Ricardo to display functional integration prototype of ADEPT 48V “intelligent electrification” diesel

Green Car Congress

Ricardo will display the first functional integration prototype of the Advanced Diesel Electric Powertrain (ADEPT) collaborative research project ( earlier post ) in public for the first time this week at the Low Carbon Vehicle Event (LCV 2014) in the UK.

This combined combined aggressive 50% downsizing of the engine with an electric supercharger for transient low-speed performance and a 12+X volt micro-hybrid stop-start and energy recuperation systems. It is capable of operating in exhaust temperatures up to 850 °C, at speeds up to 60,000 rpm and delivering a peak power of 2 kW (@12V).

Controlled Power Technologies Packages Its Switched Reluctance Systems in ‘RegEnBoost’ System for Enhanced Support for Downsizing

Green Car Congress

RegEnBoost integrates the three devices into a powertrain electrical power network (PEPN), which also incorporates a DC to DC converter and an enhanced lead acid battery, optimized for fast energy storage and release. No matter how low the engine revs, the 2 kW electric supercharger remains highly responsive and extremely fast acting.

Turbocharging and downsizing can also yield fuel consumption reductions. Downsizing is an important strategy applicable in combination with technologies that increase engine torque, such as turbocharging or supercharging. Part of the gain from advanced-level CI diesel engines comes from downsizing.

The fundamental challenge is to convert as much of the chemical energy in the fuel, into mechanical energy, as efficiently as possible at the prescribed flow rate. A sole single-stage compressor and single-stage exhaust turbine are used for pressure charging. Conversion efficiency is now the key. Turbocharger. Brake System.
