Bosch’s Starter Motors and Generators division,
recognizing that large-displacement
engines place great demands on starters, has
a new addition to its 24-volt starter motor
portfolio: the HEF109-L large heavy-duty
starter motor for off-highway applications.
The powerful starter motor is claimed to generate
18% more power than the company’s
M (medium) type starter motor on which it is
based, and delivers a maximum output of
9.2 kW. This is enough to reliably start
engines with up to 28-liter displacement.
The company described the new starter as an
excellent choice for particularly large engines
that previously have been difficult to start
with single starter-motor configurations. This
more powerful single-starter solution makes
a more complex parallel-starter system
unnecessary. The technology is designed to
achieve a mileage of up to 14,000 operating
hours in off-highway applications. The
design of the HEF109-L is especially compact,
making it particularly suitable for applications
where installation space in the
engine compartment is limited. High thermal
robustness ensures reliable starting of large
engines even at very low ambient temperatures
or in extended starting sequences.
For applications involving even larger
displacement engines, Bosch offers parallel
starting systems employing the newly
developed starter; diesel engines with displacements
of up to 84 liters and gas-powered
engines with displacements of up to
168 liters can be started reliably under
normal conditions.
