State of California AIR RESOURCES BOARD Staff Report November 27, 1978 Evaluation of the "ROSCO" Device in Accordance with Section 2222, Title 13 of the California Administrative Code Introduction This staff report evaluates the "ROSCO" manufactured by Rosco Filter Air, 2666 Mark Lane, West Linn, Oregon 97068, and marketed by Four Star Marketing, Inc., P. 0. Box 188, Canby, Oregon 97103, for compliance with the requirements of Section 27156 of the California Motor Vehicle Code. Starting with a brief introduction to the device, this report describes its operation, the benefit claims the applicant makes, the test data submitted by the applicant and concludes with recommendations to enable the Executive Officer to arrive at a decision. II. System Description Rosco is an in—line filter for the PCY system. The blow—by gases are circulated through a pair of opposing vertically mounted stan— dard engine oil filters. The filters are screwed onto a cast aluminum bracket, which is mounted to the body of the vehicle (See Figure 1). These filters trap the liquid from the blow—by vapors, enabling a relatively clean vapor mixture to enter the intake manifold. In vehicles where the PCY valve is not mounted on the rocker arm cover, the "ROSCO" can be installed upstream of the PCV valve, thereby helping to keep the PCV vaive clean.

The device may be installed on all vehicles where there is an external PCV system. Since the bottom filter gets filled with oil first, the manufacturer recommends inspection of the bottom filter every 3000 miles and replacement every 6000 miles. III. System Evaluation The applicant submitted CVS—75 cold start emission and fuel con— sumption data. Back to back tests were performed at the Automobile Club of Southern California. The vehicle used was a 1978 Ford Thunderbird, 351 CID with the odometer reading 9939 miles at the start of the tests. The outcome of the tests are summarized in the table given below: Exhaust Emissions grams per mile HC CO NOx MP& 1978 Cal. Std. 0.41 9.0 1.5 — Baseline 0. 482 22.830 1.513 8.603 w/ROSCO 0. 392 24.693 1.347 8.994 percent change —18.7 +8.2 —11.0 +4.5 IV. Conclusion and Recommendation The staff is of the opinion that the ROSCO, forming a closed loop with the PCV system, will have little influence on the emissions and the fuel economy. The percent increase in the fuel economy and the CO emissions may be considered to be within the limits of test variations. The high CO base line emissions could be due to the car being out of tune at the time of commencement of the tests.

Since the crankcase blowby gases tend to increase with the engine wear and tear, the staff is of the opinion that the installation of the "ROSCO" will be—more beneffcial to older vehicles. The applicant . makes the following claims for the ROSCO. 1. Better Engine Efficiency 2. Longer Engine Life 3. Cleaner Engines. Even though the applicant has not submitted test data to substantiate these benefit claims, the staff is of the opinion that the performance of the "ROSCO" will have insignificant/marginal contribution to these claims. Based on this evaluation and the evaluations of similar devices in the past, the staff is of the opinion that the installation of the "ROSCO" on a vehicle will not cause any additional emissions and, therefore, recommends that an exemption be granted for the device from the prohibitions of the Motor Vehicle Code Section 27156. Executive Order D—86 has been prepared for the exemption of the "ROSCO".
