Preventing Diesel Engine Runaway

 

 

Did you know that a tiny custom made valve can prevent diesel engine runaway? Do you know what happens during the process or how to prevent diesel engine runaway? In this article, we will take a close look at Diesel engine runaway and what can be done to prevent this incredibly dangerous condition. As professionals in the diesel repair industry, we know that these incidents may not be as common in recent years, however, we also know that the consequences of diesel engine runaway are as serious as they come.

 

What is Diesel Engine Runaway?

 

Diesel engines are increasingly common and continue to overcome many obstacles. In other words, diesel engines are no longer associated with high maintenance or excessive noise and can now compare or compete with even the most impressive gasoline engines.

 

As you know, diesel engines are also used to power mechanical equipment and vehicles across every industry. Due to an especially durable physique, diesel engines are suited to rugged environments and machines or vehicles that require constant use. Unfortunately, this also translates as an increased safety concern as there is likely to be more people present should an incident take place.

 

With this in mind, there are still certain aspects of a diesel engine that can leave the machinery or vehicle at risk. Diesel engine runaway is the most serious of these risks and a worst nightmare for drivers, operators and the immediate surroundings of a diesel engine.

 

As already mentioned, diesel engine runaway is a serious condition that can result in a diesel engine catching fire and even exploding. As the phrase suggests, this problem occurs when a diesel engine overheats, loses control and runs away with itself. Although the engine is destroyed, this frightening possibility is also a serious threat to the people and surroundings of a diesel powered machine or vehicle.

 

Exactly What Happens During Diesel Engine Runaway?

 

Diesel engines are often preferred over spark ignition engines for different reasons. Diesel engines are more economical with fuel and can withstand much higher temperatures which enables them to last longer than gas engines. For this reason, diesel can also convert heat into energy rather than expose of this heat through the exhaust, as you will see with a gas engine.

 

Unfortunately for diesel engines, this is precisely where a potential problem can arise.

 

Diesel engines use high temperatures for the ignition process but unlike gasoline engines, they do not use a “butterfly” to restrict the intake of fuel. In other words, there is no mechanism to shut off the engine when the RPM reaches an abnormally high level.

 

Why Does Diesel Engine Runaway Happen?

 

There is no one cause for runaway diesel and faulty fuel links, damaged fuel pipes and even overfilling a crankcase can initiate the process. On the other hand, it does not have to be a specific incident, for wear over time and age are the most common causes of diesel engine runaway.

 

To be more specific, machinery and vehicles that experience constant use are most at risk to diesel engine runaway. Poorly maintained engines are even more likely to experience this condition and as previously advised, the outcome can be fatal. In some cases, the vehicle can catch fire and when it comes to machinery, an operator can become trapped in a sudden inferno or explosion.

 

However, diesel engines have come a long way in recent times. In fact, a runaway diesel was once a common occurence but modern engineering has significantly reduced the number of such incidents. Electronic Control Modules can also use sensors to help prevent runaway diesel but there are always exceptions and parts can sometimes fail.

 

How to Prevent Runaway Engine Diesel

 

In short, regular maintenance can extend the lifespan of a diesel engine but modification is really the only reliable solution when it comes to preventing diesel engine runaway from happening.

 

You see, diesel is heavier than gasoline and has a much higher boiling point than water. Therefore, in order to prevent diesel engine runaway, a system is needed to shut down the air supply in the event of the engine reaching especially high levels of RPM. As a leader in the diesel repair industry, Diesel Tech Industires has developed a system that can safely monitor and prevent diesel engine runaway.

 

About the DTI Guardian System

 

The DTI Guardian System is a specially designed shut-off valve that can prevent costly damage to a diesel engine and protect drivers/operators from serious injury or even death. Unlike other shut off valves in the market, we have developed a much superior system that can safely shut off a diesel engine before any damage has taken place.

 

Moral of the story: Diesel engine runaway is a serious risk that every owner should seek to know about and avoid at any cost. That being said, now you know about it, what can you do to prevent it from happening?
