                               Staff Report

                             October 23, 1981

Evaluation of the Western Carbide‘s "Fuel Miser" Water Injection
System in Accordance with Section 2222, Title 13, of the California
Administrative Code.


I.    INTRODUCTION

      Western Carbide of Stanton, California, has applied for an exemption

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

an add—on device known as the "Fuel Miser" water injector.     This

exemption is being requested for all 1981 and older gasoline—fueled

engines.

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

1975 (CVS—75) tests.

II.   DEVICE DESCRIPTION AND OPERATION

      The "Fuel Miser" is a vacuum—controlled water injection system.      The

major components of the system are two nozzles which mount in the spacer

plate under the carburetor, a water bag, and a control valve,

      The control valve (Figure 1) consists of a vacuum—actuated diaphragm

which is connected to a manifoid vacuum source and a "reverse taper"

needle valve which controls the water flow.     The needle is calibrated

such that no water flow occurs during idle, deceleration, and mild

acceleration.   The vaive opening is then inversely proportional to

manifold vacuum.


III. APPLICANT‘S TEST RESULTS

      The applicant submitted hot start CVS—72 data from a 1978

Datsun 280Z and cold start CVS—75 data from a 1981 Mercury Zephyr.        These

data are:

      Vehicle No. 1, 1978 Datsun 2807, 2.8L automatic transmission,

Device                .26           _2.84             .45        17.0

% Difference       ~10.3           +10.1            +7.1         —2.4

IV.   DISCUSSION

      The principle of operation of the "Fuel Miser" control valve avoids

the major problem (encountered in vacuum—operated water injectors) of


flooding the engine with excessive amounts of water during low demand

periods.   Although the device is called the "Fuel Miser", no other claim

of fuel economy is being made,.

      The CVS test data indicates no significant increase in emissions or

fuel economy occurred as a result of the installation of the "Fuel Miser"

on either carburetor—equipped or fuel injected cars.

Vv.   CONCLUSION AND RECOMMENDATION

      The staff finds no evidence to indicate that the "Fuel Miser" water

injection system will have a significant adverse effect on emissions from

a motor vehicle.

      The staff, therefore, recommends the approval of Executive Order

No. D—116 exempting the “Fue] Miser" water injector from the prohibitions

of Vehicle Code Section 27156.
