Sole SDZ-205 Common-Rail Commercial Diesel Engine Package

Description

High power density and smokeless combustion define the Sole SDZ-205 Common-Rail Commercial Engine for high-speed pilot vessels. This turbocharged and aftercooled 4-Stroke 4.1L Deutz-based diesel yields 165 BHP continuous rating at 2,100 RPM. Electronic common-rail injection cuts fuel burn, though fuel circuits require strict 2-micron water-separating filtration to protect 1,600 bar injection components.

Monobloc cast iron construction pairs four individual 4-valve cast iron cylinder heads with replaceable wet sleeve liners. A 24V isolated ground electrical system mounts a 4.0 kW starter and an 80A marine alternator. Dry weight reaches 1,157 lbs without transmission. Physical mounting stance dimensions measure 45.7in long by 29.3in wide and 33.9in high, featuring an SAE 3 housing, SAE 11.5 flywheel, and a 3.96 US gal oil sump capacity.

Key Features of Sole SDZ-205 Common-Rail

Commercial fleet skippers buy Sole SDZ-205 common-rail commercial engine packages to power offshore crew transfer vessels and fast harbor patrol craft. The SAE 3 bellhousing mates with Technodrive TM 170A or ZF 63A hydraulic down-angle marine transmissions.

• High-pressure common rail electronic fuel injection operates at 1,600 bar to eliminate exhaust smoke
• Wastegate turbocharger with seawater-cooled charge air intercooler yields 165 BHP continuous output
• Four-valve individual cylinder heads optimize airflow and simplify individual cylinder maintenance
• Replaceable wet sleeve cast iron liners enable complete engine rebuilds without removing the block
• 24V isolated ground electrical layout prevents galvanic stray current damage in aluminum hulls
• SAE 3 bellhousing and SAE 11.5 flywheel couple to heavy commercial hydraulic reduction gearboxes
• Tubular heat exchanger cooling isolates raw sea water from engine block passages

Dynamometer Bench Test Thermal Parameters

Dynamometer testing certifies 165 BHP continuous power at 2,100 RPM with 200 BHP maximum power at 2,300 RPM. Seawater-cooled charge air intercooling maintains intake manifold air temperatures below 120°F under sustained high-speed pursuit. Engine oil pressure registers 55 PSI at operating temperature across static bed inclinations up to 15°. Common rail injection pressure maintains 1,600 bar, while crankshaft journal tolerances remain within 0.0006in TIR to endure heavy torque reversal cycles during pilot launch boarding maneuvers.

Electronic Throttle Preventive Maintenance Schedules

Electronic CAN-bus throttle controls connect to digital helm stations with zero mechanical cable friction. Do not install this 4.1L electronic common-rail engine in remote commercial craft that lack clean fuel bunkering infrastructure or digital diagnostic scan tools.

• Evacuate 3.96 US gal of 15W-40 lube oil every 500 operating hours using the fitted sump drain pump
• Replace primary 2-micron fuel water separator filters every 250 operating hours to protect common-rail injectors
• Inspect heat exchanger tube bundles, raw seawater impellers, and sacrificial zincs every 1,000 run hours

Commercial Warranty Package Shipment Manifest

Solé Diesel provides a 2-Year or 3,000-Hour commercial marine manufacturer warranty. The shipping crate contains the common-rail engine core, selected hydraulic marine transmission, 24V starter, 80A alternator, digital electronic display panel, engine wiring loom, flexible mounts, oil drain pump, and factory service manuals.
