I DA U N I V E R S A L N ove m b e r - D e ce m b e r 2 0 1 6 68 comply with Stage IIIB, the company said a combination of external EGR and diesel oxidation catalyst (DOC) were used. Yanmar Another company which is gearing up for Stage V is Yanmar. The company has recently released three new turbocharged and after-cooled engines. The trio joins the company's existing TNV family of common rail engines which are Tier 4 fi nal, Stage IIIB and FOEN (Switzerland) certifi ed. These are the engines that Yanmar said it would offer for Stage V regulations from 2019. Yanmar, meanwhile, said its engines had already found favor with construction equipment manufacturers, especially for excavator and wheeled loader applications because of their lower fuel consumption, higher power density and a DPF which requires little maintenance. The new 1.6, 2.1 and 3.1 liter engines feature Bosch and Denso common rail direct fuel injection systems, full authority electronics and offer rated powers ranging from 33.3 to 88.4kW. Volvo Penta Volvo Penta said it had continued to introduce new products that optimized machine performance for customers, while at the same time offering lower fuel consumption and reduced emissions. It said it was attracting a growing following of OEMs in the construction and mining industries that are drawn to the performance and support of Volvo Penta products and services. Appli- come into force. Deutz's TCD 2.9 engine will produce up to 55kW, it said, and has a similar size and confi guration to its diesel equivalent. The new gas variants – called G 2.2 and G 2.9 – mark Deutz's entry into a line of business that offers future poten- tial, with LPG engines offering a number of advantages, it claimed. For example, they are said to be particularly well suited to equipment designed for use in the enclosed spaces of buildings, as liquid gas produces far fewer emissions than diesel. The engines also have a three-way catalytic converter that means they meet the Stage V emission standards without the need for a costly exhaust after-treatment system. Hatz Diesel Hatz Diesel has launched a new three-cylinder engine that complies with Stage V. The water-cooled three- cylinder 3H50 engine will be available from 2018. Hatz's engine is equipped with Bosch common rail technology – maximum injection pressure 1,800 bar – and the new model is similar to the manufacturer's existing four-cylinder design. Thanks to the turbo charger and the intercooler, Hatz said, the 1.5 liter engine had a maximum torque of 185Nm (at 1,600 to 2,000 ,rpm) and a maximum power of 42kW, but required an installation space of 0.25m3. And it said the new model did not need any exhaust after treatment, reaching the Stage IIIA and EPA Tier 4 Interim exhaust standards for 19kW to 37kW engines. To Engines continued from page 55
