High Pressure Injection diesel engines (CRDi, HPCR and HEUI) have been developed and introduced to meet the latest emission standards. Wonderful news for the world we live in! However, with the addition of this new technology and the introduction and constant modification of Ultra Low Sulfur Diesel, there are a flood of horror stories about High Pressure Injection diesel engines!
What is High Pressure Diesel Injector rattle?
The most common of these problems is Injector Rattle…
The sound will remind you of rapid machine gun-type rattle, or even excessive valve tappet noise. High Pressure Injection systems run incredibly fine tolerances, and are highly stressed due to enormous pressures (we’re talking above 20,000 PSI!) and extremely high operating temperatures. Because of the extremely fine tolerances and super-high temperatures in these systems, the injectors often stick because of inherently low lubricity of the Ultra Low Sulfur Diesel fuel. This condition causes “Injector Rattle”. This is a very serious problem and requires immediate attention to avoid expensive damage (Think sticking injectors causing gross over-fueling resulting in melted pistons!)
Contaminated diesel fuel can cause expensive problems
Unlike diesel injector systems of the past, modern high pressure diesel fuel components, including injectors and pumps, are totally unforgiving when it comes to fuel contamination. Very small amounts of water or contamination will wreck pumps and injectors. They’re pretty much non-repairable, so that usually means new components. High pressure fuel pumps and injectors don’t come cheap – usually around $1,000 or more per injector just for starters…
- Injector tips fouled by contaminants – incorrect spray patterns cause a host of problems including loss of engine power, poor and erratic performance, excessive diesel smoke, excessive fuel consumption.
- Injectors sticking or seized due to lack of lubrication – caused by Ultra Low Sulfur Diesel fuel, produces over-fueling which creates detonation inside the combustion chamber, which, if not corrected, will often result in melted pistons! BIG $$$
If you hear Injector Rattle from your diesel engine – alarm bells should be going off!
That’s the bad news…
Ultra Low cost solution to Ultra Low Sulfur Diesel problems
Here’s the good news – a low cost, extremely effective solution to most high pressure diesel related problems is available!
ULS Diesel Enhancer is the real life FIX for most High Pressure Diesel Injection, Ultra Low Sulfur Diesel problems!
ULS Diesel Enhancer cleans fuel pump and injector deposits, lubricates and frees up sticking injectors, and disperses contaminants as they form. This super concentrated product is proven to –
- very effectively clean and lubricate the entire fuel system
- reduce/eliminate exhaust smoke
- restore power and economy
- boost diesel lubrication properties, including upper cylinder lubrication
- provide exceptional anti-rust protection to pumps and injectors
It is a total diesel fuel system treatment! Use ULS Diesel Enhancer before overhauling or replacing your expensive injectors. Perfect for any diesel engine using Ultra Low Sulfur diesel!
(Had gasoline in your diesel? ULS Diesel Enhancer might just still save your pump and injectors!)
Choose the most appropriate ULS Diesel Enhancer size for your particular need. Various size options are available –
ULS Diesel Enhancer is added directly to the diesel fuel tank.
As a rule of thumb, and depending on the fuel consumption rate the engine achieves, the following is usually helpful in determining which size is most suitable for your application –
- 8 fl oz – treats up to 500 gallons (1900 liters) of diesel. This is usually enough to treat diesel-powered cars, small to medium pickup trucks, small agricultural tractors & machinery, small boats, small generators, etc.
- 16 fl oz – treats up to 1000 gallons (3800 liters) of diesel. This is usually enough to treat diesel-powered mid-size pickup trucks, box trucks, small RVs, medium agricultural tractors & machinery, medium boats, generators, etc.
- 32 fl oz – treats up to 2000 gallons (7600 liters) of diesel. This is usually enough to treat diesel-powered large trucks, RVs, large agricultural tractors & machinery, large excavators, dozers, large boats, etc.
- 64 fl oz – treats up to 4000 gallons (15,000 liters) of diesel. This is usually enough to treat 2 or 3 diesel-powered trucks, or a combination of trucks and other machines, boats, etc.
- 1 Gallon – this is usually enough to treat a number of diesel-powered large trucks & machinery, combinations of various machinery and/or boats, Fleet & workshops, etc.
ULS Diesel Enhancer is suitable for diesel engines only.
(32 fl oz = 946 mL, 1 liter = 33.8 fl oz)
