Homogeneous Charge Compression Ignition

(HCCI) Engine Control

Search SwRI

A way to control Homogeneous Charge Compression Ignition (HCCI) engines targeted for series hybrid vehicles was researched by engineers at Southwest Research Institute (SwRI).

Approach

Control fueling rate, boost level, exhaust gas recirculation (EGR), intake charge and coolant temperatures
Maintain maximum rate of pressure rise (MRPR) in cylinder

Challenges

Monitor MRPR as feedback for control
High number of sensors and actuators

Tools Used

Rapid Prototyping Electronic Control System (RPECS™)
SwRI custom high speed data acquisition and analysis system (MRPR feedback)

The HCCI controller developed by SwRI is still in use today; it has been further developed and production derivatives are in operation on demonstration vehicles.
