Alfa Laval is introducing the E-PowerPack waste heat recovery system for ships. Able to convert waste heat directly into electrical power, the E-PowerPack uses Organic Rankine Cycle (ORC) technology to reduce ship fuel consumption and CO 2 emissions. The basic principle of an ORC system can be thought of as the opposite of a heat pump.

with technologies such as direct fuel injection, variable valve timing, exhaust-driven turbochargers, brake energy regeneration and Auto Start Stop function—about 60% of the generated energy is still lost, half of it being exhaust heat, with the remaining half as heat absorbed by the engine cooling system.

Renault Trucks, a member of the Volvo Group, is exploring the use of a Rankine-cycle-based waste-heat-recovery system for its long-haul trucks. With the system, enthalpy of the vehicle’s exhaust gases is recovered and then converted into electricity by a generator incorporated into the turbine. This is a total waste.

Starting from a energy-based powertrain simulation model validated on experimental data from the PHEV, the researchers conducted a first- and second-law analysis to identify the potential for engine waste heat recovery, considering a variety of driving cycles and assuming the vehicle operating in charge-sustaining (HEV) mode.

Researchers in China have developed a novel free-piston linear generator (FPLG) to recover exhaust waste heat efficiently from a vehicle engine. The two cylinders are alternately in the intake-expansion stroke and exhaust stroke. In a paper published in the journal Applied Thermal Engineering , the team from. Prototype FPLG.

Developed for hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs), BorgWarner’s innovative Exhaust Heat Recovery System (EHRS) can improve fuel economy by up to 8.5% The EHRS reduces mechanical losses by using the energy conserved within the exhaust gas. and reduce emissions significantly.
