VEGE Remanufactured DDF4 2.4L 148ci Multi Purpose Long Block Engine

Description

Hydraulic variable valve actuator screen clogging and piston ring carbon packing immobilize municipal utility sedans. The VEGE DDF4 Multi Purpose Long Block Engine eliminates oil consumption trouble codes during commercial long block repower maintenance. This 2.4L 148ci 4-Cylinder platform makes 180HP. Technicians must prime the electro-hydraulic variable valve actuator brick before engine start.

High pressure die cast A319 aluminum block with cast-in iron liners resists thermal bore distortion. This VEGE engine core features forged steel connecting rods, dual variable timing sprockets, and a forged steel crankshaft. Starter current demands 145A on 12V. Dry weight reads 290 lbs, oil pan holds 5.5 quarts, with block dimensions measuring 21in length, 22in width, 24in height.

Key Features of VEGE DDF4

Fleet mechanics buy VEGE DDF4 industrial engine rebuild units for demanding municipal vehicle fleets. Advanced electro-hydraulic valvetrain technology improves low-speed combustion efficiency while lowering tailpipe hydrocarbon emissions.

• Cylinder bore diameter finished to 3.465in ensures tight piston ring combustion sealing.
• Crankshaft stroke calibrated at 3.976in produces responsive torque across intermediate city speeds.
• Cleaned hydraulic actuator galleys ensure positive oil delivery to variable intake valves.
• Multi layer steel head gaskets eliminate combustion gas leaks under heavy thermal load.
• Deep skirt aluminum block design reinforces lower crankcase rigidity under acceleration.
• The DDF4 commercial core connects to compact front transverse automatic transaxles.
• High volume gerotor oil pump maintains continuous hydraulic pressure at curb idle.

Dynamometer Proofing Performance Specifications

Technicians test every DDF4 long block engine on automated dynamometer test cells before crate packing. Continuous run diagnostics verify 180 BHP and 175 ft-lbs torque output at 3800 RPM continuous load. Oil gallery pressure maintains 52 PSI at 192°F oil sump temperature. Exhaust gas pyrometers read 1140°F EGT across manifold branches. Cylinder compression hits 185 PSI across all four cylinders. Crankshaft center journal runout stays below 0.0002in TIR limit under dynamic bench resistance.

Field Service Boundary Requirements

Electronic drive-by-wire accelerator pedal requires 5 lbs resistance force for positive control feel. Never install this variable valve actuator engine into vintage carbureted chassis or heavy commercial cargo trucks.

• Drain break-in motor lubricant and replace spin-on filter element after 500 roadway miles.
• Check electro-hydraulic actuator bleed screw torque to confirm 12 ft-lbs cold.
• Torque cylinder head fasteners to 22 ft-lbs plus two passes of 90 degrees.

Standard Packaging Scope Warranty
