Cleaning Up The Black Smoke

black smoke from diesel engineDiesel technology is very well known for is durability, reliability, and overall ruggedness as applied to the trucking, construction, mining, and general power industries.   Without question, the acceptance and general economics of diesels have proven themselves time and again as the power source of choice.  However, as the markets and overall populations of diesels grew so did public awareness of the smell, sight and noise associated with them.   Not so long ago it was common place to see a 12-wheeler roaring down a highway belching black smoke.

Technology needed a boost and industry addressed it mostly due to over the road emissions requirements promulgated in the 1970’s.  Initially, diesel engine manufacturers balked at the requirement to reduce NOx and particulate and cries of ‘it can’t be done with today’s technology’ ensued.   Engineers quietly went to work on combustion development to gain a better understanding of what fuel characteristics had the biggest impact on NOx formation and particulate matter.  There was little doubt that something was going to happen about stack output.  The prime concern was as you get better with one attribute the other worsens as the two traits are inversely proportional.  Regardless, there was no doubt that increases in injection pressure and relative impacts to fuel droplet size were beneficial, so the call was put out to industry for 1000 Bar injection pressures.

In the day, pump-line nozzle systems held a large portion of the market with engines in the 6-12-liter category for trucks.  As the mid 80’s approached reliable injection technology of 1000 Bar was developed and implemented which aided in achieving 10.7 g/bhp.hr, but on the horizon was further reduction to 6 and 5 g/bhp.hr NOx and much lower particulate to .25 and .10 PM.

Injection pressure levels continued to increase, and rate shaping became a larger need.  Manufacturers realized that by controlling the rate that fuel is introduced into a cylinder, you can tailor the combustion event and ultimately the chemical release of emissions.  Not only did this help achieve required emissions standards but side benefits of quieter operation and easier cold starts emerged.  Things were looking up.

The prime hurdle, however, was that the technology of the day was not easily converted to achieve very high injection pressure, rate control and the ability to convert to digital fuel controls and total vehicle integration.  It was this impasse that started the development of rail technology in earnest.

Engineers knew that using an injector right at the cylinder was a very economical way of controlling combustion.  Unit injection has already been used for decades with mechanical systems and proved to be a reliable alternative to pump line nozzle technology.  But as with all systems, rate control and digital enhancement of injection control needed one element that was yet to be developed.  A reliable solenoid.

Simply put, delivery of very high fuel pressures (1800 Bar and beyond) was achievable, all you needed was something to start and stop the injection event.  If you could control how that start and stop happened digitally, you could vary your injection for each application.  Suddenly, a vision was getting solidified. An enhanced solenoid was the device to be implemented to achieve that desired result.

Ultimately solenoids with good durability, little hysteresis and economical manufacture hit the market.  Fuel system manufactures scrambled to gain acceptance and deal with the emotions of high-pressure rail or low-pressure rail and interchangeability.  Ultimately, it was up to the vehicle manufactures to achieve the required emissions levels, therefore, the evolution of what is now very commonplace in the industry transpired.

Certainly, there are many books written about diesel development.  Low-sulfur fuels, particulate traps, Urea injection, EGR etc. all play a role in modern engines but suffice to say, none of this would have happened without the development and evolution of the fuel management required as the heart of the technological enhancements.

Your Fuel Injection System: Keep It Clean

AMBAC PumpThe number one enemy of any fuel injection systems is contamination, plain and simple.  Whether it’s a modern-day rail system with operating pressures of 2-3000 Bar or a legacy pump running at 600 Bar, the introduction of foreign particles or substances can cause significant durability issues and shorten the overall life of your equipment.

Consider that many fuel systems have metal to metal sealing surfaces.  Non-gasketed surfaces capable of sealing injection pressure require very flat, very smooth and very clean surfaces.  The slightest variation in contact stress caused by foreign particles can cause leaks, and even of bigger concern is that the leak may not show up right away.   Costs to repair a leaking fuel system after installation can be excessive and create engine conditions that are very unfavorable to the user.

Similarly, sliding surfaces which are used extensively in pumping elements and normally fit to few micron, seal strictly on the merit of their diametral fit and surface condition of the mating parts.  When you consider a strand of human hair is 50-100 micron in diameter or a spec of dust runs 5-10 micron, it becomes easy to imagine that even the slightest levels of contamination can cause very big problems.

Normally OEM manufacturers use clean room environments with temperature and humidity control while sizing and matching components of fuel injection high pressure products.  Operators wear gloves, coats and head gear to ensure no foreign material is being introduced during the assembly process.  The room air is filtered, and shoe scrubbers are usually encountered when entering the room to ensure very clean, almost sterile assembly areas to ensure the highest level of cleanliness.  They understand the importance of keeping things clean to a very high standard.

Caution must also be used during servicing of fuel systems, as many shops are not equipped with this type of sophisticated equipment.  If you are experiencing short term failures, engine performance concerns, or inconsistent reliability, always start with examining cleanliness first.  Poor assembly and handling practices, lack of preventative maintenance for filters, hoses and transfer equipment, or a lackadaisical attitude about keeping your work areas clean can lead to unpleasant issues with your customers.  There is no substitute for a well-kept, hygienic shop.

Consequently, an ounce of prevention can result in pounds of cure with sound cleanliness practices and consistency within your processes.  Keeping it clean is by far the most important attribute to have to achieve a durable and reliable diesel fuel system regardless of make, model, age or size.

Turbocharger Failure Modes Part Two

Turbocharger Failure Modes Part Two

You may have read about the most common causes of failures in turbochargers in our most recent newsletter. If you missed the article, you can read it here on our blog.

In this article, we have outlined some additional common failure modes of turbochargers and some tips on how to identify these root causes.

  1. Lack of oil
  2. Foreign debris
  3. Hot shut downs
  4. Engine tuning

 

As we look at some additional failure modes, one thing to remember is that there is always evidence of how the failure happened, but sometimes there are multiple factors contributing to the failure.

Lack of oil

If lack of oil is the cause of turbocharger failure, the proof will be fairly straightforward. There will be bluing from excessive heat and galling of the metal. There can also be a transfer of the bearing material onto the shaft.

Foreign debris

Foreign debris in the engine is also fairly obvious. At full load turbo speeds, any debris that comes from the air box as a result of a a dirty or missing filter will easily cause a catastrophic failure. There will be noticeable fins broken off of the compressor wheel. If the damage is to the turbine (hot side) of the wheel, barring any excessive bearing clearances, internal engine damage could have occurred. This damage could be in the form of small pieces (including spark plug tips, glow plug tips, pieces of valves) coming through the combustion chamber and into the turbine housing.

Hot shut downs

Hot shut downs are very common. Whether in mountainous areas, hauling a load, or racing, the turbo must be allowed to cool down before shutting off the engine. On my vehicles, I have a pyrometer in the exhaust stream so I can monitor the temperature. There are also aftermarket controllers that keep the engine running until the temperature returns to normal or for a pre-set time interval. If an engine is shut down while hot, the turbo burns off the protective layer of oil that needs to be there for the next start. After four or five times of starting the engine with no oil on the turbo shaft, the damage is done. This damage is compounded if the typical starting mode is “Stomp on the accelerator to hear the turbo !!”

Engine turning

There are many versions and degrees of engine tuning, and not all are detrimental. Some design parameters add a certain amount of safety with no harm to the turbo. There are also many methods of configuring the turbo to tweak the performance, but the law of diminishing returns can set in quickly. Particularly in racing and tractor pulling, where there is so much excess boost pressure, the entire shaft is in effect “pushed” into the thrust bearing, causing excessive end play and wearing out the thrust bearing prematurely.

Bottom line: I would make it a policy never to give a customer a replacement turbo or a refund without first analyzing the failed unit to try to determine the cause of the failure.
