Volvo Penta Starting A Final Start/Stop Engine Option

Posted on April 2, 2014

Last year, Volvo Penta developed a new start/stop function for its 5.0 and 7.0 L Stage 3b/Tier 4 interim industrial diesel engines. The company has now announced that beginning in the fourth quarter of this year, the start/stop option will be available on the company’s Stage 4/Tier 4 final 5.0, 8.0, 11 and 13 L engines.

Designed to shut down the engine during extended idle periods and turn it back on when the operator presses a pedal or pulls a lever, Volvo Penta’s start/stop feature can reduce fuel consumption, noise and emissions. Because the feature prevents the engine from running unnecessarily, operators can save between 5 and 15% in fuel costs, depending on the amount of idling done in an application, Volvo Penta said.

Updated for the new Stage 4/Tier 4 Final engines, Volvo Penta said the system provides further benefits for OEMs and end users. Wiring and control units have been replaced with advanced software for enhanced reliability and a more intuitive cool-down system is used to identify the optimum time to shut off the engine after it has been running for a long time.

Volvo Penta said the start/stop feature has also been reconfigured to further lengthen engine life, with an improved starter motor and monitor to prioritize stops and starts so that fuel saving is balanced with component wear.

When an application has to start and stop frequently, it can be difficult keeping the emissions aftertreatment system running at an optimal temperature, Volvo Penta noted. The company has integrated an improved control on the Stage 4/Tier 4 final start/stop feature designed to keep the system running at the correct temperature.
