  • System, sensor combination and method for regulating, detecting as well as deciding current fuel-air ratios in combustion engines
    Patent number: 6526954
    Abstract: A system for regulating the fuel-air mixture in a multi-cylinder internal combustion engine. The system utilizes binary sensors to detect relative deviations from stoichiometric combustion, including individual combustion events, and allows for regulation to achieve optimal and similar combustion to take place in all the cylinders.

  • Method and device for gas sensing
    Patent number: 6109094
    Abstract: A gas sensing device having a semiconductor substrate, wherein the semiconductor substrate is covered by an insulator layer, on which an intermediate layer is formed, and subsequently covered by a gas sensing catalytic layer, wherein the intermediate layer and the catalytic layer are made of different materials. The gas sensing device may optionally have dispersed between the insulator layer and the intermediate layer a catalytic metal layer. The gas sensing device provides improved stability and speed of response, even when used at high ambient temperatures, such as temperatures found in combustion systems. A method for making the gas sensing device is also disclosed.
