The “adventures” that took place last summer with prices at Russian gas stations once again attracted the attention of car owners to the topic of reducing fuel costs.
Regardless of the presence or absence of a turbocharging system in the engine design, the octane number of gasoline suitable for powering the unit depends primarily on the compression ratio in the cylinders. It is enough to find out what it is, and you can adequately assess the safety of the idea of ”powering” the AI-92 engine. If the compression ratio (the ratio of the free volumes in the cylinder at the two extreme positions of the piston) does not exceed 10, then the engine can operate very well at 92. If it is 10.5 or higher, it is better to pour 95 into the tank to avoid detonation (explosive ignition) of the fuel in the combustion chamber.
Please note that all “engines” are now equipped with sensors for this detonation. As soon as the engine control unit detects this, the problem is corrected using small shifts in the ignition timing. This allows you to drive with less octane fuel than is required for a particular engine. Although, of course, not a single octane corrector of a modern engine can cope with gasoline, for example, A-80.
How is it safe for your car’s engine to find out if it can specifically ‘feed’ AI-92? To start with, we stock a 20 liter AI-95 canister and a neck for pouring fuel into the tank. We will carry it with us in the trunk throughout the experiment.
This is an emergency reserve for quickly increasing the octane number of the fuel in the tank – in case the engine is not satisfied with our experiment. Then we bring the level of the usual AI-95 on the indicator on the trash can to half and add AI-92 to about 20% of the volume of the car’s gas tank. We drive the resulting mixture and see how the engine behaves.
In the event that it runs smoothly and does not ignite control engines, we roll out the added volume and buy 20% of the 92nd again. We observe the engine’s response and if there are no signs of trouble, we continue topping up. If at some point an ominous icon of problems with the engine lights up on the dashboard, it means that the “trick failed” and it is time to end the experiment. We urgently send an “emergency jerry can” to the gas tank and drive to the nearest gas station to fill up with fresh AI-95.
Well, if the power source does not show dissatisfaction with feeding it with 92, we gradually increase its share in the fuel system to 100%, thereby ensuring in practice that it is possible to easily switch your vehicle to fuel with a lower octane number and a more humane price tag.
