Cadillac fuel injectors are crucial to the efficient operation of the engine, delivering the fuel required by the engine for power production. The engine needs a precisely calculated amount of fuel to mix with oxygen in the combustion chamber to perform at its most efficient, producing reliable engine power and maintaining a low level of exhaust emissions. Good fuel economy depends heavily upon an accurate balance of fuel and air in the combustion process as well, providing a clean and efficient burn of the fuel with little waste. Mounted on the intake manifold of the engine, Cadillac fuel injectors are positioned perfectly to provide a precisely measured spray of fuel directly to the intake valves of the engine. The amount of fuel provided in the spray dispensed from the tiny tips of the Cadillac fuel injectors is constantly monitored and adjusted by the vehicle computer to allow the most efficient mix of fuel and air. The oxygen level in the air changes with air temperature and elevation as the vehicle travels, among many other factors that can alter the oxygen received by the engine, making a system of ongoing adjustment necessary for the best performance of the engine. The proper maintenance of fuel system components, especially the fuel filter is very important for the continued good performance of Cadillac fuel injectors, as they can become clogged easily from impurities in the fuel supply, interrupting the efficient delivery of fuel to the engine.
