| dc.description |
To meet the existing and proposed legislation for the control
of air pollution by the exhaust emissions of petrol engines, a
major research effort is required within the next five years. Not
only are the regulations expected to become more stringent as the
number of motor vehicles increases, but improvements will show a
diminishing; return in terms of the percentage reduction of emissions
when primary factors have been treated. A fundamental problem that
is not well understood is the effect of the quality of the fuel-air
mixture on combustion in the spark ignition engine. Knowledge of
this factor could be important when the emissions are at a low
level as a consequence of the employment of devices that treat
factors such as mixture strength or the distribution of the fuel.
Although the devices are effective in the reduction of the concentrations
of hydrocarbons it is thought that many have an undesirable
effect on the concentrations of the oxides of nitrogen.
To improve the knowledge of these problems, it is the proposal
that the research at the Advanced School of Automobile Engineering
should be extended to a comprehensive study of the effects of
mixture quality on the concentrations of carbon monoxide, hydrocarbons
and oxides of nitrogen in the exhaust gas of a spark
ignition engine. The facilities at the School are comprehensive
and no financial assistance is requested for equipment. To allow
the study to be completed within a time that is relevant to the
urgency of the problem, a grant is requested for the employment of
a Senior Technical Officer and a Laboratory Technician for a period
of three years. |
