Renewable Fuels

Deutz has released biofuel versions of its 2012 and 2013 engines, now officially approved for operation with rapeseed oil according to DIN V 51605. Deutz said that with the utilization of biofuel, the engines remain compliant with the emissions limits of EU Stage 3 and EPA Tier 3 and Tier 4 Interim.

From a technical point of view, to cope with the operation with rapeseed oil according to DIN V 51605, both the 2012 and 2013 engine series have been equipped with a Deutz fuel management system, which consists of a fuel control fully integrated into the engine control system and a dualtank system with automatic switchover from diesel fuel to rapeseed oil and vice versa.

The system also includes a fuel pre-heater for the rapeseed oil circuit to ensure reliable operation at low temperatures. The dual-tank system is required, as the engines are started with diesel fuel and run on this fuel under low-load conditions to optimize operation.

Additional features that are essential for the utilization of rapeseed oil, include the Deutz DCR common rail technology and an electronic engine control system, which manages the entire combustion process, switching from conventional diesel to rapeseed oil during engine start and low-load operation while optimizing all parameters to minimize fuel ingress into the lube oil.

New Engine

Deutz has introduced a watercooled, four-cylinder 2011 engine with power outputs of up to 99 hp as an expansion of the offering for Tier 3/Tier 4 Interim.

Engine Technology

Deutz Corp. announced the release of the 2015 Series for use with natural gas, covering 240 to 320 hp. The 12 L, V6 and the 16 L, V8 lean-burn engines achieve 1.2 g/bhp-hr, below the current EPA regulations and are designed for stationary use in the oil, gas and industrial markets, the company said. The engines are assembled and tested at Deutz Corp's headquarters in Norcross, Ga.

Deutz also announced the development of its own telemetry system for industrial engines, whereby the current condition of the engine and all machinery can be evaluated in real time using key engine data such as coolant, oil and fuel levels, which are transmitted to a central server.

Deutz said that its telematics communicates in both directions, so that it not only "keeps an eye" on the machine but also enables remote access to defined functions. For example, Deutz said it is possible to shut down the engine from the remote access, and to start it, provided it meets all necessary safety measures.

The addition of telematics is especially applicable for engines operating remotely, such as engine driven irrigation pumps, Deutz said. Additional features of the new system include a "geo-fencing" theft protection and an Internet interface enabling users to stipulate the operating range of their machinery. If this limit is exceeded, a warning signal is emitted or a text message is sent to the owner.
