Abstract

The new concept as for the running of engines is to consist, in the motor machine from energy accumulator of energy supply. Charging the energy accumulator is made of an energy generator, which running in a single regime (monoregime) with maximum efficiency. The concept involves the development of engines, generally consist of: energy generator, energy accumulator and motor machine, in which two energy transformation occur, the primary transformation and the secondary transformation. The primary transformation is realized by the energy generator, which transforms the input energy (thermal energy) to another form of energy (fluid energy). The energy produced by the generator is stored in the energy accumulator. The secondary transformation is realized by the motor machine, which takes over the energy stored in the accumulator and transforms it in mechanical energy, usually under the form of a rotation movement. The engine running efficiently if the energy generator, fulfils the following conditions: to produce a form of energy that can be easily stored in the energy accumulator and can be easily transmitted to the motor machine; to running in a single regime, automatic on the principle start-stop, characterized by starting automatically, when the energy in the accumulator has the minimum admitted value, and stopping automatically, when the energy in the accumulator has the maximum admitted value. The energy forms which fulfil the above mentioned conditions are: the hydrostatic energy; and the pneumatic energy. The monoregime engines belong to the category of hybrid termohidraulic. They represent an absolute novelty. At the new engines to produce two energy transformations: thermic energy is transformed into a hydrostatic or pneumatic energy (through the energy generator); the hydrostatic or pneumatic energy is transformed into mechanic energy (through hydraulic or pneumatic engines). The monoregime engines characterized by the following specific features: running in a single regime (monoregime); without moment’s idle running. We estimate the following advantages (compared to the nowadays drive systems by internal combustion engines): less fuel consumption, reduced pollution (it is much easier to optimize a single regime, compared to infinity, as to produce the current engines); simple construction; and good viability. Also, the monoregime engine can to assume, total or part, the transmission functions (control torque, speed and direction of rotation), including the function of braking with the recuperation energy. The new concept as for the running of engines in a single regime (monoregime engines), represents a new research direction, obviously, is much easier to optimize a single regime, compared to an infinity, as to produce the current engines.
