THE AEM DIESEL & PETROL 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 Diesel’s exhaust gas recirculation (EGR) system. AEM’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 & Petrol 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).

WATER/METHANOL INJECTION ADVANTAGES FOR ENGINES:

Reduces Air Inlet Charge Temps
Water/methanol’s “liquid intercooling” effect on turbo Diesel engines can reduce air charge temps by as much as 100 degrees, and deliver a more oxygen-rich air charge.

Enhances Combustion & Efficiency
In addition to cooling air inlet temps, as the water absorbs heat in the combustion chamber and converts to steam, the steam’s expansion rate increases the mean effective cylinder pressure without causing dangerous pressure spikes. This effective increase in cylinder pressure combined with methanol’s promotion of complete combustion allows your Diesel engine to burn fuel more completely. When fuel is being burned more completely less is wasted, which can increase fuel economy.

REDUCES EXHAUST GAS TEMPERATURES (EGTs)
Because Diesel vehicles using water/methanol injection burn fuel more completely, less un-burnt fuel is present in the exhaust manifold where it can flash ignite to increase EGTs and create particulate matter (soot). Water/methanol injection eliminates this secondary combustion of raw fuel in the exhaust manifold to reduce EGTs by up to 250 degrees, and reduces harmful particulates to extend engine life (and that expensive particulate filter).



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 harness’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.
 

Simplified Wiring
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.
 

Integrated Boost Safe Feature
The controllers for AEM’s Water Methanol systems include an integrated “Boost Safe” 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, “Boost Safe” 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
AEM’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
AEM’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 engine’s horsepower output (see chart below).
 

Revised Flow Control Strategy for More Linear Fluid Delivery
AEM’s engineers spent extensive time revamping 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.

Nice and comfy, light duty and feel great.
Size: X-Large, Color: Light Green
What they may lack in "durability" i.e. very light and thin = not going to last all that long, they make up for in fit [yes even for wide shoulders], comfort and style. If you want them to last, suggest a gentle cycle and just take ot easy on them. They are light, thin, and airy. Nice summer shirt.

A true vacation find!
Size: Medium, Color: Light Green
Really nice choice. Got it for my husband and he really liked the style. I loved how it fit on him and the lightness of the fabric. Great for hot, sunny weathered days, or warm nights. A true vacation find. Both comfy and stylish. He would have preferred it be 100% cotton, but I think he didn't really mind after steaming it. He commented on the color too. A beautiful sage green!

Well made, comfortable and flattering
Size: 3X-Large, Color: Light Green
Nice material. I ordered the 3XL because my hubby has a big belly. It fit him well and was slimming. He wore it as a guest to an outdoor wedding. He looked nice and was comfortable all night.

Nice but short
Size: X-Large, Color: Lavender
Yes, I purchased this shirt for my husband to wear on Mother’s Day. He looked so handsome and the color complimented his skin tone beautifully. The only con that my husband expressed was that the shirt was short but was comfortable and the fabric felt good on his skin. He is 6’3” and usually wears an XLT. Coofandy, Please make these shirts for taller, longer torso men!

Expensive Look Without The Expense!
Size: Medium, Color: Black, Size: Medium, Color: Black
Sizing: If you’re a true large like me and close to but less than fifteen pounds overweight, normal length and with a 44” chest, buy a medium and use the shirt to inspire you to lose the beer belly. If you have similar dimensions but are overweight by up to thirty pounds, get the large. Materials: The mediums are manufactured to 70% synthetic, 30% linen—which is a great mix, as is doesn’t have to be ironed after it’s washed and hung to dry, nor does it have to be ironed every time you get up from a chair. I’ve had many 100% linen shirts and sure, they look great after you spend thirty minutes ironing them, just to look like a crumpled up newspaper after you get out of your car. My experience with linen shirts is what brought me here. Unboxing the shirt: I threw it on an ironing board the moment I unbagged it. I tried the Synthetic setting on the iron—it wasn’t enough. I then tried the Wool setting and set the steam setting to constant medium to high. It worked great. I didn’t have to press down at all, just lightly glided the iron across wrinkled areas of the shirt. Within five minutes, the shirt looked like a hundred-dollar shirt. The material is light, yet feels heavy to the touch and breathes very well in the heat. The hidden buttons give a clean, modern look that allows the shirt to be worn with anything from shorts and sandals to dress slacks and shoes in a club. I like to wear these shirts, untucked with a pair of jeans and western boots. This shirt is very comfortable, fits nice and is extremely versatile.
