ACTION AS A CRITERION OF THE CAR OPERATING EFFECTIVENES

Summary. Currently used criteria for determining car operating efficiency in road traffic are, among others, emission of harmful substances, consumption of engine driving fuels, technical service and reliability of operation, safety of use. The operational characteristics of the car in terms of engine driving fuel consumption data is usually recognised as so-called road specific fuel consumption. An important deficiency of this approach is the failure to take into

A STUDY OF THE FUEL CONSUMPTION OF HYBRID CAR TOYOTA YARIS

1. INTRODUCTION One of the main sources of environmental pollution are vehicles [1, 2, 11, 17]. Over the last years, the alternative vehicle propulsion systems have become the main priority for a lot of automotive companies and research teams. The basic objective of those propulsions [4, 6, 7, 11, 15] is the achievement of energy independence from nonrenewable sources like liquid and gas fuels. One of the variants of vehicle propulsion, which is built in a few car models, is a hybrid system [6

ANALYTICAL RESEARCH ON THE GRIP VARIATION OF TWO-AXLE CAR

Summary. This paper presents a theoretical investigation on the decrease in grip coefficient of a car due to the car mass changes for three different running conditions- straightforward, motion in curve and braking. The grip of two types of cars - with forward and rear traction, equipped with three models of tires are studied. The results show a significant decrease of the grip coefficient in longitudinal and lateral directions.
