Ford's, fo ur-wheel .dr ive Lynx Ford of Canada's hlgh- technologyfront-wheel- drive Lynx are powered by an all-new four-cylinder overbead-cam Compound Valve Hemispherical (CVH) engine that coSt $1 billion to develop. The 1.6-litre CVII englng la expected Wo have Transport Canada approved ratings of 5.3 litres per 100 kilometres (53 miles per gallong) in hlghway drivlng .and 6.7 litres per 100km (42 mpg)lin comblned city/bighway driving. Development of the new engine - described as a "lheml-head" because of Its hemlsphericaliy-shaped combustion chambers - began in the early 1970's when a Ford Sclentific Research Laborator>' team was formed to ldentlfy a powerplant for the 1980's. After a design concept was- establlshed, Ford's new hlme-head engine was com- pared with 25 other wedge and pre-chamber engine designs considered to represent the world's best engine techology. The CVII engine proved superior in terms of both fuel-efficiency and power output. Becaiuse of its vast ex- perlence with small passenger-car engines, Ford of Europe supervised sub- sequent development of the new CVII engine. Ford of German>' worked on refinements Wo the basic engine design and Ford of Britian handled performan- ce development. A five-man task force from Ford's Nor- th American engine engIneerng operations hiac responsbilit>' for ensuring that design, development, durabillty and feaslbillty ob- jectives were met for the North American market. the result of the worldwide engineering effort was the smallest engine in the histor>' of Ford in North America, but one which also produced one of the highest horsepower ratingsa per cublc centimetre of dispiacement. The secret is the engine's ability to "breathe" - the hemni-head design and compound, valve angles facilitate the largest possible valve openlngs in the combustion chamber. The engine also is excep- tionall>' dean. Piston crowns are fully machined and contoured to set up a "squish" effeet on air and fuel enterlng the, chamber, providing a better mix and more efficient combustion than more conventional designs. Placing the spark plug dloser to the center of the chareber also con- tributes to more efficientý combustion. The valvetrain system - operated b>' a single overhead cam - is unique to Ford's hime-head design and Ford has applied for a patent on the concept. The carburetor is a two-barrel Holley-Weber mnodel 5740,, and the cylinder head and intake manifold are both aluminum for lighter weight. The* CVII engine will be manufactured at Ford's totall>' renovated Dearborn (Mich.) Engine Plant, and at a Ford of Europe engine plant ln Wales for European Escorts. B13y6, the U.S. pn'lant wlU hav nuallzed capacil ve an an- than one million engines and umPi*ptY for imore than t>' of more the Welsh plant will have 500,O OOgie. Merceury Lynx Ford of Canada's new front-wheel-drive world car Mercury Lynx, will be among the most fuel- efficient cars available in Canada, Ro>' F. Bennett, president, said toda>'. "We are confident that these high-technology car, equipped with the 1.6-litre engine, will have a Tran- sport Canada-approved citylhighway comparative rating of 6.7 litres per 100 kiometres (42-miles-per- gallon) and a highway rating 0f 5.3 litres per 100 kilometres (53-miles-per- gallon). Lynx, whlch combine the latest techeological advan- ces fromn Ford's worldwide engineering faiities, will be introduced in Canada on Oct. 3, Mr. Bennett said. t'Our dealers across Canada have indicated the>' can seil al of the world cars we can provide," he added. Lynx are aimed squarely at both, our imiport and domestic competitors. The>' are precision-built automobiles that provide the fuel economy demanded b>' today's market as well as the performance, ride, han- dling, comfort and con- venience features Ford owners have come to ex- pect."9 Mr. Bennett said scheduled-maintenance re- quirements Lynx are amoung the lowest for an>' new car or truck on the market, with costs. projected to average less than $40 a year in the flrst five years or 80,000 km of normal driving. Lynx are also the most- patented cars in Ford's histor>', with 14 U.S. patents on varlous components already received and 21 ad- ditional patents awaiting approval. The new cars are powered b>' a dramaticaîlly new Com- pound Valve Hemispherical (CVH) engine-described as a "hemi". because of its hemisphericailly shaped combustion chamber-which was developed by Ford engineers in Europe and North America. The result Of the worldwide engineering effort was the smallest engine ln the histor>' of Ford in North America, but one whlch also produced the highest hor- sepower per cubic cen- timetre or dispiacement. "In addition to the nim- bleness expected of a small car, Lynx will privide the quiet, comfortable ride usuailly associated with much larger cars," Mr. Bennett said. "Because of its four-wheel fuil>' indepen- dent suspension, the>' will be able to 'stop over' rough pavement and potholes wlth much less pitch and body sway than small cars with solid rear axles.
