“…Linia optymalnych obciążeń (linia docelowa) może przebiegać różnie w zależności od przyjętej strategii sterowania hybrydowym układem napędowym. Na rysunku 3 przedstawiono dwie strategie sterowania przyjęte dla dwóch różnych silników spalinowych samochodów Toyota Prius o pojemnościach skokowych 1,5 i 1,8 dm 3 [9].…”

Modern vehicles with hybrid combustion-electric drive systems are an important element in the strategy for reducing fuel consumption and emissions of exhaust gas components. Determinant of the use and development is to achieve substantial benefits in terms of classical powertrain vehicles equipped with internal combustion engines. This paper presents the concept of kinematic ratio selection between the engine and the electric machine. This concept is based on the analysis of the internal combustion engine load caused by the resistances of motion and the best possible assessment of the additional load caused by the operation of the generator. It is proposed that the energy transferred to the generator was taken in a most preferred area of the engine performance characteristics and generator by changing kinematic ratio between the engine and the generator. The described concept can also be used for the recovery of vehicles braking energy.

Analiza linii pracy silnika spalinowego (a nie charakterystyka zewnętrzna) w warunkach pracy napędu hybrydowego wskazuje, że we wcześniejszej wersji silnik 1NZ-FXE pracował w zakresie większych ciśnień użytecznych niż w wersji obecnej -2ZR-FXE [14]. Różnica the vehicle, and the electric motor -only the rear axle.…”

Continuous increased interest in hybrid drive systems enabling the reduction of fuel consumption and emissions of harmful substances into the atmosphere, as well as their use partly as zero-emission drive in vehicles provides the basis for the development of these types of drive systems. Such trend is indicated by sales analysis of hybrid drives, and this means that actions taken towards of reduction of fuel consumption are still justified. The article reviews combustion engines for hybrid drive systems as far as determination of their operating conditions, indicating mean effective pressure and power/displacement ratio are considered. The concept of hybridization was defined as a measure of the degree of utilization of vehicle electric drive systems (or its drive support). The analysis was conducted on the basis of vehicles equipped with different hybrid drive systems with combustion engines with spark ignition and compression ignition. The hybridization indexes for different groups of hybrid drive systems were determined and significant discrepancies in the way of their determination were pointed out.
