Emissions Control
Engine efficiency has been steadily improved with improved engine design, more precise ignition timing and electronic ignition, more precise fuel metering, and computerized engine management.
Advances in engine and vehicle technology continually reduce the toxicity of exhaust leaving the engine, but these alone have generally been proved insufficient to meet emissions goals. Therefore, technologies to detoxify the exhaust are an essential part of emissions control.

Famous quotes containing the word control:
“Physical nature lies at our feet shackled with a hundred chains. What of the control of human nature? Do not point to the triumphs of psychiatry, social services or the war against crime. Domination of human nature can only mean the domination of every man by himself.”
—Johan Huizinga (1872–1945)
