____________________________________________________________________________________
The Deutz D2011L04i is a 4-cycle inline
4-cylinder diesel engine distinguished by its oil-cooled (integrated
cooler) design, eliminating the need for a liquid coolant system and its
associated components like radiators, water pumps, and hoses. This
engine belongs to the 2011 family, which is recognized for high
reliability combined with durability.
The oil cooling and lubrication system prevents corrosion and
cavitation, contributing to minimized running costs due to low
maintenance needs and reduced wear. The D2011L04i features direct
injection utilizing a pump-pipe-nozzle system and is offered with either
a mechanical or an optional electronic governor. Long oil change
intervals of up to 1000 hours and a very good load response ensure an
immediate power supply for a wide range of industrial and construction
applications.
The Deutz D2011L04i operates as a naturally aspirated, four-stroke,
compression-ignition diesel engine. The inline 4-cylinder configuration
provides inherent primary balance.

Firing order: 1-3-4-2
Aspiration: Naturally aspirated
Rated Power: 46 kW (62 hp) at 2600 rpm
Maximum Torque: 190 Nm (140 lb-ft) at 1700 rpm
Low Idle Speed: 900 rpm
Fuel Consumption: 223.0 g/kWh (0.366 lb/hphr) at 1800 rpm
The crankcase is constructed from high-grade cast iron for high rigidity
and low noise emissions. A distinctive feature of the 2011 family is the
integrated oil cooling system, where oil is used as the primary coolant
instead of a water/antifreeze mixture.
Crankcase Material: High-grade cast iron
Crankcase Design: Monobloc construction
Crankcase Breather: Closed-circuit crankcase breather
The cylinder head is a cross-flow design cast in grey iron. The valves
are operated via pushrods and rocker arms from a camshaft located in the
cylinder block. This arrangement uses two overhead valves per cylinder
(one intake, one exhaust).
Cylinder Head Material: Grey cast iron
Valve Arrangement: Overhead valve (OHV), 1 inlet, 1 exhaust per cylinder
Valve Train: Pushrod-actuated
Pistons: Three-ring design (two compression rings, one oil scraper ring)
Connecting Rod: Forged steel rod
Crankshaft: With integral counterweights
Camshaft: Forged steel shaft
The D2011L04i uses a mechanical "Pump-Pipe-Nozzle" (PPN) injection
system. Single injection pumps for each cylinder are integrated into the
crankcase, with high-pressure lines running to each injector. This
system is known for its robustness and serviceability.
Injection Pump Type: Individual mechanical pumps for each cylinder
(integrated)
Injection Nozzle Type: Multi-hole nozzle
Governor: Mechanical centrifugal governor (std); electronic engine
governor (opt)
Fuel Lift Pump: Integrated in V-belt tensioner
Filtration: Full-flow replaceable cartridge filter
Fuel Shutoff: Solenoid-operated shutdown device
The engine uses a forced-feed circulation lubrication system. In
addition to lubricating moving parts, the oil also functions as the
primary engine coolant. The system includes a gear-type oil pump and an
integral oil cooler (the "integrated cooler").
Lubrication Type: Forced-feed circulation with gear pump
Type of cooling: Oil-cooled (integrated cooler)
Oil Filter: Full-flow replaceable cartridge
Oil Capacity: 11.5 Liters (approx. 12.2 U.S. quarts)
Unlike conventional engines, the D2011L04i does not have a water jacket
or require a radiator. It utilizes an integrated oil cooling system
where a high-capacity oil pump circulates engine oil through channels in
the cylinder block and head, past an internal oil cooler, and back to
the sump.
Type of cooling: Oil-cooled (integrated cooler)
Oil Cooler: Integrated plate or tube type
System Voltage: 12 V or 24 V DC (application dependent)
Alternator: 40-60 A range
Starter Motor: High-torque solenoid-operated
Length: 710 mm (28.0 in)
Width: 465 mm (18.3 in)
