Fuel Injectors are very precise instruments. When working perfectly, they atomize fuel to deliver the ideal ratio of fuel-to-air necessary for efficient combustion. The ratio is calculated using the science of Stoichiometry. The sensors in your car are constantly recalculating the ratio pursuant to a fuel-mapping program. This program is developed partly with the help of on-board computers recording your driving-style. The factors for calculating the ratio depend upon both air and engine temperature, load demands, and atmospheric pressure.
We run into problems from the inconsistent quality of fuel we use and the overnight oxidation of fuel in all cars. Many of the higher-octane fuels contain detergents that promote better injection performance. You may immediately notice a slight increase in performance after running a tank of high-octane by accident. However, cars have been using less and less high-octane fuels over the years due to the economy. And simply adding detergents … Read more
