Electronic fuel injection raises the costs to $800, but improves the fuel economy by 5 per cent.
It recommended that fuel injection equipment in heavy lorries should be made tamper proof in line with regulations in other countries.
In that category, we shall face at least single point fuel injection, electronic ignition and secondary air.
In addition, a stainless steel exhaust, and in most cases, fuel injection equipment has to be fitted.
The need to fit controls of mixture strength, with electronic management of fuel injection, would be avoided.
Fuel injection equipment results in greater engine efficiency, which usually cancels out any loss of economy from the catalyst.
The motor companies, by increasing the use of fuel injection, after-burners and catalytic heat exchangers could make their contribution too.
They have other mundane uses for the mass markets, such as in controlling washing machines, in fuel injection systems of cars and in many military and defence uses.
