An inner combustion engine operates with a selected air-to-fuel ratio to realize optimum efficiency. When the engine receives an extra of gas relative to the quantity of air within the combination, it’s described as working with a fuel-rich combination. A simple instance is an engine that produces black smoke from the exhaust pipe, indicating unburned gas being expelled.
Sustaining the proper air-to-fuel ratio is important for gas effectivity, minimizing emissions, and guaranteeing engine longevity. The situation the place extreme gas is current can result in decreased gas economic system, elevated carbon deposits throughout the engine, and potential injury to catalytic converters. Traditionally, changes to carburetors had been a main methodology for correcting imbalances, however trendy engines depend on refined digital management programs for exact gas supply.
