Analyzing Vehicle Ride Regime for GHG Emission Reduction

Abstract

Environment protection is the one of critical human problems, since its solution depends on people life, their health and welfare. The automotive industry is a major source of greenhouse gas (GHG) emissions, contributing to global climate change. This article provides an overview of the environmental impact of the vehicle and tasks to reduce GHG. 4-step methods of reducing the environmental impact of the vehicle are reflected in the article. Trucks with gross weight of 40 t and different engines are taken as objects of research, which are indicated as objects A, B, C in the following text. The operating modes of the engine in terms of fuel economy and reduction of environmental damage are given in the example of 3 cars. It is stated that when power usage grade is U = 0.8 and engine operates in 70-80% of its maximum engine speed a fuel consumption and environmental damage is reduced. The article summarizes the following: operation of the engine with power usage grade around 0.8 in the city conditions can be provided by using engines with appropriate power i.e. a car with big engine power is not necessary in the city conditions in terms of fuel economy and environment protection.
