VOLVO PENTA INBOARD DIESEL
4-cylinder, direct-injected freshwater-cooled turbocharged marine diesel engine
TMD22P
Crankshaft power* 57.4 kW (78 hp)
* Power rating – see Technical Data
b c d
The TMD22P is a marine engine of
advanced design manufactured from
a
quality components and designed to
fulfil customer requirements.
Service life
The TMD22P is fitted with freshwater
cooling as standard. This reduces
internal corrosion and enables the
engine to maintain a consistent and
optimal working temperature under all
conditions.
Comfort
Smooth running with very low vibration
levels results from a dynamically bal-
anced design and high efficiency rub-
ber insulation h g f f e
The engine’s high torque provides
excellent operating characteristics to i j k l
TMD22P with HS25A
aid maneuvering, particularly in con- reverse gear
fined spaces.
Additional on board comfort features
are available from an extensive range
of matched accessories.
Environment o
The engine’s direct injection and ad-
vanced combustion system ensure
high efficiency and low fuel con-
sumption, which minimize noxious
n
exhaust emissions and enhance overall
enjoyment of boating. The TMD22P is
certified according to BSO II and SAV.
Transmissions
For increased flexibility, in both design
and installation, completely matched m
down angle hydraulic, and straight or
down angle mechanical reverse gears The engine illustrated may not be entirely identical to production standard engines.
