Mass Sensor Testing…An important HHO Conversion Step?

To do a mass sensor testing for your hho engine, you have to know how mass sensor works and recognize it’s different forms. Mass sensor is use to monitor air volume going to your intake combustion process. When it was first introduced, this sensor came with a vane or movable door which is connected to a mechanical linkage. So when a volume of air pass thru the vane or door, a wiring connected to the linkage would determine how much air has passed thru the opening. This passage was measured in voltage which is fed to the engine computer.

This type of mass sensor is called vane type and it only measures the air volume. To do an accurate mass sensor testing, it has to include the air temperature and pressure of the incoming air. When added, it helps improved better engine performance. A second type of mass sensor has both temperature and pressure included and it is called a “hot wire” mass sensor. It is characterized by having a wire elements which comes in contact with the passing intake air.

In this 2nd type of mass sensor, the wire itself is monitored for changes in wire resistance while being exposed to passing air. More air passing means cooler wire resistance and vice versa. This change is measured by the engine computer which inturn could calculate the rate of fuel flow for the fuel injectors. Please note that on the first vane type mass sensor, the movement of the linkage is measured by voltage. And in some hot wire mass sensor, voltage measurements are also applied on certain engine models.

When mass sensor testing is done on these types of mass sensor, all you have to do is measure the voltage on each one of the wires going to the mass sensor while the engine is running. When done during idle, one of the wires being measured will have the value of the voltage change whenever the rpm is disturbed. So when you increase the rpm, the voltage reading should change which is reflected in the digital voltmeter measurements.

Problems comes when you have a “frequency” type mass sensor. On this sensor, the wire element itself has an oscillating frequency readings whenever the rpm is varied. Most of this “frequency” type mass sensor will have 5 or more wirings but instead of measuring the voltage, you need to measure the frequency which can be done by setting your voltmeter in the frequency range. Doing the mass sensor testing is almost the same as the voltage type wire mass sensor. To find the right wire, make sure you have the right mass sensor wiring diagram.

Caution:

Before buying a hho mass sensor adapter for your hho engine, make sure you ask the hho vendor if the mass sensor they are selling will work on voltage or frequency mass sensor settings. Otherwise, the mass sensor adapter will not work on your hho engine.

Increase Gas Mileage Using HHO…Is This Now Doable?

To increase gas mileage using hho and considering that the worst part about a hydrogen generator is that you have to start from scratch and put this thing together. For someone like me who works on cars all the time, it’s not a big deal. However, for someone who doesn’t stick his or her head under the hood, it’s almost unfair. It’s just that everyone wants to improve gas mileage in their vehicles so you have to take what you can get.

To increase gas mileage using hho, it’s basically trial and error per vehicle. One of the first things you need to think about is the type of gas that is being used. If you have a vehicle that runs on diesel, it won’t get the same benefits as one that runs on unleaded. If you just bought a 2008, you won’t get the same results as a 1995. You get the idea. Eventually you may be able to get the same benefits, but for now, it’s a long way off.

There are a few things you will want to try in the beginning that will not only increase gas mileage using hho, but also change the feel of your car as a whole. While using a hydrogen generator is based on just one fuel cell, there are some who are using as many as six. Granted, it’s not as simple as putting a six-pack of generators underneath the hood and away you go, but for larger vehicles it could be the next step down the road.

Then there are ways to increase gas mileage using hho gas intake or even decrease and keep track of it right while you’re driving down the road. You have gadgets that can have everything turn on and off from the turn of the ignition and so many others we really can’t list them all here. It’s just amazing how one little tweak can make an ordinary increase an unbelievable one in the matter of seconds.

When it’s all said and done, though, you should really let someone who is qualified to install a hydrogen generator. Even though most of the information out there suggests you can do it yourself, it’s still not recommended. However, it’s understandable if you want to try, which is why I am writing this for you anyways. No sense on doing it by yourself, right? Click here if you need a mechanic.

The Efie Problems…What You Can Do About It!

Efie problems usually occur when you run your hho gas engine without warming it up. Other serious changes to fuel mixture can happen also if the sensor enhancer resistor setting is too high so that the average voltage setting of the oxygen sensor will increase resulting in open loop conditions. First of all, when talking about your regular oxygen sensors types, it applies to what they call a narrow band oxygen sensor where your average voltage is around 0.450 volt. This type of sensor is also characterized by the use of 1 to 4 wires connections.

The efie problems are prevalent during start ups based on what hho people are reporting online. Unless they wait for the engine to warmed up, then the efie begins to work better. As a matter of fact, a few reports say that if you apply the efie right away upon start ups, your engine will run rough. So how do you avoid it? Two things: put a toggle switch to control when to apply it. In one efie enhancer developed just recently, I saw a Utube video where the efie maker put an automatic delay circuit inside the efie itself.

A detailed efie problems are shown being fixed here in this video. The efie gadget has both a power switch to turn it on and a built-in delay circuit so that the oxygen sensor will wait for your engine to warm up. This prevents accidental rough engine starting and failure for the computer to go in close loop. Finally, he allowed the efie user to adjust the oxygen sensor voltage for optimum use. This strategy should be applied during efie selection before using it in your hho gas saver.

Notes:

Again, this is not an endorsement by ATS of the video suggested efie product shown here. We are just exploring all the possibilities to give you the choices for solving these efie problems.

Beware of efie enhancers when applied to wide band oxygen sensors. Unlike the old type oxygen sensors, its voltage reading borders beyond 1 volt. This requires a different efie sensor enhancer setting altogether. Proper efie enhancer setting will be discussed later.
