During this exploratory process, the Saint-Hilaire team came to realize that a unique engine solution would be one that made improvements to the standard Wankel, or rotary, engine. The reversibility of a pneumatic system storage worsens with increasing chosen pressure, unless the heat is also stored in the tank at the time of compression storage for short duration and low 10 bar — psi. The Quasiturbine engine, patented in , is just such an improvement. This, of course, is the gasoline engine.

While the piston engine is the most common type found in cars, engnie Quasiturbine engine operates more like a rotary engine. Those result can be scaled linearly for other pressure differentials.
Quasiturbine - Wikipedia
A high pressure tank cooled gradually when pour in an intermediate low pressure tank, but it is at the entry of the low tank pressure that the relaxation is violent and where cooling is most considerable. It is still a concept. This heterogeneous mixture is then compressed, which causes the temperature to rise until self-ignition quasituurbine place.
Usable with intake sustained pressure as low as 20 to 50 psi! Why hasn't there been significant improvement in the quality of fuel used in automotive? To get the most power engnie of a machine not necessarily to get more efficiencyone likes to add heat to the expanding gas, and if this is not possible in entine process, the expansion is split in several stages like 2 and 3 stages steam turbine. Why hasn't the camshaft in a normal four stroke engine been replaced with an electronic or some other system?
One restriction of this usage is that the two fluids must be similar; It would fngine be possible for example to drive an integrated air pump with hydraulic fluid, as the rotor design is significantly different.
How Gas Compression-ignition Engines Work. There's no need for the crankshaft to perform the rotary conversion.
Suitable as a double-circuits Rotary Motor or Expander for compressed air, steam and quasiturbihe fluids, or later as an advanced Internal Combustion Rotary Engine, as well as later for Compressor of various thermodynamic cycles.
It does qussiturbine in heavy smoke or under water as well. The pressure of combustion is contained in a chamber formed by part of the housing on one side and the face of the triangular rotor on the other side.
Do not translate text that appears unreliable entine low-quality. Within the bottles, the energy is strictly that of the adiabatic pressure drop ignoring the potential energy generated by the coldness of the gas, which is recovered due to an external heat contribution!
As an example, a typical bar atm.
This is also the design proposed for use as a pump envine, and particularly as a supercharger. The Quasiturbine at the invention autopsy: This is why QT is efficient less pressure charging lossesand this is why there is no vane combustion engine. In the conventional turbines, one often makes such an intermediary heating in order to increase the total power output of the machine, without necessarily increasing the efficiency.
Enter the Quasiturbine with carriages. Quasiturbine — Comparative efficiency with other engines http: As of [update]which design will be used for further work on the internal combustion version has not been announced.
Why can't we start an engine after water has been added to the tank?
Why don't we ejgine turbine engines in our cars? Black Friday is here. When a spark ignites the fuel, a hot flame sweeps through the mixture, burning the fuel as it goes. In those temperature conditions at the entrance of a pneumatic quasitubrine, the efficiency is catastrophically low and the lubricant solidified, increasing considerably the internal engine friction… Generally, the reversibility of the compression — relaxation cycle reduces with an increase in pressure, which favours for high efficiency consideration the use of the lowest design pressure possible.
Did cars ever have external combustion engines?
How Quasiturbine Engines Work
The Quasiturbine is a positive displacement turbine with a total displacement near the engine volume Imagine one day, a 3 litres car engine into a 3 litres volume! The prototype was turned by an external engine for 40 hours.
To harness the energy of expanding gas in this way, an engine must cycle through a set of events that causes many tiny gas explosions.
Related Questions Why can't we start an engine after water has been added to the tank? It is however not very wise to use the energy of pressure of high pressure tank to heat the intermediate partially low pressure tank, from where the interest to use multiple mechanical relaxations with heaters isobars between the stages!
It does also fit very well the pure thermal sources, like the solar energy thermal conversion stations.
