Reducing Diesel Engine Exhaust Emissions to Minimum Levels
Install the Dieselytic SX exhaust gas purifier/scrubber as close to the engine exhaust gas manifold outlet (or turbocharger outlet) as possible. Additionally the exhaust gas purifier should be installed in between the engine exhaust manifold (or turbocharger outlet) and the exhaust muffler. If there is insufficient room for exhaust gas purifier installation then locate the exhaust gas purifier immediately after the muffler. However, we recommend that the exhaust pipe, muffler and exhaust gas purifier be fully insulated with heat wrap tape. The higher the exhaust gas temperatures to the purifier, the higher the exhaust purifier oxidation efficiency. The higher the oxidation efficiency, the lower the exhaust gas pollutants. If there is no room for the standard exhaust purifier, we also manufacture exhaust gas purifier mufflers, which are designed to replace the stock original equipment (OEM) muffler or another OEM exhaust system component. . Call us with the make and model of your equipment to determine the correct exhaust gas purifier muffler that will meet your needs.
Consider wrapping the exhaust gas purifier/scrubber and interconnecting exhaust pipe with a thermal heat blanket. The heat blanket will prevent approximately 80%-90% of total heat loss from occurring, thereby increasing the exhaust gas purifier/scrubber oxidation efficiency.
Periodically clean the catalytic core of the exhaust gas purifier/scrubber for optimal performance. Lack of proper maintenance will increase exhaust backpressure restrictions and reduce oxidation efficiency. Clean the catalytic core every three months (every 1000 engine operating hours) if the engine is older, every 6 months ( every 2000 engine operating hours ) if the engine is new.
If engine smoking (black smoke) is a problem we recommend that the engine air cleaning element, air intake system, fuel injection system, injection timing, upper cylinder condition and exhaust backpressure restriction be checked by a qualified mechanic. Over fueling, engine wear, restrictive intake/exhaust flow or incorrect injection timing will increase black smoke, carbon monoxide, hydrocarbons and oxide of nitrogen levels significantly. Engine maintenance is the most critical factor in reducing exhaust gas pollutants.
For improved purifier performance and reduced pollutant emissions, the following should be incorporated:
Use diesel fuel with a sulphur content of less than 0.05% sulphur content and an aromatic content of less than 18%. The lower the sulphur / aromatic content reduces SOX emissions, particulates and improves purifier oxidation performance. Purchase diesel fuel from a well known major brand name supplier to ensure that the fuel is of good quality, relatively fresh, and has been properly stored.
Use low ash or no ash engine crankcase lube oils which exceed API service CG-4, CF-4, CF standards. Use only well known, brand name oils.
Oxides of nitrogen (NOX) emissions cannot be controlled by current purifier technology. To properly control NOX emissions we recommend that the ventilation air to the work area be supplied at a rate of 130 to 150 CFM (cubic feet per meter) per engine horsepower. Determine the maximum engine horsepower of each machine and multiply the total horsepower (of all of the machines) by 150 CFM. For example, 2 machines with a maximum horsepower of 80 HP each would require 24000 CFM (2 machines x 80 HP x 150 CFM = 24000 CFM). Use ventilation fans and ducting to supply and exhaust the minimum 150 CFM per horsepower to/from the work area. Normally we recommend that a ventilation fan(s) be supplied to draw air into the work area and a ventilation fan(s) be supplied to exhaust air away from the work area. The ventilation fans should be arranged to provide a cross flow ventilation in which the air is always in motion and free of any dead spots. Ventilation fans are available from construction equipment rental centers.
