve springs are critical components of internal combustion engines that are subjected to cyclic loading during engine operation. Therefore, investigating their mechanical behavior is of considerable importance. In this study, the static behavior of the K4M engine valve spring was investigated using the finite element method (FEM). First, the geometry and dimensions of the actual spring were...

Urban rail systems stand out as strategic infrastructures for urban mobility, since, depending on their implementation, they promote accessibility, improve quality of life and reduce environmental impacts, with emphasis on mitigating vehicular traffic and atmospheric pollution resulting from the use of fossil fuels. faced with the need to decarbonize the transportation sector, the...

The purpose of this article is to analyze the recent rise of China and South Korea as global leaders in the production and export of electric vehicles by examining the industrial policies these nations have implemented in the sector. This definition of electric vehicles includes all vehicles (passenger cars, buses, trucks, utility vehicles, etc.) and propulsion types that are not exclusively...
