1 FUEL SYSTEMS Mr. Lombardi, Selig, Moffre

2  The purpose of the fuel system is to supply an exact amount of fuel for the engine to burn.  Without this essential system, a car wouldn’t be able to run. The Purpose of A Fuel System

3  Fuel tank  Fuel line  Fuel filter  Fuel pump  Fuel injection system Air Cleaner

4 Fuel Tank  Usually two pieces of steel, welded together to form a container  Can also be made of plastic.  It will have a fuel pickup in the deepest part  Filler neck  Vent to allow air back in  Gauge  Fuel pump

5 Fuel Lines  A fuel line is a hose used to bring fuel from storage tank to the distribution center. (Carb/Injectors)  Commonly made of steel or high density plastic.

6 Fuel Filter  Screens out dirt and rust particles from the fuel, normally made into cartridges containing a filter paper.

7 Fuel Pump Fuel has to be pumped from the fuel tank to the engine under low pressure to the carburetor or high pressure to the fuel injection system.

8 Fuel Delivery  Carburetor  Fuel Injection

9 Carburetors  TWO JOBS  to mix the air and fuel  control the speed of the engine.

10 Fuel Injector squirts fine mist of fuel into the combustion chambers of the engine. A computer controls the system, monitoring necessary factors (load/RPM). Fuel Injection

11 Diesel Fuel Injection  Fuel injection “Timing” is critical

12 Fuels  Come from Refined Crude Oil  Organic Compounds  Gasoline  Diesel  Alt Fuels

13 Gasoline  Aliphatic hydrocarbon.  Hydrogen and Carbon arranged in chains

14 Octane  8 Carbons chained together  Adds length to Gas chain  Knock deterrent - resistance of the fuel to self- igniting

15 Diesel  Similar to Gasoline (Carbon chain)  Much longer (more energy)

16 Alt. Fuels  Ethanol  LP  CNG  Bio Diesel

17 Ethanol  High Octane  Clean burning  American-made  Renewable fuel  $$$$ Distill  Energy Neutral

18 Propane Injection System  Requires another complete fuel system  average loss of 5 to 10% in miles per gallon  104 octane rating  domestically produced fuel  70 % less hydrocarbons (smog)  50 % less carbon monoxide  20 % less NOx  % less CO2

19 CNG  Similar to LP  Refueling Station more $$$$  40 % cheaper than Gas

20 BioDeisel  Mixed with Petroleum Diesel Fuel  Long chain fatty acids derived from vegetable oils or animal fats  Made from agricultural co-products and byproducts  soybean oil  natural oils  Greases
