Deutz diesel engines BOMAG 
type TCD 2013 or a 6-cylinder engine TCD 2012

Series 4 single drum rollers are powered by 4 or 6 cylinder Deutz diesel engines type TCD 2013 or a 6-cylinder engine TCD 2012.
The engines are water cooled in-line engines with EMR3 electronics.
The engines are mainly designed in two-valve technology with turbo charging and intercooler. They are highly compact and come with a Deutz-Common-Rail injection system, called DCR in short.
All engines are designed with exhaust gas recirculation and thus reach emission values complying with EPA/ COM/ Tier/ stage lll
The engines are characterized by the following positive features:
  • compact design
  • low noise level
  • almost vibration free operation
  • low fuel consumption
  • low exhaust emission EPA/COM IIl
  • high power density
  • excellent access to all service locations.
  • high reliability
  • low running costs,
  • long lifetime

Deutz Common Rail (DCR) injection system for TCD 2012 / 2013
The diesel engines type TCD 2012 and 2013 are equipped with a "Deutz Common Rail" injection system, DCR in short.
The English term "Common Rail" indicates that the system is based on a common rail. It describes the use of a common high pressure fuel line with corresponding branches to supply all cylinders with fuel.
The "Common Rail" injection is an injection system for combustion engines, in which a high pressure pump pressurizes the fuel to a high pressure level. The pressurized fuel fills a piping system, which is permanently under pressure while the engine is running.
The general idea is the total isolation of the pressure generation from the actual injection process. An injection solely controlled by mapping is only possible under this condition. Injection timing and injection quantity are controlled by the engine electronics. The electric signals control an electrically operated valve per cylinder, which is integrated in the injection nozzle. The short distances between valve and injection nozzle result in short pressure rise times, which has a positive effect on the combustion process and its control. Various types of injection van be realized, e.g. pre-injection, main injection and post-injection. These are freely controllable, in dependence on the control unit.
The electric control is accomplished by the electronic control unit (EDC16) with EMR3, in dependence on the operating parameters. The system is capable of providing a wide range of limp-home functions, should any of the sensors fail. This ensures a reliable and safe completion of travel and work.

1 Fuel filter high pressure
2 Fuel low pressure sensor (5-7bar) B145
3 High pressure pumps
4 Fuel lift pump
5 Rail (high pressure pipe up to 1600 bar)
6 PRV (max. rail pressure limitation 1600bar)
7 Rail pressure sensor (B935)
8 Injectors (Y148)
9 FCU Fuel Control Unit (Y137)
10 Engine control EDC16 - EMR3
11 Fuel filter with water separator
12 Hand pump
Under normal conditions the rail pressure is between 300 and 1350 bar
The PRV is set to 1600 bar
If the PRV is defective or always open, the pressure in the rail will only build up to max. 700 bar.
The rail pressure must be at least 1.5 bar to start the diesel engine
The fuel low pressure sensor is located after the fuel filter and the pressure is normally between 5 and 7 bar.
The solenoid valve of the Fuel Control Unit (FCU) is dead, open towards the tank.
The voltage applied to the injectors is normally approx. 40 V.
