10 Supplement of the Canadýin Statesman, April 28, 1976 New mod--Pdel cars found cr-onsidierably cleaner They emit 70% less pollutants ïï in United Sta tes and Canada,,~ The newý-miodel automno- biles are running conisicr- abiy - clealier than their older counterparts, accord- ing ýto results of the first phase of a Champion Spark Plug Company's survey of cars in the United States and canada. David L. Walker, direc- tor of Champîon's Auto- motive Technical Services Department, said' a pre- Iiminary coxparison of 1,667 vehicles surveyed during the company's Fuel Economy and Emnissions Test indicated the new- mode! cars are emlitting about 70 per cent fewer pollutants than pire-1968 automobiles. Emissions lowered Emission levels of 1970- 74 cars are alsa lower, averaging 30 to, nearly 50 per cent below those of cars produced prior to 1968. Mr. Walker said, -The 1.25 per cent carbon mon- oxide (CO) and 162ppm hyclrocarbon (HIC) aver- ages of the 1975s we tested are indicative of the prog- ress that has been made in emission control." ile also pointed out that the test diagnosed one car in~ 30 as being a "gross emitter" - exceeding 10 per cent CO and 2,000 ppm HC, or higher than test instruments can measure. "While these cars repre- sented only a smnail per- centage of our survey, each 'gross polluter' emit- teçi more lIC than 13 av- erage 1975s," Mr. Walker explained, adding "the in- tests show among older cars is con- siderably higher, indicat- ing that inadequate main- tenadnce and vehicle age are contributing factors to excessive emissions."1 Tune.ups instrumental Champion's tests are showing a marked de- crease in emîssians follow- ing tune-up. Rýeductions averaged 30 per cent less CO at idie after tune-up and an average 70 per cent decrease in lIC under sim- ulated 55 mph road con- ditions. Tune-up was also instru- miental in increasing fuel economy. On the average, the nearly 75 untuncd cars tested reaiized nearly a 51,'2 per cent fuel savings after being tuned. A wide range of other information is being an- alyzed fromn test resuits. ,"We found emýission con- trol systemi comnponents- either inoperative or dis- connected in approximate- 'y 10 per cent of the U.S. cars we tested," Mr. Walk- er said. "This indicates a definite need for more conscientiotis mainte- nance on the partof the. car owner." Three-year prograi CHAMPION SPARK PLUG Company',, Mobile Proving Ground (M.P.G.) is continuing ils 30 city, international test program to determine the effects of tune-up on gasoline mileage and emissions. In carly findings, ils tests have shown that late-mdel cars are op to 13 times less polluting than pre-1968 vehicles and are stayingwellwithingovernment standards, for keeping the air clean.

The rallymaster's re- sponsibility is setting up the course-the route the rally covers. He draws up and furnishes ail entrants with the general instructions for the rally. Especially in fun rallys, the rallymaster uses his imagination to add to the difficulty and joy of the- sport. A rally might be a map rally. if so, each team will be furnisheu with matching, road maps, but with differ- ent instructions and chai- slenging dlues regarding the changes of direction.
