Understanding Diesel Exhaust After-treatment Solutions

SCR is an advanced active emissions control technology system that injects a liquid-reductant agent (DEF) through a special catalyst into the exhaust stream of a diesel engine. Particulate matter and other exhaust emissions will oxidize and burn off in the catalytic process, so the exhaust comes out cleaner. Under normal use, the SCR system doesn’t require any user interaction when in use and there’s no maintenance other than keeping the DEF fluid full.

Telehandlers with engines over 74 hp use an SCR system that requires DEF. JLG considered end user applications, as well as owning and operating costs and reliability in the field, when choosing SCR and DEF for Tier 4 compliance.

Select JLG and SkyTrak telehandlers come standard with 74 hp engines that use DOC to achieve Tier 4 Final EPA exhaust emissions regulations.

A DOC is a device that utilizes a chemical process in order to break down pollutants from a diesel engine in the exhaust stream, turning them into less harmful components — similar to a car’s catalytic converter. DOC technology doesn’t require DEF and therefore eliminates the cost of the DEF and having to worry about keeping the tank full.

JLG offers engine options for its JLG and SkyTrak lines of telehandlers to meet varying application requirements.
