Promising Delphi 1st-gen Gasoline Direct Injection Compression Ignition engine meeting ultra fuel efficient program targets

Green Car Congress

GDCI engine was significantly better than advanced production spark injection gasoline engines, and comparable to very efficient hybrid vehicle engines at their best efficiency conditions (214 g/kWh). This early work established that gasoline-like fuels with high resistance to autoignition are preferred for PPCI. Combustion stability.

Tsinghua study compares two diesel-gasoline combustion modes; both deliver high efficiencies and low emissions

Green Car Congress

The effects of gasoline ratio on indicated thermal efficiency of HCII and GDBF modes. Researchers at Tsinghua University have compared the combustion and emissions characteristics of two dual-fuel (diesel-gasoline) modes intended to integrate the advantages of both fuels to achieve high thermal efficiency and low emission targets.

Brunel to use Camcon Single Cylinder IVT in researching future powertrain concepts

Green Car Congress

Both conventional and unconventional event profiles can be achieved. The conventional camshafts are completely eliminated and valve position can be monitored throughout the event using a specialized sensor. Any valve event profile can be achieved and valve position can be monitored throughout the event using a bespoke sensor.

GM R&D study explores effect of temperature and O2 concentration on automotive low-load HCCI

Green Car Congress

A study by a team at the Propulsion Systems Research Labs, GM R&D has concluded that the combustion instability of homogeneous charge compression ignition (HCCI) at the low-load range is caused by lack of oxygen concentration rather than lower in-cylinder mixture temperature.
