Myths about gas equipment (HBO)
The collection of misconceptions about gas and gas equipment has recently ceased to grow. Whether the fantasy has dried up, or there is no particular reason to invent something new. You should be curious to know the whole "terrible truth" about gas, and maybe even dispel your own doubts.
First, imagine the proudly frozen profile of the interlocutor and filtered through his 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 fleet. And no one millionaire will refuse to earn more (or spend less). Of course, for real moneybenches, the benefit of less "bucks" in one sitting is not considered at all, but we are 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 improvised tools as decisive arguments.
Pearl first (he is the main): "In the engine burns through."
Moreover, in most cases, it sounds exactly as it is written, and only in rare cases, technically competent people clarify that it is not the head of the block that burns through, not the walls of the cylinder, and not the same gasket between the steering wheel and the seat, but the exhaust valves. Well, the fact is a fact, and the duration of gas burning is indeed higher than that of gasoline (low-octane), and theoretically this is possible.
The point is that at the moment of opening the exhaust valves, the gas-air mixture in the cylinder is still burning and, as a result, the exhaust valves must overheat. But:
a) this happens on gasoline engines due to an incorrectly set ignition (and where is it, excuse me, gas?)
b) Even the venerable specialists from Za Rulem magazine could not prove the correctness of this statement (in fairness it should be noted that they did not disprove). And finally:
c) Properly set ignition or the use of an octane equalizer will forever close this question for you.
The second is the widespread allegation that installing a gas supply system leads to an increased risk of a car igniting. Well, what can you say?
So in general, it is, since two fuel systems in one car are a complication of the design, and if you do not monitor the condition of the pipes and hoses (which is included in the list of works performed as part of maintenance for both the gasoline and gas systems) possible malfunctions that may cause a fire.
However, this is not causing claims and doubts. They say, as a rule, about the danger of placing a gas cylinder in the trunk, drawing scary pictures of the consequences of an explosion. And that's strange: a cylinder of 3.5-4mm steel placed in the trunk is scary and can explode, and the fuel tank, the thickness is not very different from the can, located in the arch of the rear right wing at VAZ 01-07 is fine.
In reality, a gas cylinder equipped with shut-off valves with safety valves is able to withstand the strongest blow, and even an open circuit of the main pipes will not cause any significant and fire-hazardous leakage. The destruction of the balloon can only occur in a situation where the driver and passengers will, alas, no matter what happens to them and the car after the impact. For example, after the arrival of a freight train moving at a speed of 80 km / h on a stationary vehicle.
The confirmation can be the presence of used gas cylinders in quite working condition on disassembling broken foreign cars (and the cars on parsing are not burnt, and the cylinders are not smoked).
Of course, the very word "GAS" carries with it some kind of warning about danger, but it is worth remembering 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 ignition point of this mixture higher than that of a mixture of gasoline vapors with air.
Another number of questions and objections directly concerns the compatibility of gasoline supply systems with gas systems. Examples include the drying of rubber seals and the clogging of the nozzles in carburetor cars, the failure of the injectors and the fuel pump in cars with fuel-injectors.
It's time to exclaim: learn "materiel" or read the instructions for use !!! Well, it is written in black and white that a car equipped with a gas-fuel system should start the engine on gasoline and then switch to gas, that the fuel tank should never be empty, and that the fuel pump on cars with electric injectors is not turned off. Saving on fuel should not reach the point of absurdity, if you, of course, do not want to join the ranks of the opponents of gas, having previously spent on repairing the gasoline supply system.
