Mateychyk V. Science bases to increasing of vehicle ecological safety.

The thesis devoted to the problem of increasing the vehicle ecological safety by the way of improvement of fuel consumption and ecological parameters. The general methodology for the estimation of vehicle ecological safety by the criterions efficiency fuel consumption and level of environment pollution with allowance for assigning and operation conditions has been created. The operation model of the system "road vehicle" with usage of system objects has been working out, that allows to estimate the influencing of design and operational factors on vehicle ecological safety. The methodic and mathematical models for definition of efficiency of fuel consumption and level of environment pollution of vehicles with the improved power installations in separate modes, in driving cycles and on operational routes were designed. The complex of separate and integral criterions for an estimation and selection the ways of increasing vehicle ecological safety with taking account their assigning and operation conditions was offered. Estimation the ways of increasing vehicle ecological safety by advancing of power supply and regulation systems for petrol and diesel engines, by conversation of petrol and diesel engines on natural gas and also by replacement the petrol engines by diesel was executed.
