Internal combustion engines are thermal engines that convert thermal
energy into mechanical work. It is achieved as a result of thermal
processes occurring inside a mechanical configuration.
Present-day engines used in cars, trucks, buses, heavy machinery,
ships, vessels, generators etc. mainly utilize Otto, Diesel or Sabathe
thermal processes. Even in theory these processes have outstanding
thermal losses. Mechanical configurations of engines result in additional
energy losses (both in reciprocating piston and Wankel rotary configuration),
so in effect, engines utilize only approximately 35% of energy contained
in the fuel.
As an illustration, only 3.5 dcl out of every liter of fuel is being
converted into mechanical work. At the same time, remaining 6.5
dcl of potential energy is being converted into heat and rejected
into the environment.
Besides a HUGE THERMAL (energy) LOSS, this significantly WARMS THE
ENVIRONMENT.
Engines based on fuel cell technology are currently still in development
and are at the moment only capable of providing enough energy for
basic movement of vehicles. When finished, they should be able to
utilize 50% of energy contained in the fuel, while the remaining
50% will be lost, thus making it unusable for gaining useful work.
The problem of poor utilization of energy in internal combustion
engines has been solved by the inventor's fundamentally new approach
to process governing and heat management in rotary engine design.
In doing so, the inventor has established a NEW THERMAL PROCESS.
As it is customary to name a thermal process by inventor's last
name, this process was titled 'Krajnovic thermal process'.
This newly established - patented - concept of rotary engine operation
is based on TWO thermal processes occurring in the same mechanical
system. This enables significantly greater conversion of heat into
mechanical work, i.e. substantially greater utilization of energy
contained in the fuel.
In such an engine, the following processes take place SIMULTANEOUSLY:
