Audi’s performance SQ5 diesel features electric compressor with mild hybrid system

Green Car Congress

Energy is stored in a compact lithium-ion battery with an electrical capacity of 10 Ah located beneath the luggage compartment floor. It helps out whenever the exhaust gas flow provides too little energy to drive the turbocharger, i.e. when starting off and accelerating in the low-rev range up to 1,650 rpm.

New powertrains for updated BMW X5 and BMW X6; PHEV and 48V MHEV

Green Car Congress

The energy required for the electric power boost is stored in a 48V battery located in the engine compartment. The BMW X5 xDrive50e accelerates from rest to 100 km/h (62 mph) in 4.8 The latest version of the eight-cylinder engine powers both the new BMW X5 M60i xDrive and new BMW X6 M60i xDrive from 0 to 100 km/h (62 mph) in 4.3

Toyota Central R&D developing free-piston engine linear generator; envisioning multi-FPEG units for electric drive vehicles

Green Car Congress

Toyota’s FPEG features a hollow step-shaped piston, combustion chamber and gas spring chamber. Toyota envisions that a pair of such units (20 kW) would enable B/C-segment electric drive vehicles to cruise at 120 km/h (75 mph). The FPEG consists of a two-stroke combustion chamber, a linear generator and a gas spring chamber.

with the EPC working in tandem with the exhaust turbocharger—the full-size S models achieve a constant torque of 700 N·m across an engine speed range of 2,500 to 3,100 rpm. The EPC supports the TDI’s turbocharger whenever there is insufficient energy in the exhaust gas for a spontaneous torque buildup—e.g.,

Upgraded diesel engine joins Honda Civic line-up in Europe

Green Car Congress

Honda has made significant improvements to the engine and the exhaust system to maximize real world performance. The diesel powertrain has a new NO x Storage Converter (NSC) system with larger catalysts and a higher content of noble metals (silver, platinum and neodymium) that store nitrogen oxide gas until the regeneration cycle.

Audi power-dense 2.5L TFSI engine with electric biturbo delivers 591 hp from 2,480 cc; 48V subsystem for the turbo

Green Car Congress

Audi’s electric biturbo combines a conventional gas-driven turbocharger with a secondary electrically driven compressor; in exterior appearance it is almost identical to that of a conventional turbocharger. Turbochargers are typically driven by energy from the exhaust—i.e., lb-ft), with acceleration from 0 to 100 km/h (62.1
