That’s why there are clubs called Honda Civic clubs exist. Here is a little analysis of Honda civic. You may find several or few facilities in other car, but Civic has all of these and that’s why it is become a car which all car lovers talking about.

  • Value for the Money
Among the giants in the automobile industry, there are number of names which are considered as branded and excellent products.  But with their price and actual value of the product it is a doubt is the product worth for that price. There are number of products which are not value for the money.  Those companies make value on their name but not on the specification and the features of the product. But few car produces value the product as it really values. Honda Civic is one among them. The cars with those features and facilities value more than this. This is one good reason to love Honda Civic.
  • Impression
Impression is one of an essential requirement of the car which gain value to your life. No doubt BMW, Mercedes Bens has that value, it looks professional and powerful. But as a car lover it is very much essential to have a sporty look with the professional look.

  • Durability
Consider the vehicle made in 1990’s which are still in the road, You may noticed there are few models, but you may noticed there are several Honda Civics among those models. It shows the durability of Honda Civic. There is some Civics made before 1990’s which is on driving condition and pass the emission test also. It explains how a durable car it is.
  • Power and driving feel
Honda Civic is a powerful road runner which gives wonderful driving feel that is because of its variation and the driving support which is designed to given when in driving.  It has its own driving power which can trill the driver and make him the feel of  a excellent driving condition, that makes feel  on Civic users  to not to change the car. That kind of a excellent drive feeling cannot be gain from any other car which is in the road.
  • Variation makes good choses

Google self-driven car

In the field of automobile industry this is one of a giant invention which was considered as a task that can never be able to achieve. The experiment is done by Google which is never heard in automobile field. The experiment was a secret in the past but now it is well-known project which is among number of success projects done by Google. Toyota prius is the vehicle which is used in the experiment.  This is one of a brilliant intelligent system developed in the world history.  Unfortunately it was faced to the first accident in few days ago, but actually it was happened due to the fault of the other driver who is involved in the crash.  But before that it has driven more than 160,000 miles without an accident, for this distance they used several different types of roads like highways, busy (city) streets, mountainous roads. It is really excellent achievement. Anyhow this post is for describe the technology of the car. 

Google Autonomous prious

The major difficulties in the project are to get the idea of the distance of the obstacles and understand all those obstacles to avoid accident and drive very carefully. When driving in the real environment it is huge challenge, considered to the specially designed environment.  Because there are number of moving obstacles in several distance with several speeds. The challenge is to collect all those detail and synchronize with those details (obstacles). Google autonomous car is designed to overcome those problems. For that is has several sensors and algorithms. 

Sensor system of the car

  • Laser range finder
This is mounted in the roof of the car and using this laser ranger car understands the range of the obstacles in the road which the vehicle is driven in. This range finder uses laser rays to create obstacle map in every single location and get the idea of all the moving and stable obstacles in the current path. As Google engineer Chris Urmson said it is the heart of the vehicle and by processing all those details taken from the laser range finder.

  • Four radars
These radars are mounted in the front and rear bumpers of the car. These radars help to get the idea about quickly and instantly moving objects which is very important in the driving. So using this car can get the idea about pedestrians and bicycles and all those quickly moving objects.  These radars are help to avoid the accidents happened due to quick moving.
  •  Video camera
This camera is mounted near the rear view camera, to detect all the traffic light signals. By using the camera it gets all the traffic light systems and understands the traffic lights which are suitable for the way vehicle is driven.
  •  GPS system
This is also mounted in the roof of the vehicle and, by using this GPS device vehicle understands the initial location of the vehicle. This is the most accurate way to understand the location of the vehicle.
  •  Position estimator
This is mounted in the rear wheel of the car and understands the movement of the car. This is a simple sensor that detects rotation of the wheel. This is very essential for breaking and determines the speed of the vehicle.

Anyhow Google achieve the great task in the automobile industry.  Before publicly (commercially) use the car there are many features to upgrade and added to ensure the safety and increase the efficiency. It is always consider about the security and efficiency, In junction even though light signal allow the vehicle to move forward and to turn any side if there are people crossing the road vehicle is waiting until the last person cross the road. The car is that much advanced. 

Finally it will become very advanced technology but there is an issue, even though it makes people to move without driving. It is in future people will lose their driving capabilities and it will reduce the adventure of driving. It is not a bullshit in future drivers will lose their jobs and people who enjoys from driving loss their fun.

The most Powerful Diesel engine

In the history of automobile technology people invented number of miracles which were very important to human activities. In the field of engine, it is really a vast area which is full of advanced and high-tech inventories. Among those there are several advanced designs; The Wärtsilä-Sulzer RTA96-C is considered as the most powerful diesel engine ever builds.  Basically the engine is turbo charged two stock diesel engines which contains 6 to 14 cylinders. The engine is designed for huge container carriers (ships).


Technical details:

Engine type:                       turbocharged two-stroke diesel straight engine, 6 to 14 cylinders
Cylinder bore:                     960 mm
Piston stroke:                      2500 mm
Engine displacement:           1820 litres per cylinder
Engine speed:                      92–102 revolutions per minute
Engine length:                     89 feet
Engine Height:                    44 feet
Torque:                              7,603,850 newton metres@ 102 rpm
Mean effective pressure:     1.96 MPa@full load, 1.37 MPa@maximum efficiency (85% loads)
Mean piston speed:             8.5 metre per second
Specific fuel consumption:  171 g/(kW·h) (126 g/(bhp·h), approx. 3.80 litres per second) @ full load
Power:                              up to 5720 kW per cylinder
Power density:                   29.6 to 34.8 kW per tonne, 2300 tonnes for the 14 cylinder version
Amount of fuel injected in a single cycle of single piston: ~160 g (about 6.5 ounces) @ full load
Crankshaft weight:             300 tons

The usage of the engine is for huge container ships which needed high power single engines. The engine is available with 6 to 14 cylinders as the user needs. There are specially designed oil pumps and injectors for keep the engine cooled. It was a new design that is not usually using in the industry.
