Testing Energy Consumption in the Trolleybus and the Bus on a Chosen Public Transport Line in Lublin

The paper deals with coasting as an option of using the vehicle kinetic energy. It highlights the need for changes in the legislation in conjunction with the use of new trends in the management of motor vehicles with regard to safety. The article describes the use of the vehicle is coasting as a part of the driving mode, which leads to the reduction in fuel consumption and in exhaust emission. This solution takes into account all the running resistances and creates a basis for designing appropriate control strategies. These options were analyzed with respect to various drive strategies and kinds of transport.

“…The precise train diagrams (prescribed speed, stops for passengers, etc.) and low rolling resistance are beneficial at using of coasting in the rail transport [23,7].…”

“…The advantage of the hybrid city bus versus conventional bus is the possibility of recovery of energy when move downhill and braking. The number of intersections where the vehicle has to stop directly impacts the energy consumption [10]. It can be affected by the green waves at traffic lights to ensure the free flow of traffic.…”

Electric or hybrid vehicles are becoming increasingly common on roads. While electric vehicles are still more or less intended for city traffic, hybrid vehicles allow normal use due to wider driving range. The use of internal combustion engines in hybrid drives is still an inspiration to find the way to reduce the production of emissions. Numbers of alternative energy resources were studied as a substitution of conventional fuels for hybrid vehicles drives worldwide. The paper deals with the possibility of using alternative fuels as CNG, LPG and LNG in combination with hybrid drive of a midibus with the capacity of 20 passengers. Various aspects and techniques of hybrid vehicles from energy management system, propulsion system and using of various alternative fuels are explored in this paper. Other related fields of hybrid vehicles such as changes of vehicle weight or influence of electric energy sources on the total vehicle emission production are also included.

“…In the case of electric vehicles, energy intensity of traffic constitutes smaller part of the consumed energy than in the case of combustion vehicles [12,13]. The vast majority of the losses generated by the combustion propulsion system refers to energy loss.…”

Continuous energy intensity is a relationship between continuous energy intensity and energy intensity of movement. In the paper we proposed to analyze energy intensity of the movement, as the size specifying the power demand to the wheel drive and presented the balance of power of an electric car moving in the urban cycle. The object of the test was a hybrid vehicle with an internal combustion engine and electric motor. The measurements were carried out for 4 speeds and 2 driving profiles.
