  • Mopar Automatic Transmissions

    Modern automatic transmissions can trace their origins to a gearbox that was developed in 1904 by the Sturtevant brothers. This unit had two forward speeds, the ratio change being brought about by flyweights that were driven by the engine. At higher engine speeds, high gear was engaged. As the vehicle slowed down and engine rpm decreased, the gearbox would shift back to low. One of the key developments in arriving at an automatic transmission was the use of planetary transmission in the...
  • Camshafts

    Camshafts are used to operate poppet valves. It consists of a cylindrical rod running the length of the cylinder bank with a number of oblong lobes protruding from it, one for each valve. The cam lobes force the valves open by pressing on the valve, or on some intermediate mechanism, as they rotate. Camshafts can be made out of several types of material. These include: Chilled iron castings: Commonly used in high volume production, chilled iron camshafts have good wear resistance since the...
  • The History of Car Antennas

    Automotive antennas have evolved since their introduction in the 1930s. Once tacked on as optional equipment, they are now designed into the car as an indispensable accessory. Several different approaches have been used to improve performance while making the antenna attractive, including embedded windshield versions and electric hide-away styles. The First Antennas In the 1930s, car antennas were incorporated into the radio body, as most stations were in the AM band, which required a...
  • Blind Spot Monitoring

    What is Blind-Spot Monitoring? Blind-spot monitoring one of those features we didn’t know we needed or wanted until carmakers began offering it. Volvo was the first, incidentally. It offered its Blind Spot Information System (BLIS) for the S80 in 2005. BSM is just what its name implies. It keeps an eye on the space just off the rear quarter areas of your vehicle. These blind spots can hide a vehicle approaching in an adjacent lane because many drivers improperly set their car’s outboard...

Driver Adaptive and related fuel table trim is probably the least...
  3. EV Charging & Battery Life

    Electric cars need to be recharged frequently for efficiency. However, charging an electric car is a much different experience than refueling a gas or diesel vehicle. Instead of a few minutes, charging an EV can take anywhere from 30 minutes to over 30 hours. This is because there are actually three levels of electric car charging. Levels of Charging NeoCharge provides a breakdown of the three levels of EV charging. Each level of charging is defined by the amount of voltage, which...
  4. New LED's for my 2009 R/T. Pictures do not do it justice!

    Well I've been waiting around to win the lottery so I could afford some LED tail lights. So just for giggles I bid 400 bucks for a set on eBay and the offer was accepted. I ordered my three layer center decal in advance so I put it on before the lights. It was a little tall so I just trimmed it before I took off the paper. I always wanted a blacked out rear end but I never liked those covers that went over the stock lights of the 2008 through 2014. I purchased the smoke set and it does not...

    Windshield Dots

    The small black dots on a car windshield are called frits, which are black painted enamel that’s baked onto the surface of the glass. Modern cars have a windshield bonded to the frame. He described how the windshield is bonded using a strong and long-lasting urethane adhesive, which makes the windshield a structural component of the vehicle’s body. The frits “provide a secure point of contact between the glass, urethane adhesive, and windshield frame. Essentially, the small black dots help...

  7. Li-Ion Batteries

    We are now entering the electric car age. These vehicles are powered by Li-Ion batteries. This type of battery is energy dense and durable. However, it can also be unstable and prone to catching fire under certain circumstances. But not all Li-Ion batteries are suited for vehicles. How Do They Work? Lithium ions store the energy by creating an electric potential difference between the negative and positive poles of the battery. Those are isolated using a separator material to prevent...

    The question frequently comes up, “Are E10 and E85 fuels harmful to my engine?” Here is everything you wanted to know about the chemical compound ethanol that is added to gasoline. Ethanol is used as an “oxygenate” and is added to fuel to help reduce hydrocarbon emissions that cause air pollution. It is highly refined beverage (grain) alcohol, approximately 200-proof, that can be produced from natural products such as corn, sugar cane and wheat. New technology allows ethanol to be made...
  14. Burnout Primer

    All drag racers spin their wheels in a burnout before every race. The burnouts may seem to be pure show-boating, but there are real reasons behind all the smoke and noise. Burnouts before a drag race serve to heat the tires of the car, softening the rubber, providing more traction for the start of the race. The burnout also removes any debris from the tires. Spinning the wheels leaves a layer of rubber on the road surface, providing better traction in the future. The burnout is crucial for...
