VOLVO PENTA INDUSTRIAL DIESEL TAD1670-1672VE is a powerful, reliable and economical off-road Diesel Engine range built on the Volvo in-line six concept. World class fuel efficiency combined with a reliable exhaust aftertreatment system gives high uptime as well as low cost of ownership. No downtime for regeneration or decreased service intervals. Compact and simple installation SCR technology selected by Volvo does not increase amount of cooling capacity needed. As optional equipment all material needed in order to install the engine can be ordered from Volvo Penta. Installation guidelines as well as drawings and CAD models are easy to access. The result is an engine and aftertreatment system that is easy to install with minor impact on existing machine layout. Features & Benefits • Low cost of ownership and operation due to SCR technology • Proven and straight-forward design • Compact and simple installation Long experince with SCR systems in combination with base engine development reduces risk of downtime. Wellbalanced to produce smooth operation with low noise. • High power and torque available at low engine speed • Complies with EU Stage IV / EPA Tier 4f • Wide range of optional equipment, please see order specification • No regeneration needed Maximum power and torque available at low rpm. As a result noice as well as fuel consumption is very low. Useful engine speed for the TAD1670-1672VE is due to power and torque layout very flexible. Efficient injection as well as robust engine design in combination with optimised SCR technology and a light EGR contributes to excellent combustion and low fuel consumption. TAD1670-1672 VE complies with EU Stage IV / EPA Tier 4f emissions. Easy service & maintenance Easily accessible service and maintenance points contribute to the ease of service of the engine. As optional equipment possible to remote mount filters and service points.
