Good evening
thank you andre for these figures which are not very encouraging!
improve engine combustion?
is gasoline combustion + the right amount of air not complete?
Is the poor performance of our engines not due to a poor operating principle?
valve valves, -transmission of the piston power by the principle of crankshaft connecting rod which seems to me not famous for the passage of a maximum torque especially at the start and end of the race ....
should we not look to other mechanical principles of the engine?
thing which is not really feasible by me and by the major part of us and appear not by the manufacturer themselves, apart from the rotary engine they fall asleep a little on their laurels the manufacturers !!!!!
100% with water ??
Hello
for whom the engine is 100% water.
let's assume that a hydrogen engine is 100% efficient.
let us assume that the alternator is an efficiency of 100%.
let us assume that electrolysis is a yield of 100%.
(all this is already impossible)
well the motor would be able to self-power but could not undergo any load!

The problem with today's heat engines is due to several things:quick wrote:[...] is the poor performance of our engine not due to a poor operating principle?
- only part (25 to 35%) of the energy from combustion is used to expand the gases, which produces the driving force recovered by the movement of the pistons and then of the crankshaft,
- part of this energy, in the form of heat, heats the walls of the combustion chambers and cylinders, that's why we are forced to cool the engine, in pure loss (except to recover this energy),
- the last fraction of energy leaves in the exhaust gases, in the form of pressure and heat there too, although systems exist to recover a fraction (see turbochargers, the BMW Turbosteamer, or systems connected to a generator capable of transforming the "breath" of gases into electric current).
The problem is that the automobile industry is not a fundamental research institute and that for the moment, the old (more than 100 years) principle of reciprocating piston engine has never been exceeded when we consider the cost ratio (construction, maintenance, reliability) / consumption / production of driving force ...quick wrote:valve valves, -transmission of the piston power by the principle of crankshaft connecting rod which seems to me not famous for the passage of a maximum torque especially at the start and end of the race ....
