Chemicals and Consequences
that come from a diesel engine. -Dora Torres- Diesel History Rudolf Christian Karl Diesel
March 18,1858-September 29,1913 Diesel Engine Invented & patened in 1892. Influence; A higher toleration of efficiency. Theory: higher compression= higher efficiency= more power. Attended "The Technical University of Munich" !Current Research! 2 types of internal combustion engines: -Gasoline -Diesel Air intake,compression,fuel injection & ignition.
Ratio: 14:1 to 25:1 (higher efficiency).
Heat of compressed air ignites fuel.
Converts more fuel -> mechanical energy (better fuel economy & mileage).
Less acceleration, but live longer.
Higher torque. Fuel & air intake,compression,ignition (spark plugs).
Ratio: 8:1 to 12:1
Ignited by spark plugs.
Less fuel is converted -> mechnical energy.
Better horsepower. But they are both internal combustion engines. Gasoline Diesel Diesel Animation How does it work? Image courtesy Baris Mengutay Diesel The benefits What can it do? Transports LARGE objects Marine Ships School Buses City Transportation Locomotives Power Generators Mining Mechanisms Truck Transporter Composed of Soot Exhaust Concerns Which can lead to: Acid Rain
Health Problems Types of hazardous gases Gases You save up more fuel per gallon, which makes you save money. Acceleration Weight Burn up, light on fire. Ability to do work. Carbon Dioxide Carbon Monoxide/Oxide Nitrogen Dioxide Nitric Oxide Sulfur Dioxide IMPROVEMENTS Consequences Cardiovascular Effects Respiratory Effects Lung Cancer Nervous System Effects Premature Death Heart & blood vessels Respiration Carcinoma of lungs Nerves, Brain & Spinal Cord Early Birth Who Gets Effected? Causes of human cancer... Off-Road On-Road Railroad Workers Miners Loggers Mechanics Bus Workers Truck Transporters Firefighters Toll-Booth Collectors Catalytic Converter over LONG distances Device that is establised in an automotive's exhaust that has a catalyst that converts some pollutants into harmless compounds. & Alternatives... Biodiesel What is it? It's made from vegetable oils and animal fats. & produce less air pollutants. colorless, odorless gas yellow-brown liquid poisnous gas
