A. Performance Intake System- With the addition of any diesel performance chip, performance module, or diesel programmer; increasing air-flow is critical to higher horsepower gains without losing fuel mileage as well as extending the life of your turbo diesel engine.
B. Performance Chips and Programmers- Gaining more horsepower has never been easier. Most of our performance chips are plug and play or can be installed in under an hour.
C. Diesel Performance Exhaust- Back Pressure and high exhaust temperatures are two of the easiest ways to hurt your engine's life.
D. Gauges- Monitoring your engine's performance is one of the most important things you can do. The most important diagnostic to pay attention to is your exhaust temperature gauge. If you are interested more in performance you will want to monitor your turbo boost with a boost gauge and your exhaust temperature with a pyrometer gauge.
How Does a Diesel Engine Work?
Even though gasoline and diesel vehicles have become commonplace in today's day and age people take for granted exactly
how they function. Many people know that the only difference between a diesel engine and a gasoline engine is the fact
that the pump for the fuel is green rather than any other color, and even that has gotten plenty of people in trouble.
But anyway the reason it is important to understand the differences in how Diesel engines work vs. how gasoline engines
work is because that is what makes diesel performance possible is the way that they work. So in the coming paragraphs
we will outline how exactly diesel engines function.
First, we have the fact that gasoline engines take in a mixture of gasoline and air, once it has taken in
that mixture it compresses it and ignites the mixture with a spark from a spark plug. Diesel engines on the other hand
take in only air, once it has taken the air in it will then inject fuel into the compressed air. If you are not into physics or chemistry which we are not you might want to skip this next part but science states that when a gas is compressed the temperature rises, this is the scientific law I guess you could say behind the way that the diesel engine ignites. The cause of combustion in a diesel engine is in fact the heat of the compressed air, once the fuel meets the heat of the compressed air it will combust spontaneously, the spontaneous combustion of the fuel is possible because when the air is compressed it reaches temperatures anywhere from 700-900 °C or 1300-1650°F.
Second, The actual compression rate is a huge factor in both the efficiency of the diesel engine and the
ability to get more horsepower out of it. Typical gasoline engines have a compression ratio of between 8:1 and 12:1,
diesel engines on the other hand typically range anywhere from 14:1 and as high as 25:1. The higher compression ratio
of the diesel engines allow diesel engines to perform much more efficiently. To be able to fully tap into the capabilities of the diesel engine turbo chargers are usually added to aid in the compression of the intake air as well as what are known as aftercooler or intercoolers, these cool the intake air after compression.
Third, Injection of the fuel is another point where diesel and gasoline engines differ. Gasoline engines
usually use one of two methods, the first is carburetion, with carburetion the air and fuel is mixed awhile before it
enters the cylinder, the other method it what the call port fuel injection, this is where the fuel is injected right
before what is called the intake stroke, this is still done outside of the cylinder where the combustion will occur.
Diesel engines use direct fuel injection, this is where the diesel fuel is actually injected directly into the cylinder
where the combustion is occurring.
Now because of the fact that the injection of the diesel fuel takes place directly in the cylinder where the combustion is taking place this has made the need for quite a bit of experimentation with the actual injectors in diesel engines
themselves. Most people say that the injector is the most complex part on a diesel engine even more so with the
powerstroke injectors, powerstroke injectors are a beast all by themselves so we will explain them at a later date but
diesel injectors need to be so complex because this is where a large amount of power is gained or lost in the whole
combustion process. The injector itself must be able to withstand both the temperature and the pressure inside of the
cylinder while still being able to deliver the diesel fuel in a mist that is fine enough to allow for combustion. Part
of getting that mist to combust is getting the mist circulated in the cylinder so that it is evenly distributed. To aid
in the circulation of the fuel diesel engines have anything from special induction valves or pre-combustion chambers or
other methods of getting the fuel to mix the air in the combustion chamber to better the combustion process.
Most people say that the largest differences in the diesel engine vs. gasoline engines is the injection process as a
whole. Gasoline engines for the most part use what is called "port injection" or carbureation as opposed to the direct
injection that diesel engines use. With gasoline engines both the air and the fuel are mixed together and then that
fuel and air mixture is injected into the cylinder just before what is called the "intake stroke" and then that combined
mixture is ignited with a spark plug. It is in that very process where gasoline engines are limited as to how much
power they can have and how long the engine will last with more power, the reason is the fact that with the gasoline
engines the fact that the mixture of both fuel and air are being ignited together limits the compression ratio of the
engine. If you are wondering why exactly that is, it is because if the fuel and air mixture is compressed at too high
of a level then the mixture will spontaneously ignite, which might not sound like such a big deal because thats what it
is supposed to do anyway right? Wrong! If the fuel and air mixture combusts on its own it will cause a knocking sound.
Now because diesel engines are compressing only air the compression ratio can be much much higher. The reason the
compression ratio is so important is because Higher Compression = More Power!!!
We have talked about the gasonline engine having a spark plug, a lot of people wonder if there is any equivalent to that
in the diesel engine. The answer to that is well sort of, but not really. All of the combustion takes place due to the
heat of the compressed air, now some might ask, "well what if it is cold out and the air doesn't get hot enough to
ignite the fuel." The answer that question is that is actually becoming less and less of a problem. A lot of engines
still have what are called glow plugs, what these glow plugs do is assist in ignighting the fuel when the engine is
still cold, the reason they are called glow plugs rather than spark plugs is because they actually just glow more like
the wires in a toaster rather than sparking each time to cause the combustion.
