AS PART OF A FUNDED PROJECT, DEUTZ AG IS CURRENTLY DEVELOPING AN INDUSTRIAL ENGINE POWERED BY NATURAL GAS WITH THE OBJECTIVE OF DEMONSTRATING SPECIFIC PEAK PERFORMANCE.
Natural gas as an energy source for commercial engines offers great potential in two regards. Its world market price has dropped by approx. 70 percent in the last ten years and is expected to continue to develop positively in the coming years. In addition, natural gas can be produced relatively easily from electricity and thus regeneratively using power-to-gas. This offers the option of completely CO2-neutral mobility.
The DEUTZ TCG 5.0 monovalent high-performance natural gas engine unleashes its maximum output of 185 kW at 2500 rpm from four cylinders with a displacement of five liters. The maximum torque of 1050 Nm (equivalent to 26.5 bar effective medium pressure) is already available at 1250 rpm. These values are in the range of comparable standard market engines in the absolute top segment.
An optimal cylinder head for the combustion of natural gas has been specially developed for this engine. Two overhead camshafts are powered by gearwheels and ventilate the engine with four valves per cylinder. The TCG 5.0 is supercharged with up to three bar boost pressure via an exhaust gas turbocharger with variable turbine geometry (VTG). By using a three-way catalytic converter optimized for operation with natural gas, all current emission limits for on- and off-road applications are met. With the development of the TCG 5.0 HoLeGaMo (high-performance gas engine), DEUTZ AG is taking another important step in diversifying its product portfolio.
