NATS 1840 – Lecture 14 – The Automobile - The automobile is pervasive & integrated in North America - Pervasive: millions \owned, millions produced - Integrated: birth and death occur in cars, as well as conception, work, eating, we do almost everything we do elsewhere in cars - Cars have been around since before most of us born - restrictions on use: licensing and cost of operation - Cars are intertwined with pop culture, North American values; they are indicators of individual freedom and economic prosperity, sign of adulthood - altered urbanization, expansion reinforced car Current Concerns about The Automobile - Internal combustion engine, gasoline, greenhouse gasses - Scale of automobile use, exhaust as an environmental and health problem - The Kyoto accord reduction of greenhouse gas 6% below 1991 - Reducing car emissions, targets, reduce total number, reduce pollution of individual cars. - Hybrid cars now available, electric cars are soon promised - Changing design of car to solve problem is “technological fix” - Changing the way cars are used (carpooling) is social fix Kirsch and the Electric Car - Electric, gas & steam cars, turn of century - 1898 a New York Sun article stated that, At that busy corner, Grand Street and the Bowery, there may be seen cars propelled by five different methods of propulsion – by steam, by cable, by underground trolley, by storage battery and by horses. [Kirsch, 11] - 1885 Gottlieb Daimler & Carl Benz, liquid benzene fuel for cars - 1887, Rudolph Diesel, compressed fuel injection - Commercial electric and steam cars predated gasoline powered cars - First electric car in 1894, electric cabs in NY in 1897 Steam, Electricity and Internal Combustion - Turn of century, steam power well developed, 150 years experience with steam engines & trains, thermodynamics - Electrical technology: electromagnetic theory, electric trams, lighting, power generation and battery development from the laboratory tradition meant that electricity was very well understood - Internal combustion less-developed technology, less experience, benefited from science (thermodynamics & chemistry), and steam technology - Chemical industry, petrochemicals, dye technology (printing and textiles), established industries and old traditions Internal Combustion Development - Internal combustion engines initially less reliable & efficient - Technological achievement of internal combustion - Rudolf Diesel, … traced the origin of the engine he invented to his training at the Munich polytechnic. In 1878 he heard a lecture there on Carnot’s theorem concerning the ideal conditions for expansion of gases in an engine’s cylinder… this ideal, as he later wrote, ‘pursued me incessantly’. [Pacey, 172] - Carnot’s scientific work, Diesel engine, steam engine data - Carnot’s increase in temperature increased efficiency of heat engine, gasoline burnes hot The Competition - Science (chemistry, thermodynamics, electromagnetism), technology (steam engines and electrical motors) - horse & automobile - between 800,000 and 1.3 million pounds of manure each day in New York City - Automobile, technological fix - Automobiles expensive, heat and cold, further and faster than horse - expanding populations, manufacturing and production, shipping capacity - Automobiles and horses, military and commerce, WWII, rural and poor Steam Cars - Lighter, high pressure & temperature - Steamboat, train boiler explosions 1800’s, stigma - Steam flexible , gasoline, kerosene, wood or coal - Pure water, clogging, unreliable, expensive to fix, and too dangerous Electric Cars - Electric engine flexibility, 2-3X rated power (hills, mud), gasoline stall - Stopped & restarted easily, commercial use - Fueling, technical & organizational challenges - 1909 over 4000 central charging stations over United States - Standardization poor, charging technology unreliable - Electric industry ignored, vanity technology - Batteries: limited storage capacity, charging times varied - Long distance rail shipping, local by automobile, electric cars sufficient - Markets expanded, greater range of internal combustion advantage - Electric motors: frequent small adjustments by experts - Private clients, speed, range & performance, commercial clients wanted cost-effectiveness and a respectable range Internal Combustion Cars - Internal combustion lighter, higher speeds, accidents, wear and tear, social menace, initially constant breakdowns - Simpler to fix, little technical knowledge - Sensitive to fuel impurities, engine problems until fuel standardized - Gasoline & kerosene widely available, heating and lighting - Long distance touring (private users), before gas stations - Infrastructure investment not needed in the beginning Wartime Influences - Standardization of parts, “American system of manufacture” - Military firearms industry in mid-1800’s - 1913, Henry Ford, mass production, standardized parts - WWII, military internal combustion, range and simplicity Gasoline as a Fuel - Mid-1800’s, oil in US, chemical analysis at university, commercial applications - Early 1900’s, electric lighting replacing kerosene, need for new demand - Gasoline: low flash point and a high temperature of combustion - Cracking method, gasoline from crude oil - Oil has complex, heavy, long chain molecules, “cracked” or broken down to produce lighter kerosene and gasoline - By 1911, chemists working for oil companies developed methods to crack petroleum using high temperatures and pressures - Improvements eliminated “knock”, increased efficiency & purity Advantages of Internal Combustion - Private users liked range, simplicity; ease of fuelling - Electrical industry ignored car market, failed to standardize - Oil industry saw demand for cars, innovated to meet needs - Businesses liked range & reliability for growing urban population - Military adoption of gasoline engine gave it early support - Chemical improvements: cheap, plentiful and efficient fuel - Population growth, cheap automobiles, the desire to travel far and fast, all contributed to the demand for the internal combustion car - Expanding urban population also demanded products & services, this drove the commercial adoption of internal combustion vehicles Kirsch’s Argument - Electric car initially more flexible, comparable range for most applications, and of sufficient speed - Gasoline cars were more prone to breakdowns (knock, stalling, general), less reliable, easier to fix - Improvements expected for electric, success of industry - While waiting, consumers chose IC cars IC cars then improved, uel & engine efficiency - “waiting” for competitive battery, IC dominated market, standard technology The Rise of the Internal Combustion Automobile - 1913 - 1929, annual car & truck manufacturing increased from 1/2M to 4.5M+, most internal combustion - By 1914 35,000 electric & 1.5M internal combustion cars. - Federal, state & industrial investment in car infrastructure: roads, fuel, repair facilities, parking lots, traffic police, courts, insurance - 1927, annual car-related deaths 21,000+, injuries higher - WWII contributed to the domination of the IC automobile - Postwar industrialization & rising populations increased demand, oil price shocks in 1970’s, improvements in production & design, no significant reduction in demand Lessons from the Past - People expect long distance travel, speed, standardized parts - Industry, commerce, labor and urban development, fast, fuelefficient vehicles. - Hybrid cars and performance requirements. - infrastructure, charging technology, road infrastructure - Effect of attaching millions of electric cars to electricity grid - 25% of electrical power in Canada fossil fuel generated - electric cars: traffic volume, accidents, urban planning
