CPT launching water-cooled electric supercharger for commercial diesel engines

Green Car Congress

At the 17 th Supercharging conference this week in Dresden, Controlled Power Technologies (CPT) will launch what it says is the first water-cooled electric supercharger developed for “quasi-continuous” boosting of commercial diesel engines, including those developed for off highway applications.

Viable exhaust-driven on-board ethanol reforming for improvements in fuel economy and emissions

Green Car Congress

A team at Monsanto and colleagues at AVL Powertrain have successfully designed and demonstrated an onboard low-temperature ethanol reformer that can be driven by exhaust heat. Many papers have described high-temperature steam reforming of ethanol at around 600 °C but.this temperature is too high to be driven by engine exhaust.

Hyundai showcasing new downsized turbo engines and 7-speed dual-clutch transmission; i40 48V Hybrid, i30 CNG

Green Car Congress

To keep the engine unit as small as possible, the exhaust manifold is integrated within the cylinder head and can therefore be cooled efficiently using the cylinder head water cooling system. These efforts result in faster warm-up of the catalyst and ultimately in reduced real-world fuel consumption and emissions.

Downsized 4.0 TFSI for Audi S8 cuts fuel consumption 23% compared to predecessor; cylinder deactivation and start-stop

Green Car Congress

Audi’s principle of downsizing: “ Forced induction replaces displacement ” One twin-scroll turbocharger per cylinder bank compresses the fresh air. From each pair of cylinders, the exhaust ports lead separately to a manifold and the turbocharger housing; they are not combined until immediately ahead of the turbine.

Lotus Omnivore Engine Shows Up To 10% Better Fuel Economy Than Spray-Guided GDI Engines; Achieves HCCI At Extremely Light Loads

Green Car Congress

The automotive industry, including Lotus Engineering, has quite rightly advocated engine downsizing for four-stroke engines. Downsizing therefore isn’t vital and, due to the improved light-load efficiency and emissions performance we see with Omnivore, this technology approach and ‘upsizing’ could permit a more efficient engine.
