EMISSION CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINES USING AN AMPLITUDE MODULATED SIGNAL |
摘要 |
<p>Emission control apparatus for a multi-cylinder internal combustion engine has an exhaust composition sensor disposed in a passage in common to the exhaust systems of the engine. The sensed concentration of the exhaust composition is modulated in amplitude by a bipolar pulsating signal at a frequency higher than the frequency of the sensed exhaust concentration. A statistical analysis indicates distribution of the ratios within a narrow stoichiometric window.</p> |
