The main source of energy for the propulsion of automotive and trucks is still internal combustion piston engines. These are constantly improved in such a way as to achieve the lowest possible consumption of low-emission fuel. The results of the simulation of new technologies are confirmed in experimental stands, thus being the basis for the develo...

A model of the normal-force dependant friction loss between the rotor and pendula is developed for bifilar centrifugal pendulum vibration absorbers (CPVAs). The normal-force is dominantly dependant on the rotor rotational velocity but also dependant on the pendulum path. Simulation results of the pendulum with the proposed normal-force friction mod...

The transport sector is the second leading emitter of greenhouse gas emissions (GHGEs) from fuel combustion activities on a global scale. Reducing emissions related to this sector requires detailed data about the emissions by vehicle type and traveled distance. Generally, these data are missing in developing countries, which makes difficult the est...

Ambitious long-term greenhouse gas (GHG) emission targets require decarbonisation of the transport sector. Where plentiful supplies of low carbon electricity are available for road transport, passenger cars with internal combustion engines need to be replaced by electric vehicles. However, despite its growing share of transport's CO 2 emissions, no...

This briefing identifies and evaluates government policies aiming to accelerate the transition to zero-emission vehicles (ZEVs). After an examination of policies in the leading ZEV markets, the paper draws implications for future action based on technology, market, and policy trends. The paper is in two parts. Part I, covering light-duty vehicles...

In this study, performance and emission values were obtained under full load by using ethanol-gasoline blends as fuel at different rates in a spark-ignition engine, and exergy, exergoeconomic and environmental analyses were performed with these values. Exergy of fuel entering engine and lost exergies through cooling system, exhaust and radiation were calculated. CO, CO2, HC, and NOX emissions released from engine into environment were measured, and according to environmental analysis, cost of CO2 emission was calculated as 393.78 USD/year for E0 fuel and as 306.78 USD/year for E30 fuel at 2000 rpm. Ethanol-gasoline blends at different rates, environmental damage can be reduced by around 30% on an annual basis. Furthermore, with environmental analysis, lowest engine output power cost was found to be 29.77 USD/MJ in E0 fuel at 2000 rpm, while highest engine output power cost was found to be 120 USD/MJ in E30 fuel at 4500 rpm.
