Additives for Managing Common Rail Diesel Emission Control Equipment

<p>Common rail diesel engines were introduced to meet the need for more stringent exhaust emission requirements. Fuel pumps, injectors, EGR valves, catalytic converters and diesel particulate filters are all integral parts of the emission control system.</p>

<p style=”background-color: #f4f7fa; border-left: 4px solid #003366; padding: 14px 18px; margin: 20px 0; font-size: 16px;”><strong>Short answer: most common rail emission control problems &mdash; injector rattle, sooty oil, smoke, EGR sticking and DPF restriction &mdash; trace back to deposits and degraded fuel. The right purpose-designed additives correct and control them, avoiding some very expensive repairs.</strong></p>

<p>Most of the problems encountered can be corrected and controlled with the correct use of quality, purpose-designed additives. Cost Effective Maintenance produces a range of products to manage common rail diesel (CRD) problems. Some of the problems regularly encountered include the following.</p>

<h3>Injector Rattle and Poor Fuel Economy</h3>
<p>Injector response is impaired, allowing over-fuelling and detonation rattle. System deposits and fuel lubricity issues are the most common causes. The high-pressure, high-temperature system can cause diesel to degrade in service, forming deposits and losing lubricity &mdash; it will also leave a black residue in fuel filters. <a href=”https://costeffective.com.au/product/crd-fuel-enhancer-for-common-rail-engines/”>CRD Fuel Enhancer</a> restores cleanliness and lubrication to pumps and injectors. After this step, surprisingly few injectors are found to really need replacing.</p>

<h3>Sooty Lube Oil</h3>
<p>This is usually related to injector malfunction, and can overload the oil, resulting in sludge and piston ring sticking problems. Full crankcase cleanliness can be restored safely using detergent-based <a href=”https://costeffective.com.au/product/flushing-oil-concentrate/”>Flushing Oil Concentrate</a>.</p>
<h3>Exhaust Soot &amp; Smoke</h3>
<p>Also caused by injector malfunction, but can be compounded by other factors mentioned below.</p>

<h3>Coking of Combustion and Exhaust Spaces (incl. Turbochargers)</h3>
<p>Poor combustion &mdash; also caused by injector malfunction, excessive short runs, light loadings, etc. &mdash; allows deposits to build up. <a href=”https://costeffective.com.au/product/ftc-decarbonizer/”>FTC Decarbonizer</a> added to the diesel will actively burn off combustion and exhaust carbon.</p>
<h3>EGR Valve Sticking</h3>
<p>Caused by excessive exhaust soot and carbon build-up. Excessive exhaust through the EGR causes additional soot and carbon in combustion and exhaust spaces &mdash; and inlet manifold deposits can build to alarming levels too. <a href=”https://costeffective.com.au/product/ftc-decarbonizer/”>FTC Decarbonizer</a> is used to burn off carbon and reduce exhaust soot production; used regularly, it keeps EGR valves cleaner and functioning properly. Inlet manifold build-up should be manually cleaned, but repeat build-up can be prevented with carbon control and/or injector control additives.</p>
<h3>Catalytic Converters and Diesel Particulate Filters</h3>
<p>These can become contaminated and restricted due to the upstream effects already described. Regular use of <a href=”https://costeffective.com.au/product/ftc-decarbonizer/”>FTC Decarbonizer</a> will clean up and keep clean both catalytic converters and DPFs.</p>

<p>Over time, neglect of any of the emission control components will likely have a negative and compounding effect on multiple components, necessitating a multi-faceted approach. Using purpose-designed additives can be extremely cost-effective in correcting these problems and avoiding some very expensive repairs.</p>
