Moroso Engine Oil Accumulators function as supplementary oil reservoirs designed to safeguard an engine from potential damage during periods of decreased oil pressure. These accumulators are integrated into the engine's pressurized oiling system. They utilize compressed air to deliver a reserve of oil back into the engine when oil pressure falls below a predetermined safe level. Once normal oil pressure resumes, the accumulator automatically replenishes its reserve from the engine's oiling system, thereby preparing for the next potential pressure fluctuation.
