STATE OF CALIFORNIA AIR RESOURCES BOARD, RESOLUTION 69-14 Whereas, in 1968 the California Legislature amended Section 27156 of the Vehicle Code to provide for operation of vehicles on fuel other than gasoline where the emissions are at levels which comply with existing emission standards, and Whereas, in August 1968, the Air Resources Board staff, on instructions from the Board, published a demonstration program for systems operating on fuel other than gasoline to show compliance with emission standards, and Whereas, on February 10, 1969, Marvel-Schebler Division of Borg-Warner Corporation submitted test data from such a demonstration program on two models of Century carburetors utilizing liquified petroleum gas (LPG); Now, Therefore, be it Resolved, that this Board finds that the emissions of engines equipped with Century carburetors listed below comply with existing standards, making these carburetors legal for use in California on both light and heavy-duty vehicles of 1966 through 1969 model year for those engine sizes listed below: Carburetor model 3CG-706-LE_. 3CG-705-DTLE__ Engine sizes 200-300 cubic inches. over 300 cubic inches. STATE OF CALIFORNIA, AIR RESOURCES BOARD, STAFF REPORT, EXHAUST EMISSION CONTROL DEMONSTRATION FOR LIQUIFIED PETROLEUM Gas Carburetors, MARVELSCHEBLER DIVISION OF BORG-WARNER CORP., MARCH 19, 1969 Marvel-Schebler Division of Borg-Warner Corporation has submitted test data in accordance with the attached program to demonstrate that two models of Century LPG carburetors comply with existing emission standards. These data are shown below: Each test vehicle in the fleet met the emission standard. Based on the test data submitted by the applicant, the staff finds that the Century carburetor models listed comply with existing emission standards. The staff, therefore, recommends adoption of Resolution 69–14. [Inter-office Correspondence] MARVEL-SCHEBLER, Decatur, Ill., January 13, 1970. To: R. N. Little. From: E. J. Svoboda. Subject: NOx Values on LPG Vehicles. On January 8, 1970 the Western Liquid Gas Association sponsored a test for the purpose of determining the NOx reducing potential of LPG fuel. A total of ten vehicles, converted from gasoline to LPG fuel at sometime in their history, were picked to represent the majority of engines operating in the Los Angeles area. The tests were conducted by Olsen Labs, Inc., 5037 Telegraph Road, Los Angeles, California, using the official 7 mode cold start. The results were as follows on the attached page. 41-711 0-70-11 E. J. SVOBoda. Senator CANNON. Thanks very much. We appreciate your appearing here and giving us your views. We have two statements to submit for the record, one from Mr. Arthur M. Mackwell, Public Relations Officer, Engelhard Minerals and Chemicals Corp., which will be made a part of the record and another one from Mr. Edward Knapp, Anti-Pollutant Controls, Inc., both of which will be submitted for the record. (The statements follow :) STATEMENT OF ARTHUR M. MACKWELL, ENGELHARD MINERALS & CHEMICALS CORP. Mr. Chairman and members of the committee, it is the conviction of many, if not most experts on automotive air pollution that we will have to deal with this source of pollution within the broad parameters of the internal combustion engine as it is now in use. No other power source either has or gives promise of having the performance characteristics presently provided by the internal combustion engine. And the traveling public has given no indication that it will accept significant changes in the performance it presently obtains from the products of Detroit. It is our purpose here, as briefly and with as little technical obfuscation as is consistent with clarity, to suggest that a catalytic exhaust purifier will provide the foundation for an emission control system which will meet the most stringent standards which can reasonably be set. The catalytic exhaust purifier and the emission control system which can be structured upon it, using presently existing technology, are wholly compatible with the gasoline powered internal combustion engine and will not significantly affect its performance. To put that another way, in principle we can clean up the exhaust on current model automobiles using existing technical development. And we can do it for far less than the 25 percent premium cost that the bill presently under consideration allows. There are presently several catalytic exhaust purifiers on the commercial market. Without question, the best catalytic agent for these purifiers is a platinum group metal. This statement will deal with the performance and potential of the PTX and PTX-D Purifiers made by Engelhard Minerals & Chemicals Corporation, which has a platinum group metal catalyst deposited on a ceramic carrier. The PTX Purifier is designed for internal combustion engines powered by liquid propane gas or unleaded gasoline. The PTX-D Purifier is designed for engines powered by diesel fuel. The primary uses of the PTX and PTX-D Purifiers to date have been on fork lift trucks and on stationary installations in confined spaces or in other circumstances where purity of air is especially important. For example, thousands of purifiers are in use on equipment used in warehouses, ship holds, mines and food storage or handling depots. Another example, one major industry has asked its supplier of emergency generators to design this equipment so that a PTX purifier can be installed without modification of the exhaust system. In this industry, the emergency generator exhaust often is located near the air conditioning intake. The State of California is the only state to have a certification program for vehicles designed for use in confined spaces. The PTX Purifier has been certified for use in conjunction with liquid propane gas fueled vehicles following exhaustive test procedures conducted under the supervision of the California Air Resources Board. The reductions in carbon monoxide and hydrocarbons which are obtained by use of the PTX Purifier with unleaded gasoline can be readily ascertained by perusing these test results on a fork lift truck in use in a major brewery. |
