WHITBY FREE PRESS, WEDNESDAY. SEPTEMBER 19. 194 PACF 17 Auto Guide AUTO FACTS (NC) - There's an automo- tive engineering conjuring trick something akin to squeezing a quart out of a pint pot. It's called turbo- charging. Hook up a turbo- charger to a small engine and the power outputcan be bumped up toequalthatof a much larger, normally- aspirated engine. And it can be done almost without penalty - fuel consump- tion is increased by a per- centage less than the gain in power and mechanical longevity is virtually unaf- fected when the boost, or pressure in the intake mani- fold, is kept modest. One of the big attractions ofsupercharging an engine with the turbocharger is - that it utilizes an otherwise waste product, the engine's exhaust gas. Exhaust gas flowing from the engine drives a small, high-speed turbine which in turn drives a small compressor drawing in either ambient air (in fuel-injected en- gines) or a fuel-air mixture What (as in engines wi th carbure- tors). The compressor out- put is fed to the engine in- take ports, increasing engine volumetric effi- ciency - the cylinders are packed with a charge on every intake stroke - and the power output is in- creased markedly. A device called a waste gate relieves the boost pressure when it attempts to climb higher than its designed limits, as when the throttle is closed abruptly. Because of the better burning of the charge which comes with turbo- charger use, combustion byproducts are cut and so engine emissions are re- duced. Engineers fron Gen- eral Motors' Buick Division give as the reason the fine atomization of the fuel by the turbocharger's com- pressor wheel and the bet- ter distribution of the fuel charge within the combus- tion chambers as a conse- quence. Buick Division has is turbocharging? been the pacemaker in GM's development ofturbo- charged automobiles. A side benefit from turbo- charger use is that it, para- doxically, makes for a quieter running engine. As the exhaust gases travel through the turbine they ex- pand, much as they do when they enter a muffler, and so exhaust noise at the tail pipe is noticeably reduced.

The new generation of cars, light trucks and vans that are rolling off the as- sembly lines are, by far, the most technically advanced, economical and the best en- gineered in industry his- tory. Snaller, cleaner and leaner running engines have squeezed so much from a drop of fuel that it's becoming next to impossi- ble for engineers toimprove mileage under the hood. In- stead, they're having to come up with aerodynamic changes for better fuel economy. Smaller is better The notion that smaller is better, that sparked the switch from big cars in the early 70s, remains the basis for increased sales of sub- compacts, scaled-down trucks and mini-vans in the 80s. Until about 1982, smaller also meant less powerful. Fortunately, that's no longer true; the perfor- mance engine is making a comeback. Ten years ago, the aver- age rear-wheel driven fam- ily car, whose metal body and frame construction weighed close to 4500 pounds, was powered by a thirsty V-8 engine. Today's front-wheel driven cars are made of light-weight steel alloys, plastics and alumi- num and powered by four or six-cylinder transverse- mounted engines. In order to gear up for the driving needs of the 80s, auto manufacturers have made major modifications to suspension systems and transmissions. Electronics are playing an ever larger part in new car design and construction. And many cars already have onboard computers. As time passes, and auto manufacturers from differ- ent nations share techno- logical know-how, factories and financing, there is emerging what industry- watchers call a "world car," whose design and construc- tion relect the flourishing cooperation that exists be- tween certain manufac- turers. A uniform high quality The beneficiary of all this shared enterprise is the new car buyer. Automobile manufacturing and assem- bly plants, usir. state-of- the-art robotics, ai irning out autos of unifoi high quality. It's the of precision. Computers now control ignitions, fuel systems, transmissions, air condi- tioners, heaters, cruise con- trol, braking, suspension, exhaust emissions, and plenty more. Some even talk. Now, if we could just get them to tell us what the industry has in store for us, in the years to come. John Walby trains auto- mobile technicians for Esso Petroleum Canada.
