Start/Stop For Tier 4 Final Engines

Volvo Penta has released the second generation of its start/stop function for industrial engines. First introduced in 2013, it is now available for its Stage 4/Tier 4 final D5, D8 and D11 diesel engines, as well as Stage 3/Tier 3 D11 diesel engines.

The start/stop function works by shutting down the engine during extended idle periods and turning it back on when the equipment needs to resume its operation again.

“Start/stop is one of our latest innovations for the off-road market,” said David Hanngren, product planning manager at Volvo Penta. “We developed this feature in close cooperation with our OEM customers. With our approach, they benefit from using start/stop as an integrated part of our offer, providing a proven solution that is fully protected by our warranty coverage. It is a winning combination.”

The system can save owners between 5 and 15% in fuel costs, depending upon how much idling there is in a given application. Emissions are also reduced, while a reduction in idling can keep the aftertreatment system at a better working temperature, said Volvo Penta, and with the engine turned off when it’s not needed, excess noise is also reduced.

On the company’s latest generation of start/stop, the hardware has been integrated into the engine ECU for greater reliability; a stronger, more robust starter motor has been incorporated to ensure durability; and a battery voltage monitor allows the system to check the battery status and ensure there is enough capacity for a re-start.

As with all Volvo Penta off-road industrial engines, those fitted with a start/stop system are covered by the company’s two-year, 3000-hour international or North American warranty, said the company.
