Diesel Solutions

K.T. Automotive Products provides diesel solutions to our partners to help tackle common problems for their customers. Our products are proven to boost overall engine performance, remove those injector and combustion chamber deposits, and increase fuel economy.

The Problem:

All formulations of diesel fuel produce: varnish, carbon deposits, soot, and corrosion which restricts fuel and airflow to the engine resulting in:

  • Loss of Power
  • Loss of Performance
  • Stalling
  • Stumbling
  • Hesitation
  • Decreased Fuel Economy
  • Increased Emission
  • EGR Fouling
  • Expensive Repairs
  • Potential for Engine Damage

Due to the way diesel engines deliver fuel – carbonaceous deposits bake on internal systems and diesel EGR systems return sooty byproducts to the combustion stream – which compounds the build-up of deposits.

  • Further, High-Pressure Common Rail (HPCR) systems are more susceptible to the impact of deposits than prior generation systems. Due to the elevated pressure operations (as high as 44,000 psi), the tolerances between moving parts of HPCR systems are measured in single-digit microns.
  • The moving parts within injectors are an order of magnitude smaller and lighter than their unit injector predecessors and thus carry lower inertia to resist the binding effects of deposits.
  • Even deposits of a few microns thick can fill small gaps and cause moving parts like injector needles, command pistons, and metering valves to bind or stick.

HCPR systems also use sophisticated injection strategies that can involve six or more discrete injections during a single combustion. Delay or reduction in fuel volume during any one of these injections can have performance repercussions.

Common Deposit Sources are due to:

  • Fuel – oxidation, unburned/partially burned hydrocarbons
  • Fuel Additives – oxygenates added to improve the combustion process also tend to dissolve gums and move them further down the fuel system.
  • EGR – combustion by-products are recirculated to the intake system.

Injectors in the combustion chamber lead to the cooking of deposits over time. Driving conditions also contribute to the acceleration of deposit formation from short trips, stop-and-go driving, temperature extremes, trailer towing, and any situation creating higher-than-normal engine temperatures.

Internal diesel injector deposits (IDID) in high-pressure common rail injection systems can slow response, or cause sticking, of moving internal injector parts resulting in a loss of control of injection event timing and/or the amount of fuel delivered.

Due to the complex injection sequences utilized in common rail engines, the effects of IDID on performance range widely but can include:

  • Poor Operability
  • Reduced Fuel Economy and Power
  • Increased Emissions
  • Failure to Start
  • In Extreme Cases – Engine Failure
  • Intake Valves – intake valves are subject to carbon buildup on valve surfaces and stem.
  • Combustion Chamber – soot and unburned hydrocarbon deposits on combustion chamber surfaces which impair performance over time.
  • EGR Components – EGR gases deliver a sooty byproduct that gums up the EGR valve, EGR cooler, intake ports, and any sensors that are exposed to it.

The Solution:

A complete diesel fuel system service removes varnish and carbon and improves the flow of fuel and air to the engine resulting in:

  • Improved Power
  • Restored Performance
  • Eliminated Deposit-Related Stalling

  • Eliminated Hesitation
  • Restored Fuel Economy
  • Reduced Emissions
