STS 3700 – Lecture 12 – Alternatives to the Internal Combustion Automobile,

- Automobile pervasive & integrated in North America

- Licensing & operating costs, freedom & prosperity, urbanization

- Gasoline, greenhouse gasses, number of cars

- Changing design “technological fix”, changing use “social fix”
Kirsch and the Electric Car

- Competition between electric, gas & steam cars at turn of century

- 1898 New York Sun article,

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 engines

- 1887, Rudolph Diesel added compressed fuel injection

- First electric car in 1894, electric cabs in NY in 1897

Steam, Electricity and Internal Combustion


- Steam: 150 years, steam engines & trains, thermodynamics

- Electricity: EM theory, trams, lighting, power, batteries

- Internal combustion parasitic on existing science technology

- Chemical industry & petroleum, internal combustion & tradition



Internal Combustion Development


- IC less reliable & efficient than steam or electric

- IC technological achievement, 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]

- Science and technology, analysis of steam engine data

- Temperature and heat engine efficiency, gasoline
The Competition

- Science (chemistry, thermodynamics, electromagnetism), and technology (steam engines & electric motors)

- Competition between horse & automobile

“In the late 1890’s horses passed between 800,000 and 1.3 million pounds of manure each day in New York City”

- Technological fix for horse pollution, expense, operation in heat & cold, range & speed, population, manufacturing & production

Steam Cars


- Lighter, high pressure & temperature for efficiency

- Boiler explosions, stigma, gasoline, kerosene, wood or coal

- Pure water, unreliable, expensive to fix, and too dangerous

Electric Cars


- Flexibility, power, stopping and restarting, commercial use

- 1909, 4000 charging stations in US, standardization

- Industry interest, battery storage capacity, charging times

- Automobiles and rail shipping, expanding markets

- Expert maintenance, private and commercial clients

Internal Combustion Cars


- IC engines light, high speeds, accidents, wear, social menace

- Breakdowns, simplicity, technical knowledge and repair

- Fuel impurities, standard fuel, gasoline & kerosene for heating

- Touring and infrastructure investment

- Standardization of parts, “American system of manufacture”

- 1913, Henry Ford, mass production with standardized parts

- WWII, military chose internal combustion, range and simplicity
Gasoline as a Fuel

- Oil analyzed by chemists, commercial applications

- Electric lighting & kerosene, IC & demand for gasoline

- Gasoline: low flash point and a high temperature of combustion

- Complex, heavy, long chain molecules, must be “cracked” or broken down to produce lighter kerosene and gasoline

- 1911, cracking methods with high temperatures & pressures

- Improvements eliminated “knock”, increased efficiency & purity
Advantages of Internal Combustion

- Private users: 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

- Expanding urban population demanded products & services

Kirsch’s Argument


- Electric car initially more flexible, comparable range & speed

- Gasoline cars & breakdowns (knock, stalling, general), repair

- Improvements expected for electric, success of industry

- Consumers adopted IC while waiting, improvements in efficiency



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, postwar industrialization & rising populations

- 1970’s oil price shocks, production & design, demand


Lessons from the Past

- People expect long distance travel, speed, standardized parts

- Industry, commerce, labor and urban development and car

- Performance requirements and infrastructure.



- Cars & the electricity grid, traffic volume & accidents
