The main function of these systems is to suppress detonation caused by high temperature and pressure developed within the combustion chamber whenthe effective compression ratio hasbeen taken beyond the auto-ignition point by either a turbo or a supercharger. Water, with its high latent heat content,is extremely effective for controlling not only the onset of detonation but also the production of oxides of nitrogen in the modern leanburn engines. ERL's latest products are designed with great care to ensure each system meets the highest standards of both electronic and mechanical reliability.
