2010 Mazda B: Grab It Before It’s Over

Mazda B is simply the same old pick up truck maintained unchanged since 1994 at an affordable price of $15,795. This ranger truck provide features like airbags, antilock brakes, media player, manual 5 speed gearbox and a powerful 143 hp engine.

The base model is the SX trim with a 2.3 L engine. This is for those small town jobs which require a small pick up truck. But, the full version Cab Plus 4×4 SE model Mazda B is required for the tougher jobs. This model is priced at $24,395. The engine has been upgraded to 4.0 L V6 engine delivering 207 hp with a 5 speed manual gearbox. This can be upgraded to automatic gear system at a meager amount of $1400.

This four wheel drive is all equipped for the drive with tow hooks, fog lights, skid plates, allow wheels and air conditioning. As the name Cab Plus, this car can take four people in the extended cab. But the back seating will seem a little annoying with the seats placed face to face. The car is equipped with a cargo bed at the rear seat which can carry an ATV. With towing hooks, the car is best at towing with the automatic version giving a better performance than the manual model. The V6 engine used here is very well known for its towing and pulling capacity but at the same hand eats up a good deal of the fuel.

The interior has that same rich look without many much modification than its earlier version and Ford Ranger. The interior has been finished and fitted with industrial gray plastic. Be it manual or automatic, the gear layout is simple and easy to use.

There is a new variation to the SE Plus whereby the seats are replaced for more comfortable bucket seats along with an armrest in between. The model is priced at $20,800 with power window, a good torque steer, keyless entry, leather finished wheel, radio satellite and CD changer.

Far away from the $16,000 base price, one would easily land up at the $27,875 full fledged Mazda B4000. This has advanced features like freight, automatic gear system and A/C tax. The major competitor is the Ford Ranger, but news is that Ford will be stopping its production soon. Ford Ranger has a price lower than Mazda B by a few dollars. Other high priced competitors are Chevrolet Colorado, GMC Canyon, Nissan Frontier and Toyota Tacoma. The machinery and the purpose served is the same but they still have associated better features as higher the price. Sometimes, people even give up on choosing Mazda B for an F-150, Silverado or Ram 1500. The prices are the same and can serve the purpose of simple pick-up truck.

Even though the model is 15 years old, it works perfect as a recreational vehicle and pick-up van. If you seriously want a Mazda 2010 B, then make it fast and get your hands on the leftover lot at least.

 

 

Brand New Car Reviews: 2012 Jeep Wrangler With Pentastar V6 Engine

2012 Jeep Wrangler with Pentastar V6 Engine – Engine Upgrade

The Jeep Wrangler is a compact four-wheel drive SUV manufactured by American based car manufacturer Chrysler, under its Jeep marque. The 2012 Jeep Wrangler is the fourth generation of this series.

During Chrysler’s third-quarter sales announcement, the CEO of the company, Sergio Marchionne, stated that the 2012 edition of Jeep Wrangler is to receive the latest version of the Chrysler engine: the 3.6 liter Pentastar V6. This means that the 2012 Jeep Wrangler will join a long list of cars manufactured by Chrysler which have already received the powerful Pentastar V6 engine for their 2011 year model. The first car to use this engine is the 2011 Jeep Grand Cherokee. This engine has also been used in the 2011 editions of Chrysler 200, 300, as well as Town & Country; the 2011 editions of Dodge Avenger, Challenger, Charger, Durango, Grand Caravan, and Journey; and the 2011 Volkswagen Routan.

If this announcement is true, it means that the 3.6 liter Pentastar V6 engine will replace the old 3.8 liter V6 engine. The new engine will be able to increase the performance of the car. If the old 3.8 liter V6 engine can only produce up to 146 kW of power with 315 Nm of torque, the brand new 3.6 Pentastar V6 will be able to produce not less than 216 kW power with 352 Nm of torque. Despite the significant increase in performance, the new engine consumes similar amount of fuel as the previous engine. They both consume about 12 liter of fuel per 100 km.

2012 Jeep Wrangler with Pentastar V6 Engine – Other Features

Besides the engine upgrade, this car has plenty of other features to offer. The previous edition is available in two transmission options: the 4-speed Ultradrive 42RLE automatic and the 6-speed Chrysler NSG370 manual. For the 2012 edition, to keep up with the Pentastar V6 engine, the 4-speed automatic transmission will be replaced with a 5-speed automatic transmission system. However, this change is taken quite late since many manufacturers are upgrading their vehicles to 6- or 7-speed automatic transmission.

The standard features offered in this series include airbags, heated power mirror, Sirius Satellite Radio, as well as a GPS navigation system. As the 2011 edition is equipped with a new steering wheel, totally new interior design, leather upholstery, larger rear windows, and USB ports with Bluetooth connectivity, the 2012 Jeep Wrangler is predicted to continue to use these luxury features. Optional automatic temperature control will most likely be installed in the 2012 edition. This feature is intended to increase the driver and passengers’ comfort by controlling the temperature inside the cabin of the car.

As for the design, The 2012 Jeep Wrangler with Pentastar V6 engine is predicted to feature improved aerodynamics. Many experts predicted that the car will come with a streamlined windshield and front fascia design. This car will be available as a 2-door/2-seater and a 4-door/4-seater. It will also be available in three models: X, Rubicon, and Sahara.

 

 

Explanation of Common Rail Diesel Injection Systems

The common rail diesel injection system is a modern spin off of the direct fuel injection systems that were used in the past. On a diesel engine this system features an auxiliary high pressure fuel rail which feeds individual solenoid valves with up to 26,000 psi of fuel pressure.

The very first common rail diesel injection system was prototyped in the late 1960′s. The first successful usage of the system was in the mid 1990′s and was used on heavy duty vehicles and was eventually sold for general use in 1995. The Denso company lays claim to the offering the first common rail high pressure system also in 1995. The Bosch Company later refined the Common Rail Diesel Injection (CRDI) system. This revised system has a flexible division of a single injection into multiple pre and post injections allowing this type of system to be matched to individual engines in the best possible way to allow full combustion of the fuel delivery.

In general there is a high pressure fuel pump which creates pressure which it then stores in the systems accumulator, in many cases this accumulator is the actual fuel rail. The pressurised fuel is then fed through rigid fuel pipes into each individual injector, the injectors inject the correct amount of fuel in the form of a fine mist into the combustion chambers of the engine. The computer for the injection system is called the electronic diesel control unit or EDC for short, this controls all of the parameters of the injection system such as rail pressure, the duration of the injection and also the timing in which the injectors fire to release the fuel into the combustion chamber.

The use of piezoelectric or solenoid valves make it possible to have very fine control over the fuel injection quantity and timing, this coupled with the high pressures of the CRD system provide exceptional fuel atomisation which allows the vehicle to run cooler, burn the fuel more completely and be more environmentally friendly. In order to make the system quieter the ECD can inject a small amount of diesel just prior to the main injection event, this reduces the explosiveness and vibration inside the engine and improves cold starting. As a result, modern CRD systems require very little or no warm up time while producing much less noise than previous systems.

Different car manufacturers call the CRD system by different names, examples include: Ford Motor Company’s TDCI, GM/Opel/Vauxhall’s CDTi, Honda’s i-CTDi, Isuzu’s iTEQ, Mazda’s MZR-CD, Mitsubishi’s DI-D, Renault’s dCi, and Toyota’s D-4d. There are other variations out there but for the most part you get the idea. While they may be the same system, each manufacture renames the system in order to try to differentiate itself from the others.
