The fuel system feed your engine the gasoline/diesel it needs to run. If anyone of the parts in the system break down your engine will not run. Let's look at the major parts of the fuel system, Fuel tank: Basically a holding tank for your fuel. When you fill up at a gas station the gas travels down the filler tube and into the tank. In the tank there is a sending unit, which tells the gas gauge how much gas is in the tank. Fuel pump: On newer cars the fuel pump is usually installed in the fuel ...

I receive a lot of questions regarding oil and the least understood part is the number system used to rate oils. Oil weight, or viscosity, refers to how thick or thin the oil is. The temperature requirements set for oil, by the Society of Automotive Engineers (SAE) is 0 degrees F (low) and 210 degrees F (high). Oils meeting the SAE's low temperature requirements have a "W" after the viscosity rating (example: 10W), and oils that meet the high ratings have no letter (example SAE 30). Oil is ...

The drive train serves two functions: it transmits power from the engine to the drive wheels, and it varies the amount of torque. "Power" is the rate or speed at which work is performed. "Torque" is turning or twisting force. Multiple ratio gearboxes are necessary because the engine delivers its maximum power at certain speeds, or RPM (Rotations Per Minute). In order to use the same engine RPM's at different road speeds, it is necessary to change the "Gear Ratio" between the engine and the ...

Since Murphy or whoever it was, took credit for the round wheel, rolling technology has changed somewhat. Today, friction whether static or dynamic, is reliant on bearings to reduce motor or engine load. What is sometimes overlooked is the inherent features and design of a bearings to reduce temperature where it is not necessary. The basic requirement is to reduce contacting surface areas. More extreme requirements are to reduce vibration, reduce allotted space required to house such a bearing, ...

To buy a used car is a great idea for saving money. Everyone knows that a new car lost 65% of its value in the first 5 years. But the case would be more extreme for a 1 to 2 years old car, it will lost its value 30-40%. If you don't mind to drive a used car (I mean a 2 to 5 years old car, it looks pretty new) rather than a new car, you may save much money to pay many other bills. If you want to keep the car not too old, you may resell it after driving for 2 to 3 years and buy another newer one. ...

With the escalating price of gas, buying a fuel-efficient car makes a lot of sense. Approximately 15% of new car buyers reject a model due to poor gas mileage. Nearly 40% of those consumers who eliminate a full-size SUV due to gas mileage ultimately purchase a midsize SUV instead, while nearly 20% purchase another model altogether. (J.D. Power and Associates, Sept. 2004.) But even if you don't currently own a fuel-efficient car, there are lots of ways you can improve the fuel efficiency of ...

In late 2004, the Hudson Institute conducted a survey with the following results: 75% of Americans prioritized "reducing our reliance on foreign oil" over "cheaper prices for oil and gas." 83% of Americans agreed that "reducing our dependence on foreign oil must be a top priority for the next administration." 91% of Americans concurred that "when it comes to energy, we need an America that relies on its own ingenuity and innovation-not the Saudi royal family." How much oil we depend on from ...

FUEL CELLS & ALTERNATIVE FUEL VEHICLES The history of the fuel cell can be traced back to the 19th century. Since then the development and usage of fuel cells in a variety of applications have come a long way. Fuel cells hold great promise for fueling alternative fuel vehicles. Here is some of the history of the development of fuel cells: William Grove invented the fuel cell in 1839. General Electric invented proton exchange membrane fuel cells in the 1950s Francis Bacon demonstrated a 5kW ...
