Southwest Research Institute (SwRI) has successfully demonstrated that its HEDGE (High-Efficiency, Dilute Gasoline Engine) technology, using cooled exhaust gas recirculation (EGR) and advanced ignition systems, suppresses low-speed pre-ignition in turbocharged gasoline direct-injection engines.

A fuel injector can be heavily damaged by a pre-ignition event (bottom); a new injector is shown above. A fuel injector can be heavily damaged by a pre-ignition event (bottom); a new injector is shown above. Pre-ignition in modern engines is largely attributed to oil-fuel mixture droplets igniting before the spark timing.

In the event of slippage it instantaneously engages a hydraulic power supply to transfer extra torque to the wheel with the most traction by modulating the differential from fully open to fully locked, and anywhere in between, depending on driving conditions. The system comprises a deactivation rocker arm and oil control valve.

Advanced after-treatment processes for exhaust gases enable ultra-low emissions in line with stringent Euro Stage VI standards that will be introduced in September 2016, requiring a 55% reduction in NO x emissions compared to Euro Stage V standards. A belt-in-oil design for the camshaft and oil pump drive belts.

A sole single-stage compressor and single-stage exhaust turbine are used for pressure charging. Measures must be taken to ensure that, in the event of failure of the turbine wheel, any resulting significant debris is contained within the car. This requires thinner, faster flowing oil. Again, this requires thinner oil.

The test engine for the paper was a 250cc single-cylinder unit with dual-camshaft-actuated reciprocating sleeve valves for induction and exhaust. The sleeve valves have a short heat rejection path directly to lube oil. During the valve open event, all but the top few millimeters are drawn past a lip seal into oil.
