THE AEM DIESEL WATER/METHANOL INJECTION SYSTEM ADVANTAGE
Water/methanol injection (WMI) systems reduce air inlet temps and enhance combustion efficiency on turbo Diesel applications, which allows an engine to deliver more power with less effort. Water/methanol injection also offers a host of benefits that promote engine longevity, including the reduction of carbon deposits left by a Dieselâ€™s exhaust gas recirculation (EGR) system. AEMâ€™s Water/Methanol Injection Systems for turbo Diesel trucks and SUVs utilize the most robust hardware combined with more advanced features than any other comparably priced water/methanol injection system.
Water/Methanol for Diesels of all Boost Levels
AEM Electronics offers two different water/methanol controller designs for HD and Diesel trucks:
One is a Boost Dependent HD Controller and has an on-board MAP sensor (up to 40 PSI) with a molded in nipple for a boost hose pickup (PN 30-3301 with 5 gallon tank, PN 30-3303 tank-less).
The second HD controller features a multiple input design. The Multi-Input controller can be programmed to work with a 0-5v signal from an external MAP sensor for Diesels running over 40 PSI of boost, or with a frequency based Injector Duty Cycle (IDC) signal, frequency-based mass airflow (MAF), or 0-5v voltage-based MAF signal (PN 30-3351 with 5 gallon tank, PN 30-3352 tank-less).
Robust, Easy to Use Controllers
The new HD controller designs feature 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. A plug is integrated into the HD controller housings for mating to the redesigned wiring harnessâ€™s positive-lock connector. The Boost Dependent HD controller housing (PN 30-3301 w/ 5 gallon tank, PN 30-3303 full kit without tank) has a molded-in, barbed nipple to accept a boost hose (up to 40 PSI) and a wiring legend on the back. The Multi-Input controller (PN 30-3351 w/ 5 gallon tank, PN 30-3352 full kit without tank) 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. Both controller housings feature an easy to access integrated fuse and molded mounting tabs.
The wiring harnesses for AEMâ€™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.
Integrated Boost Safe Feature
The controllers for AEMâ€™s Water Methanol systems include an integrated â€œBoost Safeâ€ output feature that monitors the entire injection system and triggers a ground signal via an output if it detects a voltage-related error (short, bad connection, broken wire, overheated pump, high or low voltage signal, etc.), allowing users to define their failsafe strategy from something as simple as flashing a warning light to more advanced strategies like pulling boost or ignition, or switching fuel maps on a standalone engine management system. Combined with the integral and highly accurate conductive low-fluid switch in the tank, â€œBoost Safeâ€ can also put your engine in safe mode before the system runs dry. This exclusive feature is found only on AEM Water/Methanol Injection Systems.
Heavy-Duty High Pressure Injection Pump
AEMâ€™s internally-bypassed water/methanol injection pump does not cycle on an off and provides quiet, smooth operation. It features robust construction including integral hose fittings, EPDM seals and a Santoprene diaphragm that provides consistent and reliable fluid delivery.
Low-Profile 5 Gallon Tank
AEMâ€™s Diesel Water/Meth systems are available with or without a low-profile 5 gallon tank. The 5 Gallon tank includes a high-tech conductive low fluid level indicator with a positive lock connector and color matched wires to the wiring harness, and baffles to reduce fluid slosh.
Machined Billet Injectors and Nozzles
AEM includes two precision-machined billet injectors in its Diesel Water/Methanol Injection kits that feature an integral check valve to prevent unintended fluid flow. Three billet injector nozzles are included for matching water/methanol flow to an engineâ€™s horsepower output (see chart below).
Revised Flow Control Strategy for More Linear Fluid Delivery
AEMâ€™s engineers spent extensive time revamping the HD water/methanol controllerâ€™s flow control strategy for a more linear flow output delivery. This means that the flow delivery better matches an engineâ€™s need for water/methanol injection, which further improves charge air cooling and reduces EGTs.
- Boost Dependent and Multi-Input HD (external 0-5v MAP or MAF/frequency MAF) controller designs feature large adjustment knobs, integrated plug for harness connection, integrated fuse, covered status light and test button for enhanced splash resistance and mounting tabs
- Wiring harness is terminated with a positive-lock connector on one end with color-coded wires to ease installation, integrated pump ground circuit and additional wire for optional on/off solenoid
- â€œBoost Safeâ€ failsafe output included (for complete failsafe under all conditions, see Water/Methanol Failsafe Device)
- Heavy-duty high-pressure injection pump features integral fittings, a Santoprene diaphragm and EPDM seals to resist corrosion. Our pumpâ€™s quiet, smooth operation is almost undetectable
- Two precision-machined billet-aluminum injectors with integral check valves include multiple nozzles to cover a wide range of horsepower levels
- 20 feet of Nylon injection tubing included
- LED dash light for system status and low fluid warning
