                                Staff Report

                              January 18, 1981

Evaluation of the M.G.S., Inc. Morrison (Carb II) Gas Saver Device in
Accordance with Section 2222, Title 13, of the California Administrative Code


      M.G.S., Inc. of Oklahoma City, Oklahoma, has applied for an exemption

from the prohibitions in Section 27156 of the California Vehicle Code for

an add—on device known as the Morrison (Carb II) Gas Saver.        This exemption

is being requested for all 1982 and older gasoline—fueled engines.

      The device was evaluated by back—to—back Constant Volume Sampler

1975 (CVS—75) tests.


      The Morrison Gas Saver (Figure 1) is a supplementary carburetion

device which connects to the fuel (1) upstream of the fuel pump and the

PCV line (2).   Fuel is drawn into the Gas Saver by a negative pressure
within the canister and is     regulated by a needle, seat, and float

assembly (4, 5, 6, 7, 9) equivalent in design to that of a carburetor.

The fuel in the gas saver is absorbed by a sponge (10), and then
vaporized by engine compartment heat diluted by air entering through

the filter assembly (12) and drawn by intake manifold vacuum into the
engine through the PCY system Figure (2).        The filter assembly is fitted

with a check valve to prevent the escape of hydrocarbon vapor during

shut down.


    The applicant submitted cold start CVS—72 and HFET data from a 1980

Federal Pontiac Grand Prix and cold start CVS—75 and HFET data from a

1981 Oldsmobile Delta 88 and a 1980 Ford Station Wagon.    These data are:

      Cold—Start emissions data from vehicles 1 and 3 indicate no significant

increase in exhaust emissions.         Vehicle 2 appears to be marginal with

respect to NOx, however this reflects only a 3.3 ppm change in bag 2

concentration and is still 29% below the applicable standard.


      The staff finds no evidence to indicate that the Morrison (Carb II)

Gas Saver will have a significant effect on emissions from a motor vehicle.

The staff also finds no evidence to indicate that the Morrison Gas Saver

will save gas.

      The staff, therefore, recommends the approval of Executive Order
No. D—122 exempting the mwmagee injector from the prohibitions of Vehicle

Code Section 27156.
