On turbo Diesel truck applications, water/methanol injection systems reduce air inlet temps and enhance combustion efficiency which allows the engine to deliver more power with less effort. It also offers a host of benefits that promote engine longevity, including the reduction of carbon deposits left by a Diesel’s exhaust gas recirculation (EGR) system. AEM’s Water/Methanol Injection Systems for turbo Diesel and naturally aspirated HD trucks utilize the most robust hardware combined with more advanced features than any other comparably priced water/methanol system.
AEM’s on-demand progressive Multi-Input controller for AEM’s PN 30-3351 Diesel Water/Methanol Injection kit features a multiple input design that enables users to install AEM’s Water/Methanol Injection Kit on ultra-high boost turbo Diesels (above 40 PSI) using an external MAP sensor. The Multi-Input controller works with an external 0-5v voltage-based external MAP sensor, a frequency based input for Injector Duty Cycle (IDC), frequency-based mass airflow (MAF), or a 0-5v voltage-based MAF to ensure the proper amount of water/methanol injection at all points along the engine’s power curve. AEM’s engineers spent extensive time developing the HD water/methanol controller’s flow control strategy for a more linear flow output delivery. This means that the flow delivery better matches an engine’s need for water/methanol injection, which further improves charge air cooling and reduces EGTs.
The new HD controller design features large, turn-resistant knobs and larger numbering to easily set accurate start and full activation points, with covered status LED and test buttons for added splash resistance. The Multi-Input controller has an easy-to-remove plug covering the programming dipswitches and a programming legend on the back for the 0-5v and frequency based settings, an easy to access integrated fuse and molded mounting tabs.
The wiring harnesses for AEM’s Water/Methanol Injection kits are terminated with a positive-lock connector on one end and have color-coded wires to ease installation. Both the power and ground wires for the pump are included in the harness which simplifies the wiring process and eliminates any chance of the pump accidentally activating from a short in the system. An additional wire is included for adding an optional on/off solenoid to stop fluid flow when the system is inactive.
AEM’s PN30-3351 HD Diesel Water/Methanol Injection System includes a low-profile 5 gallon tank with a high-tech conductive low fluid level indicator, a positive lock connector, color matched wires to the wiring harness, and baffles to reduce fluid slosh.
