Engine, description
The machines are equipped with a Deutz TCD 2012 L04 2V engine.
The engine is a four cylinder, four stroke in-line diesel engine with direct injection, exhaust turbocharger and liquid cooling
system.
See Workshop Manual:
“Deutz Workshop Manual, Competency Class 3 TCD 2012 2V, Order No. 0312 1975 de” for adjustment and repair
instructions on the engine.
Order address: Deutz AG Service Information Systems Ottostraße 1 D-51149 Köln www.deutz.com Email: info@deutz.com
The exhaust is recirculated and returned to the combustion air in the cylinder head by anunregulated internal exhaust gas
recirculation system (IEGR), to meet the emission limits for the turbocharged engine. The exhaust contains only a
minimum amount of oxygen. A minimum amount of oxygen reduces the temperature peaks during combustion and
therefore contributes to reduction of the oxide of nitrogen (NO ).
Engine Identification Plate
The engine identification plate indicates: Engine model, engine number and performance data.The engine number is also
embossed on the crankcase. It is necessary to specify the engine model and engine number when ordering parts. The
direction of rotation is counter-clockwise looking at the flywheel. Firing sequence: 1-3-4-2 (cylinder No. 1 on flywheel side).
