Alternatives in the car industry Car makers reflect global turn towards environment-friendly technology.
Outline • Problems with fossil fuels • Oil • Introduction to the alternatives fuels • Examples of present hybrid cars • Toyota Prius • Lexus • Hydrogen – fuel of 21st century • Summary
Fossil fuels How long could they last?
Reserves of states How long would last the state reserves? Most of oil resources lie in instable region of Middle East.
Introduction to the Alternatives • Clean and efficient petrol engines • Hybrid electric vehicles • Alternative fuels • Fuel cell
Clean and efficient engines Cleaner fumes • filters of solid content (CO, CO2, NOX) located in the exhausts • catalyzers (hydrocarbons) More efficient engines = lower consumption • direct injection of petrol (all modern diesel engines, recently also petrol engines - FSI) • high-tech construction design and materials, electronic management European norms called Euro 3, Euro 4 and Euro 5 which strictly set pollution standards for engines in all new cars. American system Low Emission Vehicles, eg. ULEV (Ultra Low) are 50% cleaner than the average new model year vehicle. Zero LEV are 98% cleaner. Leaders: Peugeot, BMW, Volkswagen
A combustion engine+ an electric motor with a Battery which recharges automatically when braking. Electronic driving management effectively combines both types of engines. • improve fuel economy • lower emissions • trendy style Leaders in the Czech Rep: Toyota Prius, Lexus RX400h
Alternative fuels • biodiesel (biologically produced diesel) • electricity (do not forget to plug your car in!) • ethanol • hydrogen • methanol • natural gas • Propane Emission reductions of up to 80 percent for various pollutants. No ambition to become a successor of petrol. Being used in specific areas (agriculture, countries).
Fuel cell Considered to be the solution for future. Generate energy using a reaction of oxygen and hydrogen producing no pollution, just water and heat. Several technological and logistic issues to be resolved. Leaders: Toyota, Honda, Ford
Toyota Prius • The first hybrid car on the market • prices (USA vs. CZ) • Popularity and interesting facts
Lexus - world leader in hybrids Combines luxury and high-powered V6, V8) engines with hybrid motors, which they claim changes a paradigm. First hybrid SUV in the world, the RX400h was introduced a year ago.
GS450h A direct competitor of Audi A6, BMW 5 and Mercedes E.
Hydrogen engines • Differences between Hydrogen and Hybrid engines • Combustin vs. Fuel-cell conversion • Ways to obtain hydrogen • Leaders: BMW,DaimlerChrysler, Ford,Honda etc.
Summary • Oil problems • Cleaner petrol engines, more hybrid vehicles (Lexus, Toyota) • Future lies in hydrogen
