But How Does it Work?

Ram 2500 at All Star Dodge Ram near St. Louis

Have you ever wondered how the engine on the Ram 2500 at All Star Dodge Ram near St. Louis works? Today we would like to provide you with a basic explanation on how the engine works. Remember, there is a lot more going on under the hood of the Ram 2500 than what we can explain here, but we think you are going to like learning about these powerful engines.

Most pickup trucks sold today have internal combustion engines. Passenger vehicles are powered by two main types of engines: compression, aka diesel, and spark ignition, aka gasoline.

Both spark ignition and compression ignition engines can work on a two- or four-stroke cycle. The more common of the two for automobiles, and certainly pickups, is the four-stroke. If we follow the path of the air entering a four-stroke engine, the strokes (or stages) in order are:

  1. Intake: The piston moves from top dead center to bottom dead center with the intake valve(s) open. If fuel is injected into the throttle body or intake manifold, then it is pulled into the cylinder with the air. If fuel is directly injected, then it may be injected near the end of the intake stroke and into the beginning of the compression stroke.
  2. Compression: All valves close and the piston moves from bottom to top dead center. Near the end of the compression stroke the spark plug fires, igniting the air-fuel mixture.
  3. Power: The piston moves from top to bottom dead center with all valves closed. The air inside the cylinder expands from the combustion of the air-fuel mixture. This provides the driving force for the engine.
  4. Exhaust: The piston moves from bottom to top dead center with the exhaust valve(s) open, pushing the exhaust out. (This information is compiled from news.pickuptrucks.com.)

Dodge Ram Used Cars – Perfect for Long Term

Used Cars at All Star Dodge Ram in MIssouri

It is widely known that Dodge has been innovator in the auto industry since the early days, as in the early days of the car itself. It is this long legacy that makes each Dodge Ram model such a great vehicle. They are built to last. This means that when you decided to by a Used Car from All Star Dodge Ram in Missouri, you are getting a vehicle that will last you a long time. We want to share with you a little bit about the Dodge brothers that started this long lasting legacy.

The Dodge Brothers were skilled machinists from a modest background. John Francis Dodge and Horace Elgin Dodge were two of the three children of Daniel Rug and Maria Dodge of Niles, Michigan. They attended public schools, but learned the machinist’s trade from their father, who ran a shop specializing in internal combustion engines for marine use. The inseparable brothers built the first bicycle in Niles.

Horace Dodge invented a four-point, dirt proof, adjustable bicycle ball bearing and in 1897 the two brothers established the Evans & Dodge Bicycle Company with Fred S. Evans and leased the Typograph Company plant for two years. In 1900, they sold their interests, returned to Detroit, and established a machine shop in the Boydell Building on Beaubien Street at Lafayette. They began with only twelve employees, but quickly established a reputation for excellent workmanship. Ransom E. Olds erected the first automobile plant in Detroit in 1899 and by early 1901 the Dodge machine shop supplied him with engines. Olds followed with an order for 3,000 transmissions in 1902, making the Dodge brothers one of the largest parts suppliers for the nascent Detroit automobile industry.(Some of this information was compiled from dodgemotors.com). The Dodge brothers grew their knowledge from a small bike shop to a manufacturing empire.

2014 RAM Heavy Duty

new Dodge Ram HD in MOAll Star Dodge Dealer offers a wide selection of heavy duty new Dodge Ram trucks in MO such as the 2014 Ram 2500. 

Powertrain

In 2013 Dodge Ram HD’s diesel power was boosted to 800 lb. /ft. of torque for both its diesel and combustion engines.

The a 6.4 Hemi option for the Ram heavy duty trucks was predicted by auto experts, along with a new transmission to compete with the GM’s Allisons.

According to AllPar.com; “a CNG version of the Hemi engine was quietly added to Ram’s 2012 specs sheets for body builders, only on the Ram 2500 pickup (4×4 with crew cab, ST or SLT, trim, long bed, automatic, and 3.73 axle ratio).”  “After we broke this news in September 2011, Ram chief Fred Diaz denied that Ram was working on a CNG engine. In March, a dual-fuel CNG Ram 2500 was announced.”

New features in the 2014 Dodge Ram HD

New features in the newest Dodge Ram HD model include an optional air suspension setup

According to MoparNorm, “The air springs will be only on the rear axle, so there won’t be any impact upon turning radius. There will also be no ‘axle shift’ as the panhard bar prevents that and the control arms keep the axle in place front to rear. Look at the rear of a Wrangler or Ram 1500 and just imagine the coil spring replaced by an air spring, or look at the rear axle of most newer semi truck tractors.”

But perhaps the biggest change in the 2014 Dodge Ram 2500 is its increase in towing capacity of 2,000 lb. compared to the outgoing model.
