  • Exhaust system of an internal combustion engine
    Patent number: 6557341
    Abstract: In an exhaust system for an internal combustion engine having two groups of cylinders with a separate exhaust line for each cylinder group, each including an upstream catalytic converter and a downstream catalytic converter and a control valve, a first transverse connection extending between the exhaust lines upstream of the upstream catalytic converters and a second transverse connection extending between the exhaust lines between the upstream and downstream catalytic converters, the valves are so arranged and controlled that, during warm-up, the exhaust gases from both cylinder groups flow through the upstream catalytic converter of one, and the downstream catalytic converter of the other exhaust line for rapid heat up of one of the catalytic converters in each of the exhaust lines.
    Type: Grant

  • Spark plug for forming a spark to jump between two electrodes
    Patent number: 5950584
    Abstract: A spark plug for forming a spark that jumps between two electrodes has an insulating body surrounded by a housing with a ground electrode. The insulating body has a center electrode therein, which projects beyond the ground electrode in the axial direction.
