marine block and cylinder head
made from high grade alloy cast iron, without limitation in cooling and
unrivaled roundness of the cylinder gives exceptional life time for the liner.•Chrome-Molybdenum forged crankshaft, dynamically balanced•Pistons are cast from high silicon aluminum, with oil cooling channel in3-ring technology•Hardened valve-seats high performance NIMONIC valve material
•Elastic coupling on flywheel, design matched depending on application ENGINE MOUNTING Adjustable front and rear silent blocks capable to take propeller thrust. LUBRICATION SYSTEM •Exchangeable oil filter cartridge•Oil scavenger pipe through dipstick•Closed crankcase breathing system FUEL SYSTEM •Integrated high pressure UNIT INJECTOR with dual stage fuel-injectiontechnology, operated by overhead camshaft and rocker arms.•Electric fuel pump (automatic bleeding capability)•Exchangeable fuel filter cartridge Hydraulic pump optional
TURBO DIESEL EXHAUST SYSTEM Freshwater cooled exhaust manifold and seawater cooled exhaust elbow COOLING SYSTEM The STEYR Marine Engine 164 is designed for high performance.The innovative fuel injection technology enables an excellent torqueand speed range. Therefore adaptation to existing
marine propulsion systems can be performed easily.Remarkable features of the STEYR Marine Engines are the dynamicbehaviour and immediate response as well as the impressive
acceleration.SERVICE LIFE •Freshwater cooling system with thermostat control•Heat exchanger with integrated expansion tank system•Connection prepared for boiler/cabin heating system•Sea water pump with impeller, integrated and replaceable wear plates The STEYR Marine Engines are manufactured using high alloy materials toprovide enduring longevity for all running components. Using corrosion
resistant materials for the entire seawater system as a standard in the dual
circuit cooling system. Consequently designed solutions to meet the criteriaof marine environment guarantee the best corrosion protection for anyauxiliaries and electronic components in marine ambience. COMFORT The patented 2-stage UNIT INJECTOR fuel injection technology provides
for a worldwide approved and smooth operation noise (patented).
Noise emission levels are over the most important operating range below
the running noise of gasoline engines. The additional elastic separation of
the Mmonoblock against the aluminum casted engine housing reduces theengine related vibration transmitted into the hull therefore the noise levelon board is further reduced.Torque and speed range characteristic enable optimal matching to individualapplication while maintaining transmission, gear ratio and propeller dimensions.
The big choice of matched accessories fulfills the highest level of quality and
comfort for you on board of your vessel. EXHAUST EMISSIONS The trend-setting UNIT INJECTOR system already enables us today toconform with the valid emission regulations BSO II and SAV 2, respectively
we can fulfill the announced EPA – Tier 2 and suchlike emission regulations.
