Saab Trionic : Saab Innovation

Posted on 19. Nov, 2007 by in 2000-2009, Innovations


The Saab Trionic innovation is an advanced engine management system that measures all areas that are part of the combustion process. This Saab trionic system also measures ionisation within each cylinder of the engine block while the car is running. The information gained from these measurements in the trionic system, ultimately control the turbocharing, fuel injection and ignition systems.

Saab Trionic was developed by Saab Automobile back in 1991. It was first implemented in the 1994 model year Saab 9000 as well as the new generation Saab 900 models.

There have been three types of Saab Trionic since the very beginning, starting with Saab Trionic 5. Saab Trionic 5 was first implemented in the Saab 9000 as well as the new generation Saab 900 series. The second type of Saab Trionic system installed in the Saab 9-3 and Saab 9-5’s included the Trionic 7 system. The Saab 9-3 Sport Sedan platform including the SportCombi use the latest version of Trionic called Trionic 8.

For more information as to the details of each of these systems, please consult a well seasoned and trained Saab service technician.

Here is a press release from 1994 that outlines the finer points in the Saab Trionic system.

This Saab-developed system automatically and instantly adjusts ignition, fuel injection and, in turbocharged models, turbo boost pressure, thereby offering both environmental and performance benefits. Previously, Saab Trionic was only offered on turbocharged 9000 models.

Powered by a 32-bit microprocessor, Saab Trionic engine management improves performance by constantly monitoring the combustion process, then adjusting engine operating parameters to eliminate, for example, harmful engine knock. The special “trick” within Trionic is the utilization of the simple spark plug, which performs double-duty by also serving as a combustion sensor. Ionization voltage is measured across the plug gap to determine combustion efficiency, and Saab Trionic then adjusts engine systems for optimal performance and efficiency.

Courtesy of Trionic, Saab engine performance is improved and peak torque is available at decreased rpm levels, which translates to greater acceleration capability at lower speeds.

By controlling the combustion process so stringently, Saab Trionic engine management also contributes to improved fuel economy and lower exhaust emission levels.

For its innovative design and application, Saab Trionic was recently selected as a finalist in the automotive category of the prestigious 1993 Discover Maaazine Awards for Technological Innovation. In addition, Saab Trionic was acclaimed for “technical innovation” by the Motoring Journalists’ Club of Denmark.

Here is an informational video taken of the Saab Trionic system “in application”.

  1. late-night stupidities » Eine Studie & 17 Gründe für Saab - June 24, 2009

    […] Die nächsten beiden Techniken arbeiten eher im verborgenen. Mit der Automatic Performance Control stellte Saab 1982 eine revolutionäre Motorsteuerung vor. Je der Qualität des Kraftstoffs (Oktanzahl) wurde die Leistung des Motors so reguliert, dass kein schädigendes Klopfen auftritt. Durch die damit mögliche höhere Verdichtung konnte auch der Kraftstoffverbrauch verringert werden. Mit der ersten 32-Bit-Motorsteuerung, der Trionic, wurde dieses Konzept 1993 auf einem höheren Niveau weiter verfolgt. Das Tri im Namen steht für die drei Anwendungsgebiete: Zündkennfeldsteuerung, Kraftstoffeinspritzung und Ladedrucksteuerung. Natürlich verarbeitet das System mittlerweile auch Daten von TCS- bzw. ESP-Steuergeräten. […]
