Test bench runs on a CATERPILLAR 3618 engine have recently been successfully completed for the world’s first dual-fuel conversion on a marine high-speed propulsion engine. The project was initiated by Norwegian shipping line Fred. Olsen S.A. who chose HEINZMANN as a competent and innovative supplier of dual-fuel systems.
The dual-fuel system is operated by the latest version of HEINZMANN's MVC 01-24 EFI controller, actuating the specially developed, double-walled MEGASOL 200 II gas admission valves. This offers very flexible system configuration in order to achieve the best possible adaptation for any application. Together with an intelligent air path management controlled by HEINZMANN’s wastegate valve WG 70, it was possible to operate the engine with a conversion ratio up to 90% gas. As a result the calculations from the comprehensive simulation works executed by AVL were met exactly. The reliable ARIADNE Knock Control System was installed to operate the converted engine at the highest efficiency limits.
In collaboration with the Dutch company PonPower, HEINZMANN changed over the diesel engines on the vessel Argonon. The scope of supply included the dual fuel positioner, the gas valve E-LES 80 and the gas mixers.
The Caterpillar motor 3516 shows a speed of 1000 rpm and a nominal output of 1300 kW. Due to the changeover to dual-fuel operation, the pilot fuel is only 20 % and contributes 1300 kW to the nominal output. The ratio of gas fuel amounts 80 % of the supplied energy and therefore contributes 880 kW to the engine performance. In addition to enabling significant fuel cost savings, HEINZMANN supported PonPower in achieving decreased emissions and environmental pollutions.
Anglo Belgian Corporation (ABC) has equipped the new TESO ferry between Texel and Den Helder with two diesel and two dual fuel motors. There are two ABC 12VDZD and two ABC 12 VDZ motors, which are controlled by a HEINZMANN system. The ABC motors have a speed of 1000 rpm and an electrical output of 2000 kW.
The diesel engines are each controlled by a PRIAMOS DC1-03 and an StG 16, while the dual fuel engines are each controlled by a PRIAMOS DC1-04 DF, an StG 16 and an StG 6. The dual fuel engines are powered by a ratio of 90% to 10% gas to diesel. Therefore, not only has there been a reduction in fuel consumption, but also emissions can be reduced to a minimum.
HEINZMANN supplied the French company SDMO Industries S. A., based in Brest, with an ARTEMIS Dual-Fuel System. The Mitsubishi diesel motor, which is used by SDMO for a genset, could be successfully changed over to dual-fuel operation by means of the HEINZMANN system.
The Mitsubishi SR16R2-PTAW shows a speed of 1500 rpm and an electrical output of 2000 kW. After completion of the project, the pilot fuel showed a considerable reduction. The ratio of diesel to gas fuel amounts today 23 % to 77 %. This results not only in significant fuel cost savings, but also in a reduction of emissions and environmental pollutions.
After subsidies for palm oil discontinued by the German government, the operation of diesel engines with palm oil was no longer efficient. To remain profitable, generator sets increasingly depend on the use of natural gas or biogas. In this pilot project, a diesel engine was converted to dual fuel through a HEINZMANN system.
The MAN motor is characterized by a speed of 1500 rpm and a nominal electrical output of 400 kW. Due to the changeover, the pilot fuel is now only 30% and contributes 120 kW to the nominal output. The ratio of gas fuel amounts 70 % of the supplied energy and therefore contributes 280 kW to the engine performance. As a result, the municipal engergy supplier benefits not only from reduced fuel costs, but also contributes to decreased emissions and thus environmental pollutions.
HEINZMANN was given the commission of changing over a motor of Hummel Energie Holding GmbH to dual-fuel operation. Due to the installation of the dual-fuel system ARTEMIS, the goal of fuel cost savings and emission reductions were successfully achieved.
The Volvo motor Penta TWD 1643GE, which is applied for a genset, has a speed of 1500 rpm and an electrical output of 450 kW. Since the changeover to dual-fuel operation,the ratio of pilot fuel to gas fuel is 30 to 70 %. Thus, diesel contributes 135 kW and gas 315 kW to the entire motor performance.
In collaboration with HEINZMANN, the company Kraft Power Corporation, based in Ohio, USA, carried out the changeover of its diesel motor Mitsubishi SR6 to dual-fuel operation. After delivery and installation of the dual-fuel system ARTEMIS, the project was successfully completed, thereby achieving fuel savings and a reduction of emissions.
The diesel motor, which has a speed of 1800 rpm and an electrical output of 600 kW, is used by the American company for its genset. After the changeover to dual fuel, the motor is now driven by means of diesel (39 %) as well as gas fuel (61 %). The pilot fuel is therefore reduced to 186 kW and is supplemented by 294 kW of gas fuel.
HEINZMANN has supported Völkl Motoren Technik GmbH to change over the company's MAN diesel motor to dual-fuel operation. The main objectives were fuel savings and emission reductions. The project was successfully completed by delivery and installation of the dual-fuel system ARTEMIS.
The MAN D2842 V12 is used by Völkl for gensets. The diesel motor shows a speed of 1500 rpm and a nominal output of 350 kW el. Through the changeover to dual-fuel operation, the pilot fuel could be reduced by 50 % and is now complemented by gas fuel. Diesel and gas fuel contribute equally 150 kW to the entire engine performance.
