Powered by GM Vortec 3.0L I-4IndustrialMPFI Capable Version (LMX):Multi-port electronic fuel injection (MPFI) version for gasoline or dual fuel applicationsCylinder head targets fuel injectors to back of intake valves for quick response to changing conditionsStainless steel MPFI fuel rail resists corrosion Gaseous Version (LW6):Customized for gaseous fuels only, taking advantage of the higher octane levels by using a higher compression ratio All Versions:Utilizes 58X crankshaft position sensing via either a VR Crankshaft Position Sensor or a Digital Crankshaft Position Sensor (at OEM choice). Digital Crankshaft Position Sensor enables use of and is compatible with GMPT MEFI Control System. All engines equipped with a HVS (High Voltage Switch) and coil iginition system.Sintered powder metal exhaust valve seat inserts for enhanced durabilityNodular iron crankshaft for increased strength and durability Designed to use gasoline, propane, and natural gasAluminum heads with premium valve seat inserts and hard faced exhaust valves for extended life on gaseous fuels58X crank-triggered, waste spark ignition system utilizes the coil pack, crankshaft position sensor and available ECM for accurate OEM-defined spark timing which cannot be altered by end userAluminum PFI-style intake manifold can be used for gaseous fuels (LPG or Natural Gas ) or can be up-fitted with the optional gasoline fuel system (shipped without throttle body unit )Dual takedown cast iron exhaust manifold with heat shield reduces radiated heat to nearby componentsEngine has a badge area on top where OEMs can place their own identifying badge1.4kW starter for faster starts at any temperatureThermostat with internal bleed for improved cooling system performance Industrial EngineAvailable OptionsAn electronic control module (ECM) for optimizing fuel and spark requirements is available in kit form (gasoline only).Available in low and high compression ratio. A proven history of performance and durabilityTypical Industrial Engine Shown(Fuel Rail and Injectors sold separately)Powered by GM The Vortec 3.0L engine, with the longest history of any industrial durability and reliability.Vortec 3.0L I-4Feature FocusThe Vortec 3.0L is currently used exclusively in marine and industrial applications. Whether on the water or on the job, the Vortec 3.0L delivers the durable power you need.The exhaust valve seat inserts in the cylinder head provide superb durability.The 8-port version cylinder head casting is used on all versions of the Vortec 3.0L engine. Certain versions of this common casting are machined to accept the MPFI Fuel Injection System. All GM industrial engines are Vortec engines. Vortec means uncompromised power outstanding power with no very little required maintenance.Powered by GM Vortec 3.0L I-4SpecificationsVortec 3.0L Specification FocusType: 3.0L I4Displacement: 181 cid (2966.59 cc)Engine Orientation: LongitudinalCompression Ratio: 10.5:1 (LW6), 9.2:1 (LMX, High CR)8.3:1 (LMX, Low CR)Valve Configuration: Pushrod Actuated Overhead Valves(2 valves per cylinder)Assembly Site: Toluca, MexicoValve Lifters: Hydraulic Flat TappetFiring Order: 1 - 3 - 4 - 2Bore x Stroke: 101.60 x 91.44 mmBore Center: 112.26 mmBore Area: 324.29 cmFuel System: MPFI Capable (LMX)N/A (LW6)Fuel Type: LMX: Gasoline (MPFI Capable)LW6: Propane, Natural GasHorsepower: 94 hp (70 kW) @ 3200 rpm (MPFI: Gasoline (LMX)) Low CR93 hp (69 kW) @ 3.0L rpm (MPFI: Gasoline (LMX)) High CR73 hp (54 kW) @ 2200 rpm (Natural Gas: (LW6))64 hp (48 kW) @ 1800 rpm (Propane: (LW6))Torque: 188 lb-ft (255 Nm) @ 1800 rpm (Propane: (LW6))178 lb-ft (241 Nm) @ 1600 rpm (Nat.
