Researchers from the Polytechnic University of Valencia (UPV) have designed a new engine to decrease the environmental impact of the most common type of lorries that travel on European roads—those that weigh between 18 and 25 tons. From their laboratories at the CMT-Thermal Engines of the UPV, they propose a new configuration that unites all the benefits of hybrid and dual-fuel combustion engines.
