PAGE 4-PLAINDEALER-WEDNESDAY, NOVEMBER )5, 1972 Revolutionary Engine Welcomes Motorists to New 'Rotary' Club Welcome to the rotary club -- the rotary club of Dr. Felix Wankel, whose revolutionary new engine made its appear­ ance in Germany in 1956, and is possibly going to be the power plant for many auto­ mobiles in ten years. The rotary-powered Maz­ da, made by Toyo Kogyo Company in Hiroshima, Ja­ pan, has already made its appearance in this country with the RX2 sedan. Experts in the automobile industry say there is a real possibility that domestic made rotary-engined cars will be in the nation's show­ rooms on a limited basis by 1974 or 1975. Sooner or later you may be driving -- maybe even own­ ing -- one of these remark­ able cars, so youll want to know a little about what makes the engine go. It's a gasoline-burning, in­ ternal-combustion engine which uses rotary motion to drive the wheels instead of the up-and-down motion of a piston engine. If you were to take the cover ofT the top of the rotary and look down into it, you would see what looks like a triangle turning inside a chamber which is shaped like a slightly flat­ tened circle. Three Chamber* Each side of the triangle blocks off an arc of the cir­ cular chamber to form three smaller, crescent-shaped chambers. As the triangle, or rotor, turns, the positions of the three crescent-shaped chambers move around in­ side the large, circular cham­ ber. The intake-compression - ignition-expansion-exhaust sequence occurs in the three crescent-shaped chambers, causing the rotor to spin. The rotor, which turns not on its axis but in a slightly eccentric motion, is attached to a drive shaft to turn the car's wheels. The rotary motion is al­ most vibrationless, and it constitutes one of the rotary HARM'S HELPS WITH YOUR CHRISTMAS GIFTING fc. - HOLIDAY FRUIT BASKETS - J Filled With: •WASHINGTON STATE RED * AND GOLD DELICIOUS APPLES •INDI VN RIVER PINK SEDDLESS GRAPEFRUIT •CALIFORNIA NAVAL ORANGES •CHIQUITA BANANAS •POMEGRANITE • PLUS NUTS, GRAPES, PINEAPPLES We will enclose a gift card and 4"to$19" engine's most significant ad­ vantages over the piston en­ gine. Ignition in the rotary is caused by two spark plugs. Because of Ujeurotiry's char- astgrirtiegrthe plugs have to function with a considerably reduced cooling cycle. To do the job properly an entirely new plug was developed by Champion Spark Plug Com­ pany. It has two ground elec­ trodes instead of the usual one. In addition, a copper- cored center electrode is used to permit the better heat conductivity demanded by the rotary. !No Pistons Dr. Wankel's creation has no pistons, as we said before; neither does it have a crank­ shaft, camshafts or valve gear. It is remarkable in that it uses about one-third the number of parts of a piston engine, is one-half the weight of the piston power plant, and develops the horsepower of a piston engine twice its size. Reasonable fuel economy .(on unleaded, low-octane gasoline) and acceptable oil consumption are characteris­ tic of rotary engines. What about service? If the engine is operated within the recommended range, the life of the seals and bearings should run between 60,000 and 100,000 miles. As the rotary state-of- the-art is perfected, that life should be extended. After you've joined the ro­ tary club you'll be pleasantly surprised to learn that for all its differences, the rotary still uses the same carburetor, wiring, tubing, alternator, ig­ nition system, etc. as the pis­ ton engine. The same tools are used to take it apart and put it back together again. And there's no problem of having to re-educate an en­ tire service and supply force. Any competent mechanic should be able to service the rotary after a week or two of instruction. 1. Chamber at minimum space volume. Intake cycle 2.

That is, if you know what you are doing and take some simple precautions. Battery technicians suggest the following procedures when using jumper cables. 1. Start the engine of the car used as the "booster.** 2. Connect one end of the " positive cable to the posi­ tive terminal of the boost­ er battery. Then put the other positive cable to the positive terminal of the disabled battery. 3. Connect the negative cable to the negative poet of the booster battery. Then con­ nect the other neg*M*« cable to the bumper, frame or engine block of the car to be started. 4. Now try to start the "dead" engine. Do not connect with the negative post of the disabled battery. The spark created by the connection could cre­ ate an explosion if there is an excess of gasoline fumes or raw gasoline present. Positive terminals are usu­ ally designated by + (plus sign). Negative terminals are usually identified by -- (mi­ nus sign). One last word of caution. If you are not certain you're doing it correctly, don't do it. Instead, call a professional service man. It could save you expense and trouble in the long run.

So you bought a new car with all the emission con­ trols on it Now, your mind's at ease about excessive emis­ sions. Well, it shouldn't be. Studies conducted by Olson Laboratories show that ac­ ceptable emission perform­ ance for most cars can be achieved and sustained only by proper maintenance and repair. The study showed that only those tune-ups per­ formed to reduce exhaust emissions are effective. Olson reported that high emissions can be lowered, in most cases, with engine ad­ justments and tune-ups per­ formed by a qualified service technician. The results of the studies, summarized in the Olson re­ port, suggested: FIRST, that the incorpora­ tion of emission controls on cars does not assure contin­ ued low emissions because the control systems tend to deteriorate in their perform­ ance; 8ECOND, with proper maintenance and adjust­ ments, vehicles will continue to operate with lower emis­ sion levels. Olson recommends the use of infra-red exhaust ana­ lyzer equipment by qualified service personnel in order that accurate inspection can be performed -- and for de­ termining corrective adjust­ ments, service or replace­ ment. This type of equip­ ment measures the hydro­ carbon and carbon monox­ ide emissions produced by car engines and provides oth­ er information about their performance and economy. Various ignition system malfunctions, which can be detected with this type of equipment, will usually in­ crease undesirable emissions and reduce performance and economy. The appropriate inspection and corrective measures sug­ gested by Olson include: CRANKCASE DEVICES A. Have a qualified service specialist, using an infra-red exhaust analyzer, test the de­ vice for satisfactory opera­ tion with the engine warm and at idle condition. B. Have the device cleaned, serviced or replaced accord­ ing to the analyzer reading and manufacturer's recom­ mended instructions. EXHAUST EMISSION CONTROL SYSTEM A. Have a qualified service attendant check all installa­ tion connections to the air pump, hoses, valves and air hi!?- Checking emissions of thousands of cars to amass their data, technicians at Olson Laboratories discovered one common factor: No matter how effective anti-pollntion devices are on cars, they still have to be maintained for lowest possible emissions. distribution manifolds while the engine is stopped. B. With the engine at a normal operating tempera­ ture, have the attendant check and/or adjust ignition timing, idle mixture and idle speed according to the ana­ lyzer readings and to manu­ facturer's specification. ADDITIONAL PROCEDURES FOR "UNCONTROLLED VEHICLES'* A. Have the service spe­ cialist measure idle rpm and adjust, if necessary, to a speed no slower than manu­ facturer's Specifications. B. Have the service spe­ cialist measure ignition tim­ ing and point dwell; adjust, If necessary, to manufactur­ er's specifications. C. Have the service spe­ cialist measure the air/fuel ratio and adjust, if neces­ sary, to between 12.5 and 13.5 to 1. • • • Olson Laboratories, Int., m subsidiary of Northrup Corpor­ ation, Anaheim, California, is an independent testing and manufacturing organisation specialising in automotive engi- , neering and motor emission studios. Inflation Can Be Helpful When You Consider Tires Remember how Dad always used to let some air out of his tires when the snow got over two inches deep? Grand­ pa had told him this would increase his traction. Now, a new generation has come along to tell it like it is. It's like this: Your tires ac­ tually lose some of their bite when you let air out of them. If you want good winter traction, put on a set of snow tires--maybe studded (where legal) -- or buy some chains. However you do it, do not ex­ periment with your tire pres­ sure. Besides the traction sit­ uation, underinflation can waste 20% or more of your gasoline. Here is another interesting phenomenon about tire pres­ sures. If you leave the cold north when the temperature is down around zero, driving into the tropical south where it is a lovely 80 degrees, your tires could become as much as eight pounds overinflated. Conversely, your tire pres­ sure will drop a like amount as you go from a warm tem­ perature to cold. The drop is about a pound for each 10 degrees. This is why you should not check tire pressures in a heated garage and why you should have the pressure checked about once a month -- especially as seasons change. The advantages of proper tire pressure checks are in­ creased safety, better han­ dling and longer, more even tread wear. (Mb#; ft $ 1601 NOV'72 M.P. 31 Individual or Boxed...
