Robust, Easy to Use Controller Designs
The new 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 controller housing for mating to the redesigned wiring harnessâ€™s positive-lock connector. 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. It also features an easy to access integrated fuse and molded mounting tabs.
AEMâ€™s Water/Methanol Injection kitâ€™s wiring harness is terminated with a positive-lock connector on one end and has 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 in 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 and 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.
1 Gallon and 5 Gallon Tanks
AEMâ€™s gas Water/Methanol Injection Systems are available with or without a compact 1 gallon tank or low-profile 5 gallon tank. A more accurate, conductive low level fluid sensor is integrated into our tanks and features a positive lock connector with color-matched wires to the wiring harness. The sensor eliminates any chance of incorrect readings due to interference from debris.
Machined Billet Injectors and Nozzles
AEM includes one precision-machined billet injector in its gasoline Water/Methanol Injection kit. It features 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 graph in specs tab).
Revised Flow Control Strategy for More Linear Fluid Delivery
AEMâ€™s engineers spent extensive time revamping the 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 optimizes charge air cooling and detonation control.
WATER/METHANOL INJECTION ADVANTAGES FOR GAS ENGINES:
Reduces Air Inlet Charge Temps
The term â€œliquid intercoolingâ€ with water/methanol injection refers to a highly atomized mist of water/methanol that is injected into the airstream and begins to evaporate. As it does, this evaporative effect reduces air charge temps by as much as 100 degrees, and delivers a more oxygen-rich air charge.
Reduces Detonation (Knock)
Water absorbs heat, and methanol is a cool burning, anti-knock rated fuel. When combined and introduced into the inlet stream, they can effectively increase your vehicleâ€™s anti-knock index so you can reliably increase boost pressure and advance ignition timing using pump gas.
Reduces Carbon Deposits
Modern vehicles fitted with Exhaust Gas Recirculation (EGR) devices for emissions control promote heavy carbon build up inside the air intake. This carbon build-up can create â€˜hot spotsâ€™ in the combustion chambers that can cause detonation. Water/methanol injection has a â€˜steam cleaningâ€™ effect that reduces this carbon build up, and in some cases can increase fuel economy.
