b'tools today are essential on a daily basis and can do anything from read proprietary codes to specific troubleshooting based on the fault that was read, and dealer-level bi-directional functionalities. With more sys-tems coming online, you continue to look for that all-in-one solution that can fix your entire fleet and maintains the quality of the OE. It looks like that is now available, with a tool that covers both diesel and gasoline engines.To have a better understanding, it is necessary to explain that engine developments are due to the search of optimization. Some of the rea-sons are monetary, like efficiency and fuel consumption, but others are environmental. The Environmental Protection Agency (EPA) sets very strict policies on other industries such as commercial, agricultural, and off-highway vehicles. Surprisingly, they are very lax on marine engines, and no diagnostics anti-pollution functions are available for the techni-cians, much less a dedicated electronic control module (ECM) for this purpose, contributing to worse air & water quality.With the standardization of communication protocols, the technology has been liberated, making the aftermarket more capable of bridging the existing technological gap.The Importance of Diagnostics This nautical particularity generates the coexistence of older and newer engines in the nationwide fleet. Some are still purely mechanical, others are electromechanical, and more and more are managed by an electronic control unit (ECU). With evolution, technicians and maintenance go for Correct Maintenance behind with the necessity of mastering not only all engine makes, but also all fuel systems. However, some of you are still keeping and purchas-ing mechanical engines because you can repair them with a toolbox and enough knowledge.Although the industry is lagging behind other types of machines and vehicles, its just a matter of time. Most of the marine diesel engines lack an exhaust gas recirculation (EGR) control system; aftertreatment systems such as the DPF (diesel particulate filter), DOC (diesel oxi-dation filter), SCR (selective catalyst reduction); and, of course, urea dosing system and aftertreatment fuel. European manufacturers, such as MAN, Scania, and Volvo Penta are taking the lead in that aspect. In Europe, its currently mandatory for the newer engines sold to carry and systems cant you cover nor maintain on your own because theyaftertreatment systems when used in lakes and rivers. Its probably ar-need a specific diagnostic tool? How much business are you losingriving to North America soon. But, dont be afraid, weve got your back when your ferries are not in use?
