Myths about gas equipment (HBO)
The collection of misconceptions about gas and gas equipment has recently ceased to be replenished. Either the fantasy has dried up, or there is no special reason to invent something new. You should be curious to know all the "terrible truth" about gas, and maybe dispel your own doubts.
First imagine the proudly frozen profile of the interlocutor and strained through the teeth: "I earn enough to ride on gasoline." Studies have shown that the use of gas fuel is economically feasible for 30-35% of the vehicle fleet. And to earn more (or spend less) will not refuse any millionaire. Of course, for real money-worths, there are less "bucks" in one sitting at all, but we're not Rockefellers, we just have a proud profile.
Next comes a whole list of technical pearls, defending the correctness of which the authors strive to periodically use fists or an improvised tool as decisive arguments.
Pearl is the first (the same main): "In the engine burns out."
At what in most cases it sounds exactly as it is written, and only in rare cases technically literate people specify that the head of the block, not the cylinder walls, burns, and not the same gasket between the steering wheel and the seat, namely the exhaust valves. Well, the fact is a fact, and the duration of gas burning is indeed higher than gasoline (low-octane), and it is theoretically possible.
The point is that at the time of opening the exhaust valves, the gas-air mixture in the cylinder still burns and, as a consequence, the exhaust valves must overheat. But:
a) this happens on gasoline engines because of incorrectly exposed ignition (and where is there, sorry, gas?)
b) Even the venerable specialists from the magazine "Behind the wheel" could not prove the correctness of this statement (for the sake of justice it should be noted that they did not refute). And finally:
c) Correctly exposed ignition or use of an octane equalizer will forever close this question for you.
The second is the widespread statement that the installation of a gas supply system leads to an increased risk of fire. Well, what can be said here?
So in general, it is, because the two fuel systems in one car - is the complication of the design, and if you do not monitor the condition of the pipes and hoses (which for gasoline and gas systems is included in the list of works performed in the framework of maintenance), then There may be malfunctions that could cause a fire.
However, this does not cause any complaints or doubts. They say, as a rule, about the danger of placing a gas cylinder in the trunk, drawing terrible pictures of the consequences of the explosion. And that's strange: a balloon made of 3.5-4mm steel, placed in the trunk - it's scary and can explode, and the fuel tank, in thickness not much different from the can, located in the arch of the rear right wing of VAZ 01-07 is fine.
In reality, a gas cylinder equipped with shut-off valves with safety valves is capable of withstanding a severe blow, and even the breaking of the main pipes will not cause any significant and fire-dangerous leakage. Destruction of the same cylinder can occur only in a situation where the driver and passengers will, alas, do not care what happens to them and the car after the impact. For example, after a load of freight moving at a speed of 80 km / h on a stationary car.
Confirmation can serve as the presence of second-hand gas cylinders in a perfectly working condition on the dismantling of broken foreign cars (and machines on parsing are not burned, and cylinders are not smoked).
Of course, the very word "GAZ" carries a certain warning of danger, but it should be remembered that the propane-butane mixture used in most cars is normally heavier than air, which prevents the formation of a gas-air mixture, and the point of ignition of this mixture itself higher than that of a mixture of gasoline vapors with air.
A number of issues and objections concern directly the compatibility of gasoline supply systems with gas systems. Examples include the drying of rubber seals and clogging of jets in carburetor vehicles, failure of injectors and a gasoline pump in cars with injected fuel.
It's time to exclaim: teach "materiel" or read the instruction manual !!! Well, it is written in black and white everywhere that a car equipped with a gasoline system should start the engine on gasoline with a subsequent transition to gas, that the fuel tank should never be empty, and that the petrol pump on cars with electric fuel injectors is not switched off. Saving fuel should not go to the point of absurdity, unless, of course, you want to fill up the ranks of opponents of gas, having previously spent money on repairing the gasoline supply system.
