The "Grieve 1907 "20 hp
... Heir to a Presbyterian family tradition related to Engineering and Mechanics, born in Lima in 1878
Juan Alberto Grieve. His grandfather, the Scottish engineer George Grieve arrived at Peru in the 1840's, hired for the construction of the railroad Tacna - Arica. His father John Chrysostom Engineer Downing Grieve had worked on the design and construction of Central Railway, the most important engineering work IXX century in Latin America.
While his grandfather and father were products of the Industrial Revolution, Alberto was a man of the twentieth century. Graduated with honors at age 20 as a mining engineer in 1898, his vocation took him to the Mechanical and Electrical. He had the gift of uniting academics with deep knowledge of the best manual dexterity Mechanical Workers, to which is added his knack for drawing, both mechanical and spatial and artistic. Alberto finished his studies began working at The Mint, chemical engineering, but also built three-phase electric motors of their own design. Get started the twentieth century to built a continuous current dynamo 5Kw with which lit up the currency.
diene and in 1905 built the first internal combustion engine aq continent heciendo a description of it in the bulletin of the Ministry of Public Works as a 4-stroke single cylinder engine, water cooled, capable of producing 5 CVA 1.500 RPM. The engine had an aluminum crankcase, cylinder, rings, piston and other components of cast iron. With improvements produced a large number of similar engines for water pumps, as well as electric generators. Subsequently underwent two-cylinder engine and then with one of four, consisting of two blocks of two cylinders with a common sigueñal.
in Lima in 1907 there were about twenty cars and engineer Grieve was the owner of an Oldsmobile Curved Dash, with a single cylinder engine of 4.5 hp., Two-speed transmission and a wooden body. It was the first car produced by volume in the world: A fabaricadas 10,000 units between 1902 and 1905. With this car Grieve took part in the first "raid" outside Lima, which joined Paseo Colon to La Punta in May 1907.
Last year, Grieve along with four other fans had founded the "Automobile Club", which brought a new sport enthusiasts. Besides working in the Mint, Grieve divided his time between the city of Lima, where he worked pro bono on issues of electrical, mechanical, trams and shoots, and giving lectures related to electricity and mechanics in the School of Engineers and the National School of Agriculture. Moreover, in his studio, the best equipped in Lima, experimented with machines, manufactured and produced their prototype motors, generators and water pumps. Grieve
decided in 1907 to design and manufacture your own car. At that time the few cars on Lima - French, Italian or American - had engines that produced less than 10 hp. Grieve considered making a car with a more powerful engine and 4 cylinders.
It developed an engine that had automatic valves, dual ignition, four spark plugs, magneto Sims Bosh lines. He made a four cylinder in line desaxiados in 18 mm. and a stroke of 110 mm., capable of producing 20 hp. A 1.800 rpm. Also developed a transmission comprising a gearbox 3 speed and reverse a leather cone clutch and shaft drive. The engine was cooling through a water cooler type honeycomb and thermosyphon system. The start was made by a crank.
The chassis was made of steel beams "L" in a ladder structure with all elements bolted. It had a wheelbase of 3 meters and both the front and rear track width of 1.30 m. It was equipped with wheels of 815 x 105 and inflatable tires Michelin. Had a braking system acting on the rear axle suspended by leaf spring.
The body, painted dark green, it was metal and could become a "Phaeton" of 5 seats in a "Roadster" ... Thanks
