A visual representation illustrating the configuration of a dual-line supplemental coolant injection system, commonly employed in high-performance engines, depicts the arrangement of components. This schematic delineates the plumbing of two separate supply lines feeding coolant to strategically positioned nozzles, enhancing charge air cooling and mitigating the risk of detonation under demanding operating conditions. Examples include diagrams showing the connections between a coolant reservoir, pumps, solenoid valves, and multiple injection points within the intake manifold or directly into each cylinder.
The value of such a system lies in its ability to significantly reduce intake air temperatures, which in turn allows for increased boost pressures or more aggressive ignition timing, resulting in enhanced power output. Historically, these systems evolved from simple single-line configurations to more sophisticated multi-line setups to provide more even and effective cooling across all cylinders. This development addresses the limitations of single-line systems, which may struggle to deliver consistent cooling to each injection point, particularly in engines with complex intake manifold designs.
