The Working of a Car Suspension System

Comments Off

How comfortable does a passenger in a car feel if the car is traveling at an average speed, and the road has cracks and gutters? Not very much. On the other hand, imagine a car traveling on the smoothest surface possible at a high speed. Comfort will be maximum. The first scenario can happen as long the driver or passenger wishes to have it. But scenario 2 is a little different.

Horizontal and vertical accelerations
Apart from the comfort factor, if a surface is too smooth, there will be no traction for the wheels and so, even at normal speeds, the car would slip away from its path or sometimes the tires would even lose contact with the ground. Thus, some vertical force (one can call it obstruction) is needed for the car to grip onto the ground and move. Therefore, in order not to cancel out this vertical force and at the same time reduce it to a certain level so that the vehicle does not suffer too much damage, a system called suspension is used.

The suspension system
The suspension system supports the weight of the frame and helps it to maintain contact with the wheels always. The parts of suspension system are

Car chassis
The chassis is a very important aspect in a suspension system. All components of the suspension system are located in it, and ‘chassis’ basically includes a suspension system. It is prominent because it directly participates in the process of suspension. Apart from other systems, the chassis contains the frame and the suspension system.

The frame
This is the basic, framework that supports the entire weight of the vehicle and forms a platform to hold all the other crucial working components in place. Basically, it forms the skeleton of the chassis.

Coil springs
This is the most common of suspension devices. It is basically a hard metal bar wound around an axis and it expands or shrinks according to the vertical movements of the vehicle.

Leaf springs
This a set of metal bars combined together into a unit. The bars are also called ‘leaves’.

Torsion bars
The torsion bar is that which uses the twisting properties of steel as suspension. The ends of he torsion bar is connected perpendicularly to a wishbone. When the wheels receive vertical force, the wishbone presses against the torsion bar and receives torsion.

The shock absorber:
A vehicle’s suspension system cannot be successful only with springs. With just the springs, there is no limit or control about how much the vehicle will bounce when it hits a bump. This can result in a lot of undesirable things like acceleration squat, body roll and sway. The shock absorber is the most important device of a suspension system. It uses dampening mechanism to keep the springs in control and provide adequate support to the frame.

Technical Features and Advantages of a ‘V’ Engine

Comments Off

The V-type of engine has two rows of cylinders at an angle usually of 90 degrees. The working of a V engine is similar to that of a flat engine except the angle. Different angles of a v-type engine gives rise to different levels of smoothness. Some steep angles of the engine combines the advantages of V and flat engines and also the disadvantages.

Its advantages are its short length, the great rigidity of the block, its heavy crankshaft, and attractive low profile (for a car with a low hood).

Since it is short, it is compact and can be mounted easily. It is desirable in a vehicle with a small hood since the engine can be fit without negotiating passenger space. This engine lends itself to very high compression ratios without block distortion under load, resistance to torsional vibration. In-line engines have cylinders arranged, one after the other, in a straight line. Overall, V type engines are better and more powerful.

Usage
V engines are both used in cars and motorcycles. It is a highly preferred one in motorcycles due to its compactness.

Types

V2 (V-twin): Has two cylinders mounted in a ‘V’ shape. Most of The V-twin connecting rods share the same crank-pin. The cylinders can either be off-set in two different planes or can be set in the same plane using the ‘fork and knife’ connecting rods.

V4: V4 has been used in vehicles very less compared to the other V engines. The only advantage it has is that it is small in size and still can produce 140 horse power.

V6: The V6 has 6 cylinders, three of them joining the other three at a right angle or an acute angle. Like all V engines, all the pistons rotate the same crankshaft. It is a commonly used basic configuration of engines in modern cars after straight-4.

V8: A V8 can be defined as two sets of straight-4 cylinders acting on the same crankshaft. They produce more power compared to a V6, but has the disadvantages of being costly and consumptive on fuel.

V10: A V10 is two straight-five engines coupled together. V12 is slightly more complicated and runs more smoothly, while a V8 is less complex and more economical. V10 is not found much in common purpose in cars, but highly used in F1 racing.

The other V engines are V10, V12, V14, V16, V18, V20 and V24 as of today, where the number after ‘V’ indicates the number of cylinders.

Great Choices of Small Cars 2013

Comments Off

There is no secret that increasing consumer demand for economical cars or vehicles has sparked a small car renaissance among United States automakers. Nearly five years ago, it was tough to find five entry-level small cars to recommend. If you are in market for the new economical car that does not feel small in value, the following cars should be on your preference list.

  • 2013 BMW 1-Series: With moderately priced compact cars, Audi and BMW have expanded their lineups and with the CLA Mercedes Benz will soon do the same. The Mercedes yet to come and the Audi A3 due for a redesign, so our favorite of the group is the BMW 1-Series. It’s enough with the base engine in 128i, but 300 horsepower turbocharged inline six cylinder in 135i makes it as a rocket. The 1-Series is offering most of the vaunted 3-Series handling prowess, but with a slightly lower price and a bit less refinement.
  • 2013 Buick Verano: Sometimes the brand image can hurt when small luxury cars built on an economy car platform. But with General Motor’s Buick Verano it is different. It is based on Chevrolet Cruze, which also made this list, but Verano offers quieter interior and even more refinement than Cruze. Available 250 horsepower turbocharged four cylinder engine adds muscle to natural athleticism of compact’s.
  • 2013 Chevrolet Cruze: The Cruze is the best small car from Chevrolet. It offers levels of refinement and quietness those are not just impressive for General Motors, but for the automotive market (in general). Base engine is fuel efficient, but the better choice is 1.4 liter turbocharged four cylinder. It provides better fuel economy (in the Eco trim up to 42 mpg highway) offers more torque, and quieter. Inexpensive and roomy, to the typical small midsize sedan, Cruze is an economical alternative.
  • 2013 Chevrolet Sonic: If Cruze is not the best small car then the Chevrolet has another ever built, Sonic. It is having the same engine choices as Cruze but in smaller package. Its lighter weight makes it more agile and quicker than its bigger sibling. The Sonic hatchback with the 1.4 liter engine and six speed manual transmission is sporty.
  • 2013 Dodge Dart: The Dodge Dart offers technology and refinement which we do not expect in the small car class. As a typical midsize car, it has much rear seat space. We like 1.4 liter turbocharged engine with manual transmission. But CEO of Chrysler feels that the dual clutch automated manual transmission is not right for the American audience. That will be correct with the release of forthcoming nine speed automatic transmission, which make Dart as good as any car in the class.

The other small cars that you consider of 2013 models are Ford Focus, Honda Civic, Honda Fit, Hyundai Elantra, Mazada Mazda3, Mazda MX-5 Miata, MINI Cooper, Volkswagen Jetta, Volkswagen Golf and GTI.

The Blind Spot Detection and Warning technology

Comments Off

This system consists of two radar units and it is similar to lane change assistance system. This technology devices are mounted invisibly to the corners of the rear bumper. From those two radar units one will operate as a system master and the other is configured as a slave. With the help of private data link, the data of both the radar units will combine with the sensor data fusion tracking algorithm.

On the sides of the car, the two radars are pointed well and this will detect the moving vehicle beside the car fitted radar. The area that contains five lanes is scanned. Compared to the lane change assistance systems, the range of the rear is shorter, but this BSP is very easy to install and lower in cost. So, this will optimize for the freeways and slow speed urban driving. This system gives very low false alarm rate and performs excellently.

This system performs, objective to lane mapping, tracking, the warning algorithms and detection algorithms and the extra customer code can also be integrated. This system requires no extra control units. This cost efficient master slave and innovative system design interfaces all controls and indicators and performs all the functions and also communicates with the vehicle data bus.

This radar sensors monitor the space behind the road and alongside the car, also display the visual signal which is near the outside mirror. This is to indicate is their any moving vehicle in the blind spot.

This system can withstand strain and monitors the areas that are difficult to see to avoid the hazardous situations to the driver. Read the rest of this post

What are the Dangers of Drunk Driving?

Comments Off

Drunk driving is very dangerous to anyone who drives after drinking alcohol. At anytime, they may get arrested as they tend to take more risks. This mostly happens with youngsters, who mostly drunk and drive and are responsible for many fatal accidents. Even though the penalties vary from state to state, for minors if the BAC is over 0.01, it results in DUI and the legal limit of alcohol for adults, which is over 0.08. Most drivers get arrested under DUI for an average of 0.16 BAC.

Drinking alcohol below legal age is illegal, most minors and teenagers are drinking alcohol, these days. Alcohol drinking and driving associated may lead to car crashes and kills a number of teenagers. This will also kill many innocent people. Drunk driving is thus dangerous.

For drunk-driving, even the first-time offenders also receive the fines and even we see many of them in jail and now the judges are mandated by state laws, by which they are to impose higher penalties for the repeated offenders. It is a continuous problem and is forcing the police to impose more restrictions and increase the penalties for the drivers who are drinking or have BAC 0.08 or more. This is not only fining the penalties but also sometimes the license will be suspended for 6 months and if the case is serious and repeated then it may for even 2 to 3 years. This will also leads to higher car insurance premiums and probation for 3 to 5 years etc. depends upon the case.

Affect of alcohol on you:

  • You loose the sense of distance and see double, your speech will slur.
  • From poisoning of alcohol you will get sick and sometimes even die.
  • Your inhibitions will be loosen that leads to make bad judgments, which results in car accidents, violence etc.
  • This will also cost you your freedom, you can lose your driving license, grounded by parents and even end up in jail.

Drinking alcohol causes dehydration, but most of you think that it will quench your thirst. Read the rest of this post

Types of Cars Based on General Classification

Comments Off

Every car is categorized into a specific classification. The classification is for the purpose of taxation, size of the vehicle and its function. There are many classifications for vehicles. The manufacturing companies and other organizations create separate classifications of vehicles for different reasons and requirements.

Sometimes classifying cars is not easy. For the purpose of describing vehicles, automobile manufacturers and organizations use some basic categories. To determine different aspects of vehicles and for tax purposes, vehicle classification is made by the National Highway Safety Traffic Administration and the Federal Highway Administration. These standards are generally used by automobile industries.

  • Subcompact cars: Subcompact cars generally in 165 inches or 4191 mm in length. And the weight is less than 2500 lbs. As per the United States Environmental Protection Agency, the subcompact car has between 85 cubic feet and 99 cubic feet of interior volume. These are smaller than a compact car and larger than a micro car.
  • Compact cars: These are larger than the subcompact cars and smaller than the mid-sized cars. As per the United States Environmental Protection Agency, for international models approximately 175 inches or 4450 mm. And for the United States it is 161 inches or 4100 mm long.
  • Mid-sized cars: Mid-sized cars have the facility to accommodate 4 or 5 passengers. The weight of a mid-sized car is between 3000 lbs to 3499 lbs. The design length is between 110 cubic foot and 119 cubic foot. These are larger than the compact cars.
  • Full sized cars: These are larger than the mid sized cars. It has the facility or comfort to accommodate at least six or seven people. Full sized cars built weight is 3500 lbs. These are with a length of 102 cubic foot or more.
  • Station Wagon: Station wagon is also called as estate car. They are comfortable to sit and can accommodate 5 or 7 people. These can be classified as compact size, mid size or full size. The station wagons have extended interior with a third seat or extended rear cargo area or luggage platform accessed through car. In that place we can carry small and midsized items. The station wagon cars in the early days used to collect the people and their baggage from railway station because of its advertisement. Some of these cars are still consider as passenger carrying.

Before you buy a car check with these classifications. Based on the members the car will accommodate you can choose a car after inquiring with different companies on different models. Read the rest of this post

Impact of Hurricane Sandy – Civic Services Shut

Comments Off

The devastating hurricane Sandy has left millions of people in US shattered. The country is facing many difficulties in the aftermath of hurricane Sandy. People are trying to overcome the situation boldly and get back to normalcy.

Millions were shivering in cold without power and food to eat. Nearly 80 to 100 homes were destroyed, dozens of people were killed and thousands of people were evacuated to a safer place. To have a control on the heavy traffic, the police imposed curfew in many cities, so that people will be safe in their homes from the hurricane.

It is also reported that many of the victims who were killed in the storm mainly due to the uprooting of trees that fell on their homes, cars and on the victims. Overall, it is estimated that at least 88 people have lost their lives in US due to the heavy winds and rains.

Nearly 20,000 flights were forced to cancel, because of Sandy, due to which millions of dollars were lost in revenue. Civic services including public transport were suspended, because of no power and fuel. Schools, colleges and offices were closed, as it was difficult for people to commute from one place to another. The government have declared a state of emergency and has asked people to cooperate with them during these crisis. The rescue work is on in bringing conditions to normalcy.
